Description

Technical Field

[0001] The present invention relates to the fields of engines, engine equipment and vehicles, and in particular to a fluid curvature engine, a fluid curvature engine equipment and a control method thereof. Background Art

[0002] Common engines include internal combustion engines, steam engines, gas turbines, and turbo engines, but they suffer from low efficiency and a poor power-to-weight ratio. This results in vehicles and equipment using traditional engines being inefficient and often experiencing power shortages.

[0003] Existing rotors or propellers generate driving force by applying a force to the fluid and obtaining the reaction force of the fluid, but the thrust-to-weight ratio is small and the lift is insufficient. Summary of the Invention

[0004] The purpose of the present invention is to provide a fluid curvature engine, a fluid curvature engine equipment and a control method thereof, which fully utilizes the principle that the viscosity of the fluid and the inertia of the high-speed fluid work together to block the atmospheric pressure to produce a low-pressure area in the descending curvature area of ​​the upper convex surface to generate lift, and aims to solve the problem of low thrust-to-weight ratio and insufficient lift of existing engines.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a fluid curvature engine, comprising a disc shell, a multi-convex ring disc wing, and a high-speed fluid generator, wherein the multi-convex ring disc wing is disposed on the inner cavity surface of the disc shell, or a plurality of protrusions with curvature arcs are directly disposed on the inner cavity surface of the disc shell, and the multi-convex ring disc wing is integrated with the disc shell to achieve disc fusion;

[0006] The flying disc shell is an annular or disc-shaped open semi-cavity, the multi-convex ring disc wings are annular or disc-shaped, and the upper surface of the multi-convex ring disc wings has multiple protrusions with curvature along the circumferential fluid flow direction, and the high-speed fluid generator is a device that can output high-speed fluid;

[0007] Each of the protrusions with a curvature arc is similar to a single-convex wing, and the multi-convex ring disc wing is equivalent to a combination of multiple wing sections connected in sequence in the direction of circumferential fluid flow in the manner of leading edge to trailing edge;

[0008] The high-speed fluid generated by the high-speed fluid generator is sprayed at a certain angle toward the multi-convex ring disc wing in the flying disc shell. The high-speed fluid sprayed into the flying disc shell can circulate in the flying disc shell and repeatedly flow through the upper convex surface of the multi-convex ring disc wing, so that the multi-convex ring disc wing is in a relatively high-speed fluid, making the aerodynamic environment of the multi-convex ring disc wing similar to that of the wing of a fixed-wing aircraft flying at high speed in the air. The viscosity of the fluid and the inertia of the high-speed fluid work together to block the atmospheric pressure and generate corresponding multiple low-pressure areas in the descending curvature area of ​​the convex surface of the multi-convex ring disc wing. The pressure difference between the upper and lower surfaces generates corresponding multiple lift areas on the multi-convex ring disc wing, so that its maximum lift-to-drag ratio can be several times higher than that of existing single-convex wing aircraft. The descending curvature area starts from the stagnation point of the wing leading edge and extends backward along the convex arc to the area where the arc curvature no longer decreases.

[0009] Wherein, the high-speed fluid generator is a device capable of outputting high-speed fluid, and the high-speed fluid generator is any one of an internal combustion engine and a steam engine, or a combination of several thereof;

The high-speed fluid generator is arranged inside the flying disc shell, which is called a built-in layout, and the high-speed fluid generator is arranged outside the flying disc shell, which is called an external layout.

[0011] The nozzle of the high-speed fluid generator is of any one or a combination of fixed or movable types; the nozzle of the movable high-speed fluid generator is an adjustable structure, and the size of the nozzle and the relative angle and position with the multi-convex ring disc wing can be adjusted;

[0012] The multi-convex ring disc wing is any one or a combination of fixed and movable types. The size and number of the curvature protrusions of the movable multi-convex ring disc wing can be adjusted according to the fluid flow rate; the fluid is any one or a combination of gas and liquid.

[0018] The fluid curvature engine of the fluid curvature engine space shuttle, fluid curvature engine spacecraft, fluid curvature engine rocket, fluid curvature engine cruise missile, and fluid curvature engine loitering missile can be configured with an unpowered passive high-speed fluid generator in addition to a powered high-speed fluid generator.

[0019] The fluid curvature engine can be installed independently on the equipment or integrated with the equipment;

[0020] The fluid curvature engine equipment is any one or a combination of fluid curvature engine vehicles, fluid curvature engine engines, fluid curvature engine generators, fluid curvature engine airborne equipment, fluid curvature engine space shuttles, fluid curvature engine spacecraft, fluid curvature engine rockets, fluid curvature engine cruise missiles, and fluid curvature engine cruise missiles.

[0021] The fluid curvature engine generator is any one of a wind curvature engine generator, a gas curvature engine generator, and a steam curvature engine generator, or a combination of several of them.

[0022] The fluid curvature engine vehicle is any one or a combination of a fluid curvature engine car, a fluid curvature engine ship, a fluid curvature engine submarine, a fluid curvature engine aircraft, a fluid curvature engine flying vehicle, or a fluid curvature engine flying saucer.

[0023] The fluid curvature engine aircraft is any one of a fluid curvature engine airplane, a fluid curvature engine flying car, a fluid curvature engine flying ship, a fluid curvature engine flying train, a fluid curvature engine Airbus, and a fluid curvature engine aerospace plane, or a combination of several of them.

[0024] The high-speed fluid generator of the fluid curvature engine airborne equipment is an air-gathering structure, which is in the shape of a trumpet with a larger front and a smaller rear. The air-gathering structure uses the relative high-speed motion between the fluid curvature engine equipment and the fluid to press the fluid in from the large front opening, accelerates the fluid using its own trumpet-mouth convergence structure or Laval tube structure, and then sprays the high-speed fluid from the small rear opening of the air-gathering structure at a certain angle toward the multi-convex ring disc wing in the flying disc shell. The high-speed fluid sprayed into the flying disc shell can circulate in the flying disc and repeatedly flow through the upper convex surface of the multi-convex ring disc wing, so that the multi-convex ring disc wing is in a relatively high-speed fluid, making the aerodynamic environment of the multi-convex ring disc wing similar to that of a fixed-wing aircraft wing flying at high speed in the air, thereby generating corresponding multiple low-pressure areas in the descending curvature area of ​​the convex surface of the multi-convex ring disc wing, and then generating corresponding multiple lift areas on the multi-convex ring disc wing, thereby enabling the fluid curvature engine airborne equipment to generate controllable lift, ensuring that the fluid curvature engine airborne equipment and the equipment it carries can land smoothly and controllably at a low speed.

[0025] The high-speed fluid generator of the fluid curvature engine and the fluid curvature engine generator can use the gas collecting structure to accelerate fluids such as wind, steam, and gas.

[0026] Among them, the fluid curvature engine of the fluid curvature engine space shuttle, fluid curvature engine spacecraft, fluid curvature engine rocket, fluid curvature engine cruise missile, and fluid curvature engine cruise missile can be equipped with a powered high-speed fluid generator and an unpowered passive high-speed fluid generator with an air collection structure in addition to the powered high-speed fluid generator.

[0027] The fluid curvature engine flying saucer is composed of a fluid curvature engine, a flying saucer body, a control system, a landing device, etc. The fluid curvature engine flying saucer is in the shape of a flying saucer as a whole.

[0028] In a third aspect, the present invention provides a method for controlling a fluid curvature engine device, which is applied to the fluid curvature engine described in the first aspect and the fluid curvature engine device described in the second aspect, comprising the following steps:

[0029] When the fluid curvature engine needs to be activated to provide driving force, the high-speed fluid generator is turned on, and the high-speed fluid generated by the high-speed fluid generator is sprayed at a certain angle toward the multi-convex ring disc wing in the flying disc shell. The high-speed fluid sprayed into the flying disc shell can circulate in the flying disc shell and repeatedly flow through the upper convex surface of the multi-convex ring disc wing, so that the multi-convex ring disc wing is in a relatively high-speed fluid, making the aerodynamic environment of the multi-convex ring disc wing similar to that of the wing of a fixed-wing aircraft flying at high speed in the air. The viscosity of the fluid and the inertia of the high-speed fluid work together to block the atmospheric pressure and generate corresponding multiple low-pressure areas in the descending curvature area of ​​the convex surface of the multi-convex ring disc wing. The pressure difference between the upper and lower surfaces generates corresponding multiple lift areas on the multi-convex ring disc wing, thereby enabling the fluid curvature engine to generate driving force.

[0030] After the curvature engine is activated, a strong cyclone or liquid cyclone will form in the direction of its opening, similar to a tornado or vortex. The overall density and pressure of the fluid in the direction of the opening will decrease, and the resistance to moving forward in this direction will be smaller.

[0031] The driving force generated by the fluid curvature engine can be used to meet the maneuvering needs of the fluid curvature engine vehicle, such as ascent, descent, hovering, forward, backward, translation, and steering. The throttle or electric switch of the fluid curvature engine vehicle is controlled to control the flow rate and flow velocity of the fluid sprayed toward the multi-convex ring disc wing, thereby providing driving forces of different magnitudes. The size of the high-speed fluid generator nozzle and the relative angle and position with the multi-convex ring disc wing can also be adjusted according to needs to make the fluid curvature engine generate driving forces of different magnitudes. The size and number of the curvature protrusions can also be adjusted to generate driving forces of different magnitudes.

[0032] Steering force can be obtained by changing the orientation of the fluid curvature engine relative to the fluid curvature engine equipment or vehicle, or by changing the fluid flow rate at different positions of the multi-convex ring disc wing. The parts with fast flow rate have greater lift, while the parts with slow flow rate have less lift, causing the lift force of the multi-convex ring disc wing to be unbalanced, thereby generating a steering torque. Steering force can also be obtained by changing the different driving forces of each engine in the fluid curvature engine group. Conventional rudders or fluid injection methods can also be used to provide power for forward, backward, translation, steering and other movements.

[0033] Turn off the high-speed fluid generator, the flow rate of the nozzle fluid will decrease, the driving force of the curvature engine will gradually decrease, and the operating speed of the fluid curvature engine equipment will also decrease until it finally stops.

[0034] The beneficial effects of the present invention are as follows: the fluid curvature engine fully utilizes the principle that the viscosity of the fluid and the inertia of the high-speed fluid act together to block atmospheric pressure in the descending curvature region of the upper convex surface, thereby generating low-pressure areas and lift areas. This controls the high-speed fluid to circulate within the flying disc shell, repeatedly flowing through the upper convex surface of the multi-convex ring disc wing, thereby generating multiple corresponding low-pressure areas and lift areas in the descending curvature region of the upper convex surface of the multi-convex ring disc wing. This results in an extremely high lift-to-drag ratio, a high ceiling, low noise, and convenient and safe operation. Furthermore, the maximum takeoff and landing weight of the fluid curvature engine aircraft can exceed several times that of a fixed-wing aircraft of the same power and more than ten times that of a rotary-wing helicopter of the same power, making takeoff and landing easy. The fluid curvature engine aircraft has the advantages of extremely high power load, high speed, long range, high ceiling, low noise, and easy operation. In particular, it can also take off and land vertically and hover in the air. It has no special requirements for takeoff and landing sites and can take off and land on a flat piece of land, eliminating the need for a dedicated large airport.

[0035] Because this fluid curvature engine redefines the flow field in which it is located, the impact of environmental airflow is reduced and the self-controllability is greatly increased, so that fluid curvature engine vehicles can fly stably under complex airflow conditions at low altitudes, and the transition between vertical flight and level flight is smooth. It is suitable for medium and high altitude flights as well as low and ultra-low altitude flights. It can achieve flight in the full range from low altitude to high altitude, and flight in the full speed range from high speed to low speed and even hovering. It can also realize navigation, driving and flying in the full range of sea, land, air and submarine.

[0036] The fluid curvature engine vehicle is easy to use, highly safe, and has a wide range of uses. It can be used for inter-city transportation, urban aerial three-dimensional transportation, and can also be used in military, emergency, rescue, special, marginal, agricultural and other fields, forming an aerial rapid transportation network, greatly alleviating urban traffic congestion, and increasing the travel speed and efficiency by several times or even dozens of times compared to the existing plane travel mode dominated by cars and subways, significantly improving the travel rate.

[0037] The fluid curvature engine uses a small portion of the rocket engine's high-speed airflow to generate enough lift to overcome the rocket's gravity. This helps the rocket escape the atmosphere with minimal energy consumption, multiplying the payload of a comparable rocket, and significantly reducing launch costs and difficulty. Furthermore, spacecraft, space shuttles, reusable rockets, and airdropped equipment and supplies can use the fluid curvature engine to return to Earth. Using its kinetic energy and gravitational potential energy, it can achieve a precisely controlled and smooth landing at any location, eliminating the need for additional energy input and conserving energy.

[0038] After the curvature engine is started, a strong cyclone or liquid cyclone will be formed in the direction of its opening, similar to a tornado or vortex. The overall density and pressure of the fluid in the opening direction will decrease, and the resistance to moving in this direction will be smaller, which will achieve higher speeds and less resistance.

[0039] For example, the high-speed fluid generator in this fluid curvature engine vehicle is primarily powered by electricity, achieving near-zero emissions during operation. This is highly environmentally friendly and low-energy, even lower than water transportation costs. This will promote efficient and environmentally friendly transportation across aerospace, urban, intercity, and rural areas, particularly in remote areas, revolutionizing transportation and ushering in an era of comprehensive, three-dimensional transportation.

[0050] To overcome the disadvantage of low thrust-to-weight ratio of existing engines, please refer to Figures 1 to 5 In a first aspect, the present invention provides a fluid curvature engine, comprising a disc shell, a multi-convex ring disc wing, and a high-speed fluid generator, wherein the multi-convex ring disc wing is disposed on the inner cavity surface of the disc shell, or a plurality of protrusions with curvature arcs are directly disposed on the inner cavity surface of the disc shell, and the multi-convex ring disc wing is integrated with the disc shell to achieve disc fusion;

[0052] Each of the protrusions with a curvature arc is similar to a single-convex wing, and the multi-convex ring disc wing is equivalent to a combination of multiple wing sections connected in sequence in the direction of circumferential fluid flow in the manner of leading edge to trailing edge;

[0053] The high-speed fluid generated by the high-speed fluid generator is sprayed at a certain angle toward the multi-convex ring disc wing in the flying disc shell.

[0054] See also Figures 1 to 7 In a second aspect, the present invention provides a fluid curvature engine device, which uses the fluid curvature engine described in the first aspect to provide driving force, wherein the fluid curvature engine device is any one of a fluid curvature engine vehicle, a fluid curvature engine engine, a fluid curvature engine generator, a fluid curvature engine airborne equipment, a fluid curvature engine space shuttle, a fluid curvature engine spacecraft, a fluid curvature engine rocket, a fluid curvature engine cruise missile, and a fluid curvature engine loitering missile, or a combination thereof;

[0055] The fluid curvature engine of the fluid curvature engine space shuttle, fluid curvature engine spacecraft, fluid curvature engine rocket, fluid curvature engine cruise missile, and fluid curvature engine loitering missile can be configured with an unpowered passive high-speed fluid generator in addition to a powered high-speed fluid generator.

[0056] The fluid curvature engine can be installed independently on the equipment or integrated with the equipment;

[0057] The fluid curvature engine equipment is any one or a combination of fluid curvature engine vehicles, fluid curvature engine engines, fluid curvature engine generators, fluid curvature engine airborne equipment, fluid curvature engine space shuttles, fluid curvature engine spacecraft, fluid curvature engine rockets, fluid curvature engine cruise missiles, and fluid curvature engine cruise missiles.

[0058] When the fluid curvature engine needs to be activated to provide driving force, the high-speed fluid generator is turned on, and the high-speed fluid generated by the high-speed fluid generator is sprayed at a certain angle toward the multi-convex ring disc wing in the flying disc shell.

[0059] After the curvature engine is activated, a strong cyclone or liquid cyclone will form in the direction of its opening, similar to a tornado or vortex. The overall density and pressure of the fluid in the direction of the opening will decrease, and the resistance to moving forward in this direction will be smaller.

[0060] The driving force generated by the fluid curvature engine can be used to meet the maneuvering needs of the fluid curvature engine vehicle, such as ascent, descent, hovering, forward, backward, translation, and steering. The throttle or electric switch of the fluid curvature engine vehicle is controlled to control the flow rate and flow velocity of the fluid sprayed toward the multi-convex ring disc wing, thereby providing driving forces of different magnitudes.

[0062] Turn off the high-speed fluid generator, the flow rate of the nozzle fluid will decrease, the driving force of the curvature engine will gradually decrease, and the operating speed of the fluid curvature engine equipment will also decrease until it finally stops.

[0063] Example 1: Disc-shaped fan fluid curvature engine example

[0064] like Figures 1 to 2As shown, this embodiment provides a fluid curvature engine, specifically a disc-shaped fan fluid curvature engine, characterized by being primarily composed of a disc housing, a multi-convex ring disc wing, and a high-speed fluid generator. The disc housing is a disc-shaped, open semi-cavity. The multi-convex ring disc wing is disc-shaped, with multiple curvature projections on its upper surface along the circumferential fluid flow direction. Each curvature projection resembles a single-convex wing. The multi-convex ring disc wing is equivalent to a combination of multiple wing sections connected sequentially in a leading-edge-to-trailing-edge fashion along the circumferential fluid flow direction. The multi-convex ring disc wing is integrated with the disc housing, i.e., multiple curvature projections are directly integrated onto the inner surface of the disc housing, achieving disc-wing fusion. This further simplifies design and manufacturing, and improves efficiency, performance, reliability, and safety. The high-speed fluid generator is a rotor or fan, mounted above the multi-convex ring disc wing, capable of generating and outputting a circumferential high-speed airflow. When the rotor or fan is started, the circumferential high-speed air generated can circulate within the flying disc shell, repeatedly flowing through the upper convex surface of the multi-convex ring disc wing, so that the multi-convex ring disc wing is in a relatively high-speed fluid, making the aerodynamic environment of the multi-convex ring disc wing similar to that of the wing of a fixed-wing aircraft flying at high speed in the air. The viscosity of the fluid and the inertia of the high-speed fluid work together to block the atmospheric pressure and generate corresponding multiple low-pressure areas in the descending curvature area of ​​the convex surface of the multi-convex ring disc wing. The pressure difference between the upper and lower surfaces generates corresponding multiple lift areas on the multi-convex ring disc wing. In addition, a strong cyclone will form in the direction of its opening, similar to a tornado. The overall density and pressure of the fluid in the opening direction are reduced, so that its maximum lift-to-drag ratio can be several times higher than that of existing single-convex wing aircraft, reaching more than 100. At the same time, the wind resistance in this direction can also be greatly reduced.

[0065] like Figure 3 As shown, multiple disc-shaped fluid curvature engines can be combined together in a certain structural form to form a multi-disc-shaped fluid curvature engine group, which is convenient for controlling flight.

[0066] Example 2 Polygonal Ring Built-in Generator Fluid Curvature Engine Example

[0067] like Figure 4As shown, this embodiment provides a fluid curvature engine, specifically a polygonal annular built-in generator fluid curvature engine, characterized by being primarily composed of a disc shell, a multi-convex ring disc wing, and a high-speed fluid generator. The disc shell is an annular, open semi-cavity, and the multi-convex ring disc wing is annular. The upper surface of the multi-convex ring disc wing has multiple protrusions with curvatures along the circumferential fluid flow direction. Each curvature-bearing raised surface resembles a single-convex wing. The multi-convex ring disc wing is equivalent to a combination of multiple wing sections connected sequentially in a leading-to-trailing-edge fashion along the circumferential fluid flow direction. The multi-convex ring disc wing is integrated with the disc shell, i.e., multiple curvature-bearing raised surfaces are directly integrated onto the inner surface of the disc shell, achieving disc-wing fusion. This further simplifies design and manufacturing, and improves efficiency, performance, reliability, and safety. The high-speed fluid generator is an axial flow fan built into the flow channel within the disc shell, capable of generating and outputting a circumferential high-speed airflow. When the axial fan is activated, the circumferential high-speed air it generates circulates within the disc shell, repeatedly flowing through the convex surface of the multi-lobed disc wing. This places the disc wing in a relatively high-speed fluid, creating an aerodynamic environment similar to that of a fixed-wing aircraft wing in high-speed flight. The viscosity of the fluid and the inertia of the high-speed fluid combine to block atmospheric pressure, creating multiple corresponding low-pressure areas in the descending curvature regions of the convex surface of the disc wing. The pressure difference between the upper and lower surfaces generates multiple corresponding lift areas on the disc wing. Furthermore, a strong cyclone, similar to a tornado, forms in the direction of the opening. The overall density and pressure of the fluid in this direction decrease, resulting in a maximum lift-to-drag ratio several times higher than that of existing single-lobed wing aircraft, reaching over 100. Wind resistance in this direction is also significantly reduced.

[0068] like Figure 5 As shown, multiple annular fluid curvature engines of varying sizes can be assembled together to form a high-power multi-annular fluid curvature engine. Multiple annular fluid curvature engines can also be combined in a specific structural form to form a multi-annular fluid curvature engine group, facilitating flight control.

[0069] Example 3: Airborne Equipment Example of a Fluid Curvature Engine with a Gas Gathering Structure

[0070] like Figures 6 and 7As shown, this embodiment provides a fluid curvature engine airborne equipment, specifically an air-gathering structure fluid curvature engine airborne equipment, wherein the high-speed fluid generator of the fluid curvature engine is an air-gathering structure, and the air-gathering structure is a trumpet-shaped structure with a larger front and a smaller back. When necessary, the large front end opening of the air collecting structure is opened, and the air collecting structure uses the relative high-speed movement of the fluid curvature engine equipment and the fluid to press the fluid in from the large front end opening, and uses its own trumpet-mouth convergence structure or Laval tube structure to accelerate the fluid, and then sprays the high-speed fluid from the small rear end opening of the air collecting structure to the multi-convex ring disc wing in the flying disc shell at a certain angle. The high-speed fluid sprayed into the flying disc shell can circulate in the flying disc and repeatedly flow through the upper convex surface of the multi-convex ring disc wing, so that the multi-convex ring disc wing is in a relatively high-speed fluid, so that the aerodynamic environment of the multi-convex ring disc wing is similar to that of the wing of a fixed-wing aircraft flying at high speed in the air, thereby generating corresponding multiple low-pressure areas in the descending curvature area of ​​the convex surface of the multi-convex ring disc wing, and then generating corresponding multiple lift areas on the multi-convex ring disc wing, so that the airborne equipment of the fluid curvature engine of the air collecting structure generates sufficient controllable lift, ensuring that the airborne equipment of the fluid curvature engine of the air collecting structure and the materials it carries land on the ground at a low speed and steadily.

[0071] Example 4 Fluid Curvature Engine Flying Saucer Example

[0072] This embodiment provides a fluid curvature engine aircraft, specifically a fluid curvature engine flying saucer. The fluid curvature engine flying saucer is composed of a fluid curvature engine, a saucer body, a control system, and landing gear, and is shaped like a saucer. The engine of the fluid curvature engine flying saucer can be a single fluid curvature engine, a group of fluid curvature engines, or a multi-ring fluid curvature engine. The multi-ring fluid curvature engine is composed of multiple annular fluid curvature engines of varying sizes.

[0073] When the flying saucer needs to take off, the high-speed fluid generator is turned on, and the high-speed fluid generated by the high-speed fluid generator is sprayed at a certain angle toward the multi-convex ring disc wing in the flying saucer shell. The high-speed fluid sprayed into the flying saucer shell can circulate in the flying saucer shell and repeatedly flow through the upper convex surface of the multi-convex ring disc wing, so that the multi-convex ring disc wing is in a relatively high-speed fluid, making the aerodynamic environment of the multi-convex ring disc wing similar to that of the wing of a fixed-wing aircraft flying at high speed in the air. The viscosity of the fluid and the inertia of the high-speed fluid work together to block the atmospheric pressure and generate corresponding multiple low-pressure areas in the descending curvature area of ​​the convex surface of the multi-convex ring disc wing. In addition, after the curvature engine is started, a strong cyclone or liquid cyclone will be formed in the direction of its opening, similar to a tornado or vortex. The overall density and pressure of the fluid in the direction of the opening are reduced, and the pressure difference between the upper and lower surfaces generates corresponding multiple lift areas on the multi-convex ring disc wing, thereby enabling the fluid curvature engine to generate sufficiently large lift to drive the flying saucer into the air.

[0074] Controlling the fluid curvature engine saucer's throttle or electric switch controls the flow rate and velocity of the fluid sprayed onto the multi-lobed disc, thereby providing varying degrees of driving force. The fluid curvature engine can also generate varying degrees of driving force by adjusting the size of the high-speed fluid generator's nozzle and its relative angle and position to the multi-lobed disc as needed. The size and number of the curvature protrusions can also be adjusted to generate varying degrees of driving force. The fluid curvature engine saucer's control system allows it to ascend, descend, hover, advance, retreat, translate, and turn.

[0075] Steering force can be obtained by changing the orientation of the fluid curvature engine relative to the fluid curvature engine flying saucer. Alternatively, steering force can be obtained by varying the fluid flow rate at different locations on the multi-convex ring disc. The areas with high flow rate have greater lift, while areas with slow flow rate have less lift, creating an imbalance in the lift force of the multi-convex ring disc, thereby generating a steering torque. Steering force can also be obtained by varying the driving forces of the various engines in the fluid curvature engine assembly. Of course, conventional control surfaces or fluid injection methods can also be used to provide power for forward, backward, translational, and steering movements. The described fluid curvature engine flying saucer has a fast response speed, good maneuverability, and a high power load.

[0076] After the curvature engine is started, a strong cyclone will form in the direction of its opening, similar to a tornado. The overall density and pressure of the fluid in the direction of the opening will decrease, and the resistance to moving in this direction will be smaller.

[0077] After arriving above the destination, the high-speed fluid generator is gradually turned down, the flow rate of the nozzle fluid gradually decreases, the driving force of the curvature engine also gradually decreases, and the flying saucer continues to descend until it lands on the ground and finally stops.

[0078] Example 5 Fluid Curvature Engine Rocket Example

[0079] This embodiment provides a fluid curvature engine rocket. A fluid curvature engine is installed at the bottom of the rocket, and a small amount of high-speed airflow generated by the rocket engine is introduced into the fluid curvature engine through a duct to generate lift to overcome the rocket's own weight, which can easily help the rocket fly out of the atmosphere with low consumption. After installing the fluid curvature engine, the payload of rockets of the same specifications can be increased several times, greatly reducing the cost and difficulty of launch. In addition, when the rocket returns through the atmosphere after putting the payload into the predetermined orbit, the gas-gathering structure fluid curvature engine effectively converts the rocket's kinetic energy and gravitational potential energy, which is sufficient for it to perform controllable aerodynamic flight in the atmosphere. Without the need for a parachute or rocket engine reverse thrust, it can achieve a controllable, precise and smooth landing at any location.

[0080] After the curvature engine is started, a strong cyclone will be formed in the direction of its opening, similar to a tornado. The overall density and pressure of the fluid in the opening direction will decrease, and the resistance to moving in this direction will be smaller. The fluid curvature engine rocket will be able to achieve higher speeds and less resistance.

Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.

The high-speed fluid sprayed into the flying disc shell can circulate in the flying disc shell and repeatedly flow through the upper convex surface of the multi-convex ring disc wing, so that the multi-convex ring disc wing is in a relatively high-speed fluid, making the aerodynamic environment of the multi-convex ring disc wing similar to that of the wing of a fixed-wing aircraft flying at high speed in the air. The viscosity of the fluid and the inertia of the high-speed fluid work together to block the atmospheric pressure and generate corresponding multiple low-pressure areas in the descending curvature area of ​​the convex surface of the multi-convex ring disc wing. The pressure difference between the upper and lower surfaces generates corresponding multiple lift areas on the multi-convex ring disc wing, thereby enabling the fluid curvature engine to generate driving force. After the fluid curvature engine is activated, a strong cyclone or liquid cyclone will be formed in the direction of its opening, similar to a tornado or vortex.

The size of the high-speed fluid generator nozzle and its relative angle and position with the multi-convex ring disc wing can be adjusted as needed to enable the fluid curvature engine to generate driving forces of varying magnitudes. Alternatively, the size and number of the curvature protrusions can be adjusted to generate driving forces of varying magnitudes. Steering force is obtained by changing the orientation of the fluid curvature engine relative to the fluid curvature engine equipment, or by changing the fluid flow rate at different positions of the multi-convex ring disc wing. The parts with fast flow rate have greater lift, while the parts with slow flow rate have less lift, causing the lift force of the multi-convex ring disc wing to be unbalanced, thereby generating a steering torque; or by changing the different driving forces of each engine in the fluid curvature engine group to obtain steering force; or by using conventional rudders or fluid injection methods to provide power for forward, backward, translation, and steering movements; Turn off the high-speed fluid generator, the flow rate of the nozzle fluid will decrease, the driving force of the curvature engine will gradually decrease, and the operating speed of the fluid curvature engine equipment will also decrease until it finally stops.
