Description

Technical Field

[0001] The invention belongs to the technical field of disc-shaped aircraft, and in particular relates to a disc-shaped aircraft and a use method thereof. Background Art

[0002] As an advanced aircraft, the disc-shaped aircraft is usually designed with very high flight performance, such as high-speed flight, vertical take-off and landing, strong maneuverability, etc. The disc-shaped aircraft is an unconventional aircraft with no tail and no rudder, in which the fuselage is the wing and the wing is also the fuselage. Its control method adopts a composite control method that combines variable mass moment control and thrust vector control.

[0003] The disc-shaped aircraft adopts a wing-body fusion aerodynamic layout. Like the Blend-Wing-Body (or flying wing), it is highly integrated and its wetted area is much smaller than that of conventional aircraft of the same size. The wing-body fusion design avoids the additional resistance caused by interference between the fuselage and the wings.

[0004] The disc-shaped aircraft is not exactly the same as the flying wing. The outer wings of the disc-shaped aircraft only account for 12.2% of the total area of ​​the aircraft. The central disc body is the main lift surface of the entire aircraft. The aspect ratio of the entire aircraft is 2.3, which is much smaller than the flying wing (about 10). Compared with the flying wing, the disc-shaped aircraft has a more compact appearance and a thicker disc body, which can improve the structural strength and rigidity and provide sufficient cargo space.

[0005] The disc-shaped aircraft is a new type of rotorcraft. It can be used for civilian purposes and to meet national defense needs, as well as for the development and utilization of space resources, space operations and experiments. Compared with other rotorcraft, the disc-shaped aircraft can share batteries and control circuit boards, has a more compact structure, can generate greater lift, and can balance the torque of the aircraft through anti-torque action, without the need for special anti-torque propellers.

[0006] Some invention patents in the field of disc-shaped aircraft technology have been disclosed in the prior art. Among them, the invention patent with application number CN202310639940.4 discloses a disc-shaped aircraft, which adopts a dual-rotor brushless motor driven by a coaxial differential bearing as the main power transmission method, and the lifting and lowering and forward and backward movement of the aircraft are controlled by the lifting control wings and the front and rear control wings; it can effectively reduce the space occupied by the transmission structure and reduce the weight of the transmission structure, so as to effectively increase the load.

[0007] The invention patent with application number CN202311401186.7 discloses a disc-shaped ducted aircraft driven by electromagnetic force. Through the unique design of arranging an electromagnetic coil group on the outside of the external rotating fuselage and fixing the tip and root of the blade, it has higher energy utilization efficiency, better aerodynamic efficiency, greater structural strength and simpler structure, so that the aircraft has a higher cruising speed and longer cruising time at the same structural weight.

[0008] Both of the above prior arts have the following disadvantages:

[0009] During the use of the disc-shaped aircraft, power failure may occur. Since the above two existing technologies lack a buffer mechanism, the aircraft that loses power will fall rapidly from a high altitude, which may cause serious damage to the aircraft's outer shell and internal structure. When the disc-shaped aircraft is in use and a power failure occurs and it falls, if there is a lake or river below, water may enter the interior of the aircraft due to the lack of a mechanism to seal the aircraft, causing possible electrical short circuits, damage to internal components or other failures.

[0010] Based on this, the present invention designs a disc-shaped aircraft and a method of using the same to solve the above problems. Summary of the invention

[0020] As a further description of the above technical solution:

[0021] The bottom end of the sealing cover is connected and fixed with an electric push rod, and the other end of the electric push rod is connected and fixed with the inner wall of the outer shell of the disc-shaped aircraft.

When the sealing cover moves down, the outer end of the contact rod will abut against the inner wall of the saucer-shaped aircraft shell, causing the contact rod to move up, thereby driving the pumping and pressure plug to move up in the inflation seat, and injecting the air in the inflation seat into the sealing elastic ring through the vent pipe.

[0030] A method for using a disc-shaped aircraft comprises the following steps:

[0031] S1. When the disc-shaped aircraft is used above a water source and a power failure occurs, the electric push rod is used to drive the sealing cover to move downward and retract, so that the sealing cover seals the upper opening of the outer shell of the disc-shaped aircraft. At the same time, when the sealing cover moves downward, the outer end of the contact rod abuts against the inner wall of the outer shell of the disc-shaped aircraft, so that the contact rod moves upward, thereby driving the pressure pumping plug to move upward in the inflation seat, and injecting the air in the inflation seat into the sealing elastic ring through the ventilation pipe, so that the volume of the sealing elastic ring increases, so that the outer wall of the sealing elastic ring is closely attached to the upper opening of the outer shell of the disc-shaped aircraft, and further sealing is performed;

[0032] S2. When the sealing cover moves downward, the connected rack will be driven downward, so that the rack can drive the transmission wheel to rotate, so that the transmission wheel drives the worm to rotate, so that the worm drives the worm wheel to rotate, so that the worm wheel drives the connected universal joint to rotate, so that the ball head rod connected to the other end of the universal joint rotates, and at this time the ball head rod slides in the limit groove, thereby driving the moving plate to move downward;

[0033] S3. When the moving plate moves downward, it drives the rotating seat to move downward. At this time, under the action of the fixed guide head, the rotating seat with the guide groove is rotated, so that the sealing plate can cover the opening on the grid frame, and then the opening of the grid frame is sealed to prevent water from entering the inside of the disc-shaped aircraft when the disc-shaped aircraft falls into the water;

[0034] S4. At the same time, in order to reduce the falling speed, the motor is used to drive the connected placement seat to rotate, so that the opening of the placement seat rotates upward to expose the floating airbag. Then, when the placement seat rotates, it will drive the air pipe to rotate, so that the driving wheel connected to the air pipe drives the driven wheel to rotate, and the driven wheel drives the connected valve core to rotate, so that the high-pressure hydrogen in the inflation chamber can enter through the air inlet pipe, and be injected into the air pipe through the air outlet pipe, and then injected into the floating airbag through the connecting hose, so that the floating airbag is inflated and bulged, which cushions the falling disc-shaped aircraft and reduces the impact.

[0035] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0036] 1. In the present invention, during the use of the disc-shaped aircraft, when a power failure occurs and the aircraft falls rapidly, a floating airbag is provided. Under the action of the air guide mechanism, high-pressure hydrogen can be filled into the floating airbag to absorb the impact force during the falling process, reduce the impact force of the aircraft when it contacts the ground, and help protect the structure of the aircraft, especially key components, such as engines and airborne systems, and reduce damage caused by falling.

[0037] 2. In the present invention, during the use of the disc-shaped aircraft, when a power failure occurs and the aircraft falls rapidly, the sealing cover is used to seal the opening on the upper side of the disc-shaped aircraft, and at the same time, the transmission mechanism is driven, so that the transmission structure drives the sealing mechanism to seal the opening on the lower side of the disc-shaped aircraft, thereby preventing water from entering the interior of the disc-shaped aircraft when the disc-shaped aircraft falls into the water, ensuring that the internal equipment of the aircraft remains dry and operates normally, and preventing any functional failure or impact caused by water entering the aircraft.

[0038] 3. In the present invention, by providing an elastic ring, the inflated elastic ring can better enhance the sealing effect while the sealing cover is sealed, preventing water from entering the interior of the aircraft. At the same time, the floating airbag can not only play a buffering role, but also make the disc-shaped aircraft float on the water surface. The floating aircraft can be more easily discovered and approached, making it easier to salvage. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] A method for using a disc-shaped aircraft comprises the following steps:

[0061] S1. When the disc-shaped aircraft is used above a water source and a power failure occurs, the electric push rod 601 is used to drive the sealing cover 6 to move downward and retract, so that the sealing cover 6 seals the upper opening of the disc-shaped aircraft shell 1. At the same time, when the sealing cover 6 moves downward, the outer end of the contact rod 1004 abuts against the inner wall of the disc-shaped aircraft shell 1, so that the contact rod 1004 moves upward, thereby driving the pressure pumping plug 1002 to move upward in the inflation seat 1001, and injecting the air in the inflation seat 1001 into the sealing elastic ring 10 through the ventilation pipe 1005, so that the volume of the sealing elastic ring 10 increases, so that the outer wall of the sealing elastic ring 10 is closely attached to the upper opening of the disc-shaped aircraft shell 1, and further sealing is performed;

[0062] S2. When the sealing cover 6 moves downward, the connected rack 604 moves downward, so that the rack 604 can drive the transmission wheel 502 to rotate, so that the transmission wheel 502 drives the worm 501 to rotate, so that the worm 501 drives the worm wheel 503 to rotate, so that the worm wheel 503 drives the connected universal joint 504 to rotate, so that the ball head rod 505 connected to the other end of the universal joint 504 rotates, and at this time the ball head rod 505 slides in the limiting groove 406, thereby driving the movable plate 405 to move downward;

[0063] S3, when the moving plate 405 moves downward, it will drive the rotating seat 401 to move downward. At this time, under the action of the fixed guide head 404, the rotating seat 401 with the guide groove 403 will rotate, so that the sealing plate 402 can cover the opening on the grid frame 3, and then the opening of the grid frame 3 is sealed, so as to prevent water from entering the inside of the disc-shaped aircraft when the disc-shaped aircraft falls into the water;

[0064] S4. At the same time, in order to reduce the falling speed, the motor 801 is used to drive the connected placement seat 8 to rotate, so that the opening of the placement seat 8 rotates upward, so that the floating airbag 9 is exposed, and then when the placement seat 8 rotates, it will drive the air guide tube 902 to rotate, so that the driving wheel 903 connected to the air guide tube 902 drives the driven wheel 703 to rotate, so that the driven wheel 703 drives the connected valve core 702 to rotate, so that the high-pressure hydrogen in the inflation chamber 602 can enter through the air inlet pipe 704, and be injected into the air guide pipe 902 through the air outlet pipe 705, and then injected into the floating airbag 9 through the connecting hose 901, so that the floating airbag 9 is inflated and bulged, which cushions the falling disc-shaped aircraft and reduces the impact.

[0065] Working principle, when in use: when the disc-shaped aircraft is in use above a water source, when a power failure occurs, the electric push rod 601 is used to drive the sealing cover 6 to move down and retract, so that the sealing cover 6 seals the upper opening of the disc-shaped aircraft shell 1. At the same time, when the sealing cover 6 moves down, the outer end of the contact rod 1004 will abut against the inner wall of the disc-shaped aircraft shell 1, so that the contact rod 1004 moves up, thereby driving the pressure pumping plug 1002 to move up in the inflation seat 1001, and injecting the air in the inflation seat 1001 into the sealing elastic ring 10 through the ventilation pipe 1005, so that the volume of the sealing elastic ring 10 increases, so that the outer wall of the sealing elastic ring 10 is closely attached to the upper opening of the disc-shaped aircraft shell 1, and further sealing is performed;

[0066] At the same time, when the sealing cover 6 moves downward, the connected rack 604 will be driven to move downward, so that the rack 604 can drive the transmission wheel 502 to rotate, so that the transmission wheel 502 drives the worm 501 to rotate, so that the worm 501 drives the worm wheel 503 to rotate, so that the worm wheel 503 drives the connected universal joint 504 to rotate, so that the ball head rod 505 connected to the other end of the universal joint 504 rotates, and at this time the ball head rod 505 slides in the limiting groove 406, thereby driving the moving plate 405 to move downward;

[0067] When the moving plate 405 moves downward, the rotating seat 401 will be driven to move downward. At this time, under the action of the fixed guide head 404, the rotating seat 401 with the guide groove 403 will rotate, so that the sealing plate 402 can cover the opening on the grid frame 3, and then the opening of the grid frame 3 is sealed, so as to prevent water from entering the inside of the disc-shaped aircraft when the disc-shaped aircraft falls into the water;

[0068] At the same time, in order to reduce the falling speed, the motor 801 is used to drive the connected placement seat 8 to rotate, so that the opening of the placement seat 8 rotates upward, so that the floating airbag 9 is exposed, and then when the placement seat 8 rotates, it will drive the air guide tube 902 to rotate, so that the driving wheel 903 connected to the air guide tube 902 drives the driven wheel 703 to rotate, so that the driven wheel 703 drives the connected valve core 702 to rotate, so that the high-pressure hydrogen in the inflation chamber 602 can enter through the air inlet pipe 704, and be injected into the air guide pipe 902 through the air outlet pipe 705, and then injected into the floating airbag 9 through the connecting hose 901, so that the floating airbag 9 is inflated and bulged, which cushions the falling disc-shaped aircraft and reduces the impact.

When the disc-shaped aircraft is used above a water source and a power failure occurs, the electric push rod (601) is used to drive the sealing cover (6) to move downward and retract, so that the sealing cover (6) seals the upper opening of the outer shell (1) of the disc-shaped aircraft. At the same time, when the sealing cover (6) moves downward, the outer end of the contact rod (1004) abuts against the inner wall of the outer shell (1) of the disc-shaped aircraft, so that the contact rod (1004) moves upward, thereby driving the pressure pumping plug (1002) to move upward in the inflation seat (1001), and injecting the air in the inflation seat (1001) into the sealing elastic ring (10) through the ventilation pipe (1005), so that the volume of the sealing elastic ring (10) increases, so that the outer wall of the sealing elastic ring (10) is closely attached to the upper opening of the outer shell (1) of the disc-shaped aircraft, and further sealing is performed; S2. When the sealing cover (6) moves downward, the connected rack (604) is driven downward, so that the rack (604) can drive the transmission wheel (502) to rotate, so that the transmission wheel (502) drives the worm (501) to rotate, so that the worm (501) drives the worm wheel (503) to rotate, so that the worm wheel (503) drives the connected universal joint (504) to rotate, so that the ball head rod (505) connected to the other end of the universal joint (504) rotates, and at this time the ball head rod (505) slides in the limiting groove (406), thereby driving the movable plate (405) to move downward; S3, when the movable plate (405) moves downward, it will drive the rotating seat (401) to move downward. At this time, under the action of the fixed guide head (404), the rotating seat (401) with the guide groove (403) will rotate, so that the sealing plate (402) can cover the opening on the grid frame (3), and then the opening of the grid frame (3) is sealed, so as to prevent water from entering the inside of the disc-shaped aircraft when the disc-shaped aircraft falls into the water; S4.
