Description

Technical Field

[0001] The present invention relates to an aircraft such as a new type of drone that can perform vertical takeoff and landing and horizontal flight at high speed.

Background Art

[0002] A normal airplane taxis on a runway until it reaches a speed at which it can take off. Conversely, when landing, it also taxis from the moment of landing until it stops, so a runway is required. Generally, a distance of about 1.5 km to 3 km is necessary. Therefore, a VTOL (Vertical Takeoff and Landing Aircraft) is required. As this type of aircraft, helicopters, Ospreys, drones, etc. are known. A helicopter uses one propeller for hovering, ascending, descending, and horizontal flight, respectively, as shown in FIG. 1. In FIG. 1, 1 is the airframe, 3 is the tail rotor, and 32 is the motor for propeller rotation.

[0003] Since helicopters have a low horizontal speed, the Osprey (FIG. 2), which has a high horizontal speed, was developed. The Osprey was invented by the inventor in 1953. The inventor taught it to Mr. Lawrence Bell, the CEO of Bell Aircraft Corporation, and Bell Aircraft Corporation has finally put it into practical use in recent years. Propellers with tilt control capabilities are provided at both ends of the main wing, and by controlling the tilt angle of these propellers, hovering and horizontal flight are possible. To perform ascending and straight-ahead operations, the tilt angle of the propellers is changed from 0 degrees to 90 degrees. However, many accidents occur during the conversion of the rotors from horizontal to vertical. In FIG. 2, 1 is the airframe, 34 is the Osprey ascending / descending / forward propeller, 4 is the horizontal tail, 5 is the Osprey engine rotation shaft, and 33 is the Osprey propeller engine, which has finally become popular in recent years. FIG. 3 shows a known drone, which was also invented by the inventor in 1940 and has finally become popular in recent years. In FIG. 3, 6 is the drone propeller, 7 is the drone ascending / descending motor, 8 is the drone propeller guide, and 9 is the receiving device / camera, etc.

Summary of the Invention

Problems to be Solved by the Invention

[0004] As described above, an airplane cannot take off or land at a place without a runway. Ordinary airplanes have the drawback of not having vertical takeoff / landing or hovering functions. To solve such problems, a flying object with vertical takeoff / landing and hovering functions has been considered. A helicopter is a flying object with vertical takeoff / landing and hovering functions and has been active in saving lives in shipwreck accidents, mountain distress accidents, etc. However, since its horizontal flight speed is slow, its flight endurance is also short, and the amount of load it can carry is small, a flying object to replace the helicopter is required. In the case of an Osprey-type airplane, when taking off or landing vertically, the wind from the propeller hits the wings, resulting in aerodynamic inefficiency. Also, drones such as shown in Figure 3 are known, but drones have a slow horizontal flight speed and cannot fly long distances. They can be overturned by crosswinds and are not all-weather types. Although Amazon and others have plans, they are not suitable for cargo delivery or rapid transportation.

Means for Solving the Problems

[0005] The present invention for solving the above problems is configured by providing a propeller for vertical ascent / descent and forward movement and a stabilizer for horizontal flight. This is a means different from an autogyro that cannot perform vertical ascent / descent.

Effects of the Invention

[0006] According to the present invention, it has a high horizontal speed, can cover long distances with little energy, has a large load capacity, is all-weather, has a safe and stable vertical takeoff / landing and hovering function, has no wing force loss caused by the propeller wind hitting the wings during takeoff and ascent, does not require a tilt rotor, has a simple control structure, has no accidents, is easy to manufacture and low-cost, and can surely deliver mail-order commodity transportation at high speed over long distances with high energy efficiency. It can provide a vertical takeoff / landing type high-speed long-distance safe airplane, which is an epoch-making invention that saves time and produces significant effects in the industry.

Mode for Carrying Out the Invention

[0008] The present invention is a new invented aircraft made in view of such problems, and is provided with a propeller for ascending and descending, a propeller for forward movement, and wings for horizontal flight that rotate or do not rotate, and can not only vertically take off and land and hover, but also has a high horizontal flight speed, low energy loss, can fly long distances, and is an all-weather type that can fly stably even in bad weather. The purpose is to provide a new vertical takeoff and landing type aircraft (new VTOL). It should be noted that the present invention is based on an idea different from that of a conventional drone, helicopter, Osprey, or autogyro.

[0009] Figure 4 is a plan view of the first embodiment of the invented aircraft of the present invention. In the figure, 13 is a horizontal stabilizer, 14 is a vertical stabilizer, and 10 is a propeller for forward movement. 12 is a main wing for horizontal flight and is supported by the ascending propeller guard 8 and the main wing girder 15. 6 is a propeller for ascending / descending and hovering. These main wings 12 and main wing spars 15 are provided in a pair on the left and right of the propeller guard 8. 14 is a horizontal tail provided at the rear of the propeller guard 8, and 13 is a vertical tail for steering supported by the propeller guard 8. 7 is a motor for rotating the hovering propeller 6. 9 is a camera for photography, an electronic circuit, a battery, etc. The aircraft of the present invention is provided with main wings 12, a tail 13, and a forward propeller 10 without interfering with the ascending propeller, and can increase the horizontal flight speed. This is the first embodiment of the present invention that uses the propeller guard 8 to structurally support and share the forward propeller 10, the rotating motor 11, the main wings 12, and the tails 13, 14.

[0010] Figure 5 is a plan view of a tailless drone according to the second embodiment of the present invention. It is a plan view of the second embodiment of the present invention provided with a wing spar 15, main wings 20, elevators 16, vertical arms 17 in the wing tip vertical direction, a push propeller 18 at the rear, and a drive motor 19. The gist of the present invention is as described with reference to Figure 4.

[0011] Figure 6 shows a forward-tail type embodiment of the present invention, which includes a forward-tail spar 22 supported by a propeller guard 13, a forward-tail 21 supported by a propeller guard 8, a propeller motor 11, a pull propeller 10, a main wing spar 35 supported by a propeller card 8, a main wing 31, a drive motor 19 of a push-type propeller 18 supported by a propeller guard 8, and a vertical tail 30 at the main wing tip.

[0012] Figure 7 shows a fourth embodiment of the present invention, which is an aircraft in a tandem type in which two main wings 36 and 37 also serve as propeller guards without providing a propeller guard 13, and the front wing 36 and the rear wing 37 are in a tandem type of the same size. That is, a propeller 6 and a motor 7 for ascending and descending are provided between the two wings, and the main wings 36 and 37 guard the rotation of the propeller 6. 38 is a support spar for the ascending and descending propeller motor 7 provided outside the wing. Of course, the number of propellers may increase or decrease and still be included in the present invention.

[0013] Figure 8 shows the fifth embodiment of the present invention, in which the rotational trajectories 39 of four upper and lower propellers are all inscribed, and four main wings 24, a tail fin 28, and a tail wing 29 are used in place of a propeller guard without providing a propeller guard. 40 is a beam connecting four propeller motors 7.

[0014] Figure 9 shows the sixth embodiment of the present invention, in which a propeller motor 7 and main wings 42 are attached to a square frame 41. This is the same as Figure 8, but in this embodiment, the four main wings are solar panels 42. It can fly permanently using solar energy and can send energy to the ground by microwave.

[0015] Figure 10 shows the seventh embodiment of the present invention, in which upper and lower propellers 6 and motors 7 are provided outside the main wings 43 and 44, and the main wing structure is simplified. To explain the operation of the airplane configured as shown in Figures 4, 5, 6, 7, 8, 9, and 10, it is as follows. In this case, first, when the operator turns on switch 1 (not shown) with a remote control, the ascending motor 7 and ascending propeller 6 of the drone start rotating wirelessly, and the aircraft ascends to a predetermined altitude. Next, when the operator turns on remote control switch 2 (not shown), the forward propeller 7 and push propeller 18 are rotated by the rotational force of motors 11 and 19. The aircraft starts moving forward, and the buoyancy is shared by the main wing 12 and tail wing 13 in Figure 4, 20 in Figure 5, 21 and 31 in Figure 6, 36 and 37 in Figure 7, 24 and 28 in Figure 8, 42 in Figure 9, and 43 and 44 in Figure 10. During this time, the ascending propeller 6 and motor 9 rotate idly. And it reaches the destination faster than a known drone, so it is superior to a known drone for product sales and remote area photography. Next, the operation during landing will be described. At the time of landing, the operator increases the rotation of all the upper and lower propellers 6 and stops the rotation of the forward propeller 10. Touch down while controlling the rotation of the upper and lower propellers 6 in this state. According to the present invention, at the time of landing, there is no need for a circuit or command for controlling the tilt angle of the propeller (refer to the control in FIG. 1) or changing the rotation speed of a plurality of horizontal propellers of the drone, the structure becomes simple, the cost is reduced, the operation is simplified, and the landing operation can be performed safely and reliably. Moreover, since a fixed wing is used for horizontal flight, high-speed flight can be achieved. In addition, since the wing can be also used as a propeller guard, the structure is simple and the weight can be reduced.

[0016] FIG. 12 is a plan view of the ninth embodiment of the twin-engine present invention. Horizontal flight is equipped with two propellers 10, capable of high-speed running and long-distance movement. Four propellers 6 are provided for vertical ascent and descent. 21 is a girder provided between the engines 11, 53 is a girder connecting the engine 11 and the mechanism part 54, and 55 is a girder connecting the mechanism parts 54. As shown in FIG. 12, this invention can also be used as an aircraft for carrying a large number of people.

[0017] The above is about the drone. FIG. 11 shows a side view of the actual machine for people to ride in the eighth embodiment of the present invention, with a forward engine 46, the same propeller 47, a fuselage 1 at the center of gravity position, and a combined ascent / descent engine 25 and a rotor 48 provided. There are a vertical tail 51, a horizontal tail 50, and a cockpit 26. The case where a jet engine or a rocket engine 27 is provided at the rear instead of the forward propeller 47 and the engine 46 is also included in the present invention. Also, the case where the ascent / descent rotor 48 and its engine 32 are provided at the wing tip 8 is of course included in the present invention. Just in case, there is something called an autogyro, which has no ascent / descent engine and is completely different from the present invention.

[0018] Up to the ninth embodiment, the wing is fixed and a separate forward propeller is provided. Up to the ninth embodiment, a wing is not arranged in the propeller wake part so that the wake of the propeller for ascent and descent is not disturbed. And the wing is fixed. Also, the forward propeller is provided separately from the propeller for ascent and descent.

[0019] The present invention is applicable not only to drones but also to actual machines. In that case, the propellers are rotated by an engine. Also, the present invention includes cases where jet engines or rockets are used instead of propellers.

Industrial Applicability

[0020] The present invention is a new type of aircraft that is safer and has a higher horizontal speed compared to other vertical takeoff and landing aircraft such as known drones and known tiltrotors like ospreys and helicopters. Current drones are not suitable for high-speed transportation because they are slow for long-distance goods transportation such as online sales and logistics, cannot fly long distances, and consume a lot of energy. However, when the present invention is applied to a drone, goods can be transported at high speed and long-distance photography becomes possible. Also, when the present invention is applied to an aircraft carrying people, it can be active in rapid mountain rescue, shipwreck rescue, etc. in distant places, so there is great industrial applicability. In addition, the aircraft of the present invention does not require pitch control compared to a helicopter, so the rudder is simple and low-cost. Moreover, it has a high horizontal speed, a long flight range, and there are no accidents due to the tilt of an osprey, so it is safe and its range of use expands. Also, if the size of the aircraft is increased, a large number of people can be carried, and it can also take off and land on an island without an airport, compensating for the inconvenience of transportation for islanders, and has extremely great applicability in terms of defense and industry. Also, if the aircraft of the present invention is flown near the stratosphere, converts the solar energy received by the wings into microwaves and sends them to the ground for use as electrical energy on the ground, it can supply precious energy to resource-poor Japan and can also replace reconnaissance satellites. It has extremely great applicability in terms of defense and industry.
