Description

The present invention relates to a new type of aircraft such as a drone that can take off and land vertically and fly horizontally at high speed.

A normal plane rolls down a runway until it reaches a speed that allows it to take off. Conversely, when landing, a runway is required because the aircraft runs from landing to stopping. A general distance of about 1.5 km to 3 km is required. Therefore, a VTOL (vertical take-off and landing aircraft) is required.
Helicopters, Ospreys, drones, and the like are known as this type of aircraft. A helicopter uses one propeller for each of hovering, ascent, descent and level flight, as shown in FIG. In FIG. 1, 1 is the fuselage, 3 is the tail rotor, and 32 is the propeller rotating motor.

Helicopters have a slow horizontal speed, so the Osprey (Fig. 2) was developed with a fast horizontal speed. The Osprey was invented by the present inventor in 1953, and was taught to Mr. Lawrence Bell, the CEO of Bell Aircraft Corporation.
It has propellers that can be tilted at both ends of the main wing, and by controlling the tilt angle of this propeller, hovering functions and horizontal flight are possible. The propeller tilt angle is varied from 0 degrees to 90 degrees for climbing and straightening operations. However, many accidents occur when converting the rotor from horizontal to vertical.
In FIG. 2, 1 is the fuselage, 34 is the Osprey ascending/descending/advancing propeller, 4 is the horizontal stabilizer, 5 is the rotation shaft for the Osprey engine, and 33 is the engine for the Osprey propeller, which has finally become popular in recent years.
FIG. 3 shows a known drone, which was also invented by the inventor in 1940, but has only recently become popular. In FIG. 3, 6 is a drone propeller, 7 is a motor for raising and lowering the drone, 8 is a drone propeller guide, and 9 is a receiving device, a camera, and the like.

As mentioned earlier, planes cannot take off and land where there is no runway. Ordinary airplanes have the drawback of not having vertical take-off and landing and hovering functions. In order to solve such problems, a flying object with vertical take-off and landing and hovering functions was conceived. Helicopters are flying objects that have vertical takeoff and landing and hovering functions, and are used to save lives in sea accidents and mountain distress accidents. Since the amount of cargo to be carried is also small, there is a demand for flying vehicles that can replace helicopters.
In the case of the Osprey-type aircraft, propeller wind beats against the wings during vertical take-off and landing, resulting in aerodynamic inefficiency.
In addition, a drone as shown in Fig. 3 is well known, but the horizontal flight speed of the drone is slow and it cannot fly long distances. Not suitable as

The present invention for solving the above-described problems is configured by providing a forward propeller for vertical ascent and descent and a stabilizing blade for horizontal flight. This is a means different from the autogyro, which cannot move up and down vertically.

According to the present invention, the horizontal speed is high, the load capacity is large with small energy for long distances, it is all-weather type, it has safe and stable vertical takeoff and landing and hovering function, and the wing power that the propeller wind hits the wing at the time of takeoff and climb. A vertical take-off and landing high-speed, long-distance, high-speed, long-distance, energy-efficient, high-speed, long-distance transport of mail-order products that is easy to manufacture, low-cost, and has no losses and does not require a tilt rotor, simplifies the control structure, and eliminates accidents. It is an epoch-making invention that can provide a safe aircraft and produce industrial time-saving and major depth effects.

FIG. 10 shows a seventh embodiment of the present invention, in which a vertical propeller 6 and a motor 7 are provided outside the main wings 43 and 44 to simplify the structure of the main wings.
The operation of the airplane constructed as shown in FIGS. 4, 5, 6, 7, 8, 9 and 10 will now be described.
In this case, when the operator first turns on the switch 1 (not shown) with the remote controller, 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 the remote control switch 2 (not shown), the rotational force of the motors 11 and 19 causes the forward propeller 7 and the push propeller 18 to rotate.
The fuselage started to move forward, and the buoyancy was the main wing 12 and the tail wing 13 in Fig. 4. 10 are shared by 43 and 44, and the ascending propeller 6 and the motor 9 are idly rotated during this time. In addition, it reaches the destination faster than the known drone, so it is superior to the known drone for product sales and remote shooting.
Next, the operation during landing will be described. At the time of landing, the operator increases the rotation of all the vertical propellers 6 and stops the rotation of the forward propeller 10. - 特許庁In this state, the robot lands while controlling the rotation of the vertical propeller 6 .
According to the present invention, the propeller tilt angle control (see the control in FIG. 1) and the circuit and command for changing the rotation speed of the multiple horizontal propellers of the drone are not required at the time of landing. is simplified, and the landing operation can be performed safely and reliably. Not only that, the horizontal version uses fixed wings, so it can fly at high speed. In addition, the blade can be used as a propeller guard, so the structure is simple and the weight can be reduced.
