Description

The present invention relates to a new type of drone or other aircraft capable of vertical takeoff and landing and level flight at high speed.

A normal plane glides on the runway until it is fast enough to take off. Also, when landing on the contrary, a runway is required because it slides from landing to stopping. The general distance needs to be about 1.5km to 3km. Therefore, VTOL (vertical takeoff and landing aircraft) is required.
Helicopters, Ospreys, drones, etc. are known as this type of airplane. As shown in FIG. 1, the helicopter uses one propeller for hovering, ascending, descending, and level flight. In FIG. 1, 1 is an airframe, 3 is a tail rotor, and 32 is a propeller rotation motor.

Since the helicopter has a slow horizontal velocity, an Osprey with a high horizontal velocity (Fig. 2) was developed. The Osprey was invented by the present inventor in 1953, which was taught to CEO Lawrence Bell of Bell Aircraft, and was finally put into practical use by Bell Aircraft in recent years.
It has propellers that can control tilt at both ends of the main wing, and by controlling the tilt angle of this propeller, hovering function and level flight are possible. The tilt angle of the propeller is changed from 0 degrees to 90 degrees in order to perform ascending and straight movements. However, many accidents occur when converting the rotor to horizontal and vertical.
In FIG. 2, 1 is an airframe, 34 is an Osprey ascending / descending / advancing propeller, 4 is a horizontal stabilizer, 5 is a rotating shaft for an Osprey engine, and 33 is an engine for an Osprey propeller, but it has finally become popular in recent years.
FIG. 3 is a known drone, which was also invented by the present inventor in 1940, but has finally become popular in recent years. In FIG. 3, 6 is a drone propeller, 7 is a drone raising / lowering motor, 8 is a drone propeller guide, and 9 is a receiving device / camera and the like.

As mentioned above, airplanes cannot take off or land in places where there is no runway. Normal airplanes have the drawback of not having vertical takeoff and landing and hovering functions. In order to solve such a problem, an air vehicle having a vertical takeoff and landing function and a hovering function was considered. A helicopter is an aircraft that has vertical takeoff and landing and hovering functions, and is active in saving lives in marine accidents and mountain distress accidents, but its horizontal flight speed is slow and its cruising range is short. Since the load capacity is small, there is a demand for an air vehicle that can replace the helicopter.
In the case of Osprey-type airplanes, the wind of the propeller hits the wings during vertical takeoff and landing, which is aerodynamically inefficient.
In addition, although drones as shown in Fig. 3 are known, drones have slow horizontal flight speeds and cannot fly long distances, and they are not all-weather type or overturned by crosswinds. Not suitable for.

The present invention that solves the above-mentioned problems is configured by providing a propeller for advancing vertically ascending and descending and a stabilizing wing for level flight. This is a different method 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 at a long distance with a small energy, it is an all-weather type, it has a safe and stable vertical takeoff and landing and hovering function, and the wing force that the propeller wind hits the wing when taking off and climbing. No loss, no tilt rotor, simple control structure, no accidents, easy to manufacture, low cost, vertical takeoff and landing type high speed long distance that can reliably deliver mail order products with high energy efficiency, high speed and long distance. It is an epoch-making invention that can provide a safe aircraft, which saves industrial time and produces a main profound effect.
