Description

[Detailed description of the invention] (b) Industrial application field This invention relates to improvements in helicopters.

(b) Conventional technology The current mainstream of helicopters has a single rotor blade, which is rotated mechanically, and the elevation angle is adjusted as it rotates to change the lift force. Lift and horizontal propulsive force are obtained by changing the direction from vertically upward to diagonally upward, and the recoil caused by mechanically driving the rotor allows the aircraft to move in the opposite direction to the rotor. To prevent it from being rotated,
A variable pitch propeller is installed as a small diameter rotor on the tail, and the variable pitch is adjusted so that the thrust is enough to cancel out the reaction torque of the rotor.In addition, two rotors that rotate in opposite directions are moved forward and backward. There are several self-made kits available, including a prototype with a ramjet installed at the tip of the rotor, and an autogyro that does not drive the rotor but allows it to rotate freely.

(c) Problems to be Solved by the Invention Conventional helicopters have complex drive structures for rotor blades and pressure section rotors, and long drive shafts that run into thick sections, making them prone to vibration and many troubles. It is also less economical in terms of fuel efficiency,
The operating speed is slow and there are some aspects that lack stability.

(d) Means for Solving the Problems The present invention will be explained with reference to the drawings. In Fig. 1, this is an overall structural diagram applied to a one-seater boat, and 1 is a rotor blade, which is normally The number of helicopters available ranges from two to several, but it is difficult to increase the number of helicopters due to their complex mechanisms. In the present invention, the rotor blades are fixed to the boss and have a simple and sturdy structure similar to a normal propeller, and the number of blades can be increased arbitrarily to reduce the overall deflection, resulting in a compact and stable structure. In this case, it is shown in 6 pieces. 2 is a wingtip rocket, and the rotor is driven by this thrust and is not mechanically driven from the aircraft body, so no reaction force is generated. 3 is a compressed air pipe which passes through the inside of the rotor and reaches the wing tip rocket 2. At the same time, 64 is a rotor shaft which also serves as a strength member of the rotor, which is also tubular in shape, through which compressed air is passed and supplied to the compressed air pipe 3 of the volume. In this case, seal with a labyrinth or gasket to prevent leakage from the rotating parts. 5 is the main engine; if it is small, an automobile engine is sufficient; if it is large, a gas turbine is used. 6 is an air compressor, which supplies compressed air to the wing tip rocket 2.

A clutch 7 connects and disconnects power between the main engine 5 and the air compressor 6. 8 is a propulsion propeller, which is similar to a normal airplane. 9 is a clutch, and the main engine 5
The power is connected and disconnected between the propeller 8 and the propulsion propeller 8. 10 is a cockpit. Reference numeral 11 designates the tail beam, which also uses a tube, into which compressed air is sent from the air compressor 6 and blown out from the thick part, and is used for attitude control at low speeds. Since this method can spray in any direction, up, down, left, or right, it is more useful for multidirectional control than the pressure section rotor. 12 is the tail. 1
3 is a wheel. Normal helicopters do not glide, so they only have skids, but this aircraft not only takes off vertically, but also glide. 14 is a fixed wing, and 615 is a fuel injection device, which is normally unnecessary but is provided when more economical operation is required, and injects it into compressed air and sends the mixture to the wing tip rocket 2. (E) Function Since a normal helicopter mechanically drives its rotor blades, the reaction force causes the aircraft to rotate in the opposite direction.

To prevent this, a rotor is installed in the thick part and a variable pitch propeller is used to generate side thrust.

On the other hand, in the present invention, since the rotor rotates due to the reaction of the gas ejected from the wingtip rocket 2 attached to the rotary wing tip, no reaction force is generated in the fuselage, and a side thruster-like mechanism is not required.

The air-fuel mixture is sent to the wingtip rocket 2, where it is combusted.
It ejects gas to generate thrust.

When large thrust is not required, fuel injection can be stopped and the injection of compressed air can be used alone.At high speeds, attitude control can be achieved using ailerons similar to those used in ordinary airplanes, but at low speeds, it is possible to control the attitude from the thick section. It is controlled like a rocket by an air jet. In conventional helicopters, the only way to move up and down is by changing the direction of lift by changing the pitch of the rotor blades 1, which is not easy to operate in conjunction with the forward thrust. In contrast, in the present invention, control can be easily performed using an air jet in the thick portion.

Further, the forward thrust is also obtained by the propulsion propeller 8, which is an independent and simple system.As long as it is an independent and simple system, the operation is mainly in vertical takeoff helicopter mode, and when taking off, the clutch 9 is disengaged and the propulsion propeller 8 is not driven. is normal.

Next, in the autogyro mode, fully heated compressed air is not sent to the rotor blade 1, or only for a short time at the time of start, and the vehicle takes off in a short runway, so the clutch 7 is disengaged and the vehicle is operated.

As an intermediate between the above two modes, it is also possible to perform an operation in which the fuel injection device 15 is not activated and only compressed air containing no fuel is constantly supplied.

It is a highly safe type of aircraft because it can be operated in a variety of ways, such as the 4゜2. It also has high fuel economy. In some cases, the rotor blades can also be fixed.

(f) Effects of the invention Recently, helicopters have become popular not only for access to airports and golf courses, but also for communication between general factories. In addition, small remote control helicopters are beginning to be used for spraying pesticides, and ultra-light planes are also becoming more popular, so there is a need for something simpler, cheaper and safer than current helicopters.

The present invention satisfies these demands and greatly contributes to the development of people's lives.
