JPH048699A - Air jet rotary wing aircraft - Google Patents

Abstract

PURPOSE:To obtain an extremely safe aircraft by generating lift using a rotary wing rotated by a jet of air, and moving an air jet rotary wing aircraft in a direction freely decided by inclination of a rotary face, and providing a parachute hanger at the upper end of the aircraft and an air bag in the lower portion of the aircraft. CONSTITUTION:A rotary wing 1 is driven by reaction exerted by a jet of air injected from an air jet nozzle 3 and the inclination and direction of a rotary wing shaft 4 are freely decided by a control stick 8 and the rotary face of the rotary wing 1 is inclined in the freely decided direction accordingly and an air jet rotary wing aircraft advances in the direction. An auxiliary jet of air 12 acts between the rotary wing 1 and the rotary wing shaft 4 and corresponds to rotary torque and, or changes the direction of a cabine 7. An air bag 13 expands to almost the same size as a skid 11 when actuated and absorbs the impact of landing and functions as a buoy when the aircraft lands on the water. A paracute hanger 6 is a simple capsule which is dislocked in case of emmergency and opens a parachute to realize a safe descent.

Description

[Detailed description of the invention] (b) Industrial application fields This invention relates to improvements in vertical takeoff aircraft.

(b) Conventional technology There are platform-like platforms known as flying platforms for vertical takeoff, and platforms that use an engine carried on the back.

All of these systems utilize the jet engine's thrust, so they are extremely sophisticated.

(c) Problems to be solved by the invention This jet engine type is excellent in that it is compact, but if the engine stops, it will immediately crash and cause an accident, and it is overcrowded. It does not have the gliding ability of a winged aircraft, and it does not have the large lift generated by the rotary wings of a helicopter or Shilocopter, which is useful when stopping the aircraft.

(d) Means for Solving the Problems The present invention will be explained with reference to the drawings. In Fig. 1, this is an overall configuration diagram applied to a two-seater vehicle. 1 is a rotary blade, and about 6 radial blades are shown in Fig. 1. It has a fixed and sturdy structure that does not change the pitch, and the figure shows the rotating surface tilted forward for forward movement. Reference numeral 2 denotes an air pipe, which guides compressed air and at the same time serves as a support for the rotor blade 1.

The rotary blade 1 is attached on an extension of the air vibe 2.

Reference numeral 3 denotes an air jet nozzle, which is provided at the tip of the radial air vibe 2 in the direction perpendicular to the tangential direction of the rotating circumference. 4 is the rotor axis, which does not rotate (only one inclination can be changed).

In addition, this is a hollow shaft that guides compressed air.
It gives you the freedom to change the slope. In addition, the second rotor shaft 4
The support is a universal joint type, which also allows for free tilt changes. Reference numeral 5 denotes a rotary vane host, which is rotatably attached to the rotary vane shaft 4, and has the air vibes 2 radially attached thereto.

In order to send compressed air through the interior of the rotor shaft 4, a hole for the passage of the compressed air is provided at a location where the rotor shaft 4 intersects with the rotor boss 5. Compressed air is thereby sent to the air vibrator 2.

At this time, a labyrinth gasket or the like is installed to prevent compressed air from leaking between the rotating rotor boss 5 and the fixed rotor shaft 4.
Provide a gasket with less rotational friction. The pressure of compressed air is low, up to several atmospheres, and some leakage can be tolerated.
Even simple things are a problem; I'm not talented. In addition, a thrust l pairing is provided to withstand the axial thrust equivalent to the lifting force of the rotary blade 1.

6 is a parachute hangar, and in an emergency, this can be unlocked using gunpowder and the parachute can be activated. It rotates and is conveniently mounted on the tip of the rotary shaft 4.

7 is the cabin, which is equipped with simple windshield equipment to maintain the comfort of the pilot. 8 is a control stick, and by operating this, the inclination and direction of the rotating shaft 4 can be changed, and the vehicle can proceed in any direction. 9 is the engine, which is usually a car engine. 10 is a compressor that utilizes a low pressure rotary. The second compressed air is guided to the hollow rotating shaft 4. A rubber hose is used for a part of the rotation, and the rotating shaft 4 is provided with a control stick 8 to provide flexibility in changing its inclination and direction. Since this maneuvering force is a certain amount, compressed air pressure is used to reduce the maneuvering force by using the Surho drive method, which uses the vacuum pressure of the Kallin engine. This is similar to the incubator system for keys and steering wheels in automobiles.

11 is the skid, which serves as the foot when landing.
It consists of a lightweight and flexible vibrator. Reference numeral 12 denotes auxiliary air jet nozzles, and two of them can generate torque together, and the direction of the nozzles can be changed arbitrarily, so that the cabin 7 can be directed in any direction. 13 is an air bang,
Like those in modern cars, it is activated in an emergency.

However, in terms of structure, it is a more sturdy bag that is made by Atsunai.

(E) Function Unlike a normal helicopter, the rotor blades are not mechanically driven, but the rotor blades 1 are driven by the reaction force of the air jet ejected from the air jet nozzle 3, so there is no reaction force on the aircraft body. This does not occur and there is no need for a mechanism to cancel it.

In addition, the rotor axis 4 can be tilted and directed in any direction using the control stick 8, and the rotating surface of the rotor 1 can be moved in any direction around the entire circumference, front, rear, left, and right. The lifting force produces a horizontal force in that direction, and the object moves in that direction.

Ordinary helicopters have a complex structure in which the axis of rotation (one tilt is fixed, mostly vertical, and the pitch of the rotor blades is variable, changing depending on the angle during rotation to produce a horizontal component of force). In comparison, the present invention is very simple and robust.

Since the rotor shaft 4 is supported by a universal joint, the tilt and direction of the rotary blade shaft 4 can be changed using a control stick 8 to determine the direction of travel.

Since there is almost no friction between the rotor blade 1 and the rotary shaft 4, no torque is applied, but in preparation for the slight residual friction torque, the auxiliary air jet 12 is activated to cope with this torque, and the cabin 7 change the direction of

When the airbag 13 is activated, the skid 4 degrees 11;
Absorbs J attack. It also serves as a buoy when landing on water.

The parachute hangar 6 is a simple capsule that can be used for emergencies,
When it is ready, it is unlocked using gunpowder, etc. 1, and the internal parachute is opened to achieve a safe descent.

Normally, rotary wings differ from fixed wings in that even if the engine stops, the lift generated by the rotation of the rotor wing is maintained by hovering, making it highly safe, but in the present invention, this parachute further doubles safety. Ru.

(f) Effects of the invention: An extremely safe aircraft can be obtained, which can be used to spray pesticides, save lives, observe high altitudes, and improve the lives of people by using a remote-controlled aero hotter, and by using a safer helicopter to transport people to depopulated areas. There are many things that contribute to this.
