Abstract

PURPOSE:To obtain an airplane with a good field of view by constituting the airplane arranging along the periphery of a rotary elliptic airframe a main rotor mounting its each blade to a rotatable annular unit coaxially provided in the airframe and driving and rotating by an engine this annular unit obtaining a lift. CONSTITUTION:An airplane forms its airframe 1 as a whole into a rotary elliptic shape formed in its upper part by a transparent material. This airframe 1 provides in its upper part 3 a crew room 16 and in the lower part 2 a baggage room 17 and a machinery room or the like. While this airframe 1 arranges along its periphery a main rotor 4 stored in its base part in an annular groove member 5 provided in a peripheral edge of the airframe 1. The main rotor 4 has many blades 6, and each blade 6 is connected in its base part to an annular unit 7 through a hinge 8 and in the outer edge to a ring 9, serving as a flywheel, through a ball joint 10. A lift is obtained by rotating the annular unit 7 by three engines 18 provided with an equal space, and propulsive force is obtained by rotating subrotors 21.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a saucer-shaped airplane that flies by rotation of a rotor.

[Conventional technology]

Helicopters are conventional airplanes that fly by rotating rotors.

[Problem to be solved by the invention]

Conventional helicopters have a body with a long, narrow tail attached to the head where the crew cabin is located, and the tail makes the body longer and more unstable.

In addition, because the main rotor is located at the top of the aircraft, the occupants feel pressured from above and have poor upward visibility.

[Means to solve the problem]

In order to solve the above problem, the present invention includes a spheroidal body, a main rotor is disposed along the outer periphery of the body, and each blade of the main rotor is rotatably attached to the body. connected to a coaxially mounted annulus;
A configuration is adopted in which an engine and a power transmission mechanism for transmitting the power of the engine as torque to the annular body are installed on the inner peripheral side of the annular body.

[Effect]

The fuselage has a novel, disc-shaped body with no tail, making it shorter and more stable due to its symmetrical shape.

Since the main rotor is located on the outer periphery of the aircraft, visibility above the aircraft is good and there is no feeling of pressure from overhead.

〔Example〕

Hereinafter, the present invention will be described in detail based on the drawings.

Embodiment 1 In FIGS. 1 and 2, reference numeral 1 indicates the aircraft body. The fuselage 1 is formed as a spheroid as a whole, and the lower part 2 is made of a strong material, while the upper part 3 is made of a transparent material to improve visibility. Further, a crew compartment 16 is provided in the upper part 3 of the fuselage, and a cargo compartment 17, a machine room, etc. are provided in the lower part 2 of the fuselage.

Further, reference numeral 4 indicates a main rotor, and the main rotor 4 is arranged along the outer periphery of the body 1, and its base is housed in an annular groove member 5 provided on the periphery of the body 1. .

The main rotor 4 has a number of blades 6, each connected at its base to a annulus 7 via a hinge 8 similar to that in conventional helicopters, and at its outer edge as a flywheel. It is connected via a ball joint 10 to a ring 9 which plays a role.

The annular body 7 is supported by bearings 11 on its upper and lower sides within the annular groove member 5, and internal teeth 12 as an internal gear are formed on the inner peripheral portion and mesh with a pinion 13. Thereby, the ring body 7 is attached coaxially to the body 1 and is rotatable.

A bearing 14 is also provided for each blade 6. This bearing 14 is provided over the entire circumference of the annular groove member 5, and can be moved up and down separately on the front side and the rear side of the body by a hydraulic pressure generator 15. This is a means for giving forward motion to the fuselage 1, and when the bearing 14a on the front side of the fuselage is lowered and the bearing 14b on the rear side of the fuselage is raised, the rotation circle of the rotor 4 tilts forward. This will provide forward thrust.

On the inner circumferential side of the ring body 7, three engines 18 and a power transmission mechanism for transmitting the power of the engines 18 to the ring body 7 as torque are installed at equal intervals. The power transmission mechanism includes the pinion 13, a speed reduction device, and the like.

In addition, a control device 20 is installed inside the aircraft 1 for the operator 19 to control the aircraft 1.
Outside, there is a sub-rotor which rotates by receiving power from the engine 18 to stop the rotation by the main rotor 4 of the fuselage 1.
21 are installed, and in order to further stabilize the fuselage 1, a horizontal plate 22 is installed at the front, a vertical plate 23 is installed at the rear, and legs 24 and wheels 25 are installed at the bottom.

In addition, in order to further increase the forward thrust by tilting the rotation circle of the rotor 4 forward, the lower part of the fuselage 1 is
Jet engines 29 are attached to the left and right sides of the. Note that a turboprop engine or other type of engine may be used instead of the jet engine.

In order to fly the above airplane, the pilot 19 operates the control device 20 to start the engine 18,
Rotate the main rotor 4. This generates lift and the aircraft 1 rises. Further, by tilting the blades 6 of the main rotor 4 slightly downward at the front side of the body 1 and slightly upward at the rear side of the body 1 using the hydraulic system 15, the body 1 moves forward. Note that the propulsion force of the aircraft can be further increased by starting the jet engine 29 as necessary.

Example 2 FIG. 3 shows the case of one type of coaxial reversing rotor.

The lower main rotor 27 has the same structure as in the first embodiment, but the upper main rotor 26 is different in that the ring body 13 has teeth 28 as external gears.

Therefore, the upper main rotor 26 and the lower main rotor 27 rotate in opposite directions to raise the fuselage 1. Further, since the rotation of the body 1 due to the rotation of the main rotor 4 in the first embodiment is also prevented, the installation of the auxiliary rotor 21 is no longer necessary.

〔Effect of the invention〕

As described above, the airplane according to the present invention has a spheroidal body, a main rotor is disposed along the outer periphery of the body, and each blade of the main rotor is coaxial with the body. The engine is connected to a ring body which is rotatably attached to the ring body, and an engine and a power transmission mechanism that transmits the power of the engine as torque to the ring body are installed on the inner peripheral side of the ring body. Because of this, the aircraft has a novel disc-shaped body that omits the tail of a conventional helicopter, and is symmetrical, making the aircraft stable in the air and shortening the aircraft's length. It is something that can be effective.

In addition, since the main rotor is located on the outer periphery of the aircraft rather than at the top, the occupants do not feel pressured from overhead, and the aircraft also has the advantage of extremely good upward visibility.
