Detailed Description

The invention discloses a novel unbreakable gyroplane, which comprises a gyroplane body and a rotor wing 6 arranged at the top of the gyroplane body, wherein an air bag umbrella 2 is arranged above the rotor wing, the air bag umbrella is an umbrella-shaped expanded air bag, and gas with density smaller than that of air, such as helium, is filled in the air bag. The term "umbrella shape" as used herein refers to a state in which the air bag is projected so as to cover the rotor in a position as extended as possible, and is not intended to limit the shape of the air bag, and the air bag umbrella may have any shape. The air bag parachute can standardize the posture of the gyroplane, so that the gyroplane can keep a vertical posture when losing power or falling on the water surface. According to the structural characteristics, the invention can also be called a 'crash-proof gyroplane with an airbag umbrella cap'.

In addition, the circular area corresponding to the rotating rotor wing preferably does not exceed the projection area of the air bag umbrella on the corresponding plane vertical to the axial lead of the rotor wing, so that the air flow driven by the rotating rotor wing almost completely flows to the air bag umbrella and serves as the source power for supporting the air bag umbrella, and the energy utilization rate is maximized.

Because the air bag umbrella can provide upward power which is not influenced by whether the rotor wings stop rotating or not as long as the air bag umbrella is in a normal state, the upward power provided by the air bag umbrella in the vertical direction can counteract partial gravity of the rotorcraft, so that the vertical posture of the rotorcraft can be standardized, and the rotorcraft can hover in the air can be facilitated.

The rotorcraft with the airbag umbrella caps can also be provided with an engine and a clutch, and when needed, the rotor is connected with the engine through the clutch, so that the rotor becomes a rotor with power. The engine provides a power source for the rotorcraft at a particular stage or process that causes the rotor to temporarily actively rotate. The power-driven rotor wing is mainly used for assisting in vertical take-off and landing.

In the take-off process, the rotor wing and the engine can be connected by the clutch, the rotor wing rotates actively to drive airflow to enable the air bag umbrella to obtain upward initial power, and the rotor wing also generates a certain lifting force, so that the rotor wing and the air bag umbrella are matched with each other to realize vertical take-off. Because the rotor wing and the air bag umbrella simultaneously provide ascending power, the vertical takeoff process can be shortened.

Taking the embodiment shown in the attached drawings as an example, the bracket can be fixedly installed relative to the rotating shaft, and the plane supporting ring of the bracket is kept parallel to the plane of the rotor wing. When the rotor tilts as required, the air bag umbrella tilts along with the rotor synchronously. The support also can adopt angularly adjustable mode to install on pivot or the fuselage to can be independent of the rotor is adjusted the inclination alone, makes the gyroplane can respond to more kinds, more complicated air current situation freely with more nimble and safe flight gesture in flight process.

The airbag umbrella is preferably of a bilaterally symmetrical structure.

The left and right side edges of the bracket are respectively fixedly provided with a left wing plate and a right wing plate 4 which extend leftwards and rightwards in the horizontal direction. The left wing plate and the right wing plate are also part of the bracket, and in this embodiment, are respectively fixed on the edges of the middle sections at the left and right sides of the plane support ring, and of course, the air bag umbrella and the left and right wing plates are also relatively fixed. The left and right wing plates may serve as extensions of the airbag umbrella in the left-right direction. The rotor wing is completely located in the shade range of the air bag umbrella, the left wing plate and the right wing plate in the left-right direction. In the embodiment shown in the figures, in which the centre of the bracket is fixed to the axis of rotation of the rotor, the diameter of the rotor is not greater than the distance between the points of the left and right wing plates that are furthest apart.
