Problems solved by technology

However, the manufacturing and installation of these guide vanes are still relatively complicated, and the streamlines may be chaotic during flight, resulting in relatively large forward flight resistance, which will affect the stability and speed of the helicopter.

Embodiment Construction

[0039] In Fig. 1, it shows the stressed state when the helicopter is flying forward, the main rotor disk is tilted forward under the action of the automatic tilter (2), and the acting force F of the main rotor to the fuselage can be decomposed into two parts F1 and F2. A force component, where F1 is balanced with the weight G of the helicopter. F2 makes the aircraft fly forward, but there is a distance H between F2 and the center of gravity O, which produces a force couple M1, but M1 makes the fuselage tilt forward. In order to reduce this inclination range, the present invention sprays air simultaneously through the downward solenoid valve nozzle (6) and the upward solenoid valve nozzle (19) installed on the gas storage ring tank (17), and the force couple M2 produced can balance M1, thereby making When the helicopter changes from the hovering state to flying forward suddenly, the fuselage will not tilt forward excessively due to the lack of a horizontal tail to affect the co...

Abstract

A circular helicopter is composed of semi-spherical main body, engine, rotary wings, landing chassis, inflatable ring tank under the main body and the nozzles with electromagnetic valve. It features that said inflatable ring tank and the annularly arranged nozzles are used to balance the torque generated by rotary rings and control flying direction. Its advantage is high stability and safety.

Description

Technical field: [0001] The invention relates to a helicopter with a hemispherical fuselage, in particular to a circular helicopter with no tail boom, no tail rotor, compact structure and safer flight. Background technique: [0002] At present, known helicopter mainly is made up of fuselage, engine, main rotor, tail boom and tail rotor. When the lift generated by the main rotor driven by the engine is greater than the total weight of the helicopter, the helicopter will fly off the ground. And when the main rotor disc is tilted forward, the helicopter flies forward. However, the reaction force of the main rotor to the fuselage will cause the fuselage to reverse continuously, causing the pilot to be unable to control the flight direction. For this reason, a tail beam and a tail rotor are usually added at the tail of the fuselage to balance the reverse and control of the fuselage. flight direction. Because the fuselage is thick and long, and the dynamic field of the main rot...
