Helicopter taking off and landing vertically and flying horizontally and application thereof

Abstract

The invention discloses a helicopter taking off and landing vertically and flying horizontally and application thereof. The helicopter comprises a fuselage, rotor mechanisms, wing mechanisms, an undercarriage device, a power mechanism, a control mechanism and a transmission mechanism. The fuselage comprises a nose, a fuselage middle part and a tail. The rotor mechanisms comprise double rotating rotor mechanisms. Rotary double-rotor mechanisms are longitudinally arranged on the fuselage. The multiple wing mechanisms are perpendicularly arranged on the two sides of the fuselage middle part. As both the double rotating rotor mechanisms and the rotary double-rotor mechanisms are designed, both vertical taking-off and landing and rapid horizontal flying are achieved; as the rotor mechanisms are installed on the nose and the tail of the fuselage of the helicopter respectively and can rotate front and back around the center axis of the fuselage, the range of the helicopter is 5-6 times larger than that of an existing helicopter, flight safety is ensured, production and operation cost is reduced, the design can be applied to various aircrafts, and the significant technical effects of a large range, a high flight speed, a high safety coefficient and control easiness of the helicopter can be achieved.

Description

technical field [0001] The invention belongs to the technical field of aircraft design, and more specifically, the invention relates to the technical field of a helicopter capable of rapid vertical take-off and landing and high-speed horizontal flight. Background technique [0002] There are basically two types of helicopters currently used at home and abroad. The first one is to set a parallel large propeller directly above the fuselage to be responsible for the aircraft's ascent and forward flight, and to set a horizontal rotation behind the fuselage. The small propellers in the left and right flight directions of the aircraft; the second is to set a propeller in the front above the helicopter and a propeller in the back. The flight speed is slow and the fuel consumption is high. And the helicopter used in the military not only requires that the helicopter can take off and land quickly, but also requires that it can maintain a certain speed when flying horizontally. Usua...

[0002] There are basically two types of helicopters currently used at home and abroad. The first one is to set a parallel large propeller directly above the fuselage to be responsible for the aircraft's ascent and forward flight, and to set a horizontal rotation behind the fuselage. The small propellers in the left and right flight directions of the aircraft; the second is to set a propeller in the front above the helicopter and a propeller in the back. Slow flight speed and high fuel consumption

However, the tilt-rotor aircraft has inherent serious defects. The engine of the tilt-rotor aircraft is placed on the tip of the fixed wing, which makes the fixed wing a cantilever beam with bad stress. This is an important reason for the hidden danger of stability. At the same time, this The propeller blades are symmetrically installed on both sides of the aircraft, and the gravity and gravitational points of the tilt rotor are arranged perpendicular to the fuselage. From a mechanical point of view, it will also cause many technical defects and safety hazards such as vertical lift, horizontal flight, and operational safety of the aircraft.

[0006] Among the above-mentioned three types of aircraft in the prior art, the V-22 "Osprey" is too electronic. Once a failure occurs, it cannot be rescued, and the safety factor is low. When a set of propeller blades is damaged, the aircraft cannot avoid crash accidents. more difficult problems
