A kind of vertical-horizontal dual-purpose aircraft and its flight mode switching method

Abstract

The invention discloses a vertical-horizontal dual-purpose aircraft and its flight mode conversion method, including three conversion modes. The first one is that the upper and lower propellers rotate 90 degrees in the axial direction of the wing and the forward horizontal direction of the fuselage at the same time, changing the flight mode. Mode; the second, the upper propeller first, the lower propeller behind the wing axis, and the fuselage forward and horizontally rotate 90 degrees to change the flight mode; the third, the lower propeller first, the upper propeller behind the wing axis, and the fuselage direction Rotate the front horizontally 90 degrees to change the flight mode, and complete the conversion from multi-rotor flight mode to fixed-wing flight mode. Conversely, to switch the flight mode from the fixed-wing flight mode to the multi-rotor flight mode, it is only necessary to perform the steps of the above three flight mode conversion methods in reverse order.

Description

Technical field [0001] The invention relates to the technical field of aircraft, in particular to a vertical and horizontal dual-purpose aircraft and a flight mode conversion method thereof. Background technique [0002] Aircraft is a large category of aircraft, which refers to any machine that obtains aerodynamic lift and flight through the relative movement of the fuselage and the air (not the reaction of the air on the ground). Including balloons, airships, airplanes, gliders, rotorcraft, helicopters, flapping wing aircraft, tilt rotor aircraft, etc. An airplane is a common type of aircraft. [0003] Existing aircraft flight mode conversion methods mostly adopt a single conversion mode (for example: China's vertical dual-purpose aircraft "Blue Whale", American Osprey V-22), there is no intermediate transition mode, no backup power, the aircraft is switching flight modes The down flight is extremely unstable and the controllability is reduced, which is extremely dangerous.

[0003] Existing aircraft flight mode conversion methods mostly adopt a single conversion mode (for example: China's vertical-level dual-purpose aircraft "Blue Whale", American Osprey V-22), there is no intermediate transition mode, no backup power, and the aircraft is switching flight modes The flight is extremely unstable, the controllability is reduced, and it is extremely dangerous

The existing technology has reached the limit bottleneck, and it is difficult to break through for a while, so we can only resort to methods and structures other than technology
