Embodiment 1

[0038] Such as image 3 , Figure 4 with Figure 5 As shown, the aircraft 100 of the present invention has a fuselage 110, a wing 120, an empennage 130, a landing gear 180 made up of a front leg 181 and a rear leg 182, and the first rotor power unit 140 symmetrically distributed on both sides of the fuselage 110 And the second rotor power unit 150 , the third rotor power unit 160 which is tiltably arranged in the middle of the empennage 130 in the width direction. The rotation axis of the first rotor power unit 140 and the rotation axis of the second rotor power unit 150 point to the rear and the lower part of the fuselage 110 . Preferably, the first rotor power unit 140, the second rotor power unit 150 and the third rotor power unit 160 are equidistantly distributed, that is, the first rotor power unit 140, the second rotor power unit 150 and the third rotor power unit 160 The centers are distributed on the vertices of the equilateral triangle. Further, in the height dire...

Abstract

The invention relates to a perpendicular take-off and landing aircraft which comprises an aircraft body, wings, an empennage, an undercarriage, a first rotor wing power unit and a second rotor wing power unit. The first rotor wing power unit and the second rotor wing power unit are located on the two sides of the aircraft body respectively and are arranged on the wings. The first rotor wing power unit and the second rotor wing power unit are symmetrically distributed on the two sides of the aircraft body. The rotating axis of the first rotor wing power unit and the rotating axis of the second rotor wing power unit point to the rear lower side of the aircraft body. A third rotor wing power unit can be obliquely and rotationally arranged in the middle of the empennage in the width direction. The perpendicular take-off and landing aircraft is good in balance, high in maneuverability and environment adaptability, high in posture switching reliability and capable of saving energy.

Description

technical field [0001] The invention relates to an aircraft, in particular to a vertical take-off and landing aircraft, in particular to a vertical take-off and landing aircraft with a rotor power unit. Background technique [0002] In 1991, the U.S. V22 "Osprey" tilt-rotor aircraft won the "Major Aviation Progress Award" issued by the National Aeronautics Association. At the same time, due to the frequent major accidents of the tilt-rotor aircraft, high development costs, complex and difficult technologies, and long development cycles , has also aroused great controversy. [0003] "Osprey" includes the fuselage, wings, empennage, landing gear, engines and tilt-rotor units. The wings are provided with ailerons, the tail is provided with elevators and rudders, the engine is located in the fuselage, and the tilt rotor unit is located at the two ends of the wings. When the axis of rotation of the rotor of the tilt-rotor unit is vertical, the rotor provides power for vertical ...
