Embodiment

[0026] like Figures 1 to 2As shown in the figure, a fixed-wing long-endurance aircraft with vertical take-off and landing of the present invention includes a fuselage 1 in a horizontal position in a flying state. The fuselage 1 has a long streamlined structure. For the canard 3, a pair of wings 2 are arranged at the tail of the fuselage 1. The wings 2 are of upper monoplane layout with non-negative dihedral angle and non-negative sweep angle, which increases the lateral and heading stability of the aircraft. Ailerons are installed on the trailing edge of the wing 2, a vertical tail 4 is provided below the tail of the fuselage 1, the vertical tail 4 is downward, and a rudder is installed on its trailing edge, and the wing of the wing 2 is slightly and the vertical tail 4. The wing points together form three support points. When in the stop state, the three support points make the aircraft park on the ground vertically upward; four distributed power devices 5 are arranged under...

Abstract

The invention discloses a vertical take-off and landing fixed wing long-endurance air vehicle. The vertical take-off and landing fixed wing long-endurance air vehicle comprises a fuselage in horizontal position in flight; the head part of the fuselage is provided with a pair of canard type wings; the tail part of the fuselage is provided with a pair of wings; a vertical empennage is arranged below the tail part of the fuselage; the lower parts of the wings are provided with at least two pairs of distributed power plants, wherein the number of the power plants is even, and the revolving shafts of the power plants are arranged along the axis of the fuselage; the head part of the fuselage is provided with a vertically distributed through hole; and an elevating control power plant is arranged in the through hole, and the revolving shaft of the elevating control power plant is arranged in vertical. According to the vertical take-off and landing fixed wing long-endurance air vehicle, the elevating control power plant is used for changing rotating aped of variable pitch propellers and elevating control moment force needed by screw pitch output in the whole flight envelope; the number of fixed pitch propellers is larger, and rotating speed of each propeller can be controlled individually, so that rolling and yaw control adjustable minimum pulse-width is smaller, and control accuracy is higher.

Description

technical field [0001] The invention relates to a fixed-wing aircraft, in particular to a vertical take-off and landing fixed-wing long-endurance aircraft. Background technique [0002] Because the vertical take-off and landing fixed-wing aircraft has the performance advantages of high flight speed, long range and long flight time of fixed-wing aircraft, and can complete take-off and landing in complex areas such as mountains, jungles and surface ships with limited venues and airspace, therefore, vertical The practical value of take-off and landing fixed-wing aircraft is more and more widely recognized by the industry. [0003] At present, there are two types of vertical take-off and landing unmanned aerial vehicles: tilting power type and tailstock type. The tilting power VTOL UAV realizes the mutual conversion of the rotor or jet engine from horizontal to vertical through the tilting mechanism. When flying horizontally, the power overcomes the resistance in the horizontal...
