Embodiment Construction

[0024] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples and accompanying drawings. As a limitation of the present invention.

[0025] Such as Figures 1 to 2As shown, a fixed-wing long-endurance aircraft for vertical take-off and landing of the present invention includes a fuselage 1 in a horizontal position in the flight state, and the fuselage 1 is in a long streamlined structure, and a pair of wings is symmetrically installed on both sides of the head of the fuselage 1. For the canard 3, a pair of wings 2 are arranged at the tail of the fuselage 1, and the wing 2 is an upper monoplane layout with non-negative dihedral and non-negative sweep angles to increase the lateral heading stability of the aircraft. The trailing edge of wing 2 is equipped with aileron, and a vertical tail 4 is arranged below the fuselage 1 afterbody, and v...

Abstract

The invention discloses a vertical take-off and landing fixed-wing long-endurance aircraft, which comprises a fuselage in a horizontal position in the flight state, a pair of canards are installed on the head of the fuselage, and a pair of wings are arranged at the tail of the fuselage. A vertical empennage is arranged below the tail of the fuselage, and at least two pairs of even-numbered distributed power devices are arranged below the wings, and the rotating shafts of the power devices are distributed along the axis of the fuselage; at the head of the fuselage A vertically distributed through hole is arranged on the upper part, and a pitch control power with a rotating shaft vertically distributed is installed in the through hole. The pitch control power of the aircraft of the present invention outputs the required pitch control torque through the rotating speed and pitch of the variable pitch propeller in the entire flight envelope. The adjustable minimum pulse width of rotation and yaw control is smaller, and the 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] Since the vertical take-off and landing fixed-wing aircraft not only has the performance advantages of high flight speed, long range, and long flight time of fixed-wing aircraft, but also can complete take-off and landing in complex areas such as mountains, jungles, and surface ships with limited venues and airspaces. The practical value of taking off and landing fixed-wing aircraft has been widely recognized by the industry. [0003] At present, there are two types of vertical take-off and landing UAVs: tilting power type and tail seat type. The tilting power vertical take-off and landing 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 resistance along the horizontal direct...
