Large high-maneuverability flapping-wing aircraft capable of hovering based on clapping effect

Abstract

The invention relates to a large high-maneuverability flapping-wing aircraft capable of hovering based on a clapping effect. The flapping power system comprises a first driving motor, an electronic speed regulator, a gear mechanism and an X-shaped layout wing, two wing beams of the X-shaped layout wing are arranged in a crossed mode and are fixedly connected with a fuselage in a rotatable mode, and the two wing beams of the X-shaped layout wing are fixedly connected with the fuselage in a rotatable mode. The two wing beams are rotatably and fixedly connected with the gear mechanism through twoconnecting rods respectively, and the gear mechanism controls the two wing beams to symmetrically swing relative to the fuselage in a linkage mode through the two connecting rods respectively, so that the wings in the X-shaped layout are symmetrically arranged in a linkage mode for striking; the tail rotor wing two-way propelling system comprises a tail rotor wing, a two-way electronic speed regulator and a second driving motor, and the second driving motor drives the tail rotor wing to rotate forwards and backwards to generate yawing moment; and the energy and flight control system comprisesa lithium battery and a flight control module and is used for providing energy and data acquisition, processing and output for the aircraft. According to the aircraft, flapping effects are generatedby wing flapping, the thrust is large, the task load is large, the tail rotor wing actively controls the course, the anti-interference performance is high, and course control is effectively achieved.

Description

technical field [0001] The present disclosure relates to the technical field of flapping-wing aircraft, in particular to a large-scale, highly maneuverable hovering-wing flapping-wing aircraft based on the snap-in effect. Background technique [0002] At present, flapping-wing aircrafts are mainly divided into two categories: bird-imitating flapping-wing aircrafts and insect-imitating flapping-wing aircrafts. Insect-like flapping-wing aircraft are generally miniature flapping-wing aircraft, which have small wing surfaces and high flapping frequency, and can achieve high maneuverability such as autonomous take-off and landing, hovering, and high-speed movement. However, the insect-like flapping-wing aircraft has limited battery life and load capacity, and its wind resistance is weak. It can achieve better flying effect indoors, but the effect is poor when flying outdoors. [0003] Most of the bird-like flapping-wing aircraft are large-scale flapping-wing aircraft, which adop...

Problems solved by technology

But for the large-scale flapping-wing aircraft such as bird-like flapping-wing aircraft, there is no test machine that can hover at present.

The reasons mainly include the following two points: One is the problem of insufficient thrust. The incoming flow is almost zero during the hovering stage of the aircraft. At this time, it is necessary to rely on the thrust generated by flapping to offset all the gravity. However, the mass of a large flapping-wing aircraft is large, so the flapping of the wings is very difficult. It is difficult to produce such a large thrust; the second is because of the problem of roll control during the hovering phase of the large-scale flapping-wing aircraft (that is, the heading control during the level flight stage). It is necessary to arrange the rudder surface at the position of the maximum wake velocity to improve the rudder effect, but generally speaking, the position of the maximum flow velocity is far away from the axis of the fuselage along the span direction. In addition, to ensure sufficient control efficiency, the rudder surface also needs to have Greater rigidity, in this way, the fuselage and rudder surface will pay a greater weight price, and the thrust required for hovering will also increase
