Abstract

The invention discloses an aircraft comprising a body and wings. The wings include one pair of main sweepback wing planes and one pair of secondary sweepforward wing planes. The main wing planes and the secondary wing planes are connected by wing links. The main wing planes and the body are connected by front hinges. The body includes a sliding block and a sliding block driving unit; and the sliding block driving unit is controlled to drive the sliding block to make forward and backward movement. The secondary wing planes and the sliding block are connected by rear hinges. The sliding block isdriven by the sliding block driving unit to slide forward and backward along the body, thereby changing the included angles between the main wing planes and the secondary wing planes and the body. According to the invention, the included angles between the wings and the body can be changed; and the optimal pneumatic lift-to-drag efficiency is obtained.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to an aircraft. Background technique [0002] The angle between the wing and the fuselage of conventional aircraft is fixed. For example, an aircraft flying at a low speed adopts a form where the wings are perpendicular to the fuselage in order to obtain greater lift; However, the speed of the aircraft is not constant during the entire flight process. In the entire speed range, only the aircraft whose angle between the wing and the fuselage is fixed at a specific speed can obtain Excellent aerodynamic lift and drag efficiency. [0003] According to the applicant's research, it is found that some fighters or bombers install very complex deformation devices at the connection between the wings and the fuselage, and the angle between the wings and the fuselage is driven to change. This kind of aircraft has the problems of narrow installation space of the deformation device, high co...
