Abstract

The invention provides a morphing aircraft with variable swept wings and head deflection. The morphing aircraft comprises an aircraft head, an aircraft fuselage, a left swept wing, a right swept wing, a head deflection device and a swept wing deflection device. Wherein the head deflection device is arranged between the head of the aircraft and the fuselage of the aircraft; the sweeping wing deflection device is arranged between the left sweeping wing and the right sweeping wing; the head deflection device is used for controlling the aircraft head to deflect; and the sweeping wing deflection device is used for controlling the left sweeping wing and the right sweeping wing to sweep. According to the morphing aircraft, the streamline of the aircraft body is smooth, the deformation mechanism principle is simple and easy to achieve, and the aerodynamic performance of the aircraft in subsonic velocity and low supersonic velocity flight is improved by means of aerodynamic shape changes of the aircraft head and the swept wings.

Description

technical field

[0001] The application relates to the technical field of variant flying chess design, in particular to a variant aircraft with variable-sweep wings and head deflection. Background technique

[0002] The task required by the aircraft is more complex, and the design is only for a fixed-shaped aircraft. The result of the design must be a trade-off under various working conditions, sacrificing the drag of subsonic flight in order to meet the lift of subsonic flight. That is to say, the aerodynamic characteristics of fixed-wing aircraft with multi-working conditions are not optimal in each speed range.

[0003] In order to solve the above problems, the researchers proposed a variant aircraft, which can change the aerodynamic layout of the aircraft according to the changes of the flight environment and flight tasks, and maintain the optimal flight performance, so that the aircraft can perform various tasks at different altitudes and different flight speeds. requir...
