双滑轨式机翼前掠机构设计

Abstract

Abstract: In order to meet the of aerodynamic and structural requirements in a morphing aircraft, this paper proposes a switching mechanism with a double slideway based on the variable forward-swept wing configuration which makes it possible for the aircraft to switch among orthogonal wing, forward-swept wing and delta wing freely. First, the general configuration of the wing-body switching mechanism with a double slideway is elucidated by means of a block diagram and a three-dimensional model plot. Then, an idiographic explanation is provided for the project. Finally, a comparison is made between the wing-body switching mechanism with double slideway and the traditional switching mechanism in terms of function and structure, and it is shown that the wing-body switching mechanism with double slideway can meet the aerodynamic requirements better; moreover, it reduces the stress at the root of the wing by 35.6%, the stress of the axes by 7.2%. Therefore, this mechanism may serve as a useful reference when developing a morphing aircraft.
