Research on Motion Characteristics in Opening Process of Aircraft Deformed Wing

Abstract

Deformed wing mechanism is a developed system of aircraft for miniaturization, which is convenient for box (cylinder) storage, transportation and launch, thus can save the storage and transportation space of aircraft and can improve the space utilization performance of flight system. In order to study wing dynamic opening motion characteristics during aircraft flight, based on gas theory and structural dynamics, this paper studies the dynamic process of the rotary opening movement of deformed wing system caused by the pressure acting on the piston because of propellant combustion with different charge amounts in the chamber, and analyzes relationship between the opening angle of inner and outer wings, angular velocity with time under different gas pressure. The results show that the opening motion of the deformed wing is sensitive to the initial conditions, and different motion characteristics is reflected at different gas pressures.
