The Analysis of Motion Characteristics of Variable Forward-swept Wing Mechanism with a Double Slideways

Based on the variable forward-swept wing configuration, this paper utilized a variable forward-swept wing mechanism with a double slideways, which make it possible for the aircraft to switch among orthogonal wing, forward-swept wing and delta wing freely. The general configuration of the variable forward-swept wing mechanism with a double slideways was elucidated by means of a three-dimensional model plot and then the mathematic simulation model was also established. The motion characteristics of linear motion were simulated, analyzed and optimized. The results indicated that the variable forward-swept wing mechanism with a double slideways can meet the aerodynamic requirements better. Moreover, there exists great linear relationship between the position of nut and the wing forward-swept angle. Therefore, this mechanism may serve as a useful reference when developing a morphing aircraft.
