Abstract

For morphing flight vehicles, the changes of sweep angle and span have great influence on key parameters such as aerodynamic forces, inertial moments, pressure center and gravity center. A dynamic model of morphing vehicle with variable sweep and span is established based on Newton-Euler method. The additional force and moment generalized by morphing are deduced. The dynamic response aroused by morphing is studied using decoupled longitudinal equations and quasi-steady aerodynamic model. The results indicate that the changes of sweep and span influence the dynamic characteristics severely; however, the effect of different morphing speed is not remarkable. Appropriate strategy of morphing could weaken the fluctuation of dynamic parameters and relieve the burden of control system.
