Abstract

With the numerical virtual flight technology based on structured overlapping grid, closed PID controller, rudder control, rigid body motion and unsteady N-S equation solver, the unsteady motion characteristic, dynamic stability and adjustment of control parameter of Genesis capsule and basic finner projectile have been simulated. The motion characteristic with different degree of freedom (DOF) motion, the motion stability and the adjustment of control parameter with disturbance of those flying vehicles have been analyzed. The calculation results show that the study of flying vehicle's nonlinear motion under the condition of complex fluid flows can be effectively carried out by numerical virtual flight technology, which has practical value and application prospect in the area of simulation and prediction of flying vehicle's motion and controlling characteristic, fluid mechanics study and design of control rule under the condition of unsteady and nonlinear aerodynamics.
