摘要
Abstract
The development of controllable flow solid ducted rocket promote the study on control system of solid ducted rocket. The control model is the foundation of the control system design. Based on the lumped parameter conception, a dynamic model of the controllable flow solid ducted rocket is established. The physical meaning of model parameters and the parameter variation characteristics of solid ducted rocket are analyzed. The dynamical response time of solid ducted rocket consistes of the cold volume time, the hot volume time, the shock propagation time and the shock volume time. The wide working conditions make solid ducted rocket possess strong parameter variation characteristics. Finally model reduction order is performed,and the frequency analysis results show that the model reduction order is reasonable.关键词
