Integrated entry simulation model for reusable launch vehicle

A novel integrated guidance/control simulation model with high accuracy for reusable launch vehicle (RLV) was proposed. Based on the accurate nonlinear flight dynamics of RLV, the flight manager was established, featuring the flight corridor and effectors health status, which meets the requirement of nominal flight management, guidance/control reconfiguration under off-nominal conditions, and transitioning to an abort mode in response to a more serious situation. Afterwards, utilizing the finite state machine and algorithm interface via Stateflow technique, the convenience and applicability of implementation are enhanced remarkably. Integrated guidance/control reconfiguration in the presence of effector failures is presented to demonstrate the capacity of this proposed model.
