Abstract:
Abstract: According to the initial position of reusable launch vehicles (RLV) in terminal area energy management (TAEM), the lateral reference trajectory is planned to erase the initial position errors using the SNAKE algorithm. The course of lateral reference trajectory planning can be divided into two phases: erasing the lateral position error and erasing the longitudinal error. In the former phase, the longitudinal error is decreased. For erasing the longitudinal error, we propose to erase the error by proper trajectory mode according to its size. The lateral trajectory planning algorithm provides a kernel algorithm for 3-D TAEM trajectory generation which is a basis of onboard trajectory generation of RLVs’ TAEM guidance.
