Abort Trajectory Optimization Using an hp-Adaptive Pseudospectral Method

摘要：

Mission abort scenarios of RLV due to an engine failure which leads to engine cut-off are considered. The abort trajectory optimization problem is treated as a maximum range problem for abort capability analysis. An hp-adaptive pseudospectral method be employed to solve this problem because of its accuracy and computational efficiency. Fuel jettisoning rate is treated as a optimization parameter. Numerical results show the optimal fuel jettison rate is its maximum value and the maximum longitudinal range achievable with fuel jettisoning is increased by 7.62％ when compared to the case without fuel jettisoning.
