Emergency Guidance Law for Reusable Transportation System

摘要：

This paper proposes a new emergency guidance and control law for future reusable space transportation systems, such as spaceplane. The reusable transportation system is required to return to the landing area safely even if unexpected malfunction causes and the mission is aborted. Low computational load is necessary for the emergency guidance law because reference trajectory must be calculated through an onboard computer within a shortperiod. And also the reference trajectory is required to be followed by a spaceplane with low performance in maneuver. The authors have proposed an emergency guidance and control law that generates a three dimensional trajectory without iterative calculatioa In this paper, the guidance law is improved for the low initial energy cases. Numerical examples show that the tracking error is small during flight to follow the reference trajectory generated by the proposed guidance law.
