Abstract
A new type of concept, "a rocket plane system of a horizontal take off and landing from the water" has been proposed. To explore the possibility of this concept, various experiments using "POC (Proof of Concept)" models are being conducted. In this paper, a flight control system for a horizontal take-off and landing spaceplane is presented. Especially we refer to the design method of a guidance and control system. To verify the performance of the flight control system, the Monte Carlo simulation of nonlinear 6-DOF aircraft model was carried out. As a result, it was confirmed the flight control system has good performance.
