Review of Real-Time Optimal Guidance System Using Dynamically Distributed Genetic Algorithm for Experimental Winged Rocket WIRES#015

In recent years, attention has been focused on fully reusable space transportation system with low operation cost for further promotion of space development. As part of this, the development of experimental winged rocket which is called WIRES (WInged REusable Sounding rocket) is being conducted at Space Systems Laboratory, Kyushu Institute of Technology. As one of its key technologies, a real-time guidance system that generates flight trajectories without reference trajectories using a DynDGA (Dynamically Distributed Genetic Algorithm) is studied. This guidance system can generate the flight trajectory even if the situation suddenly changes such as abort flight. The flight demonstration of this guidance system is currently planned using the WIRES#015 which is under development. For this guidance system validation, the 6 degree-of-freedom simulation, where DynDGA guidance system is applied to the gliding phase, is conducted. In this paper, the construction of guidance system for WIRES#015 and its simulation result are discussed.
