- Design Optimization of Blended-Wing-Body-Type Flyback Booster in View of Aerodynamics, Aerodynamic Heating, and Empty Weight
抄録
Fulfillment of reusable launch vehicle is essential as it is one of economic and efficient space transportation methods. In this research, the geometry optimization of TSTO flyback booster was performed based on the optimal trajectory result of WIRES of Kyushu Institute of Technology for three objectives: aerodynamics, aerodynamic heating, and structural weight. We assume a hybrid wing body as a 3D geometry of flyback booster. CFD analysis by FaSTAR is performed to evaluate the objective functions; multiobjective optimization is implemented using SPEA2 which is a kind of evolutionary computation. Moreover, data analysis is carried out on the optimization result; we revealed information in the objective space. Consequently, we have understood that there are differences how to raise lift to drag ratio at subsonic and supersonic, hypersonic. It is an efficient way to make nose of fuselage blunt and bottom flat for minimizing maximum temperature on the body surface.
