| Outline of Final Research Achievements |
A new concept of space transportation system, whose configuration changes in order to realize suitable aerodynamic performance in each flight condition, has been proposed by authors. In our previous studies on fully RLV, the present authors discovered a vehicle, whose fuselage has cross section of triangle, has high aerodynamic characteristics in subsonic flight regime. By using the configuration as base line model the present authors aim to apply morphing technique to all flight regimes, so called Morphing RLV. In hypersonic flight condition delta wing based, wave rider configuration has be proved to have higher aerodynamic characteristics and in subsonic flight condition base line configuration with strake or sharp corner at cross section of fuselage has be proved to have higher aerodynamic characteristics. Those results have been explained in the several domestic and international symposium and highly evaluated.
