Hirosaki Bunka Center), Hirosaki, Aomori, Japan, To promote the space utilization, reusable space planes have been attracting our attention from a viewpoint of the cost reduction in transportation. Among various design concepts, in the present study, we consider the space plane with the RBCC (Rocket-Based-Combined-Cycle) engines because of its wide coverage of the operation velocity at Mach number from 0 to 10 and above. However, the flow around the vehicle significantly interferes with the flow from the core rocket. To understand the fundamental nature of the aerodynamic characteristics of the space plane with RBCC engines, the two-dimensional Euler analysis has been conducted. The thrust performance is evaluated by the effective specific impulse, considering both the thrust and the drag force. The results show that the effective specific impulse exceeds the specific impulse of the pure rocket engine at the Mach number less than 7. The effects of the cowl shape, the main body shape and so on are also investigated. Additional analysis has been conducted to clarify the influence of the cowl and the rocket jet upon the aerodynamic characteristics. As a result of this analysis, it is shown that both the drag and the lift decrease by the cowl. On the other hand, the drag decrease and the lift increases by the jet of the rocket engine. Consequently, the aerodynamic characteristics are expected by the jet flow from the rocket engine, if the engine configuration, especially the position of the cowl, is appropriately designed., 形態: カラー図版あり, Physical characteristics: Original contains color illustrations, 資料番号: AA1530023015, レポート番号: JAXA-SP-14-010}, pages = {81--86}, publisher = {宇宙航空研究開発機構(JAXA), Japan Aerospace Exploration Agency (JAXA)}, title = {RBCCエンジン搭載スペースプレーン極超音速空力性能の機体・推進統合解析}, volume = {JAXA-SP-14-010}, year = {2015} }
