| 摘 要： | 应用CFD方法研究了两级重复使用运载器上升段和轨道器再入段的气动性能.结果表明:轨道器升阻性能、纵向静稳定性能、横向静稳定性能及亚、跨声速段航向静稳定性能均满足气动总体设计基本要求,其它性能有待改进;运载器上升段气动性能与一般运载火箭类似,只是升阻比偏高,使用摆动喷管后可以保证纵向和横向稳定性.

| Abstract: | The aerodynamic performance of a tandem two-stage-to-orbit(TSTO) reusable launch vehicle(RLV) and its reentry orbiter are studied through employing computational fluid dynamic(CFD) method.The result shows that: the orbiter's property about lift-drag and longitudinal-lateral-directional stability can satisfy the basic requirement,and other aerodynamic properties should be improved;the aerodynamic performance of the combination body of launch vehicle is similar to traditional launch vehicle except for higher lift-drag ratio,and the longitudinal and directional instability can be controlled effectively by swing nozzles. |
