有动力通用航空飞行器的概念研究

Conceptual Research on Powered Common Aero Vehicle

文章回顾了美国猎鹰计划的发展情况,为避开该计划采用的无动力通用航空飞行器(Common Aero Vehicle,CAV)方案面临的技术难题,提出了有动力CAV方案。对有动力CAV的关键技术——推进系统的选择、外形设计问题、轨迹设计问题分别进行了研究,给出了可供参考的方案。在不同发动机的模型下进行了备选轨迹的计算,结论指出外形与轨迹的一体化设计可以提高飞行器总体性能。

We review the development of the Falcon program of the US.To avoid the difficulties in developing un-powered Common Aero Vehicle(CAV) adopted by the program,we propose the conceptual powered CAV.We analyze some key enabling technologies of powered CAV,such as selection of propulsion system,design of aerodynamic configuration and trajectory design.Section 1 of the full paper,after much discussion including particularly that of Fig.2 in the full paper,concludes that the powered CAV should adopt rocket engine ...
