高超声速飞行器操稳性能分析

Control and stability of hypersonic cruise vehicle

以静稳定性衡量稳定性能,以可用过载衡量机动性,给出了高超声速飞行器操稳性能的计算方法。并以高超声速飞行器基准外形为例,计算了其在不同马赫数下的操稳性能,分析了操稳性能随马赫数的变化关系,为高超声速飞行器概念设计阶段的优化设计提供了操稳性能优化指标。

Control and stability are the most important indexes of a flight vehicle in the shape optimum design. As guidance and control systems have not involved in at a primary and conception design phase, the dynamic stability and maneuverability could not be analyzed, optimum design will take static stability and maneuverability as indexex. This paper provides the control and stability computation method for a hypersonic cruise vehicle. And it takes a reference the shape of the hypersonic cruise vehicle as an example, computes its control and stability in different Mach number, and analyzes its change as Mach number increases, which provides control and stability optimum indexes for the conception design of the hypersonic cruise vehicle.
