吻切锥乘波机的构型设计与性能研究

以圆锥绕流流场为基础，给定进气道进口曲线运用吻切锥理论生成了不同的乘波机构型，并对乘波机进行了包括升力、粘性阻力、波阻、升阻比、乘波机长度、体积、容积效率等各主要性能指标在内的性能计算，初步确定出了吻切锥乘波机构型和性能的变化规律及其决定性定型参数。计算结果表明：源流场圆锥半锥角、进气道进口高度是乘波机性能的决定性因素；在乘波机容积效率要求较高的设计要求下，粘性阻力占乘波机阻力的主导地位，其初设计过程也必须考虑粘性的影响。乘波机的生成过程和性能计算充分证明了乘波机作为高超声速飞行器和空天飞机外形的三项无与伦比的性能：较高的升阻比、由流场推算乘波机外形的反设计和一体化设计性能。

Osculating-cone waverider configuration design and performance research

The hypersonic flow past a cone were calculated.Waverider configurations were generated by Osculating-Cone in that the inlet curve were given.The primary performance of waverider including lift,friction drag,wave drag,lift-to-drag ratio,length,volume,volumetric efficiency,etc,were calculated.Investigation shows that semivertex angle and the inlet height are the two most important parameters which play important role on the Osculating-Cone waverider performance;the friction drag occupies the predominant position in the drag when the waverider require high volumetric efficiency;the beginning design of waverider must take into account the friction drag.The generation and performance computation of waveriders testify it's incomparable performance as hypersonic vehicle and aerospace plane configurations:high lift-to-drag ratio,the inverse and the integration design.
