乘波飞行器构型方法研究

Research on waverider configuration method

  • 摘要:高超声速飞行中,随着马赫数的升高,波阻和摩阻增加,就会形成升阻比``屏障'',而乘波飞行器构型是克服这一升阻比屏障的有效方法. 本文提出了一种变楔角楔/椭圆锥乘波体构型方法,并基于前体/进气道一体化设计思想,生成了高超声速乘波飞行器构型. 经数值计算与实验验证,与传统锥形流场生成的乘波体相比,该方法生成的乘波体不仅具有高升阻比,而且能为发动机提供所需的高温高压均匀来流.

    Abstract:In hypersonic flow, as the increase of Mach number, thewave drag and friction drag also enlarge, and this will form a hysonic L/D``barrier''. But waverider can efficiently overcome this ``barrier''. Inthis paper we develop a wedge-elliptical cone waverider configurationmethod, study on front body-scramjet engine integration design, and create ahypersonic waverider. In terms of numerical result and wind test data, it isdifferent from traditional waveriders that this waverider can offer not onlyhigh L/D ratio, but also the uniform flow field with high temperature andhigh press which is requireed by scramjet engine.
