摘要

乘波构型高超声速飞行器布局具有高升阻比的优点，但有效容积低和尖锐前缘使其在实际工程应用中受限。为弥补乘波构型飞行器有效容积低的不足，提出了一种乘波构型上表面参数化设计方法，同时开展了前缘钝化研究，采用增加前缘材料的方法进行钝化。分析了上表面不同设计参数对乘波构型飞行器容积率和气动性能的影响，研究了飞行器气动特性随迎角和马赫数的变化规律。计算结果表明，钝化后的经给定容积上表面设计的乘波构型有效提升了有效容积及容积率，并且仍能保持良好的乘波特性。数值仿真结果表明容积效率和气动性能是相互矛盾的关系，需要根据实际情况进行权衡。对于给定有效容积上表面设计的乘波构型高超声速飞行器，适合在一定范围的正迎角下飞行，并且能在较大的马赫数范围内保持优良的气动特性。研究可为提升高超声速乘波飞行器有效容积提供参考，提高了乘波构型飞行器的工程应用性。

Abstract

Waverider is an effective configuration for hypersonic aerocraft with high lift-to-drag ratios. But its insufficient effective volume and sharp leading edge lead to difficulties in the engineering application of waverider. To expand effective volume of waveriders

a parametric upper surface design method was created and discussed. The blunt method was analyzed in this work

and the influence of different design parameters of upper surface design on effective volume and aerodynamic performance were discussed. The influence of attack angle and Mach number on the aerodynamic characteristics of upper surface design with the consideration of practical application was also analyzed. The results show that the design method can expand volume effectively. The analysis of flow field indicated that the blunted waverider with upper surface design can maintain the "wave rider" characteristic well. The relationship between the effective volume and the aerodynamic performance is inconsistent

which needs to be considered on the basis of different practical situations. The upper surface design waverider performed well at positive attack angle within limits and Mach numbers in wide range. A new method of upper surface design was proposed and studied about relative scientific problems. Based on the results

some useful advice can be obtained for expanding effective volume of waverider

which may improve waverider from an academic concept into a practical engineering application.
