    摘要:

    激光等离子体减阻技术对于高超声速飞行器减阻隔热和提高飞行器性能具有重要意义。介绍了脉冲激光减阻研究的数值计算模型和实验研究方法;总结了激光等离子体减阻机理;讨论了入射激光能量、能量沉积位置和流场马赫数等关键参数对减阻性能的影响规律。针对目前研究现状,提出通过等离子体热核建立关键参数与激光减阻效果间联系的建议。

    Abstract:

    Laser plasma drag reduction technology is of great significance for hypersonic aircraft drag reduction and thermal insulation and improves aircraft performance.The numerical calculation model and experimental research method of pulsed laser drag reduction research are introduced; The mechanism of laser-plasma drag reduction is summarized; The influence of key parameters such as incident laser energy,energy deposition position,and flow field Mach number on drag reduction performance is discussed.Given the current research status,suggestions are put forward to establish the relationship between the key parameters of plasma hot core and the effect of laser drag reduction.
