导弹弹头再入大气期间,由于气动环境恶劣弹头外形瞬息万变。变化过程是复杂的,是由多种因素引起的。其中一个重要因素是头锥表面附面层的流态。理论分析与试验结果指出,头锥表面附面层为全层流时,驻点加热率最高,烧蚀率最大。当头锥被充分发展的湍流附面 During the reentry of the missile warhead into the atmosphere, the warhead shape is rapidly changing due to the poor aerodynamic environment. The process of change is complex and is caused by many factors. One of the most important factors is the fluidity of the surface of the head cone. Theoretical analysis and experimental results show that when the surface layer of the head cone is full laminar flow, the stagnation point heating rate is the highest and the ablation rate is the largest. When the nose cone is fully developed turbulent surface
