SCAT弹头热防护的简化计算方法

A Simplified Calculative Method for Thermal Protection of SCAT Nosetip

本文对自适应发汗冷却（ＳＣＡＴ）弹头的热防护问题作了简化分析，并导得了热防护计算的简化计算公式。对铊，铟，锡和水四种冷却剂的情况，给出了算例。本文导行的公式，计算较简便，可作为弹头热防护设计的一种工程计算方法。这种工程计算方法亦可以用于地模拟实验前的予算。

Simplified analysis for thermal protection of the Self-Contained Adaptive Transpiration (SCAT) nosetip is provided and the simplified calculation formulas of thermal protection are deduced. The calculation examples of thallium, indium, tin and water coolants are given. The deduced formulas in this paper are simple and convenient. An engineering calculation method of nosetip thermal protection design is obtained in this paper. It can be used in prediction before the ground simulation experiment.
