摘要: 介绍了国内外预测航天飞机气动加热的工程计算方法.给出了轴对称、非轴对称和机翼前缘等各种外形驻点热流密度的计算,分析和比较了平板、锥体的层流和湍流热流密度计算的各种方法,概述了航天飞机迎风面中心线和离开中心线横向热流密度的计算.计算结果表明,本文方法用在航天飞机气动热环境初步设计中比较简单并且有足够精度.

Abstract: Approximate methods for calculating aerodynamic heating rates on space shuttles are discussed.Various methods are given for predicting the heating rate at axisymmetric stagnation points,general three dimensional stagnationpoints and the leading edge stagnation point of wings.Numerous laminar and turbulent heating techniques for flat plates and cones are analyzed and compared.A brief review of some methods is presented to predict heating rate for winward centerline and lateral direction off the symmetry plane.The results show that the methods are simpler and can guarantee enought precision for predicting aerodynamic heating environment of space shuttles.
