本文介绍固体燃料底部排气燃烧空气动力理论及实验研究的若干结果。给出喷射参数、来流M数、模型船尾角、船尾长、排气口直径、模型转速等参数对底排减阻率的影响。提出了一种可用于固体燃料底排条件下的底压解析计算方法。
In this paper, some theoretical and experimental studies on the aerodynamic combustion of exhaust fuels at the bottom of solid fuel are presented. The effects of parameters such as injection parameters, M-number, model aft angle, stern length, exhaust port diameter and model rotation speed on drag reduction of bottom row are given. A calculation method of bottom pressure which can be used for solid fuel bottom row is proposed.
