尾支撑喷流试验技术研究

Investigation of Jet Technology with Sting System

本文以喷流模拟、柱体环形喷管喷流对模型底压影响、以及尾支撑和侧支撑对模型底压影响为基础,从定性、定量得出,用尾支撑作喷流试验,支撑干扰小,可做到既经济又可靠,数据准度较高。

Based on the jet simulation, the effects on base pressure by cylinder annular nozzle jet as well as with side support and sting support, this paper has obtained qualitatively and quantitatively the result that sting support is of less support interference, and it can be economical as well as reliable.At the same time,of higher data accuracy.
