在 (工作 )持续时间短暂设备中伴随有燃烧的气体动力模型试验方法的特点(英文)

Methodical features of testing gas dynamic models with combustion in short-duration facilities

对在高焓、持续工作时间短暂设备中进行伴有燃烧过程的气体动力模型的试验方法的特点作了介绍。根据俄罗斯科学院西伯利亚分院理论及应用研究所组织这种试验工作所积累的经验 ,描述了解决各种各类与燃烧有关的问题的模型配备 ;在发动机进气道中的推力空气动力特性、压力及热通量的测量结果等等。由此说明试验时间为 50～ 2 0

Methodical features of testing gas dynamic models with combustion in high enthalpy short duration facilities are presented. Based on the experience in organization of this kind of work, which has been accumulated at ITAM SB RAS, the specific features of model arrangements for solution of various problems with combustion, measurement of thrust aerodynamic characteristics, measurement of pressure and heat fluxes in the engine duct, etc., are described. It is shown that hot shot wind tunnels with the test time of 50～200 ms are reliable tools for solving combustion problems.
