摘要: 针对高超声速飞行器地面防热试验高精度总焓测量需求，研制了一种带热防护罩的稳态焓探针。基于能量平衡原理设计了稳态焓探针测量系统，采用有限元方法分析了焓探针采样管长度、壁厚以及冷却水流向、流量对焓值测量误差的影响，优化设计了焓探针的隔热结构和水气流量。在电弧加热器流场中开展了验证试验，结果表明：该稳态焓探针参数设计合理且隔热结构性能良好，重复性精度优于2.6%，与驻点热流Fay-Riddell法比较，最大偏差为13.0%。Abstract: For high precision test requirements of the total enthalpy in the ground thermal shielding test of hypersonic vehicles, a kind of steady enthalpy probe with heat shield was developed. The enthalpy probe test system was designed based on the energy balance principle. And the influence of the sampling tube and the cooling water on the enthalpy value was analyzed by FEM. Then the heat insulating structure, water mass flow and gas mass flow were designed and optimized. Finally, the verification test was implemented in the arc heater flow field. The test results show that the design of the enthalpy probe parameter is reasonable, the enthalpy probe structure has a good insulating performance, the repeatability accuracy of the enthalpy probe is better than 2.6%, and the deviation of measurement values of the enthalpy probe and the Fay-Riddell method is less than 13.0%.
