摘　　要：高超声速设备的试验能力对高超声速技术的发展至关重要,目前受制于加热器技术,常规高超声速风洞能够模拟的最高Mach数不超过10。电弧加热器是高焓风洞的重要设备,将电弧加热高焓风洞用于常规气动力试验,为提高试验模拟Mach数开辟了新的方向。介绍了中国航天空气动力技术研究院1.2 m电弧加热高焓风洞进行的AGARD-B标模试验,通过多次标模测力试验结果的标准差,检验了风洞试验数据的重复性和流场稳定性,通过和国内外已有风洞试验数据的对比分析,检验了风洞试验数据的准确性,为后续该电弧加热高焓风洞承接Mach数10的气动力试验提供强有力的技术支撑。The test capacity of hypersonic equipment is crucial to the development of hypersonic technology.However,the maximum Mach number simulated by conventional hypersonic wind tunnel is less than 10 currently due to the insufficient heater capacity.Considering the outstanding performance of arc heater in high-enthalpy wind tunnel,applying arc-heated high-enthalpy wind tunnel for conventional aerodynamic tests makes a breakthrough for increasing test Mach numbers.This paper presented the test of AGARD-B calibration model carried out in the arc-heated high-enthalpy wind tunnel of the China Academy of Aerospace Aerodynamics.The standard deviation of multiple repeated aerodynamic test results verified the self-consistency of test data and proved the stability of flow field.Accuracy of the test data was also certified through comparison and analysis with existing data from both foreign and domestic wind tunnels.This test demonstrated that the arc-heated high-enthalpy wind tunnel is fully capable of conducting aerodynamic tests at Mach 10.
