摘要:
针对边界层转捩探测飞行试验需求,开展飞行条件下的红外热像转捩探测方法研究。通过发射率、辐射入射角及被测件与背景环境的温度差等主要影响因素分析,实施被测件表面处理、红外光路调整、日照辐射及被测件内部加热等措施,以试飞方法、数据处理方法和准度考核构建了一套转捩探测试飞应用方法。开展真实飞行试验,针对干净机翼上表面转捩位置测量进行技术验证,飞行高度Hp=6~7 km,飞行马赫数M=0.55~0.65。试验结果表明,该技术实用可靠,可为后续层流机翼或翼套气动力飞行试验提供参考。
Abstract:
For the boundary layer transition detection method using IR technique in flight test, the main factors of IR technique were analyzed, including radiation incidence angle, emissivity of wing skin, temperature difference between wing and air. Lots of work had been done such as spray inferior smooth paint, adjustment of optical path, sun radiation, internal heated surface and so on. The measurement technique was designed based on the flight test method, data processing method and criterion for determining the transition. This technique was verified in a real flight test environment when the flight altitude was in the range of 6–7 km, and the Mach number of flight in the range of 0.55–0.65. The results indicate that this technique is practical and reliable and is useful for flight test of laminar wing/glove.
