摘　　要：针对电传运输类飞机气动模型试飞校准与验证工作中,试飞数据的高相关性导致的无法有效获取气动模型参数的问题,提出了一种通过优化设计试飞动作与试验状态,隔离相关性高的气动模型影响因素,逐步实现对气动模型参数试飞校准的方法。试飞验证结果表明,该试飞方法可有效支持气动模型试飞校准工作,且校准后的气动模型满足CCAR-60客观测试的容差要求。To solve the problem of being unable to obtain the parameters of the aircraft aerodynamics model during calibration and verification flight test due to high correlation of flight test data,a flight test calibration method is raised to gradually realize the flight test calibration by optimizing the flight test actions and test conditions,isolating the high-correlated aerodynamics model influencing factors. Flight test verification results show that the test method can effectively support aerodynamic model test calibration,and the corrected aerodynamics model meets the tolerance requirements for objective test of CCAR-60.
