调整试飞阶段的某型飞机气动参数辨识实现方法

An Aerodynamic Parameter Identification Approach for Regulator Fly of Certain Airplane

针对飞机调整试飞阶段质量特性数据变化较大的特点,以及飞行测试的限制,提出了一种气动参数辨识实现方法,该方法包括飞机质量特性数据的获得、飞行测量数据的重建等辨识数据的完善和成熟的辨识算法。并以某型飞机为例进行了纵向气动参数辨识,计算结果合理,表明该方法有效,具有很好的工程应用价值。

The mass and inertia of airplane in regulator fly always change greatly, in order to solve this problem and the limit of flight test measure, an approach for aerodynamic parameter identification is given. The approach includes how to get the mass and inertia of airplane, how to reconstruct the flight test data and an effective identification arithmetic. The longitudinal aerodynamic parameters of certain airplane are identified and the results are reasonable. This indicate that this approach is useful and of great value in practice.
