介绍了一种基于微分载荷模型的飞行载荷辨识方法。根据实测载荷与飞行参数之间存在的相关性,利用输出误差法对平尾微分载荷模型进行了辨识,得到了飞行状态下平尾载荷的计算模型。同时得到了适合于飞行载荷辨识的一种方法,该方法可以研究飞机的不同操纵规律对结构载荷的影响,具有较高的精度,可行有效。
A method of flight load identification based on differential load model is introduced. According to the correlation between the measured load and the flight parameters, the output error method is used to identify the end-of-flight differential load model, and the calculation model of the end-of-flight load under the flight condition is obtained. At the same time, a method suitable for the identification of flight loads is obtained. The method can study the influence of different handling laws of aircraft on the structural loads, and has high precision and is feasible and effective.
