摘要
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。
This report presents a method of flight load identification based on differential load model. Ac- cording to relativity between the flight measured load and flight parameters, the horizontal tail differential load model has been identified by means of output error method; then a calculated model for horizontal tail load in flight condition has been established. A method suitable for flight load identification is ob- tained, which could be used to study the influence of different operating rules on structural load. It is of high accuracy and effective.
