航空发动机自适应建模技术研究

ADAPTIVE MODELLING TECHNIQUE FOR AEROENGINE

本文介绍了航空发动机自适应建模方法，并根据某型发动机高空试验实测数据对该型发动机数学模型及其部件特性进行了自适应修正，修正后的发动机模型计算结果与实测结果十分吻合。

An adaptive method for aeroengine modelling is introduced on the basis of an established original model.A weighing function and a series of correction factors are adopted.The value of the weighing function will be minimized when the correction factors are optimized so that the adaptive correction of the model and the part characteristics is accomplished.In order to validate the feasibility of this method,the test data of a given engine are used to revise its mathematical model and the part characteristics with the method.
