Study on given rotating speed of some turbofan engine based on data fusion

针对试验室无法设计实现机械连动装置确定某涡扇发动机给定转速,在研究分析某涡扇发动机转速控制系统的工作机理和影响该型发动机给定转速因素的基础上,提出了一种确定该型发动机给定转速的数据融合算法。通过对基于数据融合确定的给定转速试验,结果表明:提出的数据融合算法结构简单、计算简便、计算结果的相对误差都在1%以内,将其用于确定某涡扇发动机的给定转速是完全可行的。

Because given rotating speed of some turbofan engine can be known not through setting up mechanical devices, a data fusion arithmetic is presented to make certain of given rotating speed on the base of studying the working principle of some turbofan engine rotating speed control system and the factor of affecting given rotating speed. Through experiment, the results show that the structure of the presented data fusion arithmetic is single, its calculation is advantageous, its relative errors are in 1%, and the presented data fusion arithmetic applying for calculating the given rotating speed of some turbofan engine is effective.
