A Method for Estimating the Flying-quality of Airplane with Complicated Systems

ZHAO Jian-wei,ZHOU Zhou,ZOU Ding-yu,GONG Xi-ying(Northwestern Polytechnical University,Xi'an Shanxi 710072,China)  
The flying-quality of the airplane plays an important part in estimating the aircraft,so how to estimate is also very crucial.With the system becomes more complicated,traditional methods can't do it well in some situations. This paper studies a new estimating method,by seeking a simple system equivalent to the complicated system and using the majorized function to calculate the equivalent parameters with which the quality of the original system can be assessed.At last the equivalent-quality parameters are computed and the flying quality of a airplane is assessed using the MIL-F-8785C.This method proves to be simple and practical.
