Parameter identification based helicopter attitude agility flight test technology

This paper presented a research of the helicopter attitude agility by means of parameter identification.Based on different specifications, test methods and response types, the helicopter attitude agility response in the second-order form was obtained with the method of parameter identification.The assessment indexes of helicopter attitude agility could be obtained more accurately and quickly through parameter identification.Finally, combined with the results of the helicopter flight test, the related conclusions were analyzed, which provides a guidance for the subsequent helicopter flight quality test.
