Abstract
The purpose of the work performed under this contract was to conduct a UH-1C model validation analysis. The model was obtained from Government- furnished MOSTAB-C computer data that defined the UH-1C stability and control derivatives at selected flight conditions. The reference data consisted of Government-furnished UH-1C helicopter flight test data. Overall, the MOSTAB-C data represented a fair first approximation to the actual vehicle dynamics. The MOSTAB-C data that was least representative of the actual vehicle response dynamics was the cross-coupling responses.
