Dynamic test techniques - Concepts and practices

An initial investigation of dynamic flight test analysis techniques indicated that a strict, comprehensive force-moment accounting system would be necessary. An implementation of the longitudinal force-moment accounting system provided excellent results in accounting for small lift/drag and tail deflection changes. Attention is given to gross thrust calculation, instrumentation, maneuvers, and aspects of data correlation. The results of the studies demonstrate that it is possible to generate a lift/drag model which is capable of predicting performance from nearly any maneuver.
