Prediction,Evaluation,and Specification of Closed Loop and Multiaxis Flying Qualities.

摘要

A general technology for the prediction, evaluation, and specification of closed loop and multiaxis flying qualities is documented. A comprehensive scheme for the classification of precision piloted tasks is presented, and a nonlinear multiaxis pilot model is described. Demonstrations of the aircraft/pilot/task analysis method are given for a number of precision piloted tasks and aircraft configurations. The analysis method is also applied to a comparison of Gaussian and non-Gaussian (Reeves) turbulence models, and to a study of the effects of control system lags on tracking performance. Piloted flight simulations were performed to validate all pilot model analyses; complete simulation and pilot model data are presented. Specification methods suitable for MIL-F-8785B are suggested in the areas of step target tracking and pilot reserve attention capacity. A computer program embodying the analysis method is available from AFFDL/FGC; a user guide, listing, and sample data set are included in the report. (Author)
