Abstract:

A laboratory Tilt Rotor Flying Machine TROFM is designed and built for the purpose of conducting an experimental study of the effects of command systems on human pilot behavior. The aircraft is mounted on a two-axis pivot stand which gives the fuselage 2 degrees of freedom pitch and yaw. Analytical models are derived using Lagrangian and Newtonian techniques. Identification of the aircraft characteristics is based on a nonparametric Discrete Fourier Transform technique and a maximum likelihood parameter estimation scheme. Attitude command, rate command and unaugmented systems are designed and implemented in real time using a digital computer. An investigation of the effects of command systems, displays and tasks on human pilot behavior is conducted. Pilot and pilot-vehicle describing functions are obtained from time histories of dynamic tracking tasks where the pilot attempts to track a random appearing input. Correlations between Cooper-Harper ratings and quantitative descriptions of pilot behavior are made. The experimental results compare favorably to the classical theory of man-machine system dynamics which is based on the cross-over model. The results of this study indicate that desirable controlled elements in man-machine systems have the characteristics of a simple tracker.
