Abstract:
A total force nonlinear analog model of the UH-1 helicopter was developed which simulates the entire low speed flight envelope from hover to 60 knots. Classical multiloop control theory was applied to design five levels of automatic stabilization which were used as test variables along the control axis of the test matrix. An integrated display was used which superimposes analog symbology over a terrain image. The basic display format, which had been used successfully in flight tests, was modified to provide four levels of display augmentation. These four levels were used as test variables along the display axis of the test matrix. Four helicopter test pilots acted as test subjectes and furnished pilot ratings in each cell of the test matrix. In each cell the subject was required to fly the same prescribed flight profile involving a low level decelerating approach to a hover. The data was evaluated based on significant differences among the test cells, and conclusions were drawn concerning the nature of the control and display augmentation most beneficial to the pilot.
