Analysis of VTOL Handling Qualities Requirements. Part 2. Lateral-Directional Hover and Transition

Abstract

Analyses of available handling qualities data were performed to determine lateral/directional dynamic requirements for VTOL aircraft in hover and low speed flight. The basis for this treatment is an examination of the pilot/vehicle as a closed-loop servo system. The quasi-linear pilot describing function is applied. The results of the studies suggest that the primary factors identifying satisfactory and unacceptable hover mode dynamic features are related to the closed-loop deficiencies. Detailed consideration is made of the control task and piloting functions in transition flight. The results of this generic appraisal are evoked to confirm and justify preliminary lateral/ directional requirement for control in transition.
