Franklin J.A. V/STOL Dynamics, Control, and Flying Qualities

NASA/TP-2000-209591. October 2000. National Aeronautics and Space Administration (NACA). Ames Research Center. Moffett Field, California 94035-1000. — 198 p.This publication presents material that constituted the lectures presented by the author as part of course AA 234, Dynamics, Control, and Flying Qualities of V/STOL Aircraft that was taught in the Department of Aeronautics and Astronautics at Stanford University. It covers representative operations of vertical and short takeoff and landing (V/STOL) aircraft, a discussion of the pilot's strategy in controlling these aircraft, the equations of motion pertinent to V/STOL tasks, and their application in the analysis of longitudinal and lateral-directional control in hover and forward flight. Following that development, which applies to the characteristics of the basic airframe and propulsion system, the text concludes with a discussion of the contributions of control augmentation in specific flight tasks and of the integration of modern electronic displays with these controls.NomenclatureRepresentative operations of V/STOL aircraft
