FINAL TECHNICAL REPORT: AUTOMATIC GUIDANCE FOR VTOL AIRCRAFT

A simple perturbation feedback scheme is developed for automatic guidance of a VTOL aircraft with a velocity-command flight control system. By neglecting the delay required to attain a commanded velocity and by using ground range to touchdown rather than time as the independent variable, a reduced model having two state variables-altitude and crossrange-and three control variables-components of commanded velocity-was obtained. The performance of the guidance concept was evaluated by means of a six-degree-of-freedom digital simulation of the NASA/LaRC YHC-1A tandem rotor helicopter with the NASA/ERC velocity-command flight control system.
