STUDY OF AUTOMATIC CONTROL SYSTEMS FOR HELICOPTERS

Abstract

The foundations were developed for the analytical determination of automatic control system design criteria. These foundations consist primarily of the theoretical equations describing (1) the transient motion of a hovering, single-rotor helicopter with rotor rpm degree of freedom, and (2) the dynamical characteristics of reciprocating and single-spool turbo-prop engine types. In addition, the mechanization of the control system transfer function has been investigated from the viewpoint of incorporating in the dynamical analysis the characteristics of high-performance components requiring a minimum of additional development. Also discussed are several topics remaining under investigation or otherwise not completed. These include the study of forward-flight transient motion, the initial phases of the complete closed-loop control study, and the REAC study of rotor rpm control in hovering for the case of the turbo-prop engine.
