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.
