AC Generating System for Executive Aircraft

This paper describes an ac generating system designed for a twin jet executive aircraft. The system employs two variable frequency 9/21 kva generators to supply power for aircraft surface heating, fuel pumps, trim motor, and instruments. The system is unique in private executive aircraft in that it is automatic and employs static circuitry for the control and the conversion of variable frequency power to 400 cps constant frequency voltage for aircraft instruments.
