Adaptation of fixed shaft turboprop engines to business and utility aircraft requires drastic simplification of the control system as compared to transport turboprops. The AiResearch TPE331 engine incorporates a variable low pitch stop controlled thru mechanical linkage to achieve both simplified control and also reverse thrust. Control of the system utilizes a cam cut to match airplane-engine-propeller flight characteristics. Flight testing in aircraft varying from a converted B-26 test bed to slow STOL aircraft was used to verify calculations and develop control system, negative torque system and general engine development.
