Advanced Engine Control System Study
Abstract
The report presents the results of a program conducted to design and evaluate an advanced engine control system for a small (2 to 5 pounds per second airflow) turboshaft engine. The objective of this program was to evaluate the feasibility of a unique engine control system consisting of closed-loop turbine- inlet-temperature limiting, electronic computation and either of two novel fuel metering systems. Control mode logic and dynamics were analyzed using computer simulation techniques. Control computer logic and circuitry were established, and all elements of the control system were designed. It was concluded that a miniaturized advanced control system, weighing 6 to 9 pounds (including pump), is feasible with either of two fuel metering systems and with either analog or digital electronic computation.
