Gas Turbine Engine Analog Simulation for Acceleration Sensing Fuel Control Studies 630287
The study of an acceleration sensing fuel control system for gas turbine engines using a small analog computer is presented. The transfer function technique is utilized in simulating the system which permitted a study of the system performance using a minimum of computer components. An actual engine was run using an electrical analog of the control developed on the computer. A system stability map (plot of maximum stable proportional gain versus maximum stable integral gain) is presented comparing calculated, computer, and actual engine results. The advantages of using the analog computer for control system analysis are illustrated.
