Using Jet Engine Simulator in Propulsion Education

Undergraduate education in jet propulsion can benefit from a modern real-engine simulator. The traditional lecture/laboratory course in propulsion continues to emphasize fundamental aerothermodynamics and often includes a propulsion laboratory that tests small engines (e.g., micro-turbojet engines) mounted on a thrust stand. Modern engine simulators, as virtual test bench, offer new tools and capabilities that help students learn the fundamentals as well as jet engine response to dynamic throttle setting. Geared, high-bypass ratio, two-spool turbofan engines can be simulated in a virtual test bench from takeoff to cruise at different altitudes and Mach numbers. The simulator employs an electric start, a real FADEC (Full Authority Digital Electronic Control) system and system communication that is coupled to a real power lever. The tools that are embedded in the virtual test bench allows for various studies, including control systems, comparing open-loop and closed-loop control. The integration of a state-of-the-art engine simulator in the jet propulsion course at the University of Kansas, Aerospace Engineering shows enhanced student engagement and learning.
