Aircraft Engine Simulation Project for Undergraduate Propulsion Course

Abstract

This paper describes a jet engine simulation project assigned to mechanical engineering students in a senior level course in aircraft propulsion systems. The project introduces the students to the methods of engine system analysis and design based on computer simulation. The project statement provides the students with the design point operating characteristics such as engine inlet conditions, pressure ratios, and static thrust developed, which are necessary to develop a design point thermodynamic model. After topics in cycle analysis and engine component performance are introduced the students can develop the system of equations necessary to model the engine system and use this model to predict the off-design performance (speed, thrust, efficiency, etc.) of the engine. Off-design conditions resulting from changes in throttle setting, aircraft speed, altitude, and environmental conditions are considered.

Mathcad Functions For The Thermodynamic Properties Of Moist Air, Ammonia, Propane, And R 22

“…While developed for a two-course sequence in undergraduate thermodynamics, the MathCAD function sets are useful for many other engineering courses. The functions presented in this paper and the thermodynamic functions presented in previous works have been found to be very useful in courses such as internal combustion engines, propulsion, combustion, compressible flow, and heating ventilating and air conditioning [9,10,11,12].…”
