ABSTRACT
The Massachusetts Institute of Technology Departrnent of Mechanical Engineering teaches
thermodynamics and fluid mechanics through a pair of classes, Thermal Fluids Engineer•
ing I & II. The purpose of this project was to design and fabricate a gas-turbine engine
for demonstration use in these two classes. The engine was built from an automobile tur•
bocharger with bustion chamber connected between pressor and turbine. Pres•
sure and temperature sensors at different points of the engine cycle allow students to monitor
the performance of the individual ponents and plete engine cycle.
