The performance sensitivity of a two-shaft automotive gas turbine engine to changes in component performance and changes to cycle operating parameters was examined. The engine tested was the Chrysler Upgraded engine developed under a U.S. Department of Energy contract. A test of one Upgraded engine at the NASA Lewis Research Center was one aspect of a corrective action program to remedy a power shortfall in the early development engines. To support that test, the engine was modeled for use with a computer performance prediction code. Performance sensitivity to turbo machinery efficiencies, regenerator effectiveness and pressure drop, parasitic losses, and flow and heat leaks was examined.
