Automotive Gas Turbine Power Performance Analysis Code System

SUMMARY AND CONCLUSIONSThe current implementation of the "OpenCycle Version" of the NASA LeRC BRMAPSCode can be used to run performance comparisonsfor automotive gas turbine/hybrid engines at steadystate opera-ting conditions. The payoff in fuel econ-omy as function of either component improve-ments,or higher turbine inlet temperatures enabled by use ofadvanced materials, can be rapidly ascertained in or-der to guide engine development along a most effi-cient and productive path. Future code enhance-ments incorporating weight, volume, and perhapseven cost models, may enhance this process evenmore dramatically.REFERENCES .. Brandhorst, H.W., Juhasz, A.J., and Jones, B.I.1986.
