摘      要：The overall thermodynamic model of an ultra micro turbine engine has been established and applied in different situations in this tiny engine where heat transfer is dominant. The aerothermal conditions of the flow were calculated and analyzed. A corresponding calculation software (hot button software) was developed. The first results show that the non-adiabatic operation of the turbomachines leads to a strong penalty in performances. The dramatic influence of the compressor and turbine efficiency is confirmed in a non-adiabatic operation. A better knowledge of heat transfer coefficients at low Reynolds numbers in different components of the micro turbine has to be obtained to refine the results of this study.
