... to 4:1 and turbine inlet temperatures of 1200-1600 K. The projected performance of these engines are on a par with gas turbines of the 1940’s. The thermodynamics of MEMS gas turbines are the ... engines, however, the combination of harsh environment, high frequency response, high accuracy, and high reliability means that sensors and actuators for MEMS-scale gas turbines must be specically ... while the Otto [8], Diesel, and Stirling cycles are unsteady engines. The Brayton power cycle (gas turbine) is superior based on consider-ations of power density, simplicity of fabrication, ease...
