... MEMS gas turbine engine.ENGINE DESIGN TRADES, COMPONENT INTEGRATION, AND DESIGN EVOLUTION Gas turbine engines are more than a set of components bolted together. Rather, a successful gas turbine ... gas turbine engines – one that enables gas turbines with diam-eters of millimeters rather than meters, with airfoil dimensions in microns rather than millimeters. These shirt-button-sized gas ... 2:1 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...
