An investigation was conducted in the Cleveland altitude wind tunnel on a turbine operating as an integral part of a turbojet engine. The tests were conducted with four different exhaust-nozzle-outlet areas over a wide range of simulated flight conditions and over the full operable range of engine speeds. The turbine was effectively utilized in the standard installation used during the investigation and a maximum efficiency of 0.875 was obtained.
