Abstract
A STUDY of the operation of aircraft gas turbine powerplants under various atmospheric conditions shows that trends in performance will not always be similar to the trends noted with reciprocating engines.
High humidity will have a negligible effect on performance, but ingested water will automatically increase power in a turbine engine regulated by speed and combustion-temperature controls without a power-limitation device.
Abrasive, erosive, or contaminating matter in the air stream may change blade contours and clearances, decreasing compressor efficiency, engine power, thrust, and overall efficiency.
Several inertia-type separators which should be useful in removing foreign material, especially moisture, from the air stream are described.
