Preliminary PERFORMANCE ANALYSIS OF GAS TURBINE POWERPLANTS 480225
THIS paper outlines a method for obtaining the performance of a gas turbine powerplant with a variable exhaust nozzle, based upon a graphical process for matching the turbine and compressor.
The method is general in that it may be employed for all operating points at any altitude and speed.
The deviations from the ideal static sea-level operation are determined on an h-s diagram from increments of entropy produced by pressure losses through the system and by pressure gains due to velocity.
