Abstract:

Engine cycle studies in which compressor component performance anticipated in 1973 was used were conducted to select operating conditions for a 3-pound-per-second front-drive gas turbine optimized for minimum specific fuel consumption SFC at 60-percent power. Fixed turbine geometry was assumed. Preliminary matching studies of seven combinations of axial and centrifugal compressor stages were conducted to accomplish cycle requirements for 20-, 30-, 60, and 100-percent-power operation. The compressor type selected--two axial stages employing variable inlet guide vanes plus one centrifugal stage--was configured in a preliminary design for application in a preliminary engine layout.
