As of the date of this writing, the nation’s first aviation gas turbine in electric utiltiy service has been in operation over 500 hr with 176 startups for “on-line” operation, of which 52 have been automatic. The average startup time has been 139 sec from pushbutton actuation to full-load operation including all time steps for the operational checks designed into the starting sequence. Operation has been satisfactory and the results of the first “hot-section” inspection (after 500 hr) were excellent, showing practically no wear, erosion or corrosion of combustion chambers, nozzles, or buckets. No maintenance was required for return to full operation.
