AIRESEARCH MODEL GTCP100-52-1 POWERPLANT CALIBRATION AND EXTREME TEMPERATURE STARTING TESTS.

Abstract

Powerplant calibrations, including JP-5R fuel consumption determinations, were conducted at compressor inlet air temperatures of 3, 58, and 130F at 100 percent speed using shaft and compressed air loadings. Output is acceptable. Fuel consumption was determined also during no-load operation at various steady state speeds at compressor inlet air temperatures of -22F to 130F. Starting tests were conducted at test temperatures of -32F to +125F using JP-4R and JP-5R fuels and 24-volt 36-ampere-hour batteries. Starting was unsatisfactory at low temperatures due to exhaust flaming, excessive turbine out temperatures and unstable operation. It was improved by reducing fuel flow, using a higher capacity electrical power supply and employing warm fuel. Operation of the fuel metering control and the bleed air load valve is unsatisfactory at low temperatures. Improved turbine section durability is required. (Author)
