Book Description
An experimental investigation was made to determine whether the maximum sulfur content of 0.4 weight per cent, currently allowed in grade JP-5 aviation turbine fuel, is a safe level for protection of the super-alloys used in high performance engines when operated in a marine environment. A second phase dealt with the effect of fuel molecular structure and volatility on the total radiant energy from combustor flames, which by contributing to the operating temperature of hot section components limits aircraft turbine engine power and durability.

EFFECT OF JP-5 SULFUR CONTENT AND SEA WATER INGESTION ON HOT GAS CORROSION OF SUPER ALLOYS.

Pages : 76
Book Description
An experimental investigation was conducted to determine whether the maximum sulfur content of 0.4 weight per cent, currently allowed in grade JP-5 aviation turbine fuel, is a safe level for the protection of turbine blade alloys used in high performance engines. Specimens of two nickel-base alloys (Inconel 713C and Sierra Metal 200) were exposed to vitiated air from the Phillips 2-inch combustor (56 air-fuel ratio) at high temperature (2,000 degrees Fahrenheit), high pressure (15 atmospheres), and high velocity (500 feet per second) during a five-hour cyclic test (55 minutes fuel-on and 5 minutes fuel- off). A statistically designed test program was used to evaluate the effect of three sulfur concentration levels in the fuel (0.0002, 0.040, and 0.40 weight per cent) at three sea salt concentration levels in the air (zero, 1.50, and 15. 0 parts per million), and also any sulfur x sea salt interaction. The significance of test specimen metal losses and changes in tensile properties was established by analyses of variance, made at a confidence level of 95 per cent.
