Abstract:

The net thrust TME-300, gross thrust TME-300C1, ram drag TME-300-C2 computers were evaluated on a J79-GE-8 engine at simulated flight conditions ranging from static sea level to 50,000 ft, M 1.4. The purpose of these tests was to determine the accuracy of the computers. The TME-300-C2 indicated ram drag was within 1.3 F.S. or 115 lbs of the calculated and the measured ram drags. The TME-300-C1 indicated gross thrust was within 2.5 F.S. 375 lbs of the calculated and the measured thrusts for 81 of the data. The gross thrust computer operated erratically at altitudes below 5,000 ft. For altitudes above 5,000 ft, the computer indicated gross thrust was within 2.0 F.S. 295 lbs. The TME-300 indicated net thrust was within 3.0 F.S. 450 lbs of the calculated and the measured net thrust. The TME-300-C1 gross thrust computer was bench tested and found to malfunction on several occasions. Despite the malfunctions, the computer demonstrated an accuracy of indicating gross thrust to within 1.2 F.S. 180 lbs of the calculated gross thrust. This degree of accuracy was not attained during the engine tests. Author
