Abstract
Two F100-PW-100 prototype afterburning turbofan engines were airflow and thrust calibrated in the NASA Lewis Research Center Propulsion Systems Laboratory 4 altitude facility. The engines were calibrated to support flight research at the Dryden Flight Research Center. This report compares the facility performance data for the two engines with an engine performance model, and it provides corrections that can be applied to the model so that it represents the test engines accurately over the flight envelope. Test conditions ranged from Mach numbers of 0.80 to 2.00 and altitudes from 4020 meters to 15,240 meters. Two distortion screens were used to determine the effect of distortion on airflow. Reynolds number effects were also determined. Engine hysteresis is documented, as is an attempt to determine engine degradation. The calibrated engine model had a twice standard deviation accuracy of approximately 1.24 percent for corrected airflow and 2.38 percent for gross thrust.
