A jet engine's efficiency is strongly dependent upon clearances between rotating blades and the corresponding stationary gas-path seals. Analytical studies to examine the effects of various flight cycle loads on powerplant clearances suggest that rotor/seal interferences may contribute to the short/term performance determination exhibited by all high bypass jet propulsion systems. In prior analytical studies, flight cycle loads were treated in a quasi-steady, static manner, even though some flight cycle loadings are decidedly dynamic in nature. Gust encounters and aircraft landings are classical examples of dynamic flight loads found in typical airline service. An analytical technique for predicting the effects of aircraft dynamic light loads on engine performance was developed and is described herein. (Wassmann)
