Abstract

A procedure for calculating contact loads on a dovetail surface for given engine performance parameters such as speed and temperature is described. The procedure requires a small number of predetermined calibrating finite element analyses to obtain empirical constants. Verification is provided by detailed finite element analyses. Contact loads can be calculated for an entire mission history in near real-time. The contact load histories could be used to calculate local stress necessary for fatigue life prediction.
