Aircraft Engine Blade-Out Dynamics

A primary problem in the design of aircraft gas turbine engine internal and support structures is the accurate simulation of the fan blade-out event and the subsequent windmilling of the engine. Reliable simulations of the blade-out event are required to ensure structural integrity during flight as well as to guarantee successful blade-out certification testing. A model and procedure has been developed which successfully predicts the key physical behavior of a generic engine structural dynamics. The key procedures and modeling techniques for this application are given.
