Evolving Trends in the Structural Optimization of Aircraft Gas Turbine Engines
Brian Cottrell, Chief Engineer of Structures, Honeywell Aerospace
The history of aircraft gas turbine engine design generally has not included significant optimization of the structural layout of engines. This optimization gap has been driven by the pace of engine layout during the concept development phase and by the extreme complexity of the problem. Therefore the initial selection of the structural system concept has tended to be anchored in experience and in simple parametric trade studies seeking to provide a sound configuration from the perspectives of strength, weight, cost, and modularity.
