Fast design optimization of jet engine structural mass and specific fuel consumption.
Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering , 225, (10), . (doi:10.1177/0954410011409524).
With the increasing demands placed on modern jet engine performance and reliability, there comes the necessity for efficient optimization tools that engineers can readily utilize on their desks. This article discusses the application of a multi-objective optimization tool to the design process for a key structural element in the highly respected Rolls–Royce Trent jet engine series. The ability of this structure to maintain tightly controlled blade to casing tip clearances plays a significant role in maintaining the fuel efficiency of the engine. The design tool described here has been implemented on a conventional desktop computer and allows efficient trade-off analysis of structural mass versus specific fuel consumption for four-load cases
