Integrated Value Engineering - adapted approach to assess different concepts of a jet engine

Abstract

A jet engine is defined by several system properties like weight, production costs or the specific fuel consumption which all play a significant role in the lifecycle costs of an airplane. These system properties can be converted into each other. With rising fuel costs, the reduction of the specific fuel consumption is a key focus in the development of new jet engines. In this work, the view of specific fuel consumption in the development was adapted into a new structure based cost management approach called Integrated Value Engineering (IVE). The idea of this work was to assess newly generated solutions for an interface of two jet engine subsystems in terms of several system properties, which influence the lifecycle costs of the system. Therewith the approach supports industry in the assessment of alternative concepts and conceptual decisions.
