ENGINE DESIGN OBJECTIVES
All aircraft represent an investment of money for an anticipated profit. It is evident that commercial aircraft are built and bought to earn a monetary return on an investment. Although the revenue derived from investment is less tangible for many military aircraft, these too are expected to provide
some kind of an identifiable payoff that can be expressed in terms of money. An appropriate economic analysis, therefore, always precedes a decision to design, develop, and manufacture a new or a modified type of aircraft engine. The costs considered include all of the expenses of acquiring
and servicing the aircraft involved as well as the engine.
A necessary part of the economic study is the execution of a preliminary design of the proposed vehicle and its powerplant. Chapter 3 of this volume as well as Ref. 3 review the many details that must be considered during such a preliminary design.
