Abstract

A historical survey of the development and future trends in aero engine design and performance are given. Emphasis is placed on the achievement of low cost of ownership through high fuel efficiency. Simple basic principles controlling the conceptual design and performance are described. The choice of engine thermodynamic cycle is discussed with emphasis on the civil transport engine. The differing requirements of the military aircraft engine are briefly stated. Short-term possibilities for improved performance and longer term speculative proposals are made. Advanced technology requirements in materials, mechanical design and aerodynamics are outlined.
