A Preliminary Engine Design Process for an Affordable Capability

Abstract

This paper will examine the military engine preliminary design process used by Rolls-Royce to support capability vs. cost' trades conducted at the weapon system level. The engine is a major sub-system of all air vehicle assets making up a force mix. Changes in the engine capability, e.g. thrust/weight and specific fuel consumption, can be tracked through to air-vehicle performance and ultimately to the force mix capability. In the same manner these changes will impact on the engine and air-vehicle life cycle costs and hence the total system costs. These trades are vitally important in establishing the optimum affordable system solution early in the design and development cycle thereby preventing the need for expensive changes during full-scale development. Rolls-Royce has developed a preliminary design process to quickly assess engine capability incurred costs. The process has evolved to enable the rapid definition of an engine including performance attributes and Through Life Costs (TLC's).
