Applying Design-To-Life Cycle Cost Methods During Engine Advanced Development

In order to make better decisions during advanced development of turbine engines, life cycle cost (LCC) methodologies must adequately reflect the impact of engine design decisions on the total system LCC. Two applications of Teledyne CAE's APSICOST Methodology are presented herein. These demonstrate the integrated nature of turbine engine LCC analyses with total aircraft system LCC.

It is recommended that a joint airframe/propulsion/government effort be undertaken to standardize methods for reflecting aircraft system LCC impacts in turbine engine advanced development activities.
