The "Common Core" from which a family of turboshaft, turboprop, and turbofan engines can be derived has been the goal of engine companies for many years. The advantages in terms of development synergy, reduced cost, and in-service experience / support / maintenance / commonality are well known and extremely desirable. This paper provides an overview of the engine family in terms of background, engine configurations/technologies, applications and development approach / schedules, lessons learned and future plans.
