PW-Allison Engines with subcontractor Hamilton Standard are designing a Propfan Propulsion System for commercial and military transport aircraft. These companies are targeting for an early 1990's certification of a pusher system for the Douglas MD91X and the Boeing 7J7 airliners. The paper describes the Model 578 Propfan Propulsion System design considerations. Included are discussions on core engine selection, comparing new versus derivative; cycle definition; configuration and installation studies including gear system concepts; and propfan propulsor configurations. Engine selection studies will highlight fuel burn, economic, and acoustic criteria.
