The commercial air transport industry is on the threshold of the Ultra High Bypass (UHB) engine era, which will usher in another leap forward in fuel efficient, low noise gas turbine engines. Anticipation of propulsion system requirements has led to implementation of advanced technology development supporting both the Counter Rotation Propfan (CRP) and the Advanced Ducted Prop (ADP) concepts. The paper will review the advanced cycles for these concepts, definition of critical component technology and the technology readiness programs underway at Pratt & Whitney (P&W).
