I believe that the P&W announcement was for a mid sized turbon fan, with a
very high bypass ratio. Speaking from previous experience, this is likely to
be the PW6000 (mid-thrust-family-engine) with a geared fan and a bypass
ratio of about 15:1. The by-pass ratio guess is based on a previous P&W
effort at developing the Advanced Ducted Propfan.

The fan will be bigger, but the application will probably be an aircraft in
the 100-120 seat range (shrunk A319?), or even a regional jet?

Comments anyone
