With Mitsubishi having selected the PW GTF for their new RJ and Bombardier having done the same for the C Series - both against proposed new engines from GE and RR: neither of which were GTFs, does this mean that the GTF is the way of the future - at least for narrowbodies? If so, where does this leave GE and RR: do they skip a generation and go straight to unducted fans and risk missing out if Airbus and Boeing go for more conventional engine installations on the A320/737 replacements, or do they play geared fan catch-up?
And hasn't the ALF502/LF507 got a geared fan which hasn't been a huge success?
Any equally sad engine enthusiasts got any thoughts?
