I wasn't suggesting a bigger 175 was the answer, just speculating as to what AH might
think would be the answer.
Fundamental problem in the upper end of the rotary game is its always a derivative or an evolution of a mil platform. The civil "large" sector just doesn't justify a clean sheet, unique design from an investment payback perspective.
Look at how long it took SIK to get the S92 selling and even that was based on the Black Hawk. In reality there have never really have been any true "clean sheet" designs since WW2 and in some respects the design issues for rotary demand some form of prior sub-system operational data (versus FW where a theory/modelled approach works better) even if, ironically, it ultimately unravels the assumptions. Vibration and load transmission behaviour is unfortunately not reliably transferred or scaled.
