Again. According to the VXX program plan that NAVAIR just awarded, and claimed a cost savings victory on, as far as airframe development goes, whatever is CURRENTLY FAA certified on the S-92 is what they get. ANYTHING else either has to be done as an STC or it goes into the NAVAIR certification realm which opens the aircraft up to the same pitfalls of extensive testing that killed the VH-71 program. Which was where 90% of the cost growth in the VH-71 program developed, test time. (FACT)
L/W: imagine the vibration issues if the UH-60 were 6000 lbs heavier with the same 4 bladed system and blade chord width. That's the challenge. You can only do so much with FG's to null it out. 5th blade and slightly narrower blades are the next step.
The aircraft would live up to expectation and the aircraft Nick Lappos envisioned, IF they developed it as advertised: 5th blade, Upgraded transmission, FBW flight controls.
SAC is selling all they can make right now, helicopter operators are making money with the aircraft and they are more dispatch reliable than the EC225.
As is, the S-92 is exactly what the original name said it was a "HeliBus".
