Thanks for the super detailed response Nick.

So if I understand correctly, you are saying that something else would break before 3Gs is achieved? You also talked about rotor stall. Is it possible to stall the rotor if you remain inside the RPM limits in a helicopter like the R22? Or is it that you would run out of power(within MAP limits) to maintain RPM with before reaching a high G load?

But if the FARs say that the helicopter has to be able to withstand a certain number of Gs, why would that not count for the entire helicopter? That means that the helicopter would not be able to handle the Gs required by FARs - right?(cause the rotor system would break or jack stall etc.)

The R22 doesn't use hydraulics, so is there some sort of equivalent problem since jack stall is impossible?

Is it that the rotor can't physically produce the load factor to bother static system because of rotor stall?


Im pretty confused about this


What about helicopter that can do a loop like the apache ah64


how many Gs would that be
