I know most if not all the variants of the Sikorsky UH-60 Blackhawk Utility Helicopter have the tail rotor oriented at roughly 20 to 15 degrees from vertical, but why is it oriented like that? It's the only helicopter I've seen designed this way, and I'm curious why it is.
Is it supposed to pull up on that axis? Why?
Because of it, everytime I fly the helicopter, it's pitch is wonky, is that intentional, why?
@ColonelRelford perhaps
@Delta7770 I suppose
yo, long time since ive seen you
@ThatKindaWeeb I think there's some sort of combined pitch/yaw control that keeps it from shifting unexpectedly, but I'm not sure on that.
@HuskyDynamics01 does it pitch off center irl?
I actually learned this just the other day about the UH-60 (and derivatives). In order for it to fit inside a C-130 for transport (one of the original design specifications), the nose had to be shorter. Combined with the fuel tanks being entirely behind the main cabin, the center of gravity range was entirely aft of the main rotor, meaning that the tail rotor needed to be canted in order to trim this out and rebalance the aircraft.
