Huey Tail Rotor
As any D model Huey pilot will tell you, she's not too good hot & high. This is because the tail rotor is on the wrong side (left - and trying to pull air through the vertical fin). It also spins down at the front, away from the rotorwash, losing even more effectiveness.
My question is why? Was this a design flaw? Vietnam photos circa 1972 show formations of Hueys, with a mix of left & right tail rotors and as, with the more modern 212, they spin up at the front.
The Bell 47 spins the same as the early Hueys but it of course has no vertical fin to impede the airflow.... as such, I wonder if they just copied the design, without much thought?
Similarly the Lynx tail rotor spins down at the front whilst the earlier Sea King spins up....... pourquoi?
Any venerable Huey design gurus out there?
