One of the things missing from the discussion on the loss of fenestron effectiveness / yaw divergence / whatever, is the effect that high yaw rates have on the governor, which in turn will affect the lift on the main rotor.. .When yawing to the left in the Gazelle, the governor will sense this as a higher-than-normal N2 speed, and will attempt to reduce fuel flow to get the N2 speed back to normal. At high rates of yaw, this will significantly affect the main rotor speed, (i.e. reducing it). . .If you don't believe this, try a pedal turn to the left in the hover without touching the collective- you will descend - best to try this starting with the wind on the left hand side so you end up into wind.. .Turning to the right in the hover, and you will climb. Works in every helicopter I've ever flown that has a governor - the only difference is due to the direction of rotation of the main rotor.. .So, in a high yaw rate to the left, not only will you be disorientated by the rate of turn, but you will proabably be descending without knowing it as well.... .Best regards to all, and the Gazelle is one of my favorite (or is it favourite) machines. Wish I had one...
