Exam question
Hi I`m an engineer currently studying for my module 12 [helicopters]. I have come across a question which i don`t understand and the pilots in work suggested this site for an answer. question is when a helicopter has a main rotor which rotates anti-clockwise when viewed from above , what happens if a loss of anti torque drive happens in cruise speed in flight?
a. Nose pitches slightly up and a/c yaws left
b. Nose pitches slightly up and a/c yaws right
c. No appreciable change.
I know it will yaw right but i am assuming it pitches slightly because of the loss of drive [power] to the tail being transferred to be main rotor and thus a slight change in attitude. Is this correct or does any of you pilot types know more than the ones i asked at work?
