As someone noted there is pitch control at the center of each blade. Now if the pitch is constant, it would never fly as the lift from all 3 blades would always be directed toward the center – cancelling out lift.
So what would have to happen is that as a blade approaches the top, the pitch would have to be increased to positive pitch for lift. Then at left and right position, it would have to be at 0 degrees, or slight pitch used to control left or right direction. Then at the bottom it could be “negative” to generate lift during this phase.
In this whole process it looks like it would be generating a lot of drag in the process – in the transitions, and when in the left and right positions.
On our helicopters, the blades are always generating lift, and then the disk is maneuvered for directional control. This is obviously significantly more efficient.
I got a helicopter for my girlfriend,
Hope she doesn't outfly me soon! |
then enter it into heli competition! since it is a heli! speaking of that has anyone ever entered a chinook style heli for F3C? lol or a coaxial?
