About FirstFlight

The Wright Brothers - experiments - drift balance

The choosen aerofoil shape is first fixed to the top bar, and then the angle of attack is set by twisting the bottom frame. When the fan is turned on the indicator provides a direct reading of the lift/drag ratio.

Play the movie to see the movement of the arms.
