Axle Slot Angle - What Effect?
I have a question for you physics and taildragger experts.
I am working on the landing gear of my AA Nieuport 17 and got to thinking about the angle of the axle slot in the V of the landing gear.
The way the kit is currently designed, the slot angles a little forward at the top when the plane is in flying attitude. This angle resulted when AA modified the gear from the forward legs being vertical to swept back at the bottom. The slot is parallel with the front legs.
My setup, which is basically a copy of Rick Bennett's, produces an angle toward the rear at the top when in flying position. A review of the Hardesty and Rosendahl (sp) drawings shows a slight angle back at the top.
Fokkers, Sopwiths, etc. seem to be vertical.
It would appear to me that the different angles of the axle slots would cause a steering action on landing and takeoff when one side of the axle moves up more than the other.
Does anyone have any data, or comments on this?
