Airspeed and line tension on top of circle
« on: July 07, 2017, 05:48:22 AM »
With centrifugal force changing with the square of speed, overhead line tension primarily depends of the actual speed of the airplane when it flies along a wingover path through the top of the hemisphere.

One may assume that this speed is lower than in level flight, but does this take into account the reduction of induced drag resulting from the wing no longer generating lift in knife edge flight?

Assuming that the lift in horizontal flight is 18 Newton, and that the span is 1,5m, the induced drag is only about 0,23 Newton. This is a small force compared to the drag of the plane and the lines.

Wolfgang
