Today I tried to stabilize a SSSL by adding a second smaller kite (pocket sled) to an Y bridle on the top skin of the SSSL, attached around the placement of the second rib from center, sexond bridle attachment from leading edge.
The experiment was a failure. Still I’d like to explain my thinking.
The Pocket Sled (PS) flies stably at zenith but with low pull and low lift to drag.
If the SSSL zooms out to either edge, the y bridle will elongate either bridle point, hopefully steering the kite. In this way, the kite should both stay stable.
There is another bad thing that might happen. is the yaw is not pointing upwind, the PS could pull (without steering) the trailing edge of the SSSL such that is will dive into the ground, but this should only happen if the first steering effect fails completely.
Anyways, I might redo the test with the PS attached to a more rear bridle attachment (more steering effect?) and also once without the Y bridle and attachment near center leading edge.
But I am not overly optimistic about the idea at this point.
