Elbow strut (vortex stabilizer)

Abstract

This device is an inflatable elbow strut for a kite that becomes substantially rigid when inflated, and pliable when deflated. This elbow strut is integrally formed with an inflatable leading edge of the kite and extends rearwardly towards the trailing edge of the kite. This inflatable elbow strut increases kite steering responsiveness which providing a safer design than a fixed rigid structure.

1 . A kite device, comprising: 
 a kite structure having an inflatable leading edge and a trailing edge, said leading edge having right and left ends defining right and left wingtips;    inflatable elbow struts extending rearwardly from each of said ends at a strut angle to said trailing edge;    wherein each of said inflatable elbow struts is integrally formed with said inflatable leading edge;    wherein said strut angle is less than or equal to ninety degrees;    whereby said elbow strut is substantially rigid when inflated, and becomes pliable when deflated.
