RAM AIR KITES

CONSTRUCTION

We normally use reflex profiles, which means that the leading edge 

rises slightly, for the simple reason, that these profiles are self-

stable and will not look for negative angles.

The brakes act on the trailing edge and if they are pulled, the reflex 

will disappear and the kite will look further ahead with the risk of 

a frontal collapse. This picture shows when the brakes  are pulled.

With the speed system and the length of the brakes (except the mono lines), we can change the angle of the flaps, which gives us a more 

or less hollow profile for the down Wind. The difference is noticeable in forces acting on the profile with 10° of incidence.
