The primary object of this invention is to build a Allison Sled type kite using the material of the main sail as longitudinally stiffening.
The material used for construction of this kite as mention in the patent can be any light material that is impervious to the passage of air. The patent suggests a variety of plastic film and tight weave fabrics but the inventor prefers paper to cut cost.
The paper material needs to be of a substantial stiffness.
The paper is folded and glued to form longeron  stiffening (see graphic drawing).
A port is suggested when flown in strong winds, paper streamers are added for stability.
