1. A system for cooling a fin of a flying object, the fin having a given shape and the object being motivated by a propulsion means, the fin consisting of a first portion under the influence of hot exhaust gases from the propulsion means and a second portion in contact with cool ambient air, said cooling system comprising:

  • A wick located within the fin, said wick being suitable for guiding therethrough the flow of a pre-selected fluid while allowing vapors to escape therefrom upon vaporization of said fluid in the first portion of the fin, said wick being adjacent to and concentric with the interior surface of the fin and an internal wall, said wall mimicking the shape of the fin and being positioned so as to create a vapor channel between said wall and said wick, said channel receiving the vapors escaping from said wick and allowing the vapors to travel to the second portion where the vapors liquidate as heat dissipates into the ambient air, thereby cooling the entire fin.
