Title: Rocket nozzle construction and surfaces impervious to hot, high velocity gases

Abstract: A thrust nozzle for a rocket has an improved exit cone made of a strong, refractory material with tufts of high temperature fibers anchored in it to form a pile, in the manner of a carpet. The pile is on the inside of the nozzle, so that propulsive gases of the rocket may impinge directly thereon. The exit cone may be either rigid, as is conventional, or foldable so that the rocket may be stored in a minimal space. The folded exit cone may be extended by any of various actuating systems when the rocket is launched. This pile construction may also be used for other surfaces that must be exposed to hot, high velocity gases.
