THERMAL PROTECTION DEVICE FOR THE INTERNAL WALL OF A HOLLOW STRUCTURE SUBJECTED TO ABLATIVE FLOW AND METHOD FOR MANUFACTURING THE SAME.

摘要

P The thermal protection device is obtained by winding refractory loop son (3) and radial arming pins and reinforcement also refractory fibers advantageously twisted. The loops and spikes have a predetermined orientation and / or pitch relative to the direction of the ablative flow in the hollow structure. BR/ Application to the realization of the ferrule of a ramjet engine chamber. / P
