Abstract: ROCKET NOZZLE LINER IS FORMED FROM SUBSTANTIALLY IDENTICAL LONGITUDINAL SEGMENTS WHICH HAVE BEEN CIRCUMFERENTIALLY FUSED TOGETHER INTO AN INTEGRAL UNIT. RECTANGULAR FLAKES ARE PREFERABLY CUT FROM CLOTH MATERIAL HAVING GOOD INSULATIVE AND ABLATIVE PROPERTIES TO PROVIDE FLAKES OF THE SAME WIDTH BUT OF DIFFERENT LENGTHS, THE LENGTH OF A FLAKE BEING A FUNCTION OF THE NOZZLE LINER THICKNESS AT THE LONGITUDINAL POINT WHERE SUCHH FLAKE IS TH BE USED. THE FLAKES ARE PREFERABLY CUT SO THAT THE DOMINANT WARP FILAMENTS OF EACH FLAKE ARE GENERALLY PARALLEL TO ITS LENGTH, AND EACH LINER SEGMENT IS MOLDED FROM SUITABLY ARRANGED FLAKES TO PROVIDE A SEGMENT HAVING PREDETERMINED WARP FILAMENTS ORIENTATIONS THEREIN.
