Vorrichtung zum thermischen Schutz der inneren Wand einer einem ablativen Gasstrom unterworfenen hohlen Struktur und Verfahren zu deren Herstellung.

摘要

The thermal protection device is obtained by the winding of refractory yarns (3) having small loops and of radial strengthening and reinforcing picots which are also made from refractory fibres advantageously twisted together. The small loops and the picots have an orientation and/or a pitch which are predetermined in relation to the direction of the ablative gas flow in the hollow structure. Application to the production of the barrel of a ram jet engine chamber.
