Abstract
L'invention se rapporte à un élément de paroi refroidissable construite pour combiner la technique de refroidissement par jets d'air et la technique de refroidissement par transpiration Selon l'invention l'élément de paroi comporte une première plaque munie de plusieurs trous s'étendant à travers la plaque et une seconde plaque munie de plusieurs orifices s'étendant à travers la seconde plaque. Des chambres séparées sont formées entre les deux plaques qui sont séparées l'une de l'autre Le rapport des pressions (PS /PD ) aux côtés opposés de la paroi variant avec le rapport entrela surface totale des orifices pratiqués dans la seconde plaque et la surface totale des trous pratiqués dans la premiere plaque selon la courbe de la figure ci-jointe. Application par exemple aux ailettes d'une turbine.
