Abstract

La présente invention concerne une tuyère à
section variable. Une telle tuyère présente à l'extrémité
d'une paroi fixe (11) deux demi-coquilles pivotantes (13) articulées, selon un axe de rotation A, solidaires de la paroi fixe et dont les bords latéraux (18) sont reçus dans des glissières ménagées dans des poutres fixes (12) également solidaires de la paroi fixe. Un joint d'étanchéité (35) continu assure l'étanchéité entre la paroi fixe (11) et les demi-coquilles pivotantes (13).
De telles tuyères sont destinées à équiper les avions dits "d'affaires" et "commerciaux" de sorte que la poussée optimale de ces avions, au décollage, en montée et en vol de croisière, puisse être adaptée à volonté.
