Abstract
Les étages de compresseur 22A, 24A, 22B et 24B des moteurs à réaction respectifs 22 et 24 sont reliés, par l'intermédiaire de clapets respectifs 31, 32, 33 et 34, aux entrées d'éjecteurs de mélange 35 et 36, dont les sorties sont reliées, par l'intermédiaire de clapets respectifs 37 et 38, à un conduit d'alimentation commun 39, lequel est relié, d'une part, à un premier d'un ensemble de manifolds 40i montés en série et placés dans l'aile gauche 23 et, d'autre part, à un premier d'un ensemble de manifolds 41i montés en série et places dans l'aile droite 25. Des chambres sous pression d'éjecteur 42 k sont reliées aux manifolds 40i , et des chambres sous pression d'éjecteur 43 k sont reliées aux manifolds 41i . Une partie de chacune des chambres sous pression 42 k et 43k se trouve dans les bords d'attaque des ailes 23 et 25, et les injecteurs 29 et 30 y sont incorporés. Avions à décollage et atterrissage courts.
