Abstract

La présente invention a pour objet un procédé et un appareil pour l'obtention de gaz respiratoire pour aéronefs. Elle est caractérisée en ce que tout le volume de gaz respiratoire nécessaire en marche normale ou en régime permanent est obtenu exclusivement par séparation par adsorption réglée d'azote à partir d'air comprimé, à l'aide d'adsorbeurs exécutant des cycles commutables comportant des phases d'adsorption et de désorption à contre-courant, les adsorbeurs étant commandés de manière que, pendant chaque phase d'adsorption, un pourcentage d'azote croissant en fonction du temps soit déchargé à l'extrémité de sortie de l'adsorbeur intéressé et en ce que les valeurs admissibles de la concentration en oxygène sont ajustées en fonction de la pression de cabine par réglage de la quantité de gaz passant dans les adsorbeurs et/ou par réglage du rapport de la pression d'adsorption à la pression de désorption. Elle se rapporte aux avions et cabines spatiales.
