Title
(EN) MIXER FOR COMBUSTOR AND METHOD OF MANUFACTURING
(FR) MÉLANGEUR POUR CHAMBRE DE COMBUSTION ET PROCÉDÉ POUR SA FABRICATION
Abstract
(EN)
A method 500 for fabricating a unitary mixer 100 is disclosed, said method comprising the steps of determining three-dimensional information of the unitary mixer 100 having at least one swirler 140, converting the three-dimensional information into a plurality of slices that each define a cross-sectional layer of the unitary mixer 100, and successively forming each layer of the unitary mixer 100 by fusing a metallic powder. Exemplary embodiments are disclosed, showing unitary mixer 100 comprising an annular housing 120 and a swirler 140, 160 having a unitary construction wherein unitary mixer 100 is made by using a rapid manufacturing process. In one aspect of the invention, the rapid manufacturing process is a laser sintering process. In another aspect of the invention, a mixer 300 having a unitary construction is disclosed comprising a swirler 380 having a plurality of radial vanes 382 arranged circumferentially around an axis 111 and oriented at least partially in a radial direction. In another exemplary embodiment, a unitary mixer 300 having circumferentially adjacent vanes 151, 152 forming at least one flow passage 154, 156 that is oriented at least partially in an axial direction with respect to the axis 111 is disclosed.

L'invention concerne un procédé 500 de façonnage d'un mélangeur monobloc 100, ledit procédé comportant les étapes consistant à déterminer des informations tridimensionnelles sur le mélangeur monobloc 100 comportant au moins un ensemble 140 de tourbillonnement, à convertir les informations tridimensionnelles en une pluralité de tranches dont chacune définit une couche en coupe transversale du mélangeur monobloc 100, et à former successivement chaque couche du mélangeur monobloc 100 par fusion d'une poudre métallique. On décrit à titre d'exemple des modes de réalisation présentant le mélangeur monobloc 100 doté d'une enveloppe annulaire 120 et d'un ensemble 140, 160 de tourbillonnement de construction monobloc, le mélangeur monobloc 100 étant réalisé par un processus de fabrication rapide. Dans un aspect de l'invention, le processus de fabrication rapide est un processus de frittage au laser. Un autre aspect de l'invention concerne un mélangeur 300 de construction monobloc comportant un ensemble 380 de tourbillonnement doté d'une pluralité d'ailettes radiales 382 disposées circonférentiellement autour d'un axe 111 et orientées au moins partiellement dans une direction radiale. Un autre mode de réalisation décrit à titre d'exemple concerne un mélangeur monobloc 300 doté d'ailettes 151, 152 circonférentiellement adjacentes formant au moins un passage 154, 156 d'écoulement orienté au moins partiellement dans une direction axiale par rapport à l'axe 111.
