Abstract

La présente invention concerne un appareil de combustion pour moteurs à turbine à gaz. Cet appareil de combustion est formé d'un canal 2 disposé dans un carter 1. La paroi du canal 2 est formée d'une succession d'ondulations annulaires comprenant chacune une première partie tronconique 4, divergeant vers l'aval, et une seconde partie tronconique 5, convergeant vers l'aval, raccordée à la précédente, dont la longueur projetée sur l'axe de la chambre est supérieure à celle de la première partie. La première partie 4 comporte un grand nombre de perforations 6, de faibles dimensions, régulièrement réparties destinées à l'introduction d'air de refroidissement. Le canal 2 peut être réalisé par roulage d'une tôle, les perforations étant effectuées par bombardement électronique, les ondulations étant imprimées enfin par un procédé du type à la molette L'invention s'applique notamment à la réalisation des canaux de rechauffe pour turboréacteurs.The present invention relates to a combustion apparatus for gas turbine engines. This combustion device is formed of a channel 2 disposed in a casing 1. The wall of the channel 2 is formed of a succession of annular undulations each comprising a first frustoconical part 4, diverging downstream, and a second part. frustoconical 5, converging downstream, connected to the previous one, the length projected onto the axis of the chamber is greater than that of the first part. The first part 4 comprises a large number of perforations 6, of small dimensions, regularly distributed for the introduction of cooling air. Channel 2 can be produced by rolling a sheet, the perforations being effected by electronic bombardment, the corrugations finally being printed by a method of the roller type. The invention applies in particular to the production of heating channels for turbojets. .
