Publication number: 20170030372Abstract: A fluid transfer device including a rotor having two centrifugal wheels, and a stator incorporating a set of continuous axi symmetric return channels conveying the fluid from the first wheel to the second wheel. Each of the return channels includes in succession a diffusing portion that guides the fluid in a centrifugal direction, a bend portion that redirects the fluid stream in a centripetal direction, a return portion that guides the fluid along a centripetal path, and then an outlet portion formed in a first non-tubular part that guides the fluid towards the second wheel. In these channels, the diffusing portion and the bend portion are distinct parts, and the diffusing portion is formed in a second non-tubular part secured to the first non-tubular part. A method of fabricating the device.Type: ApplicationFiled: April 8, 2015Publication date: February 2, 2017Applicant: AIRBUS SAFRAN LAUNCHERS SASInventors: Sebastien BOUFFLERT, Philippe BOURDIN, Fabien TESSIER, Vincent LANGLOIS
