Publication number: 20200164989Abstract: A two-flow jet engine comprising a high-pressure compressor and a drawing system configured to draw air from said jet engine and send it to an air system, and which comprises a pressurized air supply which draws pressurized air from the high-pressure compressor, a pipe which draws outside air, a turbine of which an inlet is connected to the outlet of the pressurized air supply, and a compressor of which an inlet is connected to the pipe, and an outlet is connected to the air system, and where the rotation of the turbine drives the rotation of the compressor. This particular arrangement makes possible an energy gain by virtue of the combined action of the turbine and of the compressor.Type: ApplicationFiled: November 18, 2019Publication date: May 28, 2020Inventors: Pierre-Alain PINAULT, Stephane WARNET, Stéphane MACHADO

Patent number: 8800917Abstract: An aircraft engine pylon aft aerodynamic fairing includes upper spars, transverse stiffening ribs, lower spars and a trailing edge where the upper spars and lower spars join together. In this fairing, a profiled structure is formed according to a profile open to the outside of the fairing. In a first end portion, the profiled structure comes to be enclosed between an end portion of the lower spars and the ends of at least one transverse stiffening ribs flush with the lower spars. This structure extends between the lower spars and the upper spars over a straight central portion inclined relative to the first end portion, and comes in a second end portion flush against a portion of the upper spars, parallel to the first end.Type: GrantFiled: November 20, 2012Date of Patent: August 12, 2014Assignee: Airbus Operations SASInventors: Stephane Machado, Fabien Raison, Stephane Romani
