20110079378 | METHOD FOR MANUFACTURING A HEAT EXCHANGER AND EXCHANGER OBTAINED BY THE METHOD - The present invention relates to a method for manufacturing an air/fluid heat exchanger ( | 04-07-2011 |
20110146229 | Integration of a Surface Heat Exchanger to the Wall of an Aerodynamic Flowpath by a Structure of Reinforcement Rods - Setting in place of one or several coolers in the wall of a secondary flow of a bypass turbomachine. The wall extends from an intermediate casing toward a leading edge of a separator nose between a primary flow and the secondary flow. The wall includes a series of support arms attached to an intermediate casing, distributed over the perimeter of the wall and directed upstream. A series of surface air-oil heat exchangers forming wall segments are arranged end-to-end on the support arms, so as to form an annular wall. A shroud having a leading edge is arranged and fixed in the area of the upstream edges of the heat exchangers, so as to complete the wall. The support arms include hydraulic connectors connected to one another on each arm, adapted to cooperate with corresponding connectors in the area of the heat exchangers and in the area of the intermediate casing. | 06-23-2011 |
20110150634 | Integration of an Air-Liquid Heat Exchanger on an Engine - A bypass axial turbomachine includes a fan, a low pressure stator stage, a high pressure stator stage, the compressors being traversed by a flow referred to as primary flow of the turbomachine, at least one passage of discharge flow rate controlled from the primary flow in one of the stator stages toward the secondary flow, a heat exchanger of the surface air-oil (ACOC) type arranged flat on or in the wall surrounding the stator stages and defining the internal surface of the secondary flow, directly downstream of the junction of the passage of the discharge flow rate with said wall, so as to be run through by the secondary flow enriched with the discharge flow rate. | 06-23-2011 |
20120168115 | INTEGRATION OF A SURFACE HEAT-EXCHANGER WITH REGULATED AIR FLOW IN AN AIRPLANE ENGINE - The present invention relates to a surface air-cooled oil cooler ( | 07-05-2012 |
20120251373 | Gas Flow Separator with a Thermal Bridge De-Icer - The invention relates to a gas flow separator dividing the flow into a primary and a secondary stream, especially for a dual rotor axial turbomachine. The separator comprises a splitter nose of the turbomachine and includes a generally wedge-shaped leading edge in the gas flow to be split. The flow separator also comprises a metal blade having a longitudinal section in the form of an āSā and located in the nose in contact with the back of the leading edge and extending from the leading edge to a rear end of the separator at some distance from the leading edge, so as to be in contact with a heat source, such as a heat exchanger, located at some distance from the leading edge. | 10-04-2012 |
