| 20100126798 | PROCESS FOR THE PRODUCTION OF AN ACOUSTICALLY RESISTIVE STRUCTURE, THE ACOUSTICALLY RESISTIVE STRUCTURE THUS OBTAINED, AND COATING USING SUCH A STRUCTURE - A process for the production of an acoustically resistive structure that can be inserted in an alveolar structure so as to obtain a coating for the acoustic treatment, whereby the acoustically resistive structure includes at least one porous layer ( | 05-27-2010 |
| 20100181420 | COATING FOR ACOUSTIC TREATMENT THAT INTEGRATES THE FUNCTION OF HOT-AIR TREATMENT OF FROST - The invention relates to a coating for acoustic treatment at the surface of an aircraft, in particular at the leading edge such as the air intake of an aircraft nacelle, said coating including an acoustically resistive layer ( | 07-22-2010 |
| 20100276548 | ACOUSTIC PROCESSING STRUCTURE PARTICULARLY ADAPTED TO THE AIR INLET OF AN AIRCRAFT NACELLE - An acoustic treatment structure related to a leading edge onto which an aerodynamic stream flows, in particular at an air intake of an aircraft nacelle, includes—from the outside to the inside—at least one acoustically resistive substructure ( | 11-04-2010 |
| 20110114787 | ACOUSTIC TREATMENT PANEL WITH INTEGRAL CONNECTING REINFORCEMENT - An acoustic treatment panel includes, from the inside to the outside, a reflective layer ( | 05-19-2011 |
| 20110139940 | WAVE ATTENUATION PANEL INSERTED BETWEEN THE MOTOR AND AIR INLET OF AN AIRCRAFT NACELLE - An aircraft nacelle includes an air intake for channeling air flow in the direction of a power plant. The air intake includes an inside pipe that forms an aerodynamic surface in contact with the air flow and is extended toward the rear by an aerodynamic surface of a pipe of the power plant. The nacelle includes a wave attenuation panel which limits or prevents the propagation of at least one wave produced during the pumping of the power plant and includes a layer that is in contact with the air flow that can allow passage of the at least one wave, at least one alveolar structure, and a reflective or impermeable layer, wherein the wave attenuation panel is inserted between the air intake and the power plant, and the layer that is in contact with the air flow ensures the continuity of the aerodynamic surfaces that are arranged downstream and upstream and the wave attenuation panel includes inserts that can be inserted between the air intake and the power plant so as not to crush the wave attenuation panel. | 06-16-2011 |
| 20110168839 | DEVICE FOR CONNECTING AN AIR INLET WITH AN AIRCRAFT NACELLE ACTUATOR ASSEMBLY - An aircraft nacelle includes an air intake that makes it possible to channel the air in a pipe in the direction of a pipe of a power plant that is arranged in the extension of the pipe, whereby the pipe of the air intake includes at least one panel that integrates an acoustic treatment with an acoustically resistive porous layer that is in contact with the aerodynamic stream that enters into the nacelle, at least one alveolar structure, and a reflective or impermeable layer that forms the rear surface of the panel, a flange that ensures the connection between the air intake and the power plant including at least one wing that is connected to the air intake by a number of connecting elements, characterized in that some of the connecting elements have axes that are secant with the edge of the panel that delimits the pipe of the air intake. | 07-14-2011 |
