The method comprises positioning and fixing the first panel to the bearing structure, positioning and fixing the second panel to the bearing structure with the second panel overlapping a raw edge of the first panel, jointly cutting the first panel and the second panel in the overlap area to form a connection edge of the first panel and a connection edge of the second panel, withdrawing scrap cuttings from the first panel and scrap cuttings from the second panel, and friction stir welding the connection edges.
Abstract: A turbomachine comprising an engine body and an annular nacelle. The nacelle has an air intake comprising an outer skin, an inner skin, an air intake lip connecting the outer and inner skins together, and an annular frame connecting the outer and inner skins together. The turbomachine comprises a system for de-icing the air intake having an air bleeding port for bleeding a flow of hot air from the engine body, and two interconnected heating systems. An inner skin heating system receives the hot air flow to heat, by means of a gas-liquid heat exchanger, a heat transfer liquid contained in a hydraulic circuit arranged in part in the heat exchanger and in the inner skin. An air intake lip heating system diffuses the flow of hot air, once it has passed through the inner skin heating system, through the annular frame to heat the air intake lip.

The nacelle comprises reverser flaps where each one is articulated between a stowed position in which it is not in the bypass duct and a deployed position in which it is across the bypass duct. The turbofan has at least one reverser flap with at least one leakage window configured to allow airflow in the deployed position. The at least one reverser flap has at least one fin extending across the leakage window.
Abstract: An assembly method for an air intake of a jet engine of an aircraft, comprising providing an acoustic panel, an outside panel, flanges and a collar, arranging a rear edge of the acoustic panel on an assembly chassis. The flanges and the collar are attached at the rear edge of the acoustic panel. A rear edge of the outside panel is attached to the attached collar. A first set of geometric data of a front edge of the acoustic panel is measured and a second set of geometric data of a front edge of the outside panel is measured. A U-shaped lip as a single element is produced based on the two sets of geometric data. An inside leg of the lip is attached to the front edge of the acoustic panel and an outside leg of the lip is attached to the front edge of the outside panel.
