A heat exchange and noise reduction panel the panel for an aircraft comprising: an external surface intended to be swept by an airflow and from which fins extend along a first and a second main predetermined direction; cavities forming Helmholtz resonators, linked to the first ends of channels for the passage of air, the second ends of which communicate with said airflow, such that said channels form necks, referred to as Helmholtz resonators, extending substantially along the first direction; and at least one oil flow chamber extending between said external surface and said at least one cavity, and intended to discharge the thermal energy carried by the oil, wherein said channels are formed, at least in part, inside said fins.

Panel for heat exchange and improved noise reduction for a turbomachine

A double flow turbojet includes a fan including a disk centered on an axis of the fan which is provided with fan blades on its periphery, the blades having a leading edge, and an air inlet sleeve extending upstream of the fan and configured to delimit a gas flow designed to enter into the fan the air inlet sleeve having a collecting surface, the turbojet having an aspect ratio included in the interval where L/D is the form factor of the air inlet sleeve.

Low fan noise turbojet

A nacelle structure () surrounding a fan, the structure comprising an air inlet () having an inside surface (A) defining an air feed channel; and at least one ring () arranged in the air inlet and selectively movable between a deployed position in which the ring is moved radially inwards from the inside surface to provide an obstacle to shock waves coming from the fan, and a retracted position in which the ring is moved radially outwards from the deployed position so as to become flush with the inside surface and thus reconstitute the air feed channel.
