Abstract: A propulsion system fastened to one side of an aircraft and having a longitudinal axis and a mid-plane and having a nacelle with two inner cowls, two outer cowls, two lower structural elements and two upper structural elements, wherein each outer cowl is articulated on a pylon by hinges with axes parallel to the longitudinal axis. The two outer cowls are contiguous at a separation plane containing the longitudinal axis and making, with the mid-plane, an acute angle. The axes are asymmetrical with respect to the mid-plane.

Abstract: An alveolar structure of an acoustic damping panel which is configured for damping at least one sound wave at a sound frequency, wherein the alveolar structure comprises at least one partition provided with at least one cavity configured such that the partition vibrates at a vibrational frequency substantially equal to the sound frequency of the sound wave to be damped. Also a method for producing such an alveolar structure, an acoustic damping panel comprising at least one such alveolar structure, and an aircraft comprising at least one such acoustic damping panel.

Abstract: A heat shield including a main component and at least one secondary component for a part of an aircraft are disclosed including a main component adhesively bonded to the part and at least one secondary component secured removably to the main component. The main component and the secondary component are made from at least one material that simultaneously provides thermal protection and fire protection, therefore making it possible to obtain a heat shield that is particularly effective and includes at least one removable secondary component allowing access.

Abstract: An alveolar structure of an acoustic damping panel which is configured for damping at least one sound wave of a sound frequency, wherein the alveolar structure comprises at least one attached element, separate from partitions, and configured for vibrating at a frequency substantially equal to the sound frequency of the sound wave to be damped. Also a method for producing such an alveolar structure, an acoustic damping panel comprising at least one such alveolar structure, and an aircraft comprising at least one such acoustic damping panel.
