Aircraft including an internal partition

An aircraft, including a structural portion such as a fuselage, a wing, or a tail, which portion comprises:

• a wall separating the inside from the outside of the portion and comprising fractions defining between them an inside volume of the portion;
• and
• at least one structural partition separating zones of the volume from each other, the partition comprising at least one flexible diaphragm suitable for deforming and at least two preferably rigid supports supporting the diaphragm in discontinuous manner, the partition being fastened to the structural portion by means that are separable.

A method, wherein, in an aircraft comprising a wall of a structural portion such as a fuselage, a wing or a tail, separating the outside and the inside of the portion and such that fractions of the wall define between them an inside volume of the structural portion, at least one structural partition is installed separating zones of the volume from each other, the partition comprising at least one flexible diaphragm suitable for deforming and at least two supports supporting the diaphragm in discontinuous manner, the installation being performed by fastening the partition to the structural portion by means that are separable.
