Aircraft Portion with Modular Fluid Distribution and Associated Arrangement Method

An aircraft portion comprising:

• a fuselage delimiting a cabin extending according to a longitudinal axis, the cabin comprising a first cabin portion and a second cabin portion;
• a first partition wall configured to extend substantially perpendicular to the longitudinal axis and configured to separate the first cabin portion and the second cabin portion, the first partition wall being configured to be mounted on the fuselage at a first longitudinal coordinate or at a second longitudinal coordinate along the longitudinal axis, the second longitudinal coordinate being located to a rear of the first longitudinal coordinate relative to an orientation direction substantially parallel to the longitudinal axis;
• and
• at least one first fluid circuit configured to fluidly connect at least one first source of a first fluid and the second cabin portion, the at least one first fluid circuit comprising:
• at least one first pipe including:
• a first section comprising at least one first outlet configured to deliver the first fluid into the cabin between the first longitudinal coordinate and the second longitudinal coordinate;
• and
• a second section comprising at least one second outlet configured to deliver the first fluid into the cabin to the rear of the second longitudinal coordinate relative to the orientation direction, the first section of the at least one first pipe being configured to be fluidly connected to the at least one first source by the second section of the at least one first pipe;
• at least one first control device configurable between an open configuration, wherein, the first section of the at least one first pipe is in fluid communication with the second section of the at least one first pipe, and a closed configuration, wherein, fluid communication between the first section of the at least one first pipe and the second section of the at least one first pipe is interrupted;
• wherein the at least one first control device of the at least one first fluid circuit is configured to be in the open configuration when the first partition wall is mounted at the first longitudinal coordinate, and
• wherein the at least one first control device of the at least one first fluid circuit is configured to be in the closed configuration when the first partition wall is mounted at the second longitudinal coordinate.
