Abstract

a method for mounting, in a nacelle for a hydrogen-powered aircraft, a box containing at least part of the equipment necessary for transporting dihydrogen to an engine of the aircraft, called H2 box, the mounting method comprising a step of positioning the H2 box in the nacelle by virtue of at least one rail secured to a chassis of the nacelle, or to the H2 box, or both.

Claims (18)

1 . A method for mounting, in a nacelle for a hydrogen-powered aircraft, a box containing at least part of an equipment necessary for transporting dihydrogen to an engine of the aircraft, called H2 box, the method comprising:

positioning the H2 box in the nacelle with at least one rail secured to a chassis of the nacelle, or to the H2 box, or to both,

wherein the at least one rail extends longitudinally parallel to a longitudinal axis of the nacelle between a first end, disposed in the nacelle, and a second end, disposed outside the nacelle.

2 . The method according to claim 1 , further comprising:

positioning the at least one rail with respect to the chassis in an installation position of the H2 box.

3 . The method according to claim 2 , wherein the positioning the at least one rail comprises immobilizing the at least one rail in the installation position of the H2 box.

4 . The method according to claim 2 , wherein the positioning the at least one rail comprises positioning a mounting interface between the chassis and the at least one rail.

5 . The method according to claim 4 , wherein, during the positioning the at least one rail with respect to the chassis, the at least one rail is screwed to the chassis via the mounting interface.

6 . The method according to claim 4 , wherein, during the positioning the at least one rail with respect to the chassis, the at least one rail is moved into the nacelle while being guided by at least one guide roller of the mounting interface.

7 . The method according to claim 4 , wherein the at least one rail is secured to a first structural element and a second structural element via the mounting interface.

8 . The method according to claim 7 , wherein the at least one rail is secured to the first structural element and the second structural element via at least four mounting interfaces.

9 . The method according to claim 1 , wherein the positioning the H2 box in the nacelle comprises guiding the H2 box along the at least one rail via at least one guide roller.

10 . The method according to claim 1 , further comprising:

securing the H2 box in the nacelle, and

then, removing the at least one rail from the nacelle.

11 . The method according to claim 1 , further comprising:

separating the at least one rail from the chassis; and

removing the at least one rail from the nacelle, such that the H2 box remains in the nacelle.
