Abstract

An aircraft water tank constituting an aircraft water tank is provided with a cylindrical section, dome sections, and mouthpieces. The mouthpieces are provided with mouthpiece bodies and annular wall sections that extend outward in the radial direction around the entire outer circumferences of the mouthpiece bodies between an inner liner and a fiber-reinforced resin layer, and are attached to the inner liner and the fiber-reinforced resin layer around the circumferences of openings. Outer surfaces of the annular wall sections contacting the fiber-reinforced resin layer are formed by uniform tension curved surfaces.

First claim

1 . An aircraft water tank comprising:
a cylindrical section; dome sections provided on both sides of the cylindrical section; and a mouthpiece provided in a center of each of the dome sections; the dome sections being provided with an inner liner and a fiber-reinforced resin layer provided on an outer peripheral surface of the inner liner; the inner liner and the fiber-reinforced resin layer being provided with coaxially positioned openings; each of the mouthpieces being provided with a cylindrical mouthpiece body that passes through the openings, and an annular wall section that extends outward in a radial direction from around the entire outer circumference of the mouthpiece body between the inner liner and the fiber-reinforced resin layer, and is attached to the inner liner and the fiber-reinforced resin layer around the circumferences of the openings; and the annular wall sections having a surface shape on a side contacting the fiber-reinforced resin layer that is formed by a uniform tension curved surface.

2 . The aircraft water tank according to claim 1 , wherein
the inner liner is thicker in portions thereof surrounding the openings than in other portions thereof.
