A hard landing indicator mountable to a landing gear of an aircraft is provided. The landing gear has components displaceable toward each other upon the aircraft experiencing a landing. The hard landing indicator includes a first portion securable to one of these components and a second portion that projects outwardly from the first portion and oriented toward another component of the landing gear to be positioned within a path of displacement of the second component toward the first component. The second portion is impacted by this component upon this component being displaced during a hard landing of the aircraft. The impact leaves a visual mark on the second portion of the hard landing indicator to indicate that a hard landing has occurred. A landing gear equipped with and a method of installing such indicator are also provided.

A landing gear arrangement may comprise a first composite layer, the first composite layer having a cylindrical geometry, a metallic ring comprising an inner surface and an outer surface, the metallic ring perimetrically surrounding at least a portion of the first composite layer, the inner surface being in contact with the first composite layer, a metallic connecting tab extending away from the outer surface, and a second composite layer at least partially perimetrically surrounding the metallic ring and at least partially perimetrically surrounding the first composite layer, the outer surface being in contact with the second composite layer.

A metallic/composite joint may comprise a composite member having a flared end or an angled end, a liner perimetrically surrounding the composite member, and a metallic member perimetrically surrounding the liner. A first side of the liner contacts the composite member and a second side of the liner contacts the metallic member. The liner perimetrically surrounds at least a portion of the flared end. A through-thickness compressive stiffness of the liner may be less than a similar stiffness of the composite member.

A landing gear assembly is also provided. The landing gear assembly may include a thin-skin support member defining a cavity and a cylindrical cavity. A cylinder may extend from the cylindrical cavity with an axle extending from the cylinder. A torsion link may be coupled to the axle and a torsion interface of the thin-skin support member.

An aircraft landing gear bay roof, the roof forming a pressurization barrier between a pressurized upper compartment and a landing gear bay for the housing of a landing gear, comprising a roof wall forming the pressurization barrier. The roof wall is held by longitudinal gantries to which it is linked, and which extend over the entire length of the roof wall. The roof wall comprises a lower face configured to be installed inside the landing gear bay and an upper face configured to be installed outside the landing gear bay. At least one of the gantries is installed against the lower face of the roof wall.
