Systems and methods are provided for insulation and moisture drainage. One exemplary embodiment is an apparatus comprising a bay blanket configured to insulate an aircraft. The bay blanket includes insulation, and a first waterproof lip that protrudes from the insulation in an outboard direction towards a frame of the aircraft and extends along a length of a leftward side of the bay blanket. The bay blanket also includes a second waterproof lip that protrudes from the insulation in an outboard direction towards the frame of the aircraft along a length of a rightward side of the bay blanket.

In order to facilitate the thermoacoustic insulation of an aircraft portion, a method for manufacturing a thermoacoustic insulation module for an aircraft comprises a step of providing a mat configured to provide thermoacoustic insulation of an aircraft portion, followed by a step of attaching a bendable structure to the mat, followed by a step of bending the bendable structure, along a bending axis parallel to a longitudinal direction of the mat, such that the bendable structure forms a load-bearing structure supporting the mat in a curved shape.

In order to facilitate the thermoacoustic insulation of an aircraft portion, a thermoacoustic insulation module for an aircraft comprises a mat and a load-bearing structure detachably attached to the mat and supporting the mat in a curved shape, with an axis of curvature parallel to a longitudinal direction of the mat. A thermoacoustic insulation method for insulating an aircraft portion comprises a step of inserting the thermoacoustic insulation module into the aircraft portion, followed by a step of detaching the mat from the load-bearing structure, followed by a step of attaching the mat to an aircraft structure delimiting the aircraft portion, followed by a step of removing the load-bearing structure from the aircraft portion.

Methods and apparatus for forming and installing insulation blankets in a vehicle compartment are disclosed. An example apparatus includes an insulation blanket that includes an outer layer, an insulation layer disposed in the outer layer, and a first fastener disposed in the insulation layer. The outer layer and the insulation layer are to form to a first channel. The first fastener is to receive, via the first channel, a first portion of a vehicle compartment frame to sealingly couple the insulation layer and the outer layer of the insulation blanket to the vehicle compartment frame.

A self-perforating spacer has a first part and a second part, the first part including a through-seat, the first and second parts being designed to be assembled together and the self-perforating spacer including a cutting system that cuts when the self-perforating spacer is assembled. A method for assembling a self-perforating spacer on an insulation blanket and an insulation blanket fitted with at least one self-perforating spacer is also described.

Methods and apparatus for retaining a fastener receiver are disclosed. An example apparatus includes a retainer to retain a nut assembly adjacent an object. The retainer includes a first plate defining a first opening. The first plate is to couple to the object. The first opening is to receive a portion of the nut assembly when the retainer is coupled to the object. The retainer includes a second plate defining a second opening and including a first deflectable tab adjacent the second opening. The second plate is to couple to the first plate opposite the object. The deflectable tab of the second plate is to cover a portion of the first opening of the first plate. The first deflectable tab is to deflect to receive and retain the portion of the nut assembly in the first opening when the retainer is coupled to the object.

An assembly including a support panel of an internal fixed structure, a thermal protection element and a plurality of fastening systems. Each fastening system includes a female part secured to the support panel and which has, in its interior, a circular shoulder, and a male part including a sleeve pierced with a main bore, a slide movable in translation in the main bore and a plurality of balls. For each ball, the sleeve has a secondary bore, and each ball is movable along the secondary bore between a locking position and an unlocking position. The slide is movable in translation between a blocking position and an unlocking position. Such an assembly makes it possible to fasten the thermal protection element to the support panel in a simple and rapid manner, also permitting easy removal if necessary.

A thermal expansion joint is disclosed. In one non-limiting example the thermal expansion joint includes a bottom portion extending between a support structure and a trailing edge and the support structure is positioned proximate to a heat source. Furthermore, the thermal expansion joint includes a side portion. In some embodiments, the thermal expansion joint includes an overlapping portion coupled to the bottom portion and extending from a flange portion towards the side portion. Moreover, the overlapping portion overlays and is biased against the side portion to enable thermal expansion during heating by extending towards the flange portion and sliding along a top surface of the side portion.

A mounting assembly for mounting a sound-deadening body to a fuselage of an aircraft and a method for attaching a sound-deadening body to a fuselage of an aircraft using the mounting assembly is disclosed herein. In a non-limiting embodiment, the mounting assembly includes, but is not limited to, a retaining member that is configured to engage the sound-deadening body. The mounting assembly further includes an isolating member that is engaged with the retaining member. The isolating member is configured for connection to the fuselage and is further configured to diminish transmission of vibration from the fuselage to and through the retaining member, and therefore to reduce the transmission of sound into the cabin.

An insulation attachment system for an aircraft includes a first insulation blanket including a first tab at an aft end of the first insulation blanket and a second insulation blanket including a second tab at an aft end of the second insulation blanket. The system also includes a third insulation blanket and a first attachment component disposed on an outboard forward portion of the second insulation blanket and clasping a first frame member of the aircraft such that the first tab and the second insulation blanket are attached to the first frame member. The system also includes a second attachment component disposed on an outboard forward portion of the third insulation blanket and clasping a second frame member of the aircraft that is aft of the first frame member such that the second tab and the third insulation blanket are attached to the second frame member.
