Spacer and gasket assembly for use on an aircraft
First Claim
1. A spacer and gasket assembly for receipt between a static structure and a removable structure with fastener holes and the static structure and removable structure being engaged through a multiplicity of fasteners having a shaft diameter, the fasteners adapted to apply a compression on the gasket and spacer assembly, the static structure and the removable structure having opposed, facing walls, the spacer and gasket assembly comprising:
- multiple non-compressible spacers having a spacer thickness, the spacers for receipt between the static structure and the removable structure, the spacers having a flat top and a flat bottom; and
a gasket having a deformable, flowable, sticky, elastomeric body with a top and a bottom surface and a skeleton having a skeleton thickness less than a body thickness, the skeleton substantially encapsulated by the body, the gasket having an uncompressed gasket thickness; and
a spacer thickness, wherein the spacer thickness is about 40-80% of the uncompressed gasket thickness wherein the spacers do not encircle the fastener;
wherein spacers and the gasket are placed under compression between the facing walls of the static structure and the removable structure such that at least one of the top or bottom surface of the gasket body is in direct contact with one of the facing walls.

Abstract
A spacer and gasket assembly is shown for receipt between a static structure having a surface and fastener holes therethrough and a removable structure having a surface and fastener holes. The static structure and removable structure are engaged through a multiplicity of fasteners having a shaft diameter. The fasteners are adapted to apply a compression on the gasket between the static structure and the removable structure. The static structure and the removable structure have opposed, typically flat, facing surfaces. The spacer and gasket assembly comprising a substantially non-compressible spacer adapted for receipt between the static structure and the removable structure having a spacer thickness. A gasket has a sticky, deformable, flowable, elastomeric body and a skeleton having a skeleton thickness, the skeleton substantially integral with the body. The gasket has an uncompressed gasket thickness. The spacer and the gasket are adapted to be placed substantially between the facing walls of the static structure and the removable structure and the removable structure will compress and deform the gasket when the fasteners are torqued down.
