Abstract
A fastening system to couple a first aircraft structure and a second aircraft structure is disclosed. The fastening system includes a fastener, a nutplate having a body defining an opening to receive the fastener, a flange extending from the body to engage an outer surface of the first structure, and a first sleeve protruding from the flange in a direction away from the body, the first sleeve to couple to a first bore formed in the first structure and prevents rotation of the nutplate relative to the first structure.
Claims14
A fastening system to couple a first structure and a second structure, the fastening system including:
- a fastener having a threaded portion;
- a nutplate having:
- a body defining an opening to receive the fastener, the opening having internal threads to threadably receive the threaded portion of the fastener;
- a flange extending from the body to engage an outer surface of the first structure;
- a first sleeve protruding from the flange in a direction away from the body, the first sleeve to couple to a first bore formed in the first structure, the first sleeve, when positioned in the first bore, to prevent rotation of the nutplate relative to the first structure;
- and
- a second sleeve insertable in a second bore formed in the second structure, wherein a first end of the first sleeve and a second end of the second sleeve opposing the first end of the first sleeve define a gap to enable the first end of the first sleeve to be spaced apart from the second end of the second sleeve when the first sleeve is coupled to the first bore and the second sleeve is coupled to the second bore, the gap to enable insertion of the first sleeve in the first bore and the second sleeve in the second bore without contact between the first sleeve and the second sleeve.
