Abstract

Claims (24)

1. A method of producing a structure by coupling a first component to a second component and inserting a shim into a gap formed between the first component and the second component, the structure consisting of an aircraft, an aircraft component, a spacecraft or a spacecraft component,

the method comprising:

measuring a first profile of a first surface of the first component before completing positioning of the first component and the second component to coupling positions of the first component and the second component, the first surface being to be mated with the second component;

measuring a second profile of a second surface of the second component before completing the positioning, the second surface being to be mated with the first component;

measuring a third profile of a third surface of the first component before completing the positioning, the third surface being measurable after completing the positioning;

measuring a fourth profile of a fourth surface of the second component before completing the positioning, the fourth surface being measurable after completing the positioning;

performing the positioning by butting the first and second components such that the first surface physically abuts against the second surface;

measuring a fifth profile of the third surface after completing the positioning;

measuring a sixth profile of the fourth surface after completing the positioning;

calculating a size of the gap based on the measured first to sixth profiles;

producing the shim based on the calculated size of the gap; and

coupling the second component to the first component in a state where the shim has been inserted into the gap and the positioning has been completed,

wherein a seventh profile of the first surface after completing the positioning and an eighth profile of the second surface after completing the positioning are calculated based on the measured first to sixth profiles, and

the size of the gap is calculated based on the calculated seventh and eighth profiles, and

wherein amounts of deformation of the first component and the second component after completing the positioning are calculated based on the measured third to sixth profiles, and

the seventh profile of the first surface after completing the positioning and the eighth profile of the second surface after completing the positioning are calculated based on the calculated amounts of the deformation, and the first and second profiles measured before completing the positioning.

2. The method of producing the structure according to claim 1 ,

wherein the shim is produced based on the calculated size of the gap without measuring any distance between the first surface after completing the positioning and the second surface after completing the positioning with a clearance gauge.

3. The method of producing the structure according to claim 1 ,

wherein the first component includes a first panel, or a first part having a first web, and

the second component includes a reinforcement, a fitting, a second panel, or a second part having a second web.

4. The method of producing the structure according to claim 2 ,

wherein the first component includes a first panel, or a first part having a first web, and

the second component includes a reinforcement, a fitting, a second panel, or a second part having a second web.
