Method of producing structure

A method of producing a structure including a first component and a second component,

• the first component having a first surface, the first component including subcomponents,
• the second component having a second surface and a third surface, a predetermined contour degree being required for the second surface,
• the structure being assembled by coupling the third surface of the second component to the first surface of the first component after assembling the first component by coupling the subcomponents to each other, the structure being an aircraft, an aircraft component, a spacecraft or a spacecraft component,
• the method comprising:
• measuring profiles of the second and third surfaces of the second component which has not been coupled to the first component;
• measuring a profile of at least one fourth surface of the subcomponents which has not been coupled to each other, the first surface being to be formed by the at least one fourth surface;
• measuring a profile of at least one fifth surface of the subcomponents which has not been coupled to each other, the at least one fifth surface being determined as a surface which influences a profile of the first surface of the first component after coupling the subcomponents;
• assembling the first component by coupling the subcomponents with adjustment including at least one of load application and position adjustment;
• recording data representing the adjustment;
• estimating a changed profile of the second surface of the second component in a case of coupling the third surface of the second component to the first surface of the assembled first component, the changed profile of the second surface being estimated based on the measured profiles of the second to fifth surfaces and the recorded data representing the, the changed profile of the second surface being estimated before coupling the second component to the assembled first component;
• determining a coupling position of the third surface of the second component to the first surface of the first component based on the estimated changed profile of the second surface;
• and
• coupling the third surface of the second component to the first surface of the first component at the determined coupling position, the method further comprising;
• measuring an actual changed profile of the second surface after the third surface of the second component has actually been coupled to the first surface of the first component;
• and
• changing a condition used for estimating the changed profile of the second surface so that an index value representing a difference between the estimated changed profile of the second surface and the measured actual changed profile of the second surface decreases,
• wherein another structure is assembled by coupling a third surface of a second component of the another structure to a first surface of a first component of the another structure after assembling the first component of the another structure by coupling subcomponents of the first component of the another structure to each other, and
• a changed profile of a second surface of the second component of the another structure in a case of coupling the third surface of the second component of the another structure to the first surface of the assembled first component of the another structure is estimated under the changed condition, before coupling the second component of the another structure to the assembled first component of the another structure, the method still further comprising;
• measuring an actual changed profile of the second surface after the third surface of the second component has actually been coupled to the first surface of the first component;
• and
• changing a condition used for estimating the changed profile of the second surface so that an index value representing a difference between the estimated changed profile of the second surface and the measured actual changed profile of the second surface decreases,
• wherein another structure is assembled by coupling a third surface of a second component of the another structure to a first surface of a first component of the another structure after assembling the first component of the another structure by coupling subcomponents of the first component of the another structure to each other, and
• a changed profile of a second surface of the second component of the another structure in a case of coupling the third surface of the second component of the another structure to the first surface of the assembled first component of the another structure is estimated under the changed condition, before coupling the second component of the another structure to the assembled first component of the another structure.
