AIRFRAME PRODUCTION

摘要

Disclosed is a method of producing part of an airframe for attachment to a system. The method comprises: providing an initial structure; providing a reference structure; positioning the initial structure with respect to the reference structure such that its position/orientation relative to the reference structure is the same as the position/orientation relative to the system that it would have if the part of the airframe was attached to the system; specifying an inner mould line; applying, to an outer surface of the initial structure, material; and machining the material such that the position/orientation of the outer surface of the material with respect to the reference structure is the same as the position/orientation with respect to the system that the inner mould line would have if the part of the airframe was attached to the system.

1: A method of producing a first part of an aircraft airframe, the first part of the airframe being for attachment to a second part of an aircraft airframe, the method comprising:
providing an initial structure, the initial structure being part of the at least part of the aircraft airframe to be produced; providing a reference structure representative of the second part of the airframe; positioning the initial structure with respect to the reference structure such that the position and orientation of the initial structure relative to the reference structure is the same as the position and orientation relative to the second part of the airframe that the initial structure would have if the at least part of the aircraft airframe was attached to the second part of the airframe; specifying a surface, the surface being a desired inner mould line for the at least part of the aircraft airframe; applying, to an outer surface of the initial structure, one or more layers of material; and after the one or more layers of material have been applied to the initial structure, machining, using a cutting device, the layers of material such that the position and orientation of the outer surface of the layers of material with respect to the reference structure is the same as the position and orientation with respect to the second part of the airframe that the specified surface would have if the at least part of the aircraft airframe was attached to the second part of the airframe.
