Embodiment Construction

[0021] Wing-to-body joining methods and systems according to the present disclosure allow for faster and more certain wing-to-body assembly of aircraft and assembly of other large structures. The method involves measuring the 3D (three-dimensional) locations of optical targets at the interface to be joined (eg, the aircraft's wing root and wing stub) and using these locations to track the position of the wing and body. The location of the optical target on the constructed interface can be determined by scanning the interface to generate a surface profile of the interface to identify the location of the optical target. The wings can move to the body in at least two stages with a series of waypoints. In the first stage, the wings and body are moved far enough apart to avoid contact between the parts as much as possible. The position of the airfoil at each waypoint is determined by measuring objects on the airfoil. The error between the actual position and the desired position ...

Abstract

The present application discloses methods and systems for wing-to-body engagement. The disclosed wing-to-body engagement method includes commanding the wing to a first commanded position followed by iteratively repeating the first stage of movement and / or commanding the wing to a second commanded position followed by iteratively repeating the second stage of movement. The first-stage movement includes determining an actual position of the airfoil, calculating a first-stage difference between the actual position and the first commanded position, and commanding the airfoil to decrease by the magnitude of the first-stage difference. The second stage movement includes determining the actual position of the wings, determining the actual position of the body, calculating a second stage difference based on the second commanded and actual positions of the wings and body, and commanding the wings to reduce the magnitude of the second stage difference . Some implementations include performing a port side movement for a left wing of the aircraft and performing a starboard side movement for a right wing of the aircraft.

Description

technical field [0001] The present disclosure relates to automated assembly systems and methods. Background technique [0002] Aircraft assembly involves fitting together many complex and often large components in precise relationship. For example, wings and horizontal stabilizers (eg, vertical stabilizers, horizontal stabilizers) may be assembled substantially integrally and then attached to corresponding portions of the aircraft body. As another example, the fuselage of an aircraft may be a combination of several body assemblies, where each body assembly is a cylindrical portion of the fuselage. Some components, including some very large components such as wings, fuselage sections, and empennage assemblies, are designed with high precision, for example, with tolerances of less than 0.05 inches (in.) (approximately 1 millimeter (mm)) of relative position between parts degree assembly. [0003] In order to achieve the desired relative mounting with suitable accuracy, the ...
