Abstract:
1. A method of manufacturing a wing, comprising: positioning a wing panel on a fixture and holding said wing panel immobile on said fixture; accurately placing critical coordination features in said wing panel and in two wing spars using a numerically controlled machine tool running on part programs incorporating digital wing product definition data from an engineering data authority, said critical coordination features being placed in said wing panel at locations having predetermined relationships with corresponding coordination features in said wing spars when said spars are accurately located in predetermined positions, spaced chord-wise from each other on said wing panel, specified by said digital wing product definition against said wing skin with said critical features in said spars and said wing skin positioned in said predetermined relation to each other; probing reference surfaces on said wing panel after positioning said wing panel on said fixture with a coordinate measuring system to obtain accurate position data for said wing panel on said fixture; normalizing said wing part program to coincide with said accurate position of said wing panel on said fixture; positioning said wing spars relative to said wing panel with said coordination features on said wing panel in registry with said coordination features on said wing spars and said wing spars thereby accurately located in said predetermined positions relative to said wing panel, as specified by said digital wing product definition; fastening said wing spars in fixed relation relative to said wing panel in said predetermined position.
