Abstract
This article will demonstrate how one physical instrument position measures the world’s largest one-piece, compound-contour, composite aircraft nose section using Coherent Laser Radar (CLR) technology by acquiring 1,294 engineering-defined surface points and features in less than two hours, a 70 percent improvement from the initial measurements. The product being measured has a length of greater than 15 m and circumference of greater than 18 m, and is rotated at 60° increments while CLR is static. Subject matter expert (SME) software initially orientates to three alignment features in a five-in. grid, as assigned by the software measurement plan. The alignment process continues to a secondary and individual primary alignment. When SME is instructed, the structure is rotated to six positions. The flow-time reduction and comparison to other applicable measurement equipment for this application will be explained.
