The shapes of things to come—an introduction to the capabilities of the British Aerospace Numerical Master Geometry system
Published online by Cambridge University Press: 04 July 2016
Extract
The purpose of this paper is to give a brief introduction to the scope, flexibility and power of the British Aerospace Numerical Master Geometry (NMG) System, which is a computer aid for the design and manufacture of complicated three-dimensional curved surfaces. NMG is currently used at all ex-BAC sites within the Aircraft Group of British Aerospace for the purpose of generating and storing master computer models of the external shapes of aircraft or components. These master models may then be interrogated using a simple command language to derive information about the external shape for such diverse uses as aerodynamic analysis, detail structural design, numerically controlled machining and inspection. The use of such models means that everyone has access to the same basic information, and consistency is assured.
