Two and Three Dimensional Systems for Computer Aided Geometric Design of Aircraft Surface and Components

摘要

Three interactive software systems dealing with the computerized definition, storage and handling of aircraft geometric shapes and entities in a multi-disciplinary design environment are presented. The systems are operated in an interactive fashion via use of low-cost graphic display terminals driven by a remote computer in a time-sharing mode. GEODEF is a system for interactive definition of complex aircraft surfaces, GEOBASE is a system for interrogation and manipulation of a computerized aircraft geometry data base, and DOG is a 3-D detailed structural and mechanical part definition system.
