Abstract: A design system for designing a tube for a gas turbine engine is described. The system including, in one embodiment, a computer workstation having a plurality of executable modules stored therein. The modules include a tube design module for routing a tube between tube fittings, a tube editing module for editing tube assembly geometry, and a tube detailing module for preparing detail drawings.

Abstract: A design system for designing brackets for gas turbine engines is described. The system may be implemented with a computer workstation and includes a part model library and a drawing note library. The computer workstation is configured to receive a bracket model in electronic form as input and has a number of executable modules stored therein. The system outputs a bracket master model and detail drawings. In one embodiment, the modules include a bracket intelligence builder module for generating intelligence data for the bracket model, a bracket unfolding module for unfolding a bracket model to a flat pattern, a bracket folding module to fold a bracket flat pattern, and a bracket minimum material check module to check for minimum distances between bracket pattern features. Other modules also are described and may form a elements of the system.
