Virtual prototyping is a computer-based simulation used to conceptualize and test aviation products prior to physical production, enabling studies of interactions and potential interferences between components. It offers significant advantages including reduced manufacturing times, precise fitting of parts, and enhanced collaboration through real-time updates. Boeing's 777 exemplifies its success, being the first jetliner entirely designed through virtual prototyping, which led to substantial improvements in design efficiency and manufacturing processes.
Virtual Prototyping: Visualizing the Next Generation of Aviation Products
- 1. Virtual Prototyping: Visualizing the Next Generation of Aviation Products
- 2. What is Virtual Prototyping? • Per the Department of Defense – a virtual prototype is: “A computer-based simulation of a system or subsystem with a degree of functional realism comparable to a physical prototype.” • A virtual prototype is built from CAD (computer-aided design) drawings of separate assemblies that are gradually placed into the whole.
- 3. What is Virtual Prototyping? • Can be used for motion studies and studying interactions between machines and humans • Can be used to see if parts interfere with other parts as they move through their complete range of motion • Virtual prototyping allows design and analysis functions to be completely entwined
- 4. Why Virtual Prototyping? • Effects of structural change can be evaluated concurrently • Data on in-house manufactured parts and subcontracted parts can be imported into the program allowing the designer to determine if design changes will cause interference for other components
- 5. Why Virtual Prototyping? • Multiphysics software can also be imported into the prototype for assessing phenomena such as static and dynamic structural forces • Effects of electromagnetic radiation from radar, either onboard or from external sources can be solved
- 6. Advantages of Virtual Prototyping • Can run model through unlimited iterations to find the optimum design • Engineers can then design parts to fit more precisely, reducing manufacturing time and eliminating the need for large amounts of rework • Software has built-in collaboration tools that automatically update and distribute modifications to the model as soon as they are implemented
- 7. Advantages of Virtual Prototyping • Instrumental tool in shortening time to market • Allows design, manufacturing, and marketing to work in parallel rather than in series • As parts are designed, they become part of a database that can be used for inventory management
- 8. Boeing’s 777 was a Milestone! • First jetliner completely designed by computer without building a physical prototype • 1989, project started • 1992, design completed • 1994, first 777 took flight
- 9. Boeing’s 777 was a Milestone! • Largest and most complex virtual prototyping project ever attempted • Revolutionized Boeing’s approach to design, manufacturing, and test • Resulted in a 90% reduction in change requests, 90% reduction in material rework, and a 50% improvement in assembly tolerances for the fuselage
- 10. Where are we today? • The use of HP Workstations, powered by Intel® Core™ processors can run multiple applications in parallel – – 3D product development – Simulation and analysis – Digital manufacturing – Lifecycle management software
