Model-Based Definition

Delivering Power to Protect - Faster, Smarter & Better

By adopting innovative digital engineering processes, we are transforming the way we design and manufacture our world-class technology and improving the through life performance of our products.

An example of this is Model-Based Definition which, when applied within a Model-Based Enterprise practice, is helping us to design and deliver cutting-edge power and propulsion technology to our customers more efficiently and much faster.

What is Model-Based Definition?

Model-Based Definition (MBD) is the practice of using 3D Computer-Aided Design models with integrated information to communicate all the detail needed to design and manufacture our products. MBD has enabled the replacement of traditional 2D-based drawings with 3D feature-rich, semantic data that can be easily shared, re-used and re-purposed by its many users, from design and engineering to manufacturing and quality control.

What is Model-Based Enterprise?

Model-Based Enterprise (MBE) is achieved by combining all the various types of digital models that drive process efficiency, improve collaboration and transparency, reduce costs, and accelerate delivery across an organisation. Model-Based Definition is one of the foundational elements for MBE, as is Model-Based Systems Engineering, Model-Based Manufacturing and Model-Based Inspection.

The Digital ‘O’ – Our Model Based Enterprise

At Rolls-Royce, we refer to our Model-Based Enterprise as our Digital ’O’. The Digital 'O' provides our engineers with a framework upon which they can design, develop and test a digital twin version of our products alongside its physical counterpart, to optimise efficiency and cost before the physical product is manufactured.

Model-Based Definition and Enterprise in Practice

Model-Based Definition (MBD) tools have been in use for the past decade at Rolls-Royce. MBD methods and processes have been implemented on some of our Technology Demonstrators with success and we are now applying them to programmes such as B-52, FLRAA, Tempest and the Global Combat Air Programme (GCAP). The application of Model-Based Definition across all areas, including design, manufacturing, inspection, is achieving game-changing results.

By integrating Model-Based Definition into our daily work practices as part of our Model-Based Enterprise (our Digital 'O'), we have extended the use of Model-Based Definition beyond our internal organisation to enhance collaboration with our partners, suppliers, and customers.
