The benefits of an extended digital twin to support the design of complex system

The complexity of products increases with the number of actors involved in their design and use. Eco-design introduces an additional dimension to complexity by considering from the concept study phases the complete life cycle of the product to the recycling of components. In order to be able to design the best concepts that match customer needs and maximize product value for users and vendors, we need to dramatically increase the agility and efficiency of the physical systems design process. The digital twin is an option, if it introduces at least a new extended property to manage propagation of any designer proposal of modification toward the complete multi physics system of simulation to identify all potential multi systems and multi physics clashes.

In this presentation, we will share results based on CoSApp open source prototype that show how to access this new property.

Speaker bio: After a PhD in Numerical Analysis from ENSAM Engineers School, Guy De Spiegeleer joined SEP (Société Européenne de Propulsion) to design the cryogenic pump for Ariane 6 upper stage rocket. He developed a new rocket engine preliminary design tool in 2000 still in use at ArianeGroup. After being involved in Vulcain 2 Flight Recovery Program, he joined Safran Aircraft Engine to lead several R&T project (most of them at European level) dealing with new technologies and engine architectures to prepare LEAP engine development than the extensions of LEAP (Open Rotor, Ultra High ByPass Ratio and LEAP Evolutions projects). In between, he also leads the low pressure compressors department and put in place at Safran the project managers skill development program.

He is co-founder of the CoSApp initiative, a new Collaborative Design Platform for Complex System Simulation. He is involved in think-tanks dealing with digital transformation impact on complex system design processes.
