HEXAGON: NEW CONSORTIUM TO DRIVE DEVELOPMENT OF ADVANCED MODELLING AND SIMULATION TECHNOLOGIES

The RDC will define, drive, and standardise rotordynamics modelling and simulation requirements, with the goal of enabling airframers and aerospace engine manufacturers to safely overcome the engineering challenges of new more sustainable and efficient propulsion systems.

The consortium will build on finite element methods that are deeply embedded throughout design, validation and safety certification workflows to apply next-generation multiphysics simulations. The RDC will meet to discuss and formulate strategies on how best to apply MSC Nastran, which is considered the most accurate digital alternative to expensive physical testing, to overcome the unique challenges of engine rotordynamics and their downstream effects on airframe safety under different flight conditions.

As rotordynamics continues to evolve, achieving improved fuel efficiencies using the open rotor concept presents aerospace engine manufacturers with numerous challenges including vibration control, bearing design, and system stability. The phenomenon of windmilling, particularly post fan bladeout (FBO), poses significant challenges for engine design and related aircraft safety certification.

Commenting on the launch of the RDC, Subham Sett, Head of Multiphysics simulation at Hexagon said: “The industry needs simulation technologies that enable rapid innovation and confidence that engineering decisions are correct. The launch of the RDC marks a significant step by leading aerospace manufacturers to pioneer new simulation methodologies that shorten development cycles and facilitate the delivery of more efficient propulsion systems.
