Hexagon’s Manufacturing Intelligence division and Boeing have teamed up to establish the Rotor Dynamics Consortium (RDC) alongside several key players in the aircraft and aerospace engine sectors.
The RDC aims to set the standard for rotordynamics modeling and simulation, facilitating the development of sustainable and efficient propulsion systems for airframers and aerospace engine manufacturers. This initiative will enhance existing finite element methods, integrating next-generation multiphysics simulations into design, validation, and safety certification workflows.
Central to the RDC’s mission is the application of MSC Nastran, a highly accurate digital alternative to costly physical testing. This tool will be utilized to address the unique challenges posed by engine rotordynamics, including their effects on airframe safety under various flight conditions.
One of the consortium’s primary focuses is the improvement of fuel efficiency through the open rotor concept, which presents challenges such as vibration control, bearing design, and system stability. Additionally, addressing the phenomenon of windmilling, especially post fan blade-out (FBO), is crucial for advancing engine design and ensuring aircraft safety certification.
At the RDC’s inaugural meeting on June 28, members will present and discuss new simulation solutions aimed at achieving regulatory compliance and establishing industry standards. These discussions will incorporate the first enhancements to the rotordynamics solution sequence SOL 128 Nonlinear Harmonics, released in MSC Nastran May 2024, to improve windmilling analysis robustness and performance.
Subham Sett, head of multiphysics simulation at Hexagon, commented on the consortium’s launch: “The industry requires simulation technologies that enable rapid innovation and ensure confidence in engineering decisions. The RDC represents a significant step by leading aerospace manufacturers to pioneer new simulation methodologies that expedite development cycles and support the creation of more efficient propulsion systems.”
He further emphasized MSC Nastran’s crucial role in structural validation, noting Hexagon’s commitment to investing in innovative technologies to support the consortium’s objectives. While initially driven by aero engine needs, these technological advancements are expected to benefit automotive and energy turbomachinery applications as well.
The RDC’s first meeting will coincide with the ASME Turbo Expo 2024 in London, featuring presentations on Rotordynamics Methods and Modelling and Non-linear Rotordynamics. Following these presentations, the RDC Consortium Kickoff meeting will convene, bringing together experts and stakeholders in rotordynamics modeling and simulation to foster collaboration and advance R&D efforts.
Confirmed participants include industry giants such as The Boeing Company, General Electric, Safran Aircraft Engines, Pratt & Whitney, Rolls Royce, Honeywell, MTU Aero, and ITP Aero.
