Prof Sergey Karabasov from Queen Mary University of London (QMUL) and UK-based CAE software company GPU-Prime, backed by leading aerospace OEMs, advanced air mobility companies and UK universities, have been awarded a grant towards the total project cost of £617k through the ATI Programme, which supports technology innovation in the UK aerospace supply chain.

The GPU-accelerated Unsteady Simulations for Turbulent Flow and Aeroacoustics (GUSTFAST) R&D project will deliver a memory-efficient, GPU-native Large Eddy Simulation (LES) toolchain for unsteady aerodynamics and aeroacoustics, enabling earlier, faster and more cost-effective design decisions in aerospace programmes. It combines GPU-native algorithms based on the CABARET method with AI-driven optimisation and template-based pre- and post-processing workflows tailored to specific aerospace applications.

High-fidelity LES remains underutilised in industrial aircraft and propulsion design. As regulatory requirements tighten and new platforms mature, OEMs and SMEs need reliable and scalable tools to predict unsteady flow and aeroacoustic interactions earlier in the design cycle.

GPU-Prime, with support from QMUL, has been developing GPU-native LES technology for aerospace applications for many years, validating it with industry partners as well as through EU Horizon 2020 and AeroAcoustics Research Consortium (AARC) projects.

The ATI Programme SME funding will accelerate development and delivery of a CAE software suite optimised for critical aerospace applications. The ATI Programme is delivered in partnership between Aerospace Technology Institute, Department for Business, Innovation, Science and Trade, and Innovate UK.
