Turbotech, in collaboration with Ansys, has made significant strides in advancing hydrogen-fueled light aviation. Utilizing Ansys simulation, Turbotech has successfully developed a hydrogen turbine propulsion system that not only operates efficiently but also produces zero carbon emissions. By integrating Ansys across their designs and leveraging tools like Ansys Fluent™ fluid simulation software, Turbotech has been able to optimize turbine components for hydrogen, thus streamlining the transition to this eco-friendly fuel. Through simulation-led product development, Turbotech identified the best nozzle designs for testing, reducing prototyping costs and timelines. Ansys solvers facilitated these simulations, enabling efficient testing without the need for large clusters. The successful retrofit of the turbine for hydrogen highlights the effectiveness of the partnership between Turbotech and Ansys. The collaboration, supported by the French Civil Aviation Authority, has been instrumental in showcasing the viability of hydrogen propulsion in light aviation. The BeautHyFuel project, led by Turbotech and Elixir Aircraft, with partners like Safran, Air Liquide, and Daher, demonstrates a joint effort towards sustainable aviation solutions. The positive sentiment towards hydrogen in this article is evident through the emphasis on reducing carbon emissions and the efficiency of hydrogen-fueled turbines.
