Turbotech, a leading supplier of sustainable aviation solutions, has achieved a significant milestone by successfully running a scalable turboprop engine out of a cryogenic hydrogen tank. Their innovative hydrogen turbine propulsion system, validated through Ansys simulation, offers high efficiency and zero carbon emissions, catering to light aviation needs. By integrating Ansys across their designs, Turbotech creates a digital thread that enables cost and time savings in developing hydrogen propulsion systems. This breakthrough was made possible by Ansys Fluent™ fluid simulation software, which helped redesign turbine components for hydrogen use. Through the Ansys Startup Program, Turbotech became the first company to deliver a viable hydrogen-fueled turbine engine for small-scale passenger planes, VTOL vehicles, and drones. Turbotech's approach stands out for its scalability, ensuring a smooth transition to hydrogen fuel. By utilizing Ansys simulation, the company identified optimal nozzle designs for real-world testing, reducing prototyping costs and timelines significantly. The simulations provided critical predictions of flame shape and temperature, ensuring structural integrity even after extensive hydrogen burn tests. Moreover, Turbotech's work with Ansys solvers allowed them to run simulations efficiently without the need for large clusters, streamlining the design process. Chief Technology Officer of Turbotech, Guillaume Malet, emphasized the importance of Ansys in achieving their goals, stating that Ansys' reliability was crucial in retrofitting the turbine for hydrogen within a short timeline. This innovation aims to reduce carbon emissions in light aviation, empowering pilots to focus on flying while promoting environmentally friendly practices. Turbotech's success story highlights the potential of hydrogen propulsion in revolutionizing the aviation industry, with Ansys playing a key role in enabling this advancement.
