The test is the culmination of a four-year programme to prove hydrogen's potential as a future aviation fuel. Operated using 100% hydrogen, the modified engine completed a flight cycle demonstration, including take-off, cruise and landing.

As Rolls-Royce's engineering partner, TCS provided engineering expertise that helped fast-track the development, testing and successful delivery of the hydrogen propulsion programme, the firm said. TCS supported Rolls-Royce in critical areas including fuel system and engine controls integration, hydrogen combustion analysis, test preparation, validation, data analytics, risk management, and detailed design.

Adam Newman, Chief Engineer, Hydrogen Demonstrator Programme, Rolls-Royce, said, "The programme marks an important milestone in our journey towards more sustainable aviation. Through a rigorous and carefully staged testing approach, we have gained valuable insights into how 100% hydrogen behaves in a modern aero gas turbine across a full flight cycle, while validating critical combustion, fuel and control system technologies."

Anupam Singhal, President - Manufacturing, TCS, said, "The milestone reflects what becomes possible when advanced engineering is combined with digital capabilities and deep ecosystem collaboration to move breakthrough innovation closer to the real-world."
