Rolls-Royce has achieved a significant milestone in its quest for carbon-free aviation by successfully running a modified jet engine, using hydrogen as its primary fuel source at takeoff power. This accomplishment marks a crucial advancement in developing environmentally sustainable aircraft propulsion systems.
The test involved overcoming substantial engineering challenges, as hydrogen burns at higher temperatures and speeds compared to traditional kerosene. Rolls-Royce conducted these tests using a modified Pearl 700 engine, with newly developed fuel spray nozzles that carefully mix hydrogen and air at precise ratios to control the combustion process.
The next step involves conducting a full ground test to further refine this groundbreaking technology. This research effort is a collaborative initiative led by the UK Hydrogen in Aviation alliance, consisting of various companies and academic institutions, with easyJet and Rolls-Royce at the forefront.
Grazia Vittadini, Chief Technology Officer at Rolls-Royce, expressed enthusiasm, stating, "Controlling the combustion process is one of the key technology challenges the industry faces in making hydrogen a real aviation fuel of the future. We have achieved that, and it makes us eager to keep moving forward."
