“each pair of teeth on the gearbox will transmit more power than an entire grid of Formula 1 cars between them.”…
Rolls-Royce announced that it has set a new record for the world’s most powerful aerospace gearbox, just months after testing began.
Paul Stein, Chief Technology Officer at Rolls-Royce, confirmed that the Power Gearbox had successfully reached 70,000 horsepower while on test at Rolls-Royce’s dedicated facility in Dahlewitz, Germany.
The Power Gearbox will play a central role in the company’s next-generation UltraFan® engine, helping to deliver improved efficiency over a wide range of thrusts.
Rolls-Royce’s Power Gearbox is designed to run all the way up to 100,000 horsepower. When running at maximum power, each pair of teeth on the gearbox will transmit more power than an entire grid of Formula 1 cars between them.
The Power Gearbox has a planetary design, with each ‘planet’ capable of holding the force of a Trent XWB engine at full throttle. It is designed to allow the shafts at the core of the engine to run at very high speeds while allowing the fan at the front of the engine to run at a slower speed.
The UltraFan engine, available from 2025, will feature:
-Maximum fuel burn efficiency and low emissions through a new engine core architecture
-Reduced weight through the use of Carbon Titanium (CTi) in fan blades and a composite casing
-Increased efficiency through the use of ceramic matric composites (CMCs) which are heat resistant and require less cooling air
-Efficient power for high by-pass ratio engines of the future through a geared design
