Engine manufacturer Rolls-Royce announces that its UltraFan engine is ready for full-scale testing at its Derby dyno in the UK. This huge reactor should reduce fuel consumption by 25%.

Engine manufacturer Rolls-Royce has just announced that it is ready to test its demonstratordemonstrator ultrafan since the beginning of the year 2023. For these tests, it was placed on their gigantic custom-built dyno at Derby in the UK in 2020. This turbojet double flow at high dilution, called “zero CoalCoal it is the largest ever built. your entrance toairair measures 3.55 meters and its huge blades in alloyalloy The carbon-titanium engines are expected to be 25% more fuel efficient than the engine manufacturer’s first-generation Trent family jet engines.

During early testing of its gearbox, the UltraFan’s power was measured at 87,000 horsepower or 64 megawatts, enough to supply EnergyEnergy a city of almost 100,000 inhabitants. This engine was not developed to equip a particular aircraft, but to test large-scale technologies that can be exploited for specific aircraft in the future.

10% less consumption

For its tests, it will be powered by 100% sustainable aviation fuel. Initially, the idea is, therefore, to improve the Trent reactors to reduce their consumption in Gasoline and, in fact, the emissionsemissions of CO₂. Combining this technology with architectures of fuselagefuselage optimized, the reduction could reach 10%. A rate that does not seem particularly impressive but which, in the volumevolume flights, presents a impact important. The development of these technologies is not for tomorrow, however, because we will have to wait until the 2030s to start seeing these types of devices fly. On the other hand, certain technological bricks should land in the current engines and in particular in the most recent A350s.
