Rolls-Royce’s Boeing 747 Flying Testbed aircraft takes off from Tucson International Airport on a test flight with a Trent 1000 engine that runs on 100% “sustainable aviation fuel”.

Rolls-Royce’s Boeing 747 Flying Testbed is at Tucson International Airport with a Trent 1000 engine that was filled with 100% “sustainable aviation fuel” during a test flight on October 15, 2021.

A recent flight test from Tucson was another small step towards a future where airplanes run on cleaner fuel made from animal fats and agricultural waste.

London-based engine maker Rolls-Royce conducted a flight test of a Boeing 747 test aircraft from Tucson International Airport, with one of its flagship Trent engines running on 100% low-carbon, sustainable biofuel and the other three RB211 engines operating Standard aircraft fuel.

Rolls-Royce said it worked with Boeing and alternative fuel maker World Energy to run the October 15 test on 100% “sustainable aviation fuel,” or SAF, which is made from non-fossil fuels like cooking oil, vegetable oils and animal fat , Municipal waste and agricultural residues.

The plane took off and flew over New Mexico and Texas before returning to Tucson Airport 54 minutes later, said Rolls-Royce, who has been testing engines at TIA for nearly a decade.

Initial results confirmed that there were no technical problems with the engine, “which provides further evidence of the fuel’s suitability for commercial use,” the company said.

SAF, which causes around 80% less CO2 emissions than conventional aviation fuel, is already used to a limited extent by airlines, as the regulations allow a maximum of 50% to be mixed with aviation fuel.
