Rolls-Royce plans to use 100 percent sustainable aviation fuel (SAF) to power a Trent turbofan during ground tests as part of its UltraFan next-generation engine demonstrator program, the company revealed Thursday. The tests, if successful, would confirm that unblended SAF makes a significant contribution to improving the environmental performance of gas turbine engines, said the company.
