Honeywell has completed initial testing of renewable jet fuel on its 131-9 Auxiliary Power Unit (APU) and TFE 731-5 turbofan engine, with results comparable to traditional aviation fuels.
An APU is a small gas-powered turbine engine that provides bleed air for main engine starting and electrical power for cockpit and galley systems. The 131-9 is the most commonly used APU for single-aisle commercial transport aircraft. The TFE 731-5 powers a variety of medium and large business jet aircraft.
The renewable jet fuel was produced using technology from Honeywell
