Safran subsidiary Microturbo’s new e-APU60 auxiliary power unit received certification from the U.S. Federal Aviation Administration last month. It achieved European approval in May last year.
The APU, which has already been selected for the AgustaWestland AW189 helicopter, is designed to “meet the demands of new-generation more-electric aircraft,” according to Microturbo (Hall 4 Stand A7). In addition to ground starting the main engines, supplying power to the electrical systems and providing air conditioning for the AW189, the e-APU60 can restart the engines in flight and provides an additional source of power required to cover all electrical needs throughout the flightenvelope.
According to Microturbo, the e-APU60 delivers significant reductions in noise and emissions compared with conventional APUs. The company believes it will also be selected for use with fixed-wing business aircraft.
