The AgustaWestland AW189 medium twin helicopter will be the first civil application for Microturbo’s e-APU, an auxiliary power unit that delivers essentially electric power. The e-APU60, which will deliver 60 kilowatts for the helicopter’s systems, offers benefits in safety, fuel burn and overall aircraft design, according to Microturbo.

The Toulouse-based equipment manufacturer would give details only for the military, shorter version of the AW189, the AW149, but AIN understands they also apply to the AW189. The e-APU will provide power for de-icing and engine start. It can operate far above any helicopter’s ceiling, at up to 51,000 feet.
