Honeywell Tapped for Bell 525 APU, Environmental Controls

Bell Helicopter has tapped Honeywell to provide the auxiliary power unit (APU) and environmental control system for the new Bell 525 Relentless, which is scheduled to start flying next year. The Honeywell RE100 APU selected for the super-medium twin helicopter is lighter and more fuel efficient than competing systems, according to Honeywell. Honeywell’s AC-5510 environmental control system will provide heating and air-conditioning for the 16-passenger helicopter.
