Honeywell To Supply APU, Environmental Control System for Bell 525 Helicopter

Bell Helicopter has tapped Honeywell (Booth No. C4304) 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 55 pounds lighter and 27 percent smaller than competing systems, according to Honeywell. This is the first rotorcraft application for the Honeywell APU, which allows operators to run critical avionics and electronics systems without turning on the main engine. Honeywell’s AC-5510 environmental control system will provide heating and air-conditioning for the 16-passenger helicopter while on the ground and in the air.
