Honeywell Helps Bell 525 Power Up for First Flight

Honeywell Aerospace technology helped get the Bell 525 Relentless off to a great start when the helicopter made its first flight on July 1. We provide several essential mechanical systems for the new super-medium helicopter, including the auxiliary power unit (APU), air turbine starter (ATS) and other components. Pilots use the APU and ATS to start the helicopter’s main engines.  The APU also provides power, main engine start and enables cooling while the aircraft is on the ground.

The successful first flight took place at Bell Helicopter’s aircraft assembly center in Amarillo, Texas. According to Bell test pilots, the aircraft performed “extremely well” during a test flight that included taxi testing and maneuvers and various hover maneuvers. Flight testing continues as Bell works toward certification. The company has more than 60 letters of intent to purchase the aircraft.

The Bell 525 is the world's first fly-by-wire commercial helicopter designed to operate safely and reliably in austere environments with a decreased pilot workload. It features best-in-class payload, cabin and cargo volumes. The helicopter is designed to perform a wide variety of missions under challenging operating and weather conditions and is considered ideal for oil and gas exploration and production operations.

Honeywell systems for the Bell 525 are based on proven helicopter technology. The company is a leader in developing mechanical technologies for commercial and military helicopters, including a full line of reliable lightweight APUs and starters. Honeywell also is providing the environmental control system and starting valves for the Bell 525. Other systems, including navigation and communication radios and advanced weather radar, are available as options or upgrades for the helicopter.
