Bell Helicopter has selected aerospace and defense industry filtration systems manufacturer Donaldson to provide engine protection on the 525 Relentless. Under the contract, Donaldson will begin supplying transmission oil filter assemblies for the main rotor gearbox, tail rotor gearbox, intermediate gearbox and reduction gearbox in 2014. The Bell 525 will also feature factor-installed options for inlet barrier filter (IBF) systems for protection of the Bell 525 Relentless twin GE CT7-2F1 engine and Honeywell RE100 auxiliary power unit. Prototypes of the new IBFs are currently in the design phase, with delivery scheduled for early 2014 in time for the first flight of the Bell 525 Relentless.
