High Performance System Helps Prevent Engine Damage
Aerospace Filtration Systems has
received an STC from the FAA for an Inlet Barrier Filter (IBF)
system for the AgustaWestland AW139. This new IBF prevents engine
damage in adverse and ramp environments alike.
Donaldson's Aerospace and Defense Group, Aerospace Filtration's
parent company, partnered with AgustaWestland to ensure the system
addressed the AW139's operational requirements. After successful
joint development of the IBF for the AW119 series, Donaldson's
engineering department worked closely with AgustaWestland's
technical team to refine the AW139 IBF design.
"Listening to our customers' needs and providing second-to-none
customer support is critical to our team," commented Mike Scimone,
President of AFS. "Responding to operators and AgustaWestland
priorities, we came up with a plan to provide an expedited and
superior engine protection solution."
The new AW139 IBF system features low profile conformal fore and
aft fairings with dual filter assemblies mounted on the existing
engine doors, creating a sealed intake plenum. As with all
certified Donaldson IBF's, the AW139 system includes an alternate
inlet air bypass system. This emergency bypass capability is an
important IBF feature and is absent in most traditional sand
filters and particle separators. A simple compact cockpit switch
allows indication and activation of the bypass system. An integral
Filter Maintenance Aid also allows for on-condition inspections
pre- and post-flight to assist in mission planning and visual
inspection of filter condition.
