Donaldson Aerospace & Defense is working with AgustaWestland to design, develop and produce Inlet Barrier Filter (IBF) systems to protect AW189 helicopter engines and auxiliary power units (APUs) from dirt, dust, salt and foreign objects. EASA certification is expected in spring 2016, and will keep contamination from degrading the performance and reliability of its two, 2,000 shp General Electric CT7-2E1 turboshaft engines.
Matt Fortuna, general manager of Donaldson Aerospace & Defense said “With the AW189, AgustaWestland has succeeded in bringing longer range, higher capacity and greater endurance to critical missions such as offshore oil and gas support and SAR. Donaldson is pleased to work with this leading aircraft maker to ensure the highest performance and reliability of these aircraft on those missions”.
Donaldson already has received certification of an IBF installation on the AW139 from the FAA, EASA as well as ANAC in Brazil. The IBF offers significantly better engine protection and performance with minimal installation impact. For the AW139, it includes two low-drag, conformal fore and aft fairing assemblies with two filters per side that are removed easily for fast filter exchange. Those assemblies are mounted on existing engine doors to create sealed intake plenums.
