Here at Heli-Expo’08, Aerospace Filtration Systems (Booth No. 4013) is marking the delivery of more than 3,000 inlet barrier filters (IBFs) for helicopters. The engine protection systems are in use worldwide on a wide array of commercial and military helicopters, with more than one million total flight hours combined.
While AFS currently sells the majority of its inlet barrier filters for military use, the company said it is expanding its product base and making gains on the civil side. AFS expects to receive FAA approval this year for filters for the Eurocopter EC 130, Bell 430 and AgustaWestland AW139, as well as EASA approval by year-end for IBFs for the AgustaWestland AW119, Bell 205 and Eurocopter AS 350.
The company’s system for the EC 130 recently entered the final test phase, with an FAA STC anticipated in the next two months. According to AFS, the IBF for the EC 130 features a sealed engine-intake plenum that replaces the inlet screens, sand filter or alternate barrier filter. The design uses the existing cowl with minimum modifications, including incorporation of an aft-facing bypass door.
Meanwhile, AFS and French aerospace company Le Bozec Filtration & Systems have teamed to offer IBFs in the European, Middle Eastern and African markets. Both companies design and manufacture filtration units for
commercial and military helicopters.
