HANGAR TALK The Donaldson IBF reduces engine


turbine operating temperatures, makes more power available for missions and reduces maintenance when compared with other power plant protection options. It also extends engine life by eliminating component erosion. These benefits enable operators to realize substantial cost savings and improve “time on wing” for helicopter power plants.

Donaldson Debuts Inlet Barrier Filters at IDEX and Marks Milestone Black Hawk Delivery


Donaldson Aerospace & Defense


highlighted its Inlet Barrier Filter’s abili­ ty to protect military and civil helicop­ ter power plants from catastrophic fail­ ure and other hazards during its first­ ever display of this system at the International Defence Exhibition and Conference (IDEX). The debut of the Inlet Barrier Filter


(IBF) at IDEX 2013 comes as Donaldson Aerospace & Defense, a division of Donaldson Company, Inc., marks a mile­ stone for the system. It has delivered the 500th IBF for the U.S. Army’s work­ horse H­60 BLACK HAWK helicopters. Donaldson’s display at IDEX 2013 with Continental Aviation Services, included IBFs installed on an H­60 and a Bell Helicopter 407. “The Middle East’s routine high tem­


peratures and intense dust and sand conditions demand highly effective means of protecting helicopter engines from severe failure and performance

degradation,” said Eric Erickson, General Manager of Donaldson Aerospace and Defense in St. Louis. “Our Inlet Barrier Filters deliver this essential protection, helping operators to ensure the reliability and safety of critical missions and reduce mainte­ nance requirements and life­cycle costs.”


IBF­equipped BLACK HAWKs fly such


key missions as air assault, air cavalry, aeromedical evacuation and special operations for the U.S. Army, the UAE Air Force and Royal Saudi Air Force. The U.S. Army has fitted more than 25 percent of its BLACK HAWK fleet with Donaldson IBFs, which are also designed for the U.S. Navy’s H­60 SEA­ HAWK fleet. The Bell 407 serves military and civil­


ian operators around the globe, flying missions that include medical evacua­ tion, patrol, reconnaissance and trans­ port. The Iraqi army, for example, is currently expanding its fleet of armed scout 407s. Donaldson IBFs help the crews of


these and many other helicopter types – including the AgustaWestland AW109E/S/SP and AW139 and the Eurocopter AS350B3e – execute their missions safely and reliably in the world’s dirtiest, most dangerous environments.


AgustaWestland at Aero India 2013 AgustaWestland recently showcased


its range of modern high performance military and commercial helicopters at Aero India 2013, which was held at Air Force Station Yelahanka, Bengaluru, from 6 ­ 10 February. Helicopters pro­ moted at Aero India included the AW101, 12 of which are now in the process of delivery to the Indian Air Force for government transport duties. Other helicopters to be featured includ­ ed the AW109LUH light twin­engine mil­ itary helicopter, the best selling AW139 12­15 passenger medium­twin engine helicopter and the naval variant of the NH90 helicopter.
