Aerospace Filtration Systems, Inc. (AFS) has received an STC
and PMA from the FAA for an Inlet Barrier Filter (IBF) system for
Bell 205A1/UH-1H series helicopters. This first-ever certified high
performance filter for the Bell 205A1 allows operators to maximize
engine protection while reaping performance and maintenance
benefits utilizing proven technology.
This new IBF features interchangeable filters and a new, sealed
engine intake plenum engineered to replace the lower performance
inertial particle separators or FOD screens. "Our goal was to
provide a new system with minimum installation impact, better
performance, and improved maintenance provisions for drive shaft
and engine inlet access," said Michael Scimone, president of
AFS.
"Operators working in the typically rugged environments where
the Bell 205A1 and UH-1H fly will realize more power, reduced
flight restrictions and lowered engine maintenance costs."
Scimone said the new STC/PMA filter system can assist helicopter
operators with a protection capability not previously available for
a variety of mission applications, such as remote seismic and
energy exploration work, desert operations, fighting fires, as well
as urban flight operations. The new IBF filters out more than 99
percent of dirt, sand, ash, and fine particulates, ensuring the
engine has the maximum protection possible for any mission scenario
and allowing peak power through to Time Between Overhaul (TBO).
Recognizing the important roles of the venerable Bell 205A1 and
UH-1H in utility, firefighting and military operations, AFS
leadership believed this storied aircraft deserved the best
technology available for the current missions it performs. Bell
205s and UH-1Hs continue to be the workhorses of choice in many
categories, with a diverse operator base. The new AFS IBF has been
chosen by the U.S. Department of State for its toughest UH-1H Huey
II missions with aircraft already in operation and proven
results.
Barrier filter technology applied to turbine engine inlets
provides a substantial return on investment (ROI) for operators. In
most cases, turbine engine components are life-limited parts, but
seldom reach their design lives.
With a barrier filter installed, these expensive components are
able to survive multiple overhauls. The ROI for a barrier filter
system is easily attained within one engine overhaul cycle, even in
a relatively clean environment. IBF protected engines are expected
to make TBO without erosion damage.
