Fire suppression funnels in use at Edwards Air Force Base save thousands
of dollars in labor costs and are better for the environment.
AIRCRAFT HANGAR fire suppression systems must duct tape. According to Mary Parker,

How it Works
for days. Steve Bridgers, JT4, JSF supervisor, Facility Bridgers and Hudyma designed the
Engineering for Edwards Air Force Base and Mike fire suppression funnels to fit over the
Hudyma, president of SCS Interiors, solved this foam generators and direct the liquid
to 12-foot by 12-foot ponds made from

The foam generators dump the solution

into the six-foot by six-foot funnels
Foam generators at the top of a
hangar mix soap and water during a fire
suppression test. Water pressure drives a
mechanical fan that blows air across a
diffuser. This creates foam that is dumped
onto the hangar floor until the building
is filled 15 to 20 feet high.
Preparing for this messy test requires
airport hangar employees to tape plastic
over all the hangar systems and power
stations, which is a long and expensive
process. Prepping a hangar in this manner
takes many man-hours and hundreds of
feet of plastic covers and duct tape.

" That would take an enormous
labor to accomplish for a hangar that
supports six jets. We estimated that flight
operation would stop for a minimum of
three to four days, " Bridgers commented,
citing that Edwards Air Force Base
has three hangars where this testing is
conducted.
Bridgers came up with an idea to
create fire suppression funnels which
channel the fluid into containment ponds,
saving the base time and money. The
hangar does not need to be shut down
to be prepped with plastic covers and

long tube, which runs into the ponds,
capturing the water.
The hoses are similar to highpressure air hoses used to deliver
conditioned air to an aircraft. The hoses
are made of reinforced PVC fabric, " and
the coating on that fabric when it's heated
and pressed together, it welds itself into
one continuous tube, " Hudyma said.
" They're kind of the same concept, one's
delivering air, one's delivering water. "
After the fire suppression test, an
