IAC
Noishield® Run-up Pens are cost-effective in suppressing aircraft
noise, and in providing secured test areas. With ease of operation
and minimum running costs, they can accept a multiplicity of aircraft
with one or several engines in single or multiple modes.
IAC Noishield® Run-Up Pen reduces sound pressure levels of
B-1B Bomber to less than 95 dB(A) at a distance of 328 ft (100
m) without affecting engine performance
Highly
sound-absorptive Noishield® Barrier Modules, engineered
to an appropriate height, developed by IAC for this application,
are the key to run-up pen noise-control performance. Also, the
facility is designed to accept the thermal structural shock
from high mass flow jet engines operating at afterburner temperatures.
To enhance the useful life of barrier panels, engineering features
have been incorporated to protect the acoustical infill against
erosion due to thermal stresses, vibration, and gas flow turbulence.
IAC Noishield® Barrier Modules offer cost - effective solutions
for isolating noisy airport areas
Noishield®
Run-Up Pens provide 10 to 12 dBA noise reduction and have no
adverse effect on engine performance.
IAC Modular Blast Fences are available in "hard" non-absorptive
sections or with "soft" sound-absorptive characteristics
which help reduce noise build-up.
The sound-absorptive blast deflector design incorporates a structural
framework with barrier modules installed to permit thermal expansion.
Panels are protected against infill erosion by stainless steel
screens and expanded metal deflectors to ensure long life.
Run-ups of fighter aircraft at all power settings in confined
locations are facilitated with IAC Blast Fences
Non-absorptive
sections are fabricated from formed steel components arranged
to direct exhaust gas flow away from critical areas. Recommended
for locations where the aircraft will be positioned in close
proximity to the blast deflector, these hard sections can be
designed to withstand afterburning jet engine blasts exceeding
35,000 lb (15,000 kg) thrust at distances as close-in as 50
ft (15 m).
All IAC Blast Fences are demountable, permitting disassembly
for relocation and reassembly without loss of structural or
acoustical properties. Depending on desired life expectancy,
IAC Blast Fences can be fabricated from either carbon or stainless
steel.
