Enhanced Windblast Test Facility
For over forty years, Dayton T. Brown, Inc. has been providing windblast testing
services to evaluate aircrew safety during emergency aircraft egress.
The windblast facility produces a high velocity air flow field similar to the aerodynamic environment external to the aircraft. This is accomplished with the controlled expansion of high pressure compressed air which exits from a rectangular nozzle.
Upon exiting the nozzle, the air impinges on the item under test, which is mounted on the positioning turntable. The dynamic effects on the test item are recorded with high speed video cameras and electronic data transducers for subsequent analysis.

Testing Facility.
Catapult and Arresting Gear Simulation
Aircraft Carrier Catapult Testing at DTB
DTB is a center of excellence in the area of testing, inspecting and qualifying
aircraft catapult and arresting gear, including both aircraft and shipboard components.
Tests conducted include life extension fatigue tests for the arresting gar of the
EA-6B, F-18 C/D, S-3, E-2C and C-2A aircraft.
These tests include arresting gear
load spectrum development, damage tolerance analysis, corrosion pitting analyses,
and striation counting on fracture surfaces to determine crack initiation life.
DTB also performs conformance inspections on arresting gear hookpoints, stingers,
launch bars and carrier arresting gear engine components.
These inspections included
dimensional and metallurgical inspections including hard coat face evaluations.
In Addition, DTB has an extensive inventory of loading adapters and fixtures used to proof
load test these components. Our personnel are familiar with the exacting requirements
of catapult and arresting gear and the demands that are placed on them in service.
Tempest
DTB is certified under the National Security Agency (NSA) Tempest Endorsement Program
to provide Tempest testing services.
www.nsa.gov/ia/industry/tempest/TestServicesEndorsed.cfm?MenuID=10.2.1.3.3
DTB can perform testing in accordance with a variety of requirements including NSTISSAM
and AMSG specifications. With over 20 years of Tempest experience, DTB can provide
a full range of support, from proposals, to control and test plans, laboratory and/or
field testing, failure analysis and corrective action, and installation guidance.
Seismic Vibration Testing
Our Vertical and Horizontal seismic vibration facilities, manufactured by the Team
Corporation, offer low frequency high displacement vibration capabilities to meet
the Belcore GR-63 Zone 4 Seismic Vibration requirements.
The systems are also used for all types of Mil-Std tests. An example is the shipboard
test requirement of Mil-Std-167-1. Since DTB maintain a hydraulic system in the
laboratory supplying over 600 gpm both the vertical and horizontal vibration facilities
can be run together. This results in test programs being processed through the laboratory
in a very timely manner.
Large Overload Structural Testing
DTB has reconfigurable large overload frames that can be used to quickly and efficiently
structurally test your item. These frames, which measure 32’ x 16’ x 12’ have been
used to test aircraft wing pods, truck suspensions, armament systems and more. All
jack and reaction locations are continuously adjustable.
DTB has an extensive array of attachment fixtures, clevises and adapters to allow a
cost efficient setup. Using our load
control systems and data acquisition systems we can load your item properly and give you
the data you and your customer require.
Optical Properties Verification
Dayton T. Brown, Inc. has wide ranging experience in the propagation
and measurement of electromagnetic radiation in the visible, infrared and ultraviolet
regions.
We maintain a particular interest and capacity with respect to laser eye protection.
Our capabilities include the measurement and evaluation of laser eye protection
for helmet mounted displays, night vision goggles and Integrated Modular Helmets
in accordance with the latest military specifications in the visible, near infrared
and infrared regions.
In addition to this proficiency, we also maintain the facilities and equipment necessary
to evaluate photometric attributes of light. We retain the expertise to evaluate
displays and light sources for Chromaticity, Luminous Intensity, Luminance, Illuminance,
Spectral Response and Contrast Ratios.
Helicopter Parts Testing
DTB has alternate source fatigue tested over 100 different critical safety items
for the US Army AMCOM. Alternate source parts must meet the same fatigue life testing
requirements as the OEM components. Examples of this type of testing include the
UH-60 Rotor Cuff, CH-47 Swashplate, CH-47 Horizontal Hinge Pin.
For these programs DTB develops, as required, the loading methodology, test fixture
design, test plan development and fixture fabrication. To verify proper loading
twp, previously qualified components are tested first and their failure compared to
existing data. Metallurgical examinations confirm failure modes and insure that
the proper areas of the component are being “challenged”.
Two alternate source components are then tested and their results compared to the
previously qualified components data. A final test report including metallurgical
examination is provided to AMCOM for their evaluation.
Below is a list of components
that DTB has fatigue tested as part of alternate source qualification testing. Check
with us for other components not specifically listed as they may be capable of being
fatigue tested using existing test fixtures used for the parts listed below.
