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.

Catapult and Arresting Gear Simulation

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.

We also have 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.



DTB is certified under the National Security Agency (NSA) TEMPEST Endorsement Program to provide TEMPEST testing services:


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 Bellcore GR-63 Zone 4 Seismic Vibration requirements.

Seismic Vibration Testing

The systems are also used for all types of Mil-Std tests. An example is the shipboard test requirement of Mil-Std-167-1.

Seismic Vibration Testing

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.

Large Overload Structural Testing

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.

Optics and Laser Eye Protection Testing

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.

Helicopter Parts Testing

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.
