Ordnance Release Testing

Dayton T. Brown, Inc. can help ensure that your payload is delivered accurately and reliably every time. Our team is responsible for first article, production lot, qualification, and associated testing and engineering support for mechanical and electrical armament and missile launching systems.

DTB can help you develop a customized test plan that combines testing across many specifications – environmental, dynamics, EMI/EMC, structural, and non-destructive. Some of the standards that we follow include:

*We participated in the development of MIL-STD-2088A, entitled, “General Design Criteria for Aircraft Bomb Rack Unit (BRU).” DTB provided insight regarding item operation and testing requirements as an expert in working with bomb racks for the tri-services.

(BRU) Qualification Testing

Bomb Rack Unit (BRU) Qualification Testing

DTB has performed first article, production lot, qualification, and custom investigative testing of bomb racks for manufacturers, the Department of Defense (DoD), and foreign military entities.

We have extensive knowledge and experience with most legacy ordnance release equipment, as well as newer designs, including the Small Diameter Bomb Carriage and other bomb racks and launchers for the F-22, F-35 (JSF), and MMA aircraft.

Testing normally includes the tests that are noted in MIL-T-7743 and MIL-STD-810, as well as their commercial equivalents.

DTB has a unique life testing facility that allows for the rapid fire of bomb racks and bomb rack components in a controlled environment. The facility also encompasses fully instrumented bomb rack firing pits, which record all firing characteristics, such as velocity, piston pressure (ejector force), reactionary forces on the aircraft, ejection piston pressure, lag time (point of last contact), hook first motion, current draw, and more.

With DTB’s data acquisition software, the pitch, roll, yaw, maximum ejector force, end-of-stroke velocity, and cartridge bridgewire burn time can be calculated and plotted on one graph or multiple graphs for easy analysis.

Qualification Testing

Missile Launcher Qualification Testing

DTB has performed numerous qualification and Safety of Flight test programs on missile launchers for the DoD and direct manufacturers. We have also qualified numerous missile body designs, including the Harpoon, Tomahawk, and other prototype designs.

DTB’s unique simulated missile launcher life testing facility is specifically designed to perform the life test requirement in all three axis for the LAU-7 and AIM 9 (Sidewinder) missile configurations. This facility can be easily modified to accommodate other missile launchers and platforms.

Bomb Rack Cartridge Qualification Testing

DTB has performed impulse cartridge performance evaluations for the US Navy and Air Force, as well as qualification tests for manufacturers and investigative programs for all entities.

DTB has a number of bomb racks on-site, as well as the data acquisition and knowledgeable personnel available for every aspect of qualification programs or investigative needs.

We have also designed and fabricated Universal Cartridge Test Apparatus (UCTA) machines for outside entities.

Connector Qualification Testing

Lanyard Quick Release Connector Qualification Testing

DTB’s new high speed lanyard disconnect fixture is a unique and completely customizable fixture that provides disconnect speeds up to 382 in./sec. within 6 in. During the simulated firing scenario, 10,000 data points/sec. are collected. The speed, slack of the lanyard, clocking of the keyway, and the angle of release are all set prior to the simulated ejection. The pull force, electrical disconnect, speed, and displacement are all captured during the release.

DTB has also implemented the ability to perform the ejections at temperatures within the range of -65˚F-220˚F.

As with all ordnance release testing, high speed video is available, including at various temperatures.

Qualification Testing

BRU Small Parts Qualification Testing

As with full BRU testing, DTB has performed first article, production lot, qualification, and custom investigative testing of individual small parts for manufacturers, as well as the DoD.

Testing normally includes the tests that are noted in MIL-T-7743 and MIL-STD-810, as well as their commercial equivalents and individual requirements for the small parts.

DTB has designed numerous fixtures, as well as life and endurance testing systems, in order to aid the government with streamlining costs for necessary repeat testing. We have also aided in reducing the amount of cartridges needed for a test, along with eliminating the need for full bomb racks for testing.
