(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.
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.
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, MIL-STD-810, and MIL-S-4040, 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.
