MIL-S-901D Barge Test Video at Moment of Explosion. The barge test or heavyweight test requires the item under test to be mounted on a floating barge. For the standard floating platform, 60 pounds (27 kg) of HBX-1 explosive is placed 24 feet (7.3 m) underwater at various distances from the barge and detonated. There are four 'shots'.
This was achieved through laboratory shock testing of equipment prior to its installation aboard vessels. With the advances in computer simulation and modeling capabilities, it is now possible to simulate a vessel's response to an underwater explosion and to identify potential problems or failures without extensive field testing. By using DDAM ...
Each "Sailor Hat" test at Kahoʻolawe consisted of a dome-stacked 500-short-ton (454 t) charge of TNT high explosive detonated on the shore close to the ships under test. Since a TNT detonation releases energy more slowly than a nuclear explosion, the blast effect at close range was designed to be equivalent to a 1 kiloton of TNT (4.2 TJ ...
In mechanics and physics, shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity).
The two most common sensitivity test and analysis methods are the Bruceton analysis and Neyer d-optimal test. These methods allow the user to determine the 50% initiation level (the distance at which 50% of the samples will "go"), and a standard deviation. Impact testing may also be performed with liquid samples confined in special cells.
Several key aspects of the second flight test went to plan: When the rocket took off from the SpaceX Starbase launch site in Boca Chica, Texas, just after 8 a.m. ET, it was able to ignite all 33 ...
Shock factor is a commonly used figure of merit for estimating the amount of shock experienced by a naval target from an underwater explosion as a function of explosive charge weight, slant range, and depression angle (between vessel and charge).
Earlier, Chinese state media said an explosion was reported at the port and shockwaves were felt a kilometre away. Yang Ming Marine Transport said a fire occurred on board the YM Mobility while it ...
