High explosive materials
Web21 de jul. de 2024 · High-explosive (HE) materials (e.g., PETN, RDX, C-4, or TNT) were used to prepare contaminated fingerprints. These were subsequently deposited on various objects, including microscopic glass slides, a table, a mug, etc. Samples deposited on glass slides were directly sent for analyses; for other samples, adhesive tapes were used to lift … WebWe have designed and demonstrated a standoff Raman system for detecting high explosive materials at distances up to 50 meters in ambient light conditions. In the system, light is collected using an 8-in. Schmidt-Cassegrain telescope fiber-coupled to an f/1.8 spectrograph with a gated intensified cha …

WebIn order to produce a nuclear explosion, subcritical masses of fissionable material must be rapidly assembled into a supercritical configuration. The simplest weapon design is the pure fission gun-assembly device, in which an explosive propellant is used to fire one subcritical mass down a “gun barrel” into another subcritical mass. Plutonium cannot be used as the …

Web26 de nov. de 2024 · Low explosives are mixtures of chemicals that burn very rapidly, but subsonically (as opposed to supersonically), meaning that they “deflagrate.”. They consist typically of fuel and an oxidizer. High explosives consist of materials that typically combine the reacting elements in the same molecule.
In explosives engineering, sensitivity refers to the degree to which an explosive can be initiated by impact, heat, or friction. Current in-use standard methods of mechanical (impact and friction) senstivity determination differ by the sample preparation (constant mass or volume is usually used; pile or pressed pellet), sample arrangement (confined/unconfined sample etc), instrument type, go/not go criteria, and the statistical analysis of results. WebRDX is a cost efficient, powerful high explosive produced in large industrial quantities. As a relatively insensitive, stable, and safe-to-handle energetic material, it is useful in a variety of applications -- both for military and civilian end products.
Webexplosive, any substance or device that can be made to produce a volume of rapidly expanding gas in an extremely brief period. There are three fundamental types: mechanical, nuclear, and chemical. A mechanical …
