QUADRACTIC MODEL OF THERMODYNAMIC STATES IN SDF EXPLOSIONS
0 likes49 views
We have established the locus of thermodynamic states encountered in SDF explosions. For the detonation products gases, the locus is a composite CJ isentrope (with fixed composition below 1,800 K and equilibrium composition above 1,800 K). For the combustion products, the locus is the 10-bar equilibrium isobar. By CHEETAH code calculations we have proven that both the Detonation Products and the Combustion Products behave as calorically-perfect gases for temperatures below 3,500 K.

Sedlec Ossuary
The Sedlec Ossuary also known as the Church of Bones is one of the most unusual chapels you will see.
Saint Barbara is often portrayed with miniature chains and a tower. As one of the Fourteen Holy Helpers, Barbara continues to be a popular saint in modern times, perhaps best known as the patron saint of armourers, artillerymen, military engineers, miners and others who work with explosives because of her legend's association with lightning, and also of mathematicians.

This document discusses shock waves in solids. It begins by introducing the importance of studying how shock waves propagate in condensed substances like metals and water, both theoretically and practically. It then discusses how experimental investigations of solids under high pressures, which can be achieved through powerful shock waves, provide information about materials' properties. The rest of the document analyzes the thermodynamic properties of solids at high pressures and temperatures, focusing on how the elastic and thermal components of pressure and energy change with compression and expansion. It describes how interatomic forces lead to different compressibility in solids compared to gases.Popular About Explosives; ru to eng

There exist a lot of controversial issues around the subject of Scalar Waves (SW) and the purpose of this white paper is to take an innovative theoretical approach to prove and backup up existence of such phenomena. We basically define this wave as a Scalar Longitudinal Wave (SLW), whose existence derives from the More Complete Electrodynamic
(MCE) theory aspect of Maxwells classical electrodynamic equations. MCE falls into the Quantum Electrodynamics (QED) aspect of the Maxwells equations, in particular out of his four famous classical equations, our interest focuses on the one that is known us as Faradays Law of the Maxwells Equation set.
From a classical physics point of view, typically there are three kinds of waves:
1. Mechanical Waves (i.e. wave on string)
2. Electromagnetic Waves (i.e. E and B fields from Maxwell's Equations to deduce the Wave Equations, where these waves carry energy from one place to another)
3. Quantum Mechanical Waves (i.e. Using Schr旦dingers Equation to study particle movement)

Linear Shaped Charge (LSC) failures were experienced during customer incoming inspection acceptance testing six weeks after successful LAT at the manufacturer. The RDX desensitization was attributed to RDX recrystallization sometime after high density loading during assembly and after LAT at the manufacturer. To understand the cause of failure, RDX literature review, and test analysis are discussed. The 1976 GIDEP ALERT identifies the recrystalline solvent to be occluded acetone while the 1988 GIDEP ALERT identifies occluded cyclohexanone was the recrystalline solvent. This paper is based upon the 1988 investigation results.08 14-2018 Properties of Selected High Explosives, 2nd Edition

Classes of Explosives
According to their chemical reaction rate and resulting output characteristics, explosives are classified as low explosives and high explosives. There is no sharp line of demarcation between the two classes, and within each class there may be explosives of considerably different performance, since they are grouped
only according to reaction rate.
Low explosives, which deflagrate (burn) rather than detonate and propagate at velocities 1,000 meters per second (m/s) and less, include the propellants, pyrotechnics and initiating or primer explosives.
Examples are nitrocellulose, double base powder, smokeless powder, black powder, cordite and the metal oxidizer mixtures.
Explosives which detonate and propagate at velocities greater than 1000 m/s, are high explosives and include the secondary explosives RDX, HMX, HNS, DIPAM, TETRYL, DATB, TATB, PETN, TNT, most of their compositions, and the primary explosives lead azide and lead styphnate. This paper will not discuss the primary explosives.07 25-2018 "SOLID STATE FUEL-AIR EXPLOSIVES" (THERMOBARICS)

30.04.2013; On the testing ground of one of the largest weapon producer in Bulgaria, VMZSopot, SURT Technologies (SURT) made the final tests of SURT thermobaric compositions (A/H-TBX) with the best hardware available to extract the maximum data needed for proof of conception.
The results from comparative tests with different munitions (pure A-IX-1 and standard mash type TBX (RDX/IPN/Al) far exceeded expectations and thats the main reason to move it abroad to NATO.
A-IX-1 is a Russian explosive used in modern Russian military shells. It consists of 95% RDX, phlegmatized with 5% wax. It has a relative TNT effectiveness factor around 1.60 and has been in use since WWII by the Russian Army.05 29-2018 Thermobaric Relative Effectiveness factor

Following a deliberate advance across the northern Chechen plains in October through December 1999, the Russian Army closed on the Chechen capital city of Grozny and the foothills of the imposing Caucasus mountains. There, the advance stopped. The Russians began the new century with a renewed assault on Grozny. The Russians continued their deliberate urban advance and, after forty days of fighting, the smoking ruins of Grozny were theirs. Unlike the first battle for Grozny (in late 1994-early 1995) or the recapture of the city by the Chechens (in 1996), the Russians now used quantities of fuel-air weapons, along with iron bombs, surface-to-surface missiles with high-explosive warheads, massed artillery and tank fire. These flattened large sections of the city and crushed the opposing force.DETONATION AND COMBUSTION OF NEW HETEROGENEOUS COMPOSITE EXPLOSIVES CONTAININ...

Fuel-air mixtures are powerful volumetric explosives (FAE) that were developed at the end of World War II. FAE may virtually use any particulate combustible such as cornstarch powder, metal powders,
liquid hydrocarbons or boron hydrides and any type of combustible gases.
Dispersions or mixtures of these fuels with air thermally ignite at defined stoichiometry, temperature and pressure. Deflagration of such a system may transition to detonation by a number of
mechanisms effecting coherent energy release e.g. (SWAGER). However, transition to detonation of a fuel/air mixture requires supercritical size of the cloud appropriate stoichiometry, temperature and pressure of the system. Generally high temperatures and pressures further DDT and lead to reduction of critical size.

The committee's assessment of the present state of thermobarics research and testing in the United States is that it is relatively immature and not particularly well structured.a As discussed further below, the committee believes that this is a result of the following:
The speed with which the United States attempted to field a thermobaric munition clone for use in Afghanistan;
The inability and reluctance of the services to field new materials (hence, the redefinition of thermobarics to include Indian Head Explosive 135 [IH-135]);
The unclear definition of terms;
The lack of careful analysis and experimentation;
Inadequate diagnostics that have perpetuated the reliance on anecdotal evidence as opposed to data; and
Testing against varied types of targets and unclear scale effects.NUMERICAL SIMULATIONS OF THERMOBARIC EXPLOSIONS

A Model of the energy evolution in thermobaric explosions is presented. It is based on the two-phase formulation: conservation laws for the gas and particle phases along with inter-phase interaction terms. It inc01porates a Combustion Model based on the mass conservation laws for fuel, air and products; source/sink terms are treated in the fast足chemistry limit appropriate for such gasdynamic fields. The Model takes into account both the afterbuming of the detonation products of the booster with air, and the combustion of the fuel (Al or TNT detonation products) with air.THERMOBARIC AND ENHANCED BLAST EXPLOSIVES PROPERTIES AND TESTING METHODS

Thermobaric explosives (TBX), similar to fuel air explosives (FAE), rely on the rapid combustion of liquid or solid fuels with high heats of combustion to generate relatively long duration
blast overpressures to defeat targets. When a conventional high explosive (HE) is detonated, a high pressure, short duration shock wave is created. The resulting impulse (integral of the pressure-time
curve) of such a detonation is fairly low. In comparison, a TBX or FAE detonation generates a lower pressure, longer duration blast wave. The longer duration blast wave results from combustion of the thermobaric fuel additives which occur on a much longer time scale (milliseconds) than the detonation
event (microseconds).MSIAC:L 165 volumetric explosives part 1, fuel-air explosives
