Q

Explosive train

A

play train of combustible explosive elements arranged in order of decreasing sensitivity, inside a fuse, projectile, bomb, etc.

B. Fuse explosive train: May consist of a primer, a detonator, a delay, a relay, a lead in a booster charge, one or more of which may either be omitted or combined
C. Bursting charge train: if a burster charged is added to a fuse explosive train, it becomes a bursting charge explosive train
D. Propelling charge train: May consist of a primer, igniter or ignitor in charge, usually black powder, and any of the various types of propellants.

Q

Explosion

A

A. This is a rapid and violent release of energy.
B. a chemical reaction or change of state which is affected in an exceedingly short space of time with the generation of high temperature in generally a large quantity of gas.
Note: an explosion produces a shock wave in the surrounding medium. The term includes both deflagration and detonation.

Q

Explosive initiation : SHOCK

A

High explosives frequently require a severe shock to induce their explosion

the shock may be mechanical in certain initiating explosives

22
Q

Explosive initiation : INFLUENCE

A

A detonation of one explosive mass that detonates another without actual contact; also known as a “sympathetic detonation”

23
Q

Detonation

A

A definition is classed as an explosion

Note: it is a chemical reaction that propagates with such rapidity that the rate of advance of the reaction zone into an unreacted material exceeds the velocity of sound in the unreacted material. The rate of advance of the reaction zone is termed “detonation rate” or “detonation velocity”

24
Q

Deflagration

A

Very rapid combustion sometimes a company by flame, Sparks, and / or battering of burning particles.

Notes: deflagration, although classed as an explosion, generally implies the burning of a substance at less than the velocity of sound.

25
Q

Brisance

A

The shattering (shock force) effect associated with explosives.

26
Q

Blast effect

A

Destruction of or damage to structures and personnel by the force of an explosion on or above the surface of the ground

27
Q

Explosive sensitivity

A

Amount of energy necessary to initiate an explosive

28
Q

Flammability

A

The ease with which an explosive can be ignited by flame and heat

29
Q

Water resistance

A

The number of hours and explosive can be placed in water and still function

30
Q

Hygroscopicity

A

The ability of an explosive to absorb moisture from its surroundings

31
Q

Propellant

A

low explosive substance which through rapid burning produces gases at controlled rates that provides the energy necessary to propel ordinance

Note: that which provides the energy for propelling something; specifically, and explosive powder charge for propelling a bullet, shell, etc.
Propel it may come in liquid or a solid (powder or granular).

32
Q

Oxidizer

A

A substance that furnishes the oxygen for burning the fuel
Note: certain mixtures of fuel and oxidizers can be made to explode and these are considered to be explosives. however, a substance such as a fuel which requires an outside source of oxygen (and oxidizer), or an oxidizer which requires an outside source of fuel to explode, is not considered an explosive.

33
Q

Shaped charge

A

They charge shaped so as to concentrate its explosive force in a particular direction.
Produces a jet that is called the “Monroe effect”.

Must have some sort of standoff

34
Q

Standoff

A

the distance between the base of the charge in the linear of shaped charge ordinance in the target at the time of initiation

35
Q

Misznay-Schardin Effect

A

The acceleration of a solid in plate from the face of an explosive charge under detonation such that the end plate remains a solid and is usable as a missile.

36
Q

Munroe effect

A

the effect that is produced by a shaped charge. Once initiated produces a concentrated explosive jet, commonly used by explosive anti-tank (HEAT) munitions

37
Q

Types of explosions

A

A. Mechanical
B. Nuclear
C. Chemical

38
Q

Explosion type: mechanical

A

pressure inside a container overcomes the strength of that container causing it to rupture (examples, a steam boiler, and over-inflated toy or a balloon).

Note: a container is necessary

39
Q

Explosion type: nuclear

A

The splitting of an atom or by fusing atoms together; in either case energy is released in the form of heat and pressure.

40
Q

Explosion type: chemical

A

a chemical reaction or change in the state of a mixture; when acted upon by initiating Force converts to gases releasing energy in the form of heat and pressure.

Note: a container is NOT required

41
Q

Velocity of reaction

A

The velocity of combustion of explosives.

A. Gunpowder Burns at about 24 cm per second.

B. High explosives velocity of reaction is from 6500 feet (2000 meters) per second to 27900 feet (8500 meters) per second; any reaction velocity below this is deflagration (low explosives).

C. Low explosives burn or react between the speed of gunpowder and high explosives.

42
Q

Effects of an explosion

A 
A. Blast effect
B. Shockwave
C. Fragmentation effect
     (1) primary fragments
     (2) secondary fragments
     (3) firebrand
     (4) rogue fragments
D. Incendiary effect
E. Radiation effect
43
Q

Explosion effects - BLAST

A

Caused by the conversion of the explosives into gases with the release of energy.

This and fragmentation affect is what should concern EOCA’s has the most

44
Q

Explosion effects - SHOCKWAVE

A

Caused by the compression of air being pushed away from the point of detonation.

“Earthshock” is also fell below ground.

45
Q

Explosion effects - FRAGMENTATION

A

Will vary depending on the explosives and container used to contain the explosives.

Note - you must also consider the surrounding area as you still have the two types of fragmentation: primary and secondary

46
Q

Fragmentation effect - PRIMARY FRAGMENTS

A

Are associated with the munition primary case material -

we’re by the inner case surface is the immediate contact or directly coupled with the energetic explosive material.

47
Q

Fragmentation effect - PRIMARY FRAGMENTS

A

Are associated with the munition primary case material -

we’re by the inner case surface is the immediate contact or directly coupled with the energetic explosive material.

48
Q

Fragmentation effects - SECONDARY FRAGMENTS

A

Are not associated with you munition primary case material

 Example: debris/rocks
49
Q

Fragmentation effects - FIREBRAND

A

A projected hot fragment that transfers is thermal energy to the surrounding area.

50
Q

Fragmentation effects - ROGUE FRAGMENTS

A

unique components of fragmentation, such as bomb lugs and faceplates, May travel further than predicted; some fragments May travel to distance is greater than 10,000 feet.

51
Q

Explosion effects - INCENDIARY

A

Thermal heat is highest 6,000 degrees Fahrenheit

- - can be produced at the point of detonation, and at the precise time of detonation.

52
Q

Explosion effects - RADIATION

A

Only found a nuclear material in nuclear weapons. It may consist of particle as well as ray-type radiation from initial radiation and or fallout.

Note- the important nuclear radiation, from the weapons standpoint, are alpha and beta particles, gamma rays, and neutrons.
