17
Q

What are the 5 EOD procedures

A

  • Disposal procedures
18
Q

What are the two types of explosive train?

A
  • Igniferous

- Disruptive

19
Q

What is the monroe effect?

A

When detonating an explosive with a cavity at the target end, a jet of gases is formed which concentrates energy onto the target adjacent the charge. Improved with a liner and stand-off

20
Q

What is the misnay-schardin effect

A

A dish shaped liner at the end of a cylindrical explosive that forms an Explosive Formed Projectile, the projectile does the penetration

21
Q

What are the 4 types of solid propellants?

A
  • Single (NC
  • Double (NC, NG)
  • Triple (NC, NG, Nitroguanidine)
  • Condensed (polymer matrix)
22
Q

What are the two types of liquid propellants their their subcatergories?

A

Monopropellants

  • Monergols
  • Catergols

Bipropellants

  • Hypergolic
  • Non hypergolic
23
Q

What are some pyrotechnic functions? (DIISST)

A
  • Delays
  • Incendiaries
  • IIlluination
  • Signal
  • Sound
  • Tracking
24
Q

What is exudation?

A

Impurities in the explosive filling which melt and exude from the body of the filling

25
Q

What is extrusion?

A

The thermal expansion of HE filling which forces the sealing composition out through the body

26
Q

What are some HE fill techniques?
