Expedient Charges

Question 1

explain a expedient shaped charge

Answer 1

produces tubular or linear fractures, the monroe effect

plastic explosives are best suited

Question 2

what is the angle of cavity for expedient shaped charge and what is the stand-off

Answer 2

45-60 degrees, 42 is optimum

stand-off is 1.5 times the base of the cone

Question 3

what is the formula for expedient shaped charges

Answer 3

determine the volume of cylinder

v = 3.14 x radius(cubed) x height of explosives

v = determine the volume of the cone

3.14 x radius(cubed) x 1/3 height of cone

subtract v of cone for v of cylinder

then divide by CV of explosive

Question 4

explain a expedient platter charge

Answer 4

produces a powerful blunt-nose projectile, the miznay-chardin effect

Question 5

how much should the plate weigh for expedient platter charge and how much explosives

Answer 5

between 2-6 pounds

amount of explosives = weight of plate

Question 6

explain the expedient grapeshot charge

Answer 6

consist of a metal container, steel projectiles, buffer material and plastic explosives

Question 7

how much explosives for a grapeshot charge

Answer 7

explosives = 1/4 the weight of the projectiles

Question 8

what is a dust initiator charge

Answer 8

consists of a incendiary/explosive mix, a finely-divided organic material(dust) or a volatile fuel called surround

Question 9

how much explosives in a dust initiator

Answer 9

1 pound of base charge will detonate up to 40 pounds of dust(cover)

Question 10

what is the dust initiator formula

Answer 10

determine cubic volume of building

divide by 1000

multiply by 3 or 5

then divide by 40, round up

3 for no windows

5 for windows

Question 11

how much thickening agent do you use for fougasse

Answer 11

3 onces per gallon

Question 12

explain time fuse measurements with crimpers

Answer 12

accurate + or - 5 sec

base of leg to top of jaw = 25 sec

top of nut to top of jaw = 4 sec

the nut = 1 sec
