Q

What is V of D?

A

The rate, in metres per second, at which the wave of detonation passes through an explosive substance. V of D’s lie in the approx range of 1500 - 9000 m/s

Q

Stand-off distances

A

2 CD - little degradation

5 CD - peak performance

17
Q

What are types of shaped charge liner material?

A

Copper - most common
Steel - reduced penetration, corrosion
Aluminium - reduced penetration, increased thermal effects

18
Q

how can we achieve spin compensation?

A

Slipping driving bands
fluted liners
spin compensated liners

19
Q

Plate charges

A

Miznay-schardin effect
EFP
SFF

20
Q

What are the 6 types of targets?

A 
People
Equipment
Structures
Aircraft
Vehicle
Complex
21
Q

What are the types of explosion?

A

Physical
Chemical
Nuclear

22
Q

What is kinetic energy?

A

A shot which dissipates its energy on impact and requires no triggering device

23
Q

What is reverse impact detonation?

A

Detonation occurs befor the fuze can detonate the fill. The shock wave will travel in the wrong direction

24
Q

Define a physical explosion

A

Sudden expansion of gases into a volume much greater than the original one accompanied by noise and violent movement

25
Q

7 targets of FAE

A 
Structures
Concentration of armoir
Parked aircraft
Mine filed clearance
Ships
Bunkers/ trenches
Concentration of troops in open
26
Q

Reduction of aircraft vulnerable areas

A 
Burying sensitive components
Armouring
Self sealing fuel tanks
Separating components
Concentrating sensitive components
27
Q

Most efficient mode of attack against personnel

A

High probability of hit
Rapid transfer of energy
No unnecessary overkill

28
Q

What factors affect frag performance?

A

Orientation
Distribution
Height of burst

29
Q

What is blast?

A

A violent disruptive effect caused by an explosion. There is an evolution of heat and gas which produces a shock wave from the center.

30
Q

What are the 3 phases of blast?

A

Shock front
Positive phase
Negative phase

31
Q

What are the factors affecting energy transfer?

A

Fragment mass and velocity

Fragment cross sectional area stability of the fragment

32
Q

What is deflagration?

A

Subsonic combustion that propagates through thermal conductivity

33
Q

What is quasi static pressure

A

Em explosion inside a structure
