Target analysis Flashcards
What are the 3 sub divisions of aircraft for targets?
Fast moving aircraft
Slow moving aircraft
Helicopters
What are the 7 types of warhead to attack aircraft?
Blast - external and intenral Fragmentation Fragmentation and blast Special kinetic energy - Discrete rod and continuous rod Shaped charges Sub-projectiles Cluster
What are the aircraft damage criteria?
KK-Kill - Immediate and catastrophic disintegration
K-kill -Target destroyed < 10 secs
A-kill - Target destroyed < 5 mins
B-kill - target defeated < 5 hrs
C-kill - targets mission not achieved
E-kill - target may complete mission but needs repair
What are the vulnerable areas of an aircraft?
Avionics Fuel tanks and lines crew flight controls air frame engines power transmission systems payload
Types of armour?
Rolled homogoneous armour
Spaced homogenous
Ply
Face hardened
What are the 3 damage assessments of tank armour
M - Mobility Kill
F - Fire power kill
K - Completely destroyed
What are the high energy forms of attack?
Kinetic energy
Chemical energy
Combination of both
Factors affecting shape charges
Cone diameter Shape of liner Liner material Stand off distance rate of spin
what are the types of Behind armour affects?
Luminescence
Spalling
Heat/fires
Overpressure
What is V of D?
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
What are the factors affecting v of d?
Density of the charge
Charge diameter
Degree of confinement
Strength of detonator
What is the definition of a shaped charge?
A charge shaped so as to concentrate its explosive force in a particular direction
How do shaped charges achieve their effect?
Through an intense concentration of kinetic energy
What affects the performance of shaped charges?
Liner material Shape of liner Cone diameter Stand-off distance Rate of spin
How do shaped charges achieve their affect?
By intense concentration of kinetic energy
Stand-off distances
2 CD - little degradation
5 CD - peak performance
What are types of shaped charge liner material?
Copper - most common
Steel - reduced penetration, corrosion
Aluminium - reduced penetration, increased thermal effects
how can we achieve spin compensation?
Slipping driving bands
fluted liners
spin compensated liners
Plate charges
Miznay-schardin effect
EFP
SFF
What are the 6 types of targets?
People Equipment Structures Aircraft Vehicle Complex
What are the types of explosion?
Physical
Chemical
Nuclear
What is kinetic energy?
A shot which dissipates its energy on impact and requires no triggering device
What is reverse impact detonation?
Detonation occurs befor the fuze can detonate the fill. The shock wave will travel in the wrong direction
Define a physical explosion
Sudden expansion of gases into a volume much greater than the original one accompanied by noise and violent movement
7 targets of FAE
Structures Concentration of armoir Parked aircraft Mine filed clearance Ships Bunkers/ trenches Concentration of troops in open
Reduction of aircraft vulnerable areas
Burying sensitive components Armouring Self sealing fuel tanks Separating components Concentrating sensitive components
Most efficient mode of attack against personnel
High probability of hit
Rapid transfer of energy
No unnecessary overkill
What factors affect frag performance?
Orientation
Distribution
Height of burst
What is blast?
A violent disruptive effect caused by an explosion. There is an evolution of heat and gas which produces a shock wave from the center.
What are the 3 phases of blast?
Shock front
Positive phase
Negative phase
What are the factors affecting energy transfer?
Fragment mass and velocity
Fragment cross sectional area stability of the fragment
What is deflagration?
Subsonic combustion that propagates through thermal conductivity
What is quasi static pressure
Em explosion inside a structure
