Kinetic Energy Attack On Armour Flashcards
Kinetic energy attack can be described as,
Hitting the target armour with a projectile of sufficiently high velocity to achieve penetration.
The aim is to direct as much energy as possible onto a small area of the target, optimising penetration.
For ballistics requirements, does mass or velocity have greater influence?
Velocity has greater influence than mass
Internal ballistic requirements
To achieve the highest possible muzzles velocity, a projectile should
a wide base for the proellant to work against and
low mass to over come
External ballistic requirements?
“Prevent deceleration due to air resistance”
Small cross sectional area
High mass
High velocity
Aerodynamic design
Penetration at target depends on the behaviour of materials of the armour and the projectiles KE needing?
Small cross sectional area
High mass
high velocity
Hard material
Two forms or stabilisation? And their ratio of lenght:diameter
Spin 7:1
Fin 15:1
What were early AP shells made of?
Full calibre solid steel projectiles
3 types of shot failure?
Barrelling
Shattering
Lateral bending
Purpose of a cap?
Initial indentation
Prevent shot failure
Rotate shot to normal
What are two types of discarding sabot?
Petal
Pot

Armour piercing discarding sabot - trace
What does APCNR stand for?
Armour piercing composite non rigid
