Ballistics

Question 1

If several projectiles are fired from the same weapon with the same elevation and deflection settings, the individual points of impact will be scattered about the endpoint. The degree of scatter of these rounds is called ________

Answer 1

Dispersion

Question 2

The altitude from which the projectile is fired and ranged to target determines ________ and _______

Answer 2

Impact pattern

Fragmentation pattern

Question 3

Fragmentation pattern length _________ with high angle impact

Answer 3

Decreases

Question 4

What are interior ballistics

Answer 4

Barrel wear, propellant charges, projectile weight, launcher tube and rocket pod alignment, thrust misalignment

Question 5

What are exterior ballistics

Answer 5

Air resistance
Gravity
Yaw
Projectile drift 
Wind drift

Question 6

What are Ariel ballistics

Answer 6

Rotor down wash
Angular rate
turning bank
propellant force 
center of gravity 
relative window effect 
trajectory shift 
port starboard effect 
projectile jump

Question 7

What are terminal ballistics

Answer 7

Blast heat and fragmentation influenced by fuse and warhead function impact angle and surface condition

Question 8

Define maximum effective range

Answer 8

Distance at which there is a 50% chance of hitting and destroying the target

Question 9

What is the cause of the greatest air for free flight rockets

Answer 9

Thrust misalignment

Question 10

Which exterior ballistic is not compensated for by the MP

Answer 10

Yaw

Question 11

What exterior ballistic causes a clockwise spin in projectile to move to the right

Answer 11

Projectile drift

Question 12

Why is the aerial rock it’s just a more accurate one fired from an OGE hover rather than an IGE hover

Answer 12

IGE hover Cannot apply down wash compensation due to random induced flow

Question 13

What is angular rate error and how do you prevent or minimize it

Answer 13

Error caused by the motion in the launch platform as the projectile leaves the weapon

Question 14

What are the aerial ballistic characteristics affecting thin stabilization projectiles

Answer 14

Propellant force
CG
Relative wind

Question 15

What causes a rocket to seek into a crosswind or impact past the target when fired during an accelerating climb

Answer 15

Relative wind affect

Question 16

What is projectile jump and when does it occur when firing from a hover

Answer 16

When a weapon is fired into induced crosswind

Question 17

Is projectile jump compensated by the MP

Answer 17

No

Question 18

What determines the amount of lead required when firing off access to the right or left

Answer 18

Aircraft airspeed
angle of deflection
projectile velocity
target range

Question 19

What is it called when projectile drift and trajectory shit combine with each other

Answer 19

Port starboard affect

Question 20

What are three factors that affect dispersion discussed in conjunction with terminal ballistics

Answer 20

Vibration
Sights
Boresight

Question 21

_______ an additional type of fragmentation is produced by target structure itself

Answer 21

Spall

Question 22

At approximately ___ kts indicated forward airspeed, the influence vector is moved just asked of the rocket launcher forward bulkhead, thus reducing down wash to ____

Answer 22

33

Zero

Question 23

With the _____ as the selected site, lead angle compensation is not computed or added to the Gun turret or rocket pylon position command nor is the target state estimator employed

Answer 23

IHADSS
