Overview

Question 1

“Shorter-ragned weapons designed for use in the immediate combat area”

Answer 1

Tactical Guided Missile

Question 2

Cruise Missile

Answer 2

“Range up to 2500 km, powered by air-breating engines” that provide almost continuous propulsion along a low, level flight path.

Question 3

Ballistic Missile

Answer 3

Global range, rocket propelled for the first part of the flight then follows ballistic trajectory.

Question 4

Describe the different speeds of missiles:
Subsonic
Supersonic
Hypersonic

Answer 4

Subsonic: < 1 Ma
Supersonic: 2-3 Ma
Hypersonic: > 5 Ma

Question 5

Give ranges for IRBMs and ICBMs

Answer 5

IRBMs: 2750 - 5000 km
ICBMs: > 5000 km

Question 6

Define:

Offensive missiles
Defensive Missiles

Answer 6

Offensive Missiles: strike the enemy
Defensive Missiles: protect own units

Question 7

Describe the Launch Sequence

Answer 7

1. Handshake
2. Target data upload
3. Engine test (Point of no return)
4. Launch

Question 8

What are the phases of the missile flight path?

Answer 8

Boost: Brought up to flight speed and stable flight path.
Midcourse: Guides missile near the target. Not all missiles have a midcourse phase.
Terminal: Actively closes onto target.

Question 9

Define: Relative wind

Answer 9

The ariflow a missile experiences as it moves through the air

Question 10

Define: Angle of Attack

Answer 10

The angle between the oncoming air or the relative wind and the chord.

Question 11

Define: Induced Drag

Answer 11

Wingtip vortices result in downwash which reduces the effective angle of attack, increasing theoverall drag.

Question 12

Define: Parasitic Drag

Answer 12

Includes Form Drag and Friction Drag

Question 13

Define: Center of pressure:

Answer 13

Lift and drag act through the centre of pressure.

Moves as the AoA moves.

Question 14

“The ability of the missile to maintain equilibrium and return to its original flight path after a disturbance”

Answer 14

Stability

Question 15

How does the CG of the missile in relation to the CP affect stability?

Answer 15

When the CG is in front of the CP, then as the missile rotates down, the AoA will decrease, decreasing lift, reducing the downward rotating moment.

Question 16

Define: Stall

Answer 16

A reduction in the lift coefficient generated by a surface as the angle of the attack increases.

When the critical angle of attack is exceeded and there is flow separation, breaking continuity in the flow circulation.

Question 17

“the purpose is to place a weapon into a lfight path as rapidly as the situtation demands.”

Answer 17

Launching System

Question 18

What are requirements of launching systems?

Answer 18

Speed
Reliability
Safety
Compatibility

Question 19

What are 3 types of launchers?

Answer 19

Rail
Canister
Platform

Question 20

Answer 20

Rail Launcher

Question 21

Answer 21

Canister Launcher (invludes VLS)

Question 22

Answer 22

Platform Launcher

Question 23

Define: Telemetry

Answer 23

The process of collecting missile flight data in an automated communications sytem in order to improve performance and provide safety and control.
