3. Recall all the syllabus objectives.
PGM1: GUIDED WEAPON PRINCIPLES
1.1 Main objective of guided weapon
1.1.1 Definition: A guided
missiles is a SPACE – TRAVERSING, UNMANNED VEHICLES which carries within itself
the Means for Controlling its flight path.
1.2 Why guide a missile?
1.2.1. These are the random movement at launch of any projectile.
1.2.2. The deflection in flight of the projectile as it travels towards the target.
PGM2: COMPARISON OF GUIDED WEAPON SYSTEM WITH A GUN
2.1 Advantage and Disadvantage
PGM3: CLASSIFICATION OF MISSILE SYSTEM
3.1 Two main group of missile guidance.
3.2 The guidance method use in missile system depended upon:
3.2.1 Missile role.
3.2.2 Launching site.
3.2.3 Target.
3.2.5 Accuracy
PGM4: COMMAND LINK
4.1 Main task of command link.
4.1.1 Is used to keep the missile on its proper flight path (trajectory)
4.1.2 Relay information to guidance system and control system. The guidance system can be thought as the brain of the missile.
PGM5: HOMING GUIDANCE
5.1 Main task- Control the flight path by using a device in the weapon.
5.1.1 Homing devices is designed to be sensitive on variety of energy forms i.e. RF, infrared, reflected laser, sound and visible light.
5.2 Type of homing guidance:
5.2.1 Active Homing.
5.2.2 Semiactive Homing.
5.2.3 Passive Homing.
5.2.4 Retransmission Homing or Track Via Missile (TVM).
5.2.1.1 Active Homing: The seeker contains both onboard the transmitter and receiver.
5.2.1.1.1 Search and acquisition are conducted by tracking sensor.
5.2.1.1.2 The transmitter sends out radar signals in the general direction of the target.
PGM6: THE CURVE PURSUIT TRAJECTORY
6.1 The mean of the curve pursuit trajectory
PGM7: PROPORTIONAL NAVIGATION
7.1 The basic principles:
PGM8: PRE-DETERMINED DATA SYSTEM
8.1The basic principles of trajectory.
8.2Type of trajectory and their difference.
PGM9: PRINCIPLES OF INERTIAL GUIDANCE
9.1The principles of inertial guidance and their block diagram representation.
PGM10 : THE BASIC ACCELEROMETERS
10.1How the acceleration works after launching the missile.
PGM 11: MISSILE PROPULSION UNIT
11.1The need for propulsion unit.
11.2The basic type of propulsion unit.
