There are five types of predetermined guidance. One is Pre-set. Name the other four
Terrestrial reference
Radio Navigation
Celestial Navigation
inertial Navigation
SACLOS stand for
Semi Automatic Command to Line of Sight
Define ‘Missile Guidance’
Is the ability to alter the direction of the flight of a missile after launch and usually to be able to do this until it is close to the point of impact
Name the three types of homing guidance
Active
Semi Active
Passive
List the components of a guidance system
Tracking device
Computing device
Directing device
three phases of guidance
Launch phase (gathering phase)
Mid course phase
Terminal phase
One of the four requirements of an effective missile propulsion is to accelerate the missile from rest. List three others
a. Provide sustained thrust for the missile to attain maximum range
b. Provide a consistent level of thrust under all conditions
c. Does not interfere with the guidance or control systems of the missile
The Bi-propellant engine consists of four main assemblies
- Storage tanks for propellants
- Engine
- Propellant feed systems
- Fuel control system
One of the advantages of solid propellant fuel systems is that it ‘Can be a stress bearing member’. List 3 more
- Ease of handling and storage
- Non Toxic
- Simple Design
