[attachment=15998]
INTRODUCTION
Guided Missiles, usually containing conventional or nuclear explosives, guided in flight towards a target either by remote control or by internal mechanisms. Guided missiles vary widely in size and type, ranging from large strategic ballistic missiles with nuclear warheads to small, portable rockets carried by foot soldiers.
POWER SOURCE
1) SELF CONTAINED ROCKET MOTORS: It contains a motor fan which force it by the air to proceed. It is less efficient & used in the past era.
2) AIR BREATHING JET ENGINE’S: In this type of power source the combustion chamber in which the fuel burns is called the motor When the fuel in a solid-propellant rocket is ignited, the gases formed during combustion are forced out the nozzle and the rocket moves forward. The fuel is called the grain and is often formed with a hollow core for longer burning times.
Types of warhead
. Explosive: An explosive charge is used to disintegrate the target, and damage surrounding areas with a shockwave.
. Chemical: A toxic chemical, such as nerve gas is dispersed, which is designed to injure or kill human beings.
.Biological: An infectious agent, such as anthrax is dispersed, which is designed to sicken and kill humans
