An overview of guided missiles

[attachment=18274]

Justification

an overview of guided missiles” is a general representation of information collected from the internet and other sources. This paper presentation provides a brief introduction of guided missiles. It does not provide some basic mathematical representation and concepts because it deals with some higher level physics and mathematics and some highly confidential issues associated with it.
The reason behind this topic is that it is an interesting field where application of mechanical engineering is widely dominated. This is one of the latest and vital technology which could decide the future of next generation wars. This technology is the symbol of power and I support it because it will strengthen our nation’s power and this could give us an opportunity to be counted among the developed countries instead of being counted in Developing countries.



What is a missile?
A rocket carrying a warhead of conventional or nuclear explosives; may be ballistic or directed by remote control projectile.
contain a computer and other special equipment that guides them
missiles can even chase and destroy a moving targets miles away without being detected by the advanced radar systems
Other guided missiles fly under human control, though they carry no pilot
A jet engine, rather than a rocket motor, powers a few kinds of missiles
Guided missiles form an important part of a nation and defence army



Difference between Missile & Rocket


A missile is any weapon which flies toward its target

could be anything from a rock that you pick up off the ground and throw at an enemy, to a spear, an arrow, a bullet, up to a multi-staged rocket carrying multiple MIRV-type nuclear weapons.

Where as, a rocket is simply a non-air-breathing object which is propelled by shooting a stream of gases out behind it.



General Principles of Missile Defence


detecting the missile (or warhead)
discriminating it from anything else
fire control, that is, finding precisely where to shoot
finally aiming and killing it by hitting it either with some sort of interceptor or with a form of laser energy
