This document summarizes a seminar on missile technology presented by Suraj Kholia. It defines missiles as weapons that are thrown or guided to a target. It describes the major components of missiles as the warhead, guidance system, propulsion system, and fins. It distinguishes between unguided ballistic missiles that cannot be controlled after launching and guided cruise missiles, such as those that use GPS or satellite navigation. It also discusses the classification of missiles by mode (such as air-to-air or surface-to-surface), speed (subsonic, supersonic, hypersonic), examples of Indian ballistic missiles, and how cruise missiles function as small unmanned aircraft that can travel at supersonic

2. What is missile?
• Missile is a weapon or an object that is
thrown at a target.
• MAJOR COMPONENTS OF MISSILE
 WARHEAD
 GUIDANCE SYSTEM
 PROPULSION SYSTEM
 FINS

3. Types of missile
• There are two types of missiles:
• UNGUIDED OR BALLISTIC MISSILES
which moves freely to the target and
can’t be controlled after launching.
• GUIDED MISSILES which are guided
through remote controls e.g. Cruise
missile.

4. MISSILE CLASSIFICATION
• MODE
 Air to air
 Air to surface
 Surface to air
 Surface to surface
 Under sea to surface
• SPEED
 Subsonic
 Supersonic
 Hypersonic

5. WHAT IS BALLISTIC MISSILE?
• Ballistic missile is a missile that has
ballistic trajectory over most of its flight
path.
• Ballistic missiles can be launched from
ships and land based facilities.
• AGNI, DHANUSH, TRISHUL, PRITHVI are
some of the examples of indian ballistic
missiles.

6. WHAT IS CRUISE MISSILE?
• Cruise missile is basically a small
unmanned aircraft.
• They are also called as unmanned aerial
vehicles (UAV).
• Cruise missiles are designed to deliver a
large warhead over long distance with
high accuracy.
• Modern cruise missiles can travel at
supersonic or hypersonic speeds.

7. LAUNCHING OF CRUISE MISSILES

9. GUIDANCE SYSTEM
• Missile guidance refers to a variety of
methods of guiding a missile or a guided
bomb to its intended target.
TYPES OF GUIDANCE SYSTEM
GPS
SATELLITE NAVIGATION
TERRAIN CONTOUR MATCHING

10. PROPULSION SYSTEM
• Propulsion in missiles is achieved by jet engines.
• Jet engine is a reaction engine that discharges a fast
moving jet which generates thrust and propels the
missile.
• All the jet engines work on a TD cycle called brayton
cycle.
• Along with the brayton cycle, expansion of gases in
the nozzle is carried out in order to achieve the high
velocity of missiles.

11. WORKING OF MISSILE ENGINE
• Brayton cycle involves three process:
Air compression
Heat supplied in combustion chamber
Expansion of gases in turbine
• The use of turbine in the missile is to run the
compressor.
• The remaining pressure energy of the exhaust is
used to gain the high velocity for missiles by
expanding the exhaust in nozzle.

12. CONCLUSION
• Currently cruise missiles are among the
most expensive of single-use weapons,
up to several million dollars.
• If they are got in wrong hands, they will
cause lots of destruction of wide area,
money and men.
