INTRODUCTION
Spacecraft propulsion is used to change the velocity of spacecraft and artificial satellites. There are many different methods. Each method has drawbacks and advantages, and spacecraft propulsion is an active area of research. Most spacecraft today are propelled by heating the reaction mass and allowing it to flow out the back of the vehicle.For propulsion the required product is the velocity of the exhaust products of the reaction. All current spacecraft use chemical rocket for launch.

Propulsion subsystems in a spacecraft aid in preserving the three-axis stability and the control spin. In addition to it, they also help in carrying out manoeuvres and to bring about slight alterations in trajectory. The superior ones called Ëœenginesâ„¢ can infact, generate an acceleration of large torques in volume to sustain the stability of a solid rocket motor during burning phase. The delta-V for simple tasks like the interplanetary trajectory correction manoeuvres, orbit trim manoeuvres, reaction wheel de-saturation manoeuvres and ....etc

ABSTRACT

The Magneto Hydro Dynamic (MHD) propulsion thruster is designed to use magneto hydrodynamic force generated by sending electric current through a magnetic field created in sea water by superconducting magnets. The principle of MHD propulsion is to apply the Fleming's left hand rule of electromagnetics to sea water directly .In this propulsion system magnetic field is created in sea water by magnets fixed on a hul1. When electric current is sent to sea water at right angles to the magnetic field, and electromagnetic force (Lorentz f ....etc

Space travel has become a routine in the present world. Space is even a permanent settlement to some astronauts onboard the international Space Station. However, when you think of the size of our solar system, not to mention the universe, we have just taken baby steps into space. Conventional rocket propulsion is based on chemical propulsion systems. Now different methods have been evolved. This seminar will give an overview of some of the advanced propulsion methods like SOLAR THERMAL ROCKET PROPULSION, ELECTROSTATIC ION PROPULSION DRIVES, HAL ....etc

AIR BREATHING PROPULSION
In contrast to a rocket engine which, in addition to the fuel, carries along an oxidizer, an air-breathing propulsion system uses atmospheric air to oxidize the liquid fuel. Air- breathing propulsion systems include the jet engine, the ramjet and the scramjet. The field of air-breathing propulsion involves various disciplines in science and engineering such as fluid dynamics, turbo machinery aerodynamics, thermodynamics, and materials and structures.

ABSTRACT
An automotive propulsion concept is presented which
utilizes liquid nitrogen as the working fluid for an open
Rankine cycle. Ambient heat exchangers are used to power
an engine that is configured to maximize heat transfer during
the expansion stroke. If sufficient heat input during the
expansion process can be realized then this cryogenic
propulsive system would provide greater automotive ranges
and lower operating costs than those of electric vehicles
currently being considered for mass production.
The
feasibility of meeti ....etc
