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

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.

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

Titanium matrix composites (TMCs) have been extensively evaluated for their potential to replace conventional superalloys in high temperature structural applications, as they provide significant weight-savings while maintaining comparable mechanical properties. Gamma titanium aluminide alloys and an appropriate fiber could offer an improved TMC for use in intermediate temperature applications (400-800°C). The purpose of this investigation is aimed at evaluating the potential of a gamma titanium aluminide alloy with nominal co ....etc

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

ABSTRACT
Hypersonic sound technology from American Technology Corporation employs ultrasonic waves to create audible sound in the air. It works by using harmless ultrasonic tones that we can't hear. These tones use the property of air to create new tones that are within the range of human hearing. The result is audible sound. The acoustical sound wave is created directly in the air molecules by down-converting ultrasonic energy to the frequency spectrum we can hear. Hyper Sonic Sound is produced without the excess bag ....etc

Abstract
A numerical study has been carried out to investigate the full flow path and aerodynamic characteristics of a hypersonic vehicle ata 7.0 free stream Mach number. Results indicate that the inlet started and unstarted operations have remarkable effects on the flow patternof the full flow path. When the inlet operates in a started mode, the transverse pressure gradient generated by the forebody alters theair captured characteristics and the entering flow quality of the inlet. Furthermore, the expansion proces ....etc
