Thermodynamic Analysis of Compressed Air Vehicle Propulsion



Introduction
The air flow of a compressed air car is schematically shown in Figure 1. The
following two questions need to be answered.
E-Motor Compressor
Schematic of air compression, compressed air transfer to car and
the use of compressed air for vehicle propulsion

Air Compression
Three compression processes are illustrated in a pressure-volume diagram
(Figures 2) and a temperature-entropy diagram (Fi ....etc

Advanced Propulsion Methods
abstract

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 ROCK ....etc

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 engines 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 the routi ....etc

PROPULSION SUBSYSTEMS
INTRODUCTION
Spacecraft are provided with sets of propulsive devices so they can maintain three-axis stability, control spin, execute maneuvers, and make minor adjustments in trajectory. The more powerful devices are usually called engines, and they may provide a force of several hundred newtons. These may be used to provide the large torques necessary to maintain stability during a solid rocket motor burn, or they may be the only rockets used for orbit insertion.
Smaller devices, generating betwee ....etc

ABSTRACT

A new concept for the interplanetary and interstellar mission engine. All current spacecraft use chemical rocket for launch and this fusion propulsion system uses fusion rockets for launch. Fusion propulsion has the potential to produce high speed transportation any where in the universe. In this propulsion use fusion reactions to produce thrust to propel rockets. In order to occur fusion we have to create conditions like high temperature about 100 million degree celcius and high pressure. At these conditions plasma is for ....etc

Laser Propulsion


To understand this technique of propulsion let us first see what are lasers and their properties, which enable them to be used to propel crafts.
Laser is an acronym for light amplification by simulated emission of radiation. It is an intense ray consisting of photons.
Properties of laser

Excitation of an atom
Laser light is monochromatic, directional and coherent
Monochromatic - means of one wavelength. In contrast, ordinary white light is a combination of different wavelengths. ....etc
