TURBOFAN ENGINES

INTRODUCTION

Jet Propulsion is the thrust imparting forward motion to an object, as a reaction to the rearward expulsion of a high-velocity liquid or gaseous stream.
A simple example of jet propulsion is the motion of an inflated balloon when the air is suddenly discharged. While the opening is held closed, the air pressure within the balloon is equal in all directions; when the stem is released, the internal pressure is less at the open end than at the opposite end, causing the balloo ....etc

SYNOPSIS
Helicopter is one of the earliest ideas for achieving flight. The advances in helicopter technology made it an extreme flying machine. In this seminar I discuss the historical backgrounds and early concepts of helicopter, then introducing the aerodynamic theory and principle behind helicopters, discussing the most potent mechanisms that are used in it. Also different configurations of helicopters have been described. Then discussing the first analytical theory to consider for a helicopter in for ....etc

Active Suspension System

COMPONENTS



A Computer or an electronic control unit (ECU)

Sensors

Actuator or Servo

Adjustable shocks and springs


Functions of Active Suspension

Improves driver control, safety and stability, with or without a load .
Eliminates sway and reduces roll on corners
Reduces axle wrap
Maximum safety
Absorbs load, rather than resisting it, thereby ensuring a much more comfortable ride
Eliminates the need for fitting extra blades which harden the ride
Better handling a ....etc

NOVEMBER 2010




ABSTRACT

A scramjet (supersonic combustion ramjet) is reminiscent of a ramjet. The basic components of scramjet are inlet, diffuser, fuel injector, flame holder, igniter, and combustion chamber and exhaust nozzle. The basic principle of scramjet is same as that of any type of engine, intake, compression, combustion ....etc

INTRODUCTION

The history of antimatter begins with a young physicist named Paul A.M.Dirac (1902-1984) and the strange implications of a mathematical equation. This British physicist formulated a theory for the motion of the electrons in electric and magnetic fields. Such theories had been formulated before, but what was unique about Dirac’s was that his included the effects of Einstein’s Special Theory of Relativity. This theory was formulated by him in 1928.Mean while he wrote down an equation, which combined quantum theory and s ....etc

Vertical Take “ off and Landing
INTRODUCTION
Twenty years after ever jet flight took place, vertical takeoff and landing (VTOL) emerged as a concept, which was soon to be successfully implemented. Dr A.A Griffith, in 1941 who was then the chief engineer of Rolls Royce ltd. put forward this idea in his paper to the aeronautical research council. He proposed the idea of using small lift engines for lift only and not for normal flight. He claimed that there was great advantage in using a wing configuration and prop ....etc

SOLAR THERMAL PROPULSION
ABSTRACT
Solar thermal propulsion is a form of space craft propulsion. Space craft propulsion is used to change the velocity of space craft and artificial satellites. There are many methods for space craft propulsion. Each method has draw backs and advantages, and space craft propulsion is an active area of research. Solar thermal propulsion conceived in 1956 by Kraft Echrike. Solar thermal propulsion is an excellent choice because it requires only one propellant gas and c ....etc

Design and manufacture of “White Metal Thrust Bearing”



Abstract of the project :
White metal bearings transmit the thrust exerted by shafts rotating at high speeds to the foundation of the machine. White metal thrust bearings were invented by Anthony Michell in 1905. Here, pads are used instead of rollers or balls and the bearing housing is flooded with a hydrodynamic fluid under pressures of about 100 bar in order to minimize ....etc

1. INTRODUCTION
Rocket engines that work much like an automobile engine are being developed at NASAâ„¢s Marshall Space Flight Center in Huntsville, Ala. Pulse detonation rocket engines offer a lightweight, low-cost alternative for space transportation. Pulse detonation rocket engine technology is being developed for upper stages that boost satellites to higher orbits. The advanced propulsion technology could also be used for lunar and planetary Landers and excursion vehicles that require throttle ....etc

DESIGN, IMPROVEMENT AND THRUST BEARING ANALYSIS OF OIL EXPELLER MACHINE


Introduction to Processing of mustard-rapeseed
Oilseed processing

Various small-scale techniques are available to process oilseeds locally. Careful
consideration is needed to select the system that will best suit the local
circumstances. These circumstances include the scale of operation required, the
availability of a power source, and a number of other factors.

Raw material preparation

Oilseeds and nuts should be properly dried before ....etc

CHEMICAL ROCKET ENGINES
1. INTRODUCTION
Chemical rocket engines, like those on the space shuttle, work by burning two gases to create heat, which causes the gases to expand and exit the engine through a nozzle. In so doing they create the thrust that lifts the shuttle into orbit. Smaller chemical engines are used to change orbits or to keep satellites in a particular orbit. For getting to very distant parts of the solar system chemical engines have the drawback in that it takes an enormous amount of fuel to deliver the p ....etc
