SYNOPSIS
Autonomous underwater gliders, and in particular autonomous underwater gliders, represent a rapidly maturing technology with a large cost-saving potential over current ocean sampling technologies for sustained(month at a time) real-time measurements.
This report gives us an overview of the main building blocks of an underwater glider system for propulsion, control, communication and sensing. A typical glider operation, consisting of deployment, planning, monitoring and recovery will be descri ....etc

Traditional centrifugal compressors use roller bearings and hydrodynamic bearings, both of which consume power and require oil and lubrication system. This can be overcome by the introduction of new compressor technology called frictionless compressor technology. The frictionless compressor technology is compressor with the application of magnetic bearings and permanent magnet synchronous motor. In frictionless compressor instead of roller bearings and hydrodynamic bearings, magnetic bearings are used. Magnetic bearings consume less power and t ....etc

ABSTRACT

Electromagnetic bombs are Weapons of Electrical Mass Destruction with applications across a broad spectrum of targets, spanning both the strategic and tactical. As such their use offers a very high payoff in attacking the fundamental information processing and communication facilities of a target system. The massed application of these weapons will produce substantial paralysis in any target system, thus providing a decisive advantage in the conduct of Electronic Combat, Offensive Counter Air and Strategic Air Att ....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
 The magnetohydrodynamic propulsion is a new propulsion system which is used for propelling ships & submarines.
 The magnetohydrodynamic, or MHD, propulsion has no moving parts like propeller, gear, shafts etc
 Submarines fitted with it , cannot be detected easily
(as it is silent)
History
 First proposed by W A Rice in 60’s in USA
 He does experimental work on it using dc direct drive propulsion using battery driven magnets
 Speed 1.5 ....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

Cummins Crankshaft and Bearing Analysis Process

1. INTRODUCTION
This paper outlines the steps taken for the preliminary crankshaft and bearing design
analysis at Cummins. Major crankshaft dimensions must be chosen early in the engine design
process because they affect overall engine dimensions. Proper selection of the crank dimensions
requires multiple design iterations to avoid design alterations during the development stage when
any change is very costly. Therefore, the crankshaft and bearing analysis sho ....etc

INTRODUCTION

The next Pearl Harbor will not announce itself with a searing flash of nuclear light or with the plaintive wails of those dying of Ebola or its genetically engineered twin. You will hear a sharp crack in the distance. By the time you mistakenly identify this sound as an innocent clap of thunder, the civilized world will have become unhinged. Fluorescent lights and television sets will glow eerily bright, despite being turned off. The aroma of ozone mixed with smoldering plastic will seep from outlet covers as electric wires arc ....etc
