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

NTRODUCTION:

The predominant type of prime movers for DP propulsion plant is Electric Drive.


The most commonly used motor drives are:


DC converters, or SCR for DC motors.

Cyclo converters for AC motors ,normally for Synchronous motors .

Current Source Inverters (CSI) for Ac motors (Synchronous Motors )

Voltage Source Inverters ,(VSI)for AC motors ,i.e. asynchronous, ....etc

REDUCED EMISSIONS OF OXIDES OF NITROGEN IN SHIP ENGINES

INTRODUCTION

Oxides of nitrogen emission from ship engines are significant on a global level. These emissions participate in the formation of photochemical smog and acid rain. Here we look at to some ways by which these emissions can be reduced.

Mechanism of NOx Formation in Diesel Engines.

At the temperature of the Burning of fuel spray (about 2000 K to 2500 K).
Nitrogen + Oxygen Oxides of Nitrogen

Introduction

This study is motivated by a real problem at the Alang ship-dismantling facility near Bhavnagar in Gujarat. The focus of this study is the paint chip waste which is generated in ship breaking activity. Alang, located 56 Km away from Bhavnagar city in Gujarat, came up as ship breaking site during 1982-83. Hundreds of old ships, after their useful life, are broken at the Alang ship breaking yards without any precaution to protect the environment. Ship breaking and its harmful consequ ....etc

The steering gear system has three main parts:

control equipment
power unit
transmission to the rudder stock.
In brief, the operation of the steering gear can be explained as - With the help of the control system, a signal of desired rudder angle is sent from the bridge. This signal activates the power unit with which the rudder is attached. The rudder moves with the help of the power unit till the right angle is reached. ....etc

INTRODUCTION

The growth of science and technology at an unprecedented pace in the past century was facilitated by the surplus fuel reserves that sustained the developmental requirements in a post industrial revolution era. The oil shock of 1973 brought into existence a sudden setback to this economic growth rate in industrialised nations. The vulnerability of the present developments to be negated by a fuel crisis has shifted the focus of research from better designs during the pa ....etc

This paper discusses new techniques which aim to overcome the shortcomings of the protective system. These techniques are composed of advanced monitoring and control, automated failure location, automated intelligent system reconfiguration and restoration, and self-optimizing under partial failure.


The first electrical power system was installed on the USS Trenton in 1883 (Ykema 1988). The system consisted of a single dynamo supplying current to 247 lamps at a voltage of 10 volts d.c. Until the 1914 to 1917 period, the early electrical pow ....etc
