IDENTIFICATION OF UNDER WATER VEHICLE HYDRODYNAMIC EFFICIENTS USING FREE DECAY TESTS



INTRODUCTION
In recent years there has been an ever increasing number
of applications for unmanned underwater vehicles
(UUV) in various tasks, for instance in surveying and
exploration, or in missions such as the positioning
of underwater laboratories (Aguiar 1997). Improvements
in the evaluation of the hydrodynamic models
of UUV’s result in more effective control s ....etc

Magneto-optical current transformer technology (MOCT)

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed car ....etc

ABSTRACT


A good dynamics model is essential and critical for the successful design
of navigation and control system of an underwater vehicle. However, it is
difficult to determine the hydro2dynamics forces, especially the added m ....etc

The recent increase in the use of hard, high strength and temperature resistant materials in engineering necessitated the development of newer machining techniques. Conventional machining or finishing methods are not readily applicable to the new materials like hastalloy, nitralloy, waspalloy, nimonics, carbides, ceramics etc.


Conventional machining processes when applied to these newer materials:
1. Are uneconomical,
2. Produce poor degree of surface finish and accuracy,
3. Produce some stress,
4. Highly insufficient.

Newer machin ....etc

An accurate electric current transducer is a key component of any power system instrumentation. To measure currents power stations and substations conventionally employ inductive type current transformers with core and windings. For high voltage applications, porcelain insulators and oil-impregnated materials have to be used to produce insulation between the primary bus and the secondary windings. The insulation structure has to be designed carefully to avoid electric field stresses, which could eventually cause insulation breakdo ....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
