INTRODUCTION



CAVITATION

Cavitation is the process of formation of vapour bubbles of flowing fluid in a region where the pressure of the liquid falls below its vapour pressure and the sudden collapsing of these vapour bubbles in region of high pressure. At first small vapour filled bubbles are formed that gradually increase in size. As the pressure of the surrounding liquid increases, the cavity suddenly collapses-a centimeter sized cavity collapses in milliseconds. Cavities implode violently and create shock waves that dig pits in exp ....etc

FLYING SIMPLE PLASTIC AIR CRAFT DESIGN
NATIONALWORKSHOP
Unmanned Aerial Vehicles (UAVs)
Unmanned Aerial Vehicles (UAVs) are remotely piloted or self-piloted aircraft that can carry cameras, sensors, communications equipment or other payloads. They have been used in a reconnaissance and intelligence-gathering role since the 1950s, and more challenging roles are envisioned, including combat missions. Since ....etc

Abstract:

The first production engine has been assembled and completed initial testing. The Company has had to design and build a custom dynamometer on which to complete engine testing. After testing has been completed on the first engine, it was installed in an aircraft like a Cessna 182 or a Piper Cherokee that will be able to demonstrate the engine's performance capability

The original engine is patented and the Company has now made patent applications and received patent pending status for additional features that have been refined. A ....etc

Steam Powered Robots
Abstract:
Steam may be the answer to a problem that has always dogged robotics: how to feed a robot enough energy to do useful work But steam doesnâ„¢t mean old fashioned boilers, water supply, and burning fuel. Instead this technique makes use of hydrogen peroxide to generate steam.
A major barrier holding back humanoid robots is the lack of decent motors. They also need a power supply that doesnâ„¢t take all of the robotâ„¢s energy just to move i ....etc

ABSTRACT





A torpedo is self propelled under water missiles with its own guidance system. They are also used as parts of other weapons. It is designed to detonate on contact or in proximity to a target. The torpedoes used against submarines are shorter and lighter .The main types of torpedoes used in U.S navy are MARK 46, MARK 48, and MARK 50.
In my topic, I would like to give a brief description on torpedoes, its working and its feat ....etc

ABSTRACT
The origin of the missile can be traced back to the roman war machine the catapult. The guided missile was born when Werner Von Siemens suggested a guide torpedo for submarines in the late 19th century. From these beginnings the present day trident and tomahawk are guided from the skies using the GPS signals. This seminar deals with the measurement concept that tests the missile accuracy. SATRACK receives, rebroadcast, records and tracks the satellite signals sent by the GPS signals. The reception and rebroadcast o ....etc

DEFINITION:
“IT IS A SMALL CREWLESS, UNDER SEA CRAFT, SELF PROPELLED AND SELF STEERED
IT IS EXPLOSIVE WHICH IS ARRANGED TO DETONATE IN CONTACT WITH OR IN THE PROPER PROXIMITY OF ITS TARGET.”
TORPEDO EVOLUTION IN THE PAST
FIRST TORPEDO MADE IN 1866.
FIRST THERMAL TORPEDO MADE IN 1900.
LATER ON GERMANS DEVELOPED ELECTRIC TORPEDO.
DEMAND FOR FASTER MOVING TORPEDOES GREW WITH INCREASE IN SHIP’S.
