SCRAMJET ENGINE



SCRAMJET

A scramjet (supersonic combustion ramjet) is a variation of a ramjet with the key difference being that the flow in the combustor is supersonic.

The first successful launch (Hyshot II) was of a University of Queensland scramjet on 30 July 2002.

NASA first flew thrust producing scramjet powered vehicle in 2004 with the X-43A. It set a new speed record of 12,144 km/h (7,546 mph), or Mach 9.8, on November 16, 2004.

3 Point Starter Working Principle and Construction of Three Point Starter

A 3 point starter in simple words is a device that helps in the starting and running of a shunt wound DC motor or compound wound DC motor. Now the question is why these types of DC motors require the assistance of the starter in the first case. The only explanation to that is given by the presence of back emf Eb, which plays a critical role in governing the operation of the motor. The back emf, develops as the motor armature starts to rotate in presence of the magneti ....etc

Abstract

Automatic Night Lamp with Morning Alarm System is a simple yet powerful concept, which uses transistor as a switch. By using this system manual works are 100% removed. It automatically switches ON lights when the sunlight goes below the visible region of our eyes. This is done by a sensor called Light Dependant Resistor (LDR) which senses the light actually like our eyes. It automatically switches OFF lights whenever the sunlight comes, visible to our eyes and activates the morning alarm.

By using this system energy consumption i ....etc

ME Engines the New Generation of Diesel Engines

INTRODUCTION

The introduction of the electronically controlled camshaft-less low speed diesel engines, which is now gaining momentum, is a milestone in diesel technology that deserves a place in history like Rudolf Diesel s first engine in Augsburg, the 1912 motor vessel Selandia, the introduction of turbocharging on two-stroke diesels in 1954, and the first SCR (Selective Catalytic NOx Reduction) systems on ships in 1989. This paper will outline how MAN B&W takes a ....etc

Introduction to westernization.
Westernization is a process in which societies adopt western cultures in areas such as industry, technology, law, politics, economies and lifestyles, clothing, language etc. Today, there are many people who are westernizing themselves among many cultures. Westernization has become common in the world especially in India. People normally get a plastic surgery to look western is because it gives the back a round and a perkier shape, it also straightens hair. People want to change themselves like this because they ....etc

ABSTRACT
In aerodynamics, hypersonic speeds are speeds that are highly supersonic. In the 1970s, the term generally came to refer to speeds of Mach 5 (5 times the speed of sound) and above. The hypersonic regime is a subset of the supersonic regime.
Supersonic airflow is decidedly different from subsonic flow. Nearly everything about the way an aircraft flies changes dramatically as an aircraft accelerates to supersonic speeds. Even with this strong demarcation, there is still some debate as to the definition of superso ....etc

ABSRACT
HCCI has characteristics of the two most popular forms of combustion used in IC engines: homogeneous charge spark ignition (gasoline engines) and stratified charge compression ignition (diesel engines). As in homogeneous charge spark ignition, the fuel and oxidizer are mixed together. However, rather than using an electric discharge to ignite a portion of the mixture, the concentration and temperature of the mixture are raised by compression until the entire mixture reacts spontaneously. Stratified charge compres ....etc

Today science and technology are making advances at an amazing rate. So vast is its impact that people now fear the unthinkable. Technology can more appropriately be termed as a friend of humanity. Inventions are the best ways to serve the mankind. Today we are submerged in the sea of discoveries and inventions. The advantages, the society has received from these science inventions and discoveries are immeasurable. From telephones to the internet, calculators to computers, cars to rockets, we are mere ....etc
