An aircraft engine is the component of the propulsion system for an aircraft that generates mechanical power. Aircraft engines are almost always either lightweight piston engines or gas turbines. The Combat aircrafts play a pivotal role in the defense of air worthiness of any nation. These have mostly turbo-jet engines which are generally air breathing type. This work presents the basic concepts of operation and various manufacturing processes...

Cryogenics, study and use of materials at very low temperatures. The upper limit of cryogenic temperatures has not been agreed on, but the American National Institute of Standards and Technology has suggested that the term cryogenics be applied to all temperatures below -150° C. Cryogenic temperatures are achieved either by the rapid evaporation of volatile liquids or by the expansion of gases confined initially at pressures of 150 to 200 atmo...

Engines and pumps are common engineering devices which have become essential to the smooth running of modern society. Many of these are very sophisticated and require infrastructure and high levels of technological competence to ensure their correct operation, for example, some are computer controlled, others require stable three phase electrical supplies, or clean hydrocarbon fuels. This project focuses on the identification, design, construc...

Turbochargers are commonly being used on diesel engines for many years. In contrast only a few petrol engines have been turbocharged until recently and it is unlikely that a large fraction of the world petrol engine will be so equipped. Most of the vehicles in the Indian automobile market continue to utilize turbocharged diesel engines compared to gasoline engines. However, experts are of the opinion that turbo growth, in the future would not ...
