FUNDAMENTALS OF GAS TURBINE ENGINES INTRODUCTION The gas turbine is an internal combustion engine that uses air as the working fluid. The engine extracts chemical energy from fuel and converts it to mechanical energy using the gaseous energy of the working fluid (air) to drive the engine and propeller, which, in turn, propel the airplane. THE GAS TURBINE CYCLE The basic principle of the airplane turbine engine is identical to any and all engines that extract energy from chemical fuel. The basic

Hudson’s Bay Company and IBM: Virtual Blade Platform Case Study Three types of sever virtualization Visualization uses special software called “hypervisor” which creates a layer and abstracts and interacts with the physical resources and reallocates them more efficiently. It serves as a platform for the virtual servers’ operating systems. The hypervisor keeps each virtual server independent and unaware of the other running servers. It monitors the physical server’s resources and
