Brayton cycle depicts the air standard model of a gas turbine power cycle and is used in all applications involving turbine engines; such as jet engines. A simple gas turbine is comprised of three main components: a compressor‚ combustor and a turbine. Air is compressed in the compressor‚ then mixed with fuel and burned under constant pressure conditions in the combustor. The hot gases created from this process are allowed to expand through the turbine to perform work. Low pressure air is drawn into

The Pelton wheel is a water impulse turbine. It was invented by Lester Allan Pelton in the 1870s. The Pelton wheel extracts energy from the impulse of moving water‚ as opposed to its weight like traditional overshot water wheel. Although many variations of impulse turbines existed prior to Pelton ’s design‚ they were less efficient than Pelton ’s design; the water leaving these wheels typically still had high speed‚ and carried away much of the energy. Pelton ’s paddle geometry was designed so that

There is perhaps not a better symbol for human ingenuity and technological advancement than the jet airplane. Since the early 19th century‚ beginning with Otto Lilienthal‚ to the Wright Brothers’ first airplane‚ humans have continuously strived to understand and improve upon the concepts of flight. Today‚ we have mastered the concepts of flight‚ as exemplified by the jet airplane‚ which is now the standard for modern air travel. To truly appreciate just how far we’ve come‚ it is important for one

They are also used in internal combustion engines as superchargers and turbochargers.

A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails.[1][2] Originally‚ windmills were developed for milling grain for food production. In the course of history‚ the windmill machinery was adapted to many other industrial uses.[3] An important non-milling use is to pump water‚ either for land drainage or to extract groundwater.

are going to describe three of the four levels of planning and how three different companies (MCI World Com‚ Empire‚ and GE) use them to their advantage. First we will look at how GE uses tactical planning in the employment of producing parts for turbine engines. Then we will talk about how MCI ’s operational planning built a reputation that carried them through difficult times. Lastly‚ we will discover how Empire embraced a new product and used strategic planning to overcome some daunting obstacles
