piston engines or gas turbines. Turbine-powered Turboprop A turboprop engine is a type of turbine engine which drives an aircraft propeller using a reduction gear. The gas turbine is designed specifically for this application‚ with almost all of its output being used to drive the propeller. The engine’sexhaust gases do not contain enough energy‚ compared to a jet engine‚ to create significant thrust in the propulsion of the aircraft.The propeller is coupled to the turbine through a reduction gear that

Pumping Systems: Parallel and Series Configurations For some piping system designs‚ it may be desirable to consider a multiple pump system to meet the design requirements. Two typical options include parallel and series configurations of pumps. Specific performance criteria must be met when considering these options. Given a piping system which has a known design flow rate and head requirements‚ Qdes‚ hdes‚ the following pump selection criteria apply. Pumps in Parallel: Assuming that the pumps are

a memo to the board of directors as follows The diversity of our products requires that we reorganize along our major product lines. Toward this end I have established three new divisions commercial jet engines‚ military jet engines‚ and utility turbines. Each division will be headed by a new vice president who will report directly to me. I believe that this new approach will enhance our performance through the commitment of individual managers. It should also help us identify unprofitable areas

to the cabin pressurization system pre-cooler‚ for a typical passenger aircraft that’s powered by gas turbine engines‚ include in your answer where the air supply is taken off the engine The cabin pressurization system is designed to keep the pressurization of the inside of the aircraft to a higher level than outside the aircraft‚ this is done by taking air from the ram stage of the gas turbine. This air is then supplied to the heat exchanger at minimum pressure. When the aircraft is in flight‚

to Aircraft 1 School of Aerospace‚ Mechanical and Manufacturing Engineering Lecture 5A: Introduction to Aircraft Propulsion II Introduction History of Gas Turbines Since we are talking about turbines‚ there is an intimate relationship with turbo-machinery‚ hence the first important aspect to the history of gas turbines in the invention of the modern centrifugal pump by Appold in 1851. Then in 1902 Renault patented the centrifugal supercharger. This marks the application of turbo-machinery

STEAM TURBINES A steam turbine is a prime mover which converts heat energy into mechanical energy. In a conventional steam turbines cycle‚ water is used as the working fluid. The water is heated in a boiler by burning fuel. It evaporates into steam which is expanded in a turbine where mechanical power is generated. The steam generated is of high temperature and high pressure. The temperature is often in the 450 to 540 degrees centigrade range. The pressure ranges between 60 and 120 bar. The

Green Energy-My Points of view I have made my decision and I am for the development of the wind farm by each group. I am for the development for the following reasons. The first one is that wind is free and avalible for every one to use. Wind frams do not cause give any green house gases it is good for the enviroment and if Britian had lots of wind farms we wouldn’t have to use fossil fuels. Also if we use less fossil fuels that means that all the digging and mining for coal‚ oil and gas can be

as a centrifugal blower driven by exhaust gas turbines and used to supercharge an engine. (Merriam-Webster Dictionary) Turbochargers compress the air flow into the engine. One of the advantages of the air being compressed is that more air is being squeezed into the cylinder‚ more air in the cylinder means that more fuel can be added. It achieves the boost by using the exhaust flow from the exhaust to spin a turbine‚ which spins an air pump. The turbine spins at speeds up to 150‚000 RPM‚ that’s about
