Turbine Engine & Gas Turbine Engine
Sir Frank Wittle, a British aeronautical engineer and aviator, invented the turbojet engine. Gas turbine engines took off, and have been soaring ever since. They offer an unmatched power to weight ratio, which make them ideal for many applications. Turbine engines are used in aircraft and on boats. Some smaller gas turbine engines are even used to produce electrical power, drive pumps, and generate steam.
Finally the turbine drives controllable pitch propellers through a conventional main reduction gear, shaft and clutch. Gas turbine engines have some advantages over diesel engines. As said by Marshal Brain, they have a great power-to-weight ratio compared to other internal combustion engines. That is, the power you get out of the engine compared to the weight of the engine itself is excellent. Gas turbine engines are smaller than their internal combustion engine counterparts of the same power.
The vanes at the first stage reduce the speed of air and direct it to the compressor rotor blades of second stage with the process continuing through all the stages of compressor rotor. From here, air enters the section of diffusion (Mattingly, Heiser and Pratt). The altitude of the location of gas turbine alters the power developed by the gas turbine. The reason is the decreasing air density with altitude, hence on a dry or humid day; the gas turbine at high altitude will swallow air of less weight. With the increase in the forward speed, increases the ram air pressure along with pressure and air temperature. Ram air pressure is the air pressure of free stream created by the aircraft engine’s forward motion (Hill and Peterson).
To complete the construction of the engine, all of the displays for the thermocouples and pressure gauges should be mounted in a display panel so that students can view all of the relevant information in one location. The push buttonfor the igniter could also be mounted to this panel. Once all of these components have been integrated, the gas-turbine will be completed.
