Turbine Engine Classification, Benefits and Application Research Paper

Turbine Engine Classification, Benefits and Application - Research Paper Example The axial-flow engine functions by compressing the air through a series of rotating and stationary air-foils which in turn move the air parallel to the longitudinal axis. The centrifugal axial flow design, on the other hand, uses both kinds of compressors in order to achieve the desired compression. This machine has four sections: turbine section, combustion chamber, compressor, and the exhaust. Inlet air passes through the compressor section at a high rate of speed to the combustion chamber. In the combustion chamber, there are fuel inlet and the igniter for combustion. The turbine is driven by the expanding air which is connected to the compressor by a shaft to sustain the engine operation. This kind of engines is limited in terms of range and endurance. A turboprop engine is a turbine engine machine that divides a propeller through a reduction gear. Power turbine connected by a shaft is driven by the exhaust gases, and this drives the reduction gear assembly. Optimum propeller performance which is achieved at low speeds is brought about by the reduction gear. These machines are most efficient at high speeds of between 250 and 400 m.p.h and also performed well at slow airspeeds. These machines are nowadays used in small airliners and transport aircraft which are sufficient for landing and required for takeoff. This turbofan engine machine combines the best features of the turbojet and the turboprop. Turbofan engines are designed to increase thrust by diverting the airflow around the combustion chamber. This only increase the thrust without increasing fuel consumption. This is because it increases the total mass of air passing through the engine reducing the velocity within the same energy supplied. Most airlines nowadays are powered by turbofan engines. This machine is widely used in helicopters. Its a form of gas-turbine engine. It drives the helicopter rotor though it does not have a propeller.
