Layout and Operation of a Jet Engine.

I will pay for the following article Layout and Operation of a Jet Engine. The work is to be 9 pages with three to five sources, with in-text citations and a reference page. Turbine gas engines have almost replaced the piston engines in the aviation industry for aircraft power generation. Categorized as turbojet, turbofan, turboprop, or turboshaft engine, the gas turbine engines are the most significant breakthrough in the history of aviation.

Constant (1980) highlights that specific to their purpose, different types of engines are employed in the industry. Design characteristics including a number of spools, the principle of compression, distribution of airflow within the engine, utilization of the exhaust gas are the main deciding factors for this purpose. Basically, four types of turbine engines are used in the aviation industry, these include

In Turbojet and turbofan engines, the reaction of exhaust gases leaving the exhaust nozzle is used to produce thrust. Turbofan engines are further classified as high-bypass or low-bypass-ratio engines based on requirements of mass flow. A typical schematic diagram of turbofan and turbojet engines is shown below for reference study.

In the third type of gas engines, turboprop, the propeller is driven a turbine rotated by hot gases. The major portion of the exhaust gases is absorbed by the turbine to produce mechanical work with a very small portion to produce thrust. Below is a schematic diagram of the turboprop engine.

The air intake is the most important part of a subsonic and a supersonic aircraft as it ensures optimum supply of air to the engine for producing required thrust. The design of intakes depends on engine requirements and aircraft design speeds. Since the primary task of air intakes is to supply air for the engine, then the ultimate responsibility for air intake design is attributed to aircraft airframe designer rather than engine designer. Therefore, it is important that both designers work in coordination with each other to reach optimum design (Mattingly 2005).

The intake design such that it ensures that required amount of air is sucked in the engine and the flow is laminar, uniform and stable throughout the intake and when leaving the compressor.&nbsp. &nbsp.&nbsp.
