Introduction
A turbofan engine is found on all commercial airliners around the globe. The turbofan engine works by way of a thermodynamic cycle where air is taken into the engine, then compressed, combusted, expanded, and finally exhausted out of the engine. This creates thrust in the engine and causes the vehicle to propel forward or backwards. These steps are carried out by the five major engine components: the fan, compressor, combustor, turbine, and exhaust nozzle. The compressor and turbine contain high and low pressures. These components are shown in Figure 1. In Figure 2, it shows all the 5 main components of the engine starting from 1 and then towards the end to 5.
Discussion
The Fan
The fan plays an important role in producing the majority of the thrust generated by a turbofan engine. This fan is directly connected to the low pressure compressor and the low pressure turbine. Air enters the engine by passing through the fan, most of the air travels around the core of the engine when it is passes through the fan. The air that travels around the core of the engine is also known as bypass air. Bypass air is accelerated out of the back of the engine by the fan, which creates the thrust. Any remaining air enters the core of the engine and after enters the low pressure compressor.
Compressor
The compressor main job is to prepare the air for combustion by adding energy in the form of pressure and heat. The compressor has two 2 subdivisions known as the low pressure compressor and the high pressure compressor. The low pressure compressor is connected to the fan and the low pressure turbine. The low pressure compressor pushes the air further back into the engine by the rows of spinning blades. As the air is
