Our study will revolve around the design of a turbofan that is a type of gas turbine engine commonly used in airplanes and energy production.
Turbofan is a type of gas turbine engine that itself is a common type of air-breathing engine. In order to understand its design, its construction and the function of its important components should be understood. The important parts of a turbofan are as follows:
Figure 1 shows the location of each of these components in a turbofan. To understand the importance and function of every component mentioned above, we will briefly describe the working principle of a turbofan.
Air from the atmosphere is received by the engine through its inlet and is divided into bypass stream and the engine core stream. The fan along with the compressor increases the pressure of the air in order to enable a greater air mass flow rate through the engine core, which in turn in required for efficient fuel combustion and the production of sufficient thrust. The compressed air from the compressor is brought into the combustor – or the combustion chamber – where a fine stream of fuel is added into the compressed air and ignited using a flame torch setup. The temperature of the air rises substantially during combustion and as it tends to expand, it is directed towards the turbine which uses the energy of this very hot air to drive the compressor. The rest of the energy gained by the air makes it expel the exhaust nozzle at a high speed and provides the thrust required to accelerate the plane.
Intake is primarily responsible for channeling the air from the atmosphere to the fan of the engine at a high pressure (Gordon). In addition to having an aerodynamically efficient front profile, its shape has to be appropriate for required air mass flow required by the engine as well as for required fluid velocity translation to a lesser magnitude. Air enters the inlet at a high speed and is slightly slowed down to assist the fan in
