1)Definition Of A Turbofan Engine:
Turbofan is the combination of two words.”Turbo” means gas turbine engine which takes mechanical energy from combustion and “Fan” means a fan is use which consumes the mechanical energy from gas turbine to accelerate air rearwards.
2)History Of Turbofan Engines:
1)The first turbofan was tested in April 1,1943 by Daimler Benz.
2)In 1960s,low bypass ratio turbofan engines were introduced.
3)Then further modification was done by introducing improved materials and twin compressors.
3)Construction Of A Turbofan Engine:
Fig.1 A Turbofan Engine
It consists of:
1)Intake Duct/Air Inlet:
It is responsible for suction of air.
2)Compressor:
It can be axial or centrifugal.
1)Axial Compressors:
Those compressors in which gas or working fluid flows parallel to the axis of rotation.

2)Centrifugal Compressors:
Those compressors in which the compression is obtained by centrifugal force. They make use of rotating vanes or impel...

...fic impulse(in seconds) is taken along y-axis.It shows the efficiency as a function of speed of different types of jets.It concludes that efficiency per unit distance(per Km/mile) is independent of speed for jet engines as a group.
10)Advantages Of Turbofan Engine:
Turbofan engine is more fuel efficient.
It is quieter due to greater mass flow and lower total exhaust speed.
11)Disadvantages Of Turbofan Engine:
Turbofan engine gives rise to greater complexity due to additional ducting e.g. addition of multiple shafts, heavy blades.
Top speed is limited due to the potential for shockwaves to damage engine.
They are more subject to Foreign Object Damage(FOD) i.e.damage cause to aircrafts when nuts,bolts etc are misplaced during jet blast,engine intake and ice damage.

Do you want your car to pick up speed faster? How about adding a turbo booster on that engine under your automobiles hood. A turbo charger is a very efficient way to gain power. To fully understand the function of this component, lets look at the physics behind it. The Ideal Gas model has much to do in turbo chargers. I will explain the theory and components like the compressor, turbine, intercooler, wastegate, and the BOV.
Ok, we've seen it brought up a million and one times, so, I'm going to give my take on the whole turbo vs. supercharger argument once and for all. Honestly, both devices ROCK. They essentially do the same thing (which is pressurize the intake) when it comes down to it. Argueing that one makes "more power" than the other is utterly redundant, as I re-iterate that they both essentially do the same thing. Look up redundancy in the dictionary and it will say "See Redundant".
There is three propellers which were working by the steam, the rotation of the propellers were working by the movement.
There are many differences between Turbos and Blowers. The first is the power curve. Superchargers build boost as rpm increases in a linear fashion, because they are belt driven from the engine crankshaft. This means that the supercharger is always on and achieves its maximum potential at higher rpm's. The faster the engine is going, the faster the supercharger is turning. T...
For hundreds of years society has been divided into various economic, power, and social classes that represent the worth of individuals. Often there are three social classes depicted, the most common being: upper, middle, and lower class. Social status has become an essential part in the way mankind treats one another. The social class system in Watty Piper’s The Little Engine That Could can be analyzed through the conventional symbolism of color used to illustrate a small train’s journey to the other side of the mountain.
1.Intake: The intake valve opens allowing fresh oxygen rich air mixed with fuel to enter the cylinder.
so they could compress the air at a much higher pressure so the engine can
Process ab: The vapour refrigerant entering the compressor is compressed to high pressure and temperature in an isentropic manner.
The jet engine is a great mechanical piece of engineering. It has been used in almost all aircraft since its invention. This one improvement in aircraft allowed aircraft to fly higher, faster, and more efficient. The turbocharged engine invented by GE was the main building block for other engines. Since its invention, the jet engine has been the workhorse for all jet powered aircraft.
Diesel engines are a marvel of the world and have been since creation in 1892. Today there are several types of these engines including, two-stroke and four-stroke engines as well as the idea of how diesel engines operate. The diesel engine is a necessary component of the shipping industry as well as the daily lives of people.
Firstly, the gas turbine engine operation begins with the air intake process. As of all internal combustion engine, oxygen is required to support the combustion of the fuel and the source of oxygen is from the fresh air that is taken in. Initially, the fan is rotated by a driving shaft that is powered by the turbine of the engine. A negative or vacuum pressure at the intake side is then created by the rotating fan. Next, the surrounding air is drawn towards the inlet and causes it to flow into the gas turbine engine inlet (Cengel & Boles, 2011). At the same time, the pressure on the other side of the fan is increased as it is compressed at a lower pressure ratio and causes the air in the outlet side of the fan to move fu...
turbine via interceptor valves and control valves and after expanding enters the L.P. turbine stage via 2 numbers of cross over pipes. In the L.P. stage the steam expands in axially opposite direction to counteract the trust and enters the condenser placed directly below the L.P. turbine. The cooling water flowing throughout the condenser tubes condenses the steam and the condensate collected in the hot well of the condenser. The condensate collected is pumped by means of 3*50% duty condensate pumps through L.P. heaters to deaerator from where the boiler feed pump delivers the water to boiler through H.P. heaters thus forming a closed

The fuselage, wings, empennage, and engines all make up the pieces of an airplane. They are all important to the well-being of a flying airplane; they are all parts; without one, the plane couldn’t fly. Next time you see an airplane, you can impress anyone with your new knowledge of aircraft.
