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.

The Physics Behind the Power of an Engine Insert the key, turn, and vroom. And down the road you go. Most people take for granted the strange conglomeration of metal and plastic under that sheet of metal, either in front or back of their vehicle. The engine, as you may have guessed, is a modern marvel- so to speak. They’re found in cars, trucks, boats, airplanes.
Pressure is a main factor in turbo chargers. Pressure is the force exerted on a surface divided by the area of the surface (force per unit area). Decreasing the volume increases the pressure. The average speed of the molecules do not change. If we increase the number of particles in a same volume, we expect the pressure to increase because there would be more frequent collisions between the particles and the walls of the space. Temperature is also very important. If the temperature of the gas increases, the speeds of the particles also increase. Pressure and volume are inversely proportional, (by Boyle’s Law) as one increases, the other must decrease. Gases want to flow from a high pressure area to a low pressure area. The greater the difference, the faster they flow. I...
...e practically endless, and each person will have his or her own opinion on which is better based on the desired outcome of the setup. It is almost is basically a given that a turbocharger will produce more peak power, but the power band on the supercharger is the main property it has going for it. Each set up is complicated to some extent, but the supercharger is an easier way to learn what you’re doing as it is much less work than installing a turbocharger. Turbochargers are more in depth and require more tuning and more modifications in order for it to operate efficiently and correctly. If the end game is to produce as much power as possible the turbo is going to be the best bet, but if the goal is to reach peak power as quick as possible the supercharger might fit the bill better. At the end of the day everybody has their own opinion and nobody is going to win.
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".
The enthusiast driver has to know their machine and their own personal limits when considering these two units. Although they are very similar, turbos and blowers are also very different.
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.
There is three propellers which were working by the steam, the rotation of the propellers were working by the movement.

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.

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.
1. Impulse Turbine:- In Impulse Turbine steam expands in fixed nozzles. The high velocity steam from nozzles does work on moving blades which causes the shaft to rotate. The essential features of impulse turbine are that all pressure drops occur at nozzles and not on blades. A simple impulse turbine is not very efficient because it does not fully use the velocity of
