Answer . A propeller is completely external and is the main source of propulsion for a airplane with a piston or turbojet engine. A turbofan is more enclosed and provides some propulsion along with also cooling the jet engine that is the main source of propulsion.
A turbojet is one of the oldest kinds of jet engine designs.The air flow enters the jet engine at one end and is compressedwhile it travels through rows of rotating blades (calledcompressors; sometimes referred to as stages). It is then ignitedin the combustion chamber and as the gas expands and s…peeds up, itcauses the turbine blades to turn, which provides the torque to thecompressor stages. The force of the exhaust gases exiting is whatprovides the forward motion of the engine and is referred to as thrust . A turbofan jet engine is the most widely used jet engine onmodern aircraft today. It uses a fan placed directly in front of aseries of compressors to compress the air. The operation is similarto the turbojet engine, except not all of the air moved by the fangoes into the engine's combustion chamber. A portion of the airflows over the engine itself, called bypass air . Bypass airalso produces thrust in conjunction with the exhaust gas pressure. Turbofan engines come in two varieties: high bypass and low bypass . With high bypass turbofans, the majority of the total engine thrust(as much as 80%) is produced by the bypass air. With low bypassturbofans, the majority of the thrust is produced by the exhaustgases. Large commercial airliners (such as the Boeing 747 JumboJet), large military cargo jets (such as the Lockheed-Martin C-5Galaxy) and some small military tactical fighters jets (such as theFairchild-Republic A-10 Thunderbolt II) use high bypass turbofansbecause they offer better subsonic efficiency at low to mediumaltitudes, are quieter, and still offer strong thrust at the costof supersonic capabilities. Low bypass turbofans are popular on small, high-performancetactical fighter aircraft (such as the Lockheed-Martin F-22ARaptor) and sacrifice fuel efficiency for improvements in thefollowing areas: high altitude performance, supersonic performance,supersonic efficiency, and afterburning fuel economy. Inafterburning engines, fuel is sprayed into the exhaust stream andproduces the famous flame trail that jet engines are known for.Activating the afterburner can increase thrust output by as much as50%. Turbofans as a whole offer better efficiency than turbojets at highsub and transonic speeds, and at low supersonic speeds with littlesacrifice in thrust performance. (MORE)

it works by how the pilot operates it. Engine start on the top of the head location. the pilot pulls the switch down know as engine ignition. It would start the turbofan and it would be blowing fast That is completely wrong!! Whoever wrote the above knows nothing about Aerospace Engineering and nee…ds to find something different to do in their lives. The Turbofan jet engine is the most commonly used engine on a commercial airliner such as a Boeing 747 or a 737. Basically an enormous fan sucks in lots of air, which is then separated into two groups: around 80% goes into the bypass duct, and stays cool, while the small amount that remains goes through the core. In the core, the air is pressurized first in the Low Level Compressor, then pressurized even more in the High Level Compressor. This extremely pressurized air is then forced through the Combustor, where fuel is injected into it and then ignited. This creates very hot air, and is forced through a series of Turbines. After this, the cool air from the bypass duct is mixed with the hot air from the core and is forced out of the Nozzle in an hourglass shape to create thrust. This is exactly how a Turbofan Engine works. (MORE)

To understand how is the turbofan working, firsly you should know how is theturbojet working, so here you are the explanation. . A turbojet is essentially a tube with a constriction in it with a turbine at the beginning and a turbine at the end, connected together on the same axle. Fuel burns in …the combustion chamber behind the constriction in the tube, sending hot, expanding gases mostly out the back end of the tube. The hot gases push on all sides of the tube including the constriction in front, and so the sum of all the pressure forces on the tube points forwards, providing thrust, just as a rocket engine works. The turbine on the exhaust side uses a fraction of the energy of the exiting exhaust to spin the turbine blades and axle, and in turn this spins a turbine in front which compresses the air needed to burn the fuel. Compressing the input air increases the amount of expansion of the gases in the combustion chamber -- the fuel burns fast because there is plenty of oxygen, and there is a lot of expansion of the gas in the burning and decompression. A turbofan engine is just a turbojet with a big fan in front attached to the turbine axle. A fraction of the exhaust energy is used to spin the fan which blows a huge amount of air past the engine, which does not participate in the combustion but which provides quite a lot of thrust (just the total force the jet engine pushes forwards with). I suspect that this also helps the fuel effiency of the engine. Smaller airplanes put a propeller in front instead of the turbofan's big fan and air diversion assembly. (MORE)
Nobody actually knows the reason why the day was split into 12 hours and each hour split into 60 minutes and then each minute into 60 seconds. The best guess is that it was the Babylonians who worked out that there were 12 full moons in a year which gave them a 360 day year. They also knew the relat…ionship between the radius of a circle and its circumference, which split the circle into six segments. Dividing this by two gave them 12 segments, which also fitted well with their religious beliefs that the number 12 had some kind of special significance. Who Invented the Clock? - The Sun Even though we are fairly sure that the Babylonians had some sort of sun dial it was the Egyptians that really took timekeeping to a new level with the invention of the obelisk. This was a tall slim structure with a pointed top that told the time by throwing a shadow that moved in a semi-circular rotation, allowing the Egyptians to segment a horizontal disk and thereby tell the time. It was the Egyptians that discovered the Meridian Line, a line joining North and South, by observing that the shortest shadow cast by the obelisk would always point in the same direction, regardless of the season . It was about this point that the center of the dial was marked as midday. They also discovered the longest and shortest days, those where the shadow was either shortest (summer solstice) or longest ( winter solstice ) measured at midday. As time passed and knowledge was gained the Egyptians created smaller sun dials, although it was soon learned that telling the time accurately with a small device was much harder due to the fact that even though the shadow cast was much sharper, it was much more difficult to accurately segment the disk. The sun dial moved from Egypt into Greece and later Rome. The Romans improved the device further by developing the hemicycle, a sort of hollowed out sun dial in the shape of a half bowl that added further to the accuracy of timekeeping and also allowed much smaller devices to be made. Who Invented the Clock? - Water Clocks (Clepsydra) Although the Egyptians did use water clocks in around 1400BC, the advancement of mechanical theory by people like Archimedes (250BC) attracted more scientists and inventors to take these principles and apply them to the process of measuring time. The principle was simple - fill a container with water and allow it to flow at a constant rate into another chamber that then operated some sort of float mechanism that moved a lever to show the hours. Various methods were used to maintain a constant water flow, the most common being the use of a constantly overflowing funnel, thereby ensuring that the same head of water was maintained at all times. The only problem with these clocks was their poor accuracy. As time went by various methods were used to make the flow of water more accurate but it was the Chinese that appear to have made the most accurate water clocks around the 11th Century. A Chinese monk by the name of Su Sung designed a huge clepsydra in the year 1092. Five stories high with numerous automata, the device was run by a very large water wheel that moved similarly to that of a modern clock escapement. Every quarter of an hour the wheel would turn, advancing all the other cogs and gears and opening and closing doors that released the automata. It may be that this was the first mechanical clock as we know it today with its gears and pulleys, even though it still relied on water as its power source. Nevertheless, it is the first known use of a mechanical escapement and as such proved to be many hundreds of years of its time. Who Invented the Clock? - Mechanical Clocks The mechanical clock we know today was probably a result of a development of inventions and theories throughout the centuries, for we do not know precisely when the clock as we know it was first invented. In the 13th Century a clock was devised that used weights to drive a drum containing mercury. The mercury passed into each segment of the drum and slowly filtered through holes in the separating pieces, thereby controlling the rate at which the drum turned. This is of course a similar escapement to the one devised by Su Sung in 1092. It is the escapement that clearly separates a water clock from a mechanical device. The first fully mechanical escapement was the verge and foliot, whereby a horizontal bar, or foliot, was impulsed by a vertical bar, or verge, with small pallets on a large wheel powered by a weight. The foliot had adjustable weights hanging off each end that gave it inertia and helped keep a constant timekeeping beat. Most of these early clocks were 'clocks for the people'; they were quite large, expensive and certainly were not clocks made for personal use. The advent of the clock for the home came with advances in escapements and a new power mechanism - the spring driven clock, the earliest known example dated at 1450, on display at the British Museum . The spring driven clock was certainly a technological advance but timekeeping didn't improve as a result. As yet there was no method of keeping the power to the escapement constant. As the spring wound down so the clock would slow down. After it was wound up the clock would run faster. The solution was the fusee , a device that spread the force exerted by the unwinding spring in a more even manner. It is thought that the fusee was invented by Jacob Zech of Prague, however others think that it was Leonardo DaVinci that first came up with the device. Da Vinci is credited with a drawing of such a mechanism in manuscripts dated around 1485. It was Galileo Galilei that first studied the motion of the pendulum in 1602. His studies were followed later by Christiaan Huygens , who patented the first clock using the device. Huygens' clock, using a short pendulum inside a wooden case proved to far more accurate than existing clocks and this led to the development of better and more accurate clocks. Later the pendulum's length was increased and accuracy increased again. The increased length of pendulum required a longer and larger wooden case and it was this development that gave birth to the longcase clock . The pendulum has remained a popular method of keeping time for the past 300 years, and it has undergone improvements throughout that time, being made of differing materials to compensate against temperature differences and also the development of the 'free-pendulum' whereby as little friction as possible exists to slow the pendulum. So as you can see, "who invented the clock" is not an easy question to answer! Happy Collecting! (MORE)
A turbofan is an Cold Air Unit that lowers the temperature of the air passing through it. The air is made to work (reducing temperature) by turning the turbine and made to work even more (another drop in temperature) by turning the fan.

There are two types of turbofan engines- high bypass and low bypass engines. About 80 percent of the total engine thrust from a high bypass turbofan engine is produced by the bypass of air around the core. These types of engines generally have a large fan in the front to pull in large volumes of …air to produce such a powerful jet stream out the back. The front fan is driven by the compression, combustion, and expulsion of the hot gases out the back of the core. About 20 percent of the air pulled in from the front fan is used to drive the core. High bypass turbofan engines are used on almost all commercial jet aircraft because they burn less fuel. A low bypass engine is exactly the opposite. The core is used to drive a smaller fan in the front which only about 20 percent of the total volume of air pulled in is bypassed. The remaining 80 percent of the air being drawn into the engines core is compressed, combusted, and the hot gasses expelled out the back to produce the necessary thrust to propel a jet forward. Low bypass turbofan engines are found on jets that require supersonic speeds. These engines are incredibly powerful but at the cost of a high fuel burn rate. (MORE)

The first airplane flight was in one of George Cayley's gliders in1853 at Bromton Dale. German engineer and inventor (25 patents)Otto Lilienthal would later write the seminal Birdflight as theBasis of Aviation in 1889 and developed what would become thehang gliders we see today. Orville and Wilbur… Wright cited his workas the inspiration for thier interest in manned flight. The Wright brothers are credited with the first powered,controlled, sustained heavier-than-air flight at the end of 1903,but they may have been preceded nine months by a recluse NewZealand farmer named Richard Pearse. Unlike the Wrights' plane, hismonoplane aircraft with its moveable control surfaces was much morerecognizable as a progenitor of modern aircraft. Reconstructions ofhis craft and his engines showed that his designs were sound andthere's no reason they shouldn't have gotten the pilot airborne,despite the lack of foils for wings. In the late 1700s, George Cayley designed some similarlyaerodynamically sound lifting surfaces around inclined planesrather than the more efficient foils we use today. The airplane wasn't an invention as much as an innovation. There isno single person nor people who can be credited with creating theairplanes of today.

A turboprop aircraft, such as a Cessna, cannot fly as fast as a turbofan aircraft, such as a Boeing. Because of this, lift cannot be maintained at high altitudes. As you go higher, you can go faster because there's less air to slow you down. But if you don't go fast enough, then the plane will stall… and keep falling until it reaches an altitude at which lift can be maintained at its current speed. (MORE)
Geared turbofans have planetary reduction gearboxes to allow the fan (which pulls the airplane through the sky) will run slower than the compressor shaft. This does two things for you. It lets the shaft turn faster, and more efficiently, than the fan can safely turn, and it increases the horsepower …available to the fan. Say you have a shaft that produces 1000 horsepower at 100,000 rpm. If you turn a three-foot-diameter fan 100,000 RPM it will explode like a grenade. Installing a 10:1 reduction gear will allow the fan to run at 10,000 RPM but it will have 10,000 horsepower. (Every time the compressor shaft turns it puts out 1000hp; if it turns 10 times to make the fan turn once, it puts 10,000hp out.) (MORE)

The difference between the low and high bypass turbofans is simply in the amount of air which goes into the engine versus the remainder that goes around (bypasses) the engine. In high bypass engines ( an engine on any large commercial jet) only 20% around 20% of air goes into the engine with 80% by…passing it.

The first video game is an often debated topic. The idea of computer that could play games actually dates back to the inventor of the computer himself, Charles Babbage. While designing his never completed Analytical Engine in 1837, a machine he hoped would be able to carry out any mathematical funct…ion, he realised it would be capable of playing simple games such as tic-tac-toe and chess. The first actual computer that played a game was called the Nimatron. It was developed and built by Edward U. Condon in 1940 to play the Chinese game of Nim. The game was displayed 'visually' by illuminating columns of lightbulbs. That same year it was demonstrated at the New York World's Fair where it was played by 50,000 people. The first computer game to be displayed on an actual screen was called OXO. It was written for the EDSAC computer by Alexander S. Douglas in 1952 for his Ph.D thesis on human-computer interaction for the University of Cambridge. Spacewar! developed by Steve Russell in 1962 is the first computer game developed for an already existing system; the PDP-1 computer. This also made it the first game to be distributed. The source code was made available to anyone who requested it. Computer Space made in 1971 by Nutting Associates was the world's first commercially sold video game of any kind. The coin-operated video game was created by Nolan Bushnell and Ted Dabney, the later founders of Atari. A year later in 1972 the Magnavox Odyssey, created by Ralph H. Baer, became the first commercially sold video game console. (MORE)
Most turbofan engines have parts running at more than one speed. The inner most compressor stages and the first turbine stages usually turn faster than the outer stages. The more popular engines seen on airliners use three stages, and three different speeds at any given time. Watch a modern airliner… engine during engine start and you can hear the inner stages begin to spin up before you will see the outer fan stage begin to rotate. It depends on the engine, but the largest fan stage which is seen in the intake will be less than 10k rpm, often less than 5k. (MORE)

A turbofan engine is the most modern variation of the basic gas turbine engine. As with other gas turbines, there is a core engine, whose parts and operation are discussed on a separate page. In the turbofan engine, the core engine is surrounded by a fan in the front and an additional turbine at the… rear. The fan and fan turbine are composed of many blades, like the core compressor and core turbine, and are connected to an additional shaft. All of this additional turbomachinery is colored green on the schematic. As with the core compressor and turbine, some of the fan blades turn with the shaft and some blades remain stationary. The fan shaft passes through the core shaft for mechanical reasons. This type of arrangement is called a two spool engine (one "spool" for the fan, one "spool" for the core.) Some advanced engines have additional spools for even higher efficiency. How does a turbofan engine work? The incoming air is captured by the engine inlet. Some of the incoming air passes through the fan and continues on into the core compressor and then the burner, where it is mixed with fuel and combustion occurs. The hot exhaust passes through the core and fan turbines and then out the nozzle, as in a basic turbojet. The rest of the incoming air passes through the fan and bypasses , or goes around the engine, just like the air through a propeller. The air that goes through the fan has a velocity that is slightly increased from free stream. So a turbofan gets some of its thrust from the core and some of its thrust from the fan. The ratio of the air that goes around the engine to the air that goes through the core is called the bypass ratio . Because the fuel flow rate for the core is changed only a small amount by the addition of the fan, a turbofan generates more thrust for nearly the same amount of fuel used by the core. This means that a turbofan is very fuel efficient. In fact, high bypass ratio turbofans are nearly as fuel efficient as turboprops. Because the fan is enclosed by the inlet and is composed of many blades, it can operate efficiently at higher speeds than a simple propeller. That is why turbofans are found on high speed transports and propellers are used on low speed transports. Low bypass ratio turbofans are still more fuel efficient than basic turbojets. Many modern fighter planes actually use low bypass ratio turbofans equipped with afterburners. They can then cruise efficiently but still have high thrust when dogfighting. Even though the fighter plane can fly much faster than the speed of sound, the air going into the engine must travel less than the speed of sound for high efficiency. Therefore, the airplane inlet slows the air down from supersonic speeds. (MORE)
