A turbofan engine Pratt and Whitney for the F-15 Eagle

Jet engines take air mass with relatively few and accelerate it with a large amount, in which a driver took a large mass of air and accelerate it in small amounts. Disposal of high speed of a jet engine makes efficient at high speeds (especially supersonic speeds) and high altitude. On aircraft that require low and short-distance flying, drivers who use gas turbines, which is generally known as a turboprop, is more common and more efficient. Very small aircraft usually use to run the piston engine driving remains small turboprop increasingly smaller with the development of engineering technology.

Combustion efficiency of a jet engine, like any other internal combustion engine, large influenced by the ratio of the compressed air volume with the volume of disposal. In the turbine engine of air compression and shape, Äúduct, Au through the combustion chamber to prevent back-flow from it and make possible continuous combustion and facilitation process.

Modern turbojet engine modular in concept and design. Core revenue-major power, as in the entire jet engine, called a gas generator. As well as additional modules such as a reduction gearset drive (turboprop / turboshaft), the fan through, and, Äúafterburner, Au. Types of additional equipment installed on aircraft usage.

Or jet engines, also known as a gas turbine engine is developed not only for aircraft but also for ships and land vehicles, especially for heavy vehicles such as tanks and engines and power plants for industrial machinery. There are four types of turbojet engines such as turbojet engines and turbofan engines of the energies obtained from the reaction obtained from the driving force of his jet blast. Other types of turboprop and turboshaft is working with other principles of heat energy from the gas used to play / drive a turbine connected to a propeller or also known as the power output shaft.

Rekasi simple jet engine and developed it into a twin-spool low by pass ratio turbojet. Now from turbojet low by-pass ratio, developed into a triple-spool front fan high by-pass ratio turbojet, or more commonly known as high-bypass turbofans and fanjet. The concept is still a prop-fan engine and the UDF (unducted fan) and contra-rotating fan.

Turbojet engine jet engine which is the simplest, often used for aircraft, high speed. Examples of this machine is the Rolls-Royce engines Olypus 593 used for the Concorde. Another version is the Olympus Marine engines that have power dk 28,000 (horse power, equivalent to 21 MW) is used to drive a modern warships with 20,000 tons deadweight with a high-speed operation.

Jet engines actually begins when a French engineer, Rene Lorin first proposed the patents for jet propulsion engine in 1913. Patented machine is a machine athodyd (aero-thermodynamic-duct) that has no rotating parts, or more popularly known as pulse jet engine. This type of machinery which later developed and used as the main force driving the engine flying bomb Germany, V-1 is used to bomb England.

Unfortunately the engine concept is less suitable for Lorin berpropulsi jet aircraft because it is inefficient in low speed. While at the time Lorin, not possible to make such a machine. Besides, have not introduced heat-resistant material made and developed. Lorin type machine has a similar concept with a Ramjet engine was introduced.

Furthermore, an officer in the British Royal Air Force (Royal Air Force / RAF), Frank Whittle and a student of aerodynamics University of Gottingen, Hans von Ohain (Germany) and the Italian engineer, Secondo Campini developing jet engines and the principles and concepts known in those days now that is using rotating components such as compressors and turbines.

History records that Frank Whittle filed a patent in 1930 but initially received little attention from the British Air Ministry. As a result, the discovery is not a secret Whittle and military jet engines detaik concept leaked and published in various scientific and technological journals 1.5 years later. But thanks to former colleagues at RAFserta financing for the development of the OT Falk & Partners Ltd.. Whittle then formed a company Power Jets, who finally succeeded in developing a jet engine and got the contract in the British Royal Air Force. The engine is a type W-1X which then prompted ditahun 1942, licensed by the United States.

Jet engine is a type of internal combustion engine breathing air used in aircraft. The principle of all jet engines is essentially the same: they accelerate the mass (and the combustion air) in one direction and the Newton's third law of motion of the engine will experience a boost in the opposite direction. Which includes among other jet engine turbojet, turbofan, rocket, Ramjet, and pump-jets.
This engine air from the front and compression. Air combined with fuel and burned. Combustion adds many improvements to the energy of the gas and then discharged into the back of the machine. This process is similar to the four-movement cycle, with induction, compression, ignition, and the disposal occurs on an ongoing basis. Engines produced since the acceleration impulse through the air; force equal and opposite is the impetus generated for the machine.

Machine type is W-1X was first tested in December 1940 and then modified and declared eligible for use as a power in aircraft. British jet-engine plane was first flown by test pilot Gerry Sayer on May 15, 1941 in Gloster E.28/39. Secondo Campini plane from Italy to make a jet engine in 1933 and joined with designer Giavasi Caproni aircraft makes CC-2 aircraft jet engine first flying on August 27, 1940. Italian media noted as the first jet aircraft in dunia.Hans von Ohain registering jet engine design patented in 1935. Even though the engine is considered similar to the concept Whittle, but there are many detailed differences in engine design. Then one of his professors, who knew Ernst Heinkel, the aircraft industry company owners have requested that Heinkel Hans von Ohain involved in the project to make engines. In March 1937, a powerful engine pushing 550 pounds successfully made, then push the power engine of 1980 pounds and are considered less successful and powerful engine pushing 1100 pounds full of modifications made to the aircraft and Heinkel He. Ie 178 turbojet engine HES-3b. On August 27, 1939, aircraft Heinkel He-178 and then successfully made its inaugural flight on the runway with the pilot test Marienehe Luftwaffe (German Air Force), Eric Warsitz. The development of jet engines and the first in the world is kept secret by the Nazis for military purposes. Five days later on September 1, 1939, Hitler's armies invaded Poland who became the beginning of World War II. Secrecy is what makes the common view in the world that Italy and the UK as a pioneer in machine technology jet.Di Asia, Japan will begin to look for a jet engine, especially military aviation interests in 1937 when Japan bought a Brown-Boveri machine equipped with a turbocharger from Switzerland. From this basis, not after getting mengeherankan from allies, the German form of the draft Messerschmicht fighter Me-262, Japan developed a jet engine for Ne-20 jet fighter mentenagai first Kikka, which is similar to the German fighter jet.

info
The South Korean defense officials have confirmed that a fighter jet F-15 has crashed in the country's southeastern coast. Ministry of defense and the Air Force said the plane was leaving the Daegu Air Base, about 300 kilometers southeast of Seoul Wednesday night, for flight training.

The plane disappeared from radar screens after about 40 minutes and seemed to fall into the Sea of Japan. Both pilots had not been found. Confirmation of the crash was announced after the rescue team found the fragments of the plane off the coast near the city of Pohang.

F-15K made in the United States was regarded as one of the main aircraft most sophisticated fighter jet. South Korea plans to buy 40 aircraft by the year 2008. The missing plane was one of the main of four purchased.
