The turbines are linked by a shaft to turn the blades in the compressor and to spin the intake fan at the front. This rotation takes some energy from the high-energy flow that is used to drive the fan and the compressor. The gases produced in the combustion chamber move through the turbine and spin its blades. The turbines of the jet spin around thousands of times. They are fixed on shafts which have several sets of ball-bearing in between them.
Nozzle - The nozzle is the exhaust duct of the engine. This is the engine part which actually produces the thrust for the plane. The energy depleted airflow that passed the turbine, in addition to the colder air that bypassed the engine core, produces a force when exiting the nozzle that acts to propel the engine, and therefore the airplane, forward. The combination of the hot air and cold air are expelled and produce an exhaust, which causes a forward thrust.
The nozzle may be preceded by a mixer , which combines the high temperature air coming from the engine core with the lower temperature air that was bypassed in the fan. The mixer helps to make the engine quieter. Sir Isaac Newton in the 18th century was the first to theorize that a rearward-channeled explosion could propel a machine forward at a great rate of speed. This theory was based on his third law of motion. As the hot air blasts backwards through the nozzle the plane moves forward.
Henri Giffard built an airship which was powered by the first aircraft engine, a three-horse power steam engine. It was very heavy, too heavy to fly. In , Felix de Temple , built a monoplane that flew just a short hop down a hill with the help of a coal fired steam engine.
Otto Daimler , in the late 's invented the first gasoline engine. In , American Hiram Maxim tried to power his triple biplane with two coal fired steam engines.
It only flew for a few seconds. The early steam engines were powered by heated coal and were generally much too heavy for flight. American Samuel Langley made a model airplanes that were powered by steam engines.
In , he was successful in flying an unmanned airplane with a steam-powered engine, called the Aerodrome. It flew about 1 mile before it ran out of steam. He then tried to build a full sized plane, the Aerodrome A, with a gas powered engine. In , it crashed immediately after being launched from a house boat. In , the Wright Brothers flew, The Flyer , with a 12 horse power gas powered engine.
From , the year of the Wright Brothers first flight, to the late s the gas powered reciprocating internal-combustion engine with a propeller was the sole means used to propel aircraft. It was Frank Whittle , a British pilot, who designed and patented the first turbo jet engine in The Whittle engine first flew successfully in May, This engine featured a multistage compressor, and a combustion chamber, a single stage turbine and a nozzle.
At the same time that Whittle was working in England, Hans von Ohain was working on a similar design in Germany.

Cite This! Try Our Sudoku Puzzles! To find out more about each of the four steps in the creation of thrust by a jet engine, see below. SUCK The engine sucks in a large volume of air through the fan and compressor stages. A typical commercial jet engine takes in 1. The mechanism by which a jet engine sucks in the air is largely a part of the compression stage. In many engines the compressor is responsible for both sucking in the air and compressing it.
Some engines have an additional fan that is not part of the compressor to draw additional air into the system. The fan is the leftmost component of the engine illustrated above. The compressor is shown in the above image just to the left of the fire in the combustion chamber and to the right of the fan. The compression fans are driven from the turbine by a shaft the turbine is in turn driven by the air that is leaving the engine.
Compressors can achieve compression ratios in excess of , which means that the pressure of the air at the end of the compressor is over 40 times that of the air that enters the compressor.
At full power the blades of a typical commercial jet compressor rotate at mph kph and take in lb kg of air per second. Now we will discuss how the compressor actually compresses the air.
