What is Turbine Engine?

Turbine is actually something that when a force applied to it, then it will ROTATE...that is TURBINE...

for example, windmill. When big amount of air (force) applied to the windmill, the windmill will rotate. That is TURBINE

so how about TURBINE ENGINE? turbine engine use the same principle. When the HOT air passed by the TURBINE, the turbine will rotate. As the turbine rotate, the compressor also rotating (because of the shaft connected directly between COMPRESSOR and TURBINE). So as the compressor rotate, more air will be SUCKED by the engine and it will keep rotating.

If you are a car's fan, you must know about TURBO-charger that is used widely in car, right? TURBO also come from word 'TURBINE'. Turbo use same principal. Turbo consist of two part BASICALLY; compressor and turbine. Turbine located after the exhaust and compressor before the air intake. As the exhaust air pass through the turbine, the turbine will rotating, thus will rotate also the compressor. When the compressor turning, more air will be SUCKED to the engine. More air means more oxygen. More oxygen will create a very good COMBUSTION because to BURN something, you need oxygen.


How people get an idea about developing TURBINE ENGINE?

  • Observation of natural world (Squid)
  • Newton's Third Law


Newton's third law of motion states that for every action there is an equal an opposite reaction. Jet propulsion applies this law by accelerating a quantity of air through an orifice (or nozzle). The acceleration of the air is the action and forward movement is the reaction.

In nature, a squid propels itself through the water using a form of jet propulsion. A squid takes (SUCKS) sea water into it's body and uses its muscles to add energy to the water(COMPRESS), then expels the water in the form of a jet. This action produces a reaction that propels the squid forward.

SQUID = suck water --> compress it --> release the water --> producing forward movement

TURBINE engine = suck air(inlet) --> compress --> COMBUSTION mixture fuel/air --> to release the air with very high speed --> producing forward movement


p/s: Many technological developments are made by observations of the natural world. A squid propels itself through the water by jet reaction.

As early as 250 B.C., a writer and mathematician named Hero devised a toy using this reaction principle. The toy, called the aeolipile, consisted of a covered kettle of water that was heated to produce steam. The steam was routed through two vertical tubes into a spherical container. Attached to the sphreical container were several discharge tubes arranged radially around the container. As steam filled the container, it would escape through the discharge tubes causing the sphere to rotate.

A modern example of Newton's reaction principle is observed when the end of an inflated balloon is released. As the air in the balloon rushes out the opening, the balloon flies wildly around a room. In spite of the everyday examples, scientific efforts to apply Newton's reaction principle to mechanical designs were largely unsuccessful until the 20th century.
