the turbo fan engine is a complex synchronization of several components

関係詞節（制限と非制限）

a course section that produces power to drive the proposer section

trust is a force created by the acceleration affair

this phenomenon is simply an application of newton's second law of motion

it is this force that propels the aircraft

let's look at the internal workings of pratt and whitney cdw forty one oh two

the first component and the engine is the huge nine foot diameter fan

that rotates twenty eight hundred times a minute at takeoff

this giant fans suck cinema varaku vacuum out there

as the air races through the massive man it separated into two streams

only fifteen percent of the air flows into the interior core of the engine

the remaining eighty five percent of the year

used article on the outside of the corner

and is forced through whatever narrowing space

the ratio of despair by passing the course through the air passing through

the bypassed their only needs to accelerate a small amount in order to

me while the other fifteen percent of the year has entered the first component

in the engines cork the low pressure compressor

here the air passes through several smaller stages

each consisting of a set of rotating blades in between a set of stationery

each stage compresses the air forcing its temperature and pressure to rise

after passing through the low pressure compressor the air matters the

high-pressure compressor which rotates faster and is responsible for seventy

after the air has passed through both compressors it is thirty five times

higher in pressure and upper house of degrees hotter than the outside air

the compressed air is now with the right pressure but it is moving too fast to be

where it slows down while remaining at the optimum temperature and pressure

the air then enters the combustor where it energy level has greatly increased

this is accomplished by adding fuel through a series of injectors and

further increasing the temperature of the mixture by sixteen hundred degrees

the higher the pressure of the air the more energy will be started during

combustion and the more efficient this process becomes

this is why the compressors were used to increase the heirs pressure

the superheated and compressed air mixture is ready for the next day

blasting through the high-pressure turbine

the high-energy air spins the blades that over ten thousand revolutions per

these blades are connected to a shaft that runs through the center of the and

in fact he only purpose of the high-pressure turbine

is to extract enough energy from the air to turn the high-pressure compressor

together these components make up the high school

next the air passes through the larger low-pressure turbans

first of extract enough energy from the air to power of the low pressure

compressor at the front of the engine core

these two components are connected via a second shaft

however the second and more important job with the low pressure turban is

concerned the large titanium fan blades upfront

the families connected to the same shaft as the low pressure compressor and

together these three components make up the low score

finally become busted air races out through the exhaust nozzle at the back

of the engine to be accelerated one last time

the speed at which this gas tax it's the nozzle is called chapel ostatic

this exhaust stream produces only twenty percent of the engines total thrust

remaining eighty percent is produced by the large volume of accelerated bypass
