the turbo fan engine is a complex synchronization of several components
working together has two parts
a course section that produces power to drive the proposer section
that produces thrust
trust is a force created by the acceleration affair
this phenomenon is simply an application of newton's second law of motion
commonly expressed as
force equals mass times acceleration
it is this force that propels the aircraft
to see how this rosters develop
let's look at the internal workings of pratt and whitney cdw forty one oh two
for both an engine
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
in less than half a second
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 fan duct
picking up speed along the way
the ratio of despair by passing the course through the air passing through
the court
is called the bypass ratio
because of its huge volumes
the bypassed their only needs to accelerate a small amount in order to
develop an enormous amount of corruption
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
blades
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
percent of the total pressurized
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
efficiently ignited
so it matters but diffuser
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
igniting him
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
minute
these blades are connected to a shaft that runs through the center of the and
drives the high-pressure compressor
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
disturbing has two purposes
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
which actually passes through the center
of the high school
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
low-pressure turbine
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
air exiting the fandom
