Q & A
¿Qué es el sistema anti-hielo del motor de un avión?
-El sistema anti-hielo del motor es un mecanismo diseñado para prevenir la formación de hielo en la parte delantera del motor de un avión. Funciona calentando la parte delantera del motor para evitar que los depósitos de agua se congelen al entrar en contacto con el aire frío y húmedo.
¿Por qué es necesario el sistema anti-hielo en los motores de avión?
-Es necesario para evitar que el hielo se acumule en la parte delantera del motor, ya que si se forma una masa grande de hielo que se desprende y es ingerido por el motor, puede causar daños significativos al motor.
¿Cómo funciona el sistema anti-hielo en la parte delantera del motor?
-El sistema anti-hielo utiliza aire comprimido y caliente proveniente del compresor del motor. Este aire caliente se dirige a través de tubos y se distribuye en la parte delantera del motor, incluyendo los montantes, la sección central y las vanes de guía de entrada, para prevenir la acumulación de hielo.
¿Dónde se encuentra el punto más caliente del compresor del motor y cómo se utiliza para el sistema anti-hielo?
-El punto más caliente del compresor se encuentra en el punto de descarga del compresor. El aire altamente comprimido y caliente se extrae de aquí y se dirige al sistema anti-hielo para calentar la parte delantera del motor.
¿Qué es la válvula de control anti-hielo y cómo funciona?
-La válvula de control anti-hielo es una válvula que se abre cuando se activa el sistema anti-hielo. Controlada por un solenoide que a su vez es activada por un interruptor en la cabina de vuelo, permite que el aire caliente del compresor fluya hacia la parte delantera del motor.
¿Cómo se distribuye el aire caliente en la parte delantera del motor?
-El aire caliente se distribuye a través de un colector que se ramifica y se dirige a los montantes, la sección central y las vanes de guía de entrada. Este aire caliente circula y finalmente se vierte de vuelta al compresor a través de las vanes de guía de entrada perforadas en su borde trasero.
¿Qué es la válvula de control de flujo y cómo ayuda a regular la temperatura en la parte delantera del motor?
-La válvula de control de flujo es un mecanismo que regula la cantidad de aire caliente que fluye hacia la parte delantera del motor. Funciona mediante un resorte metálico que se expande y contrae con el calor, girando y ajustando los dedos que controlan el flujo de aire, lo que a su vez regula la temperatura.
¿Cómo se asegura que la parte delantera del motor no se sobrecalente?
-Se utiliza una válvula de control de flujo que, mediante un resorte metálico que reacciona al calor, ajusta la cantidad de aire caliente que se permite fluir hacia la parte delantera del motor. Esto evita que la parte delantera del motor se sobrecalente.
¿Qué componentes específicos del motor se calientan mediante el sistema anti-hielo?
-Los componentes específicos que se calientan incluyen los montantes, la sección central, la cubierta del morro y las vanes de guía de entrada. El aire caliente circula a través de estos componentes para prevenir la formación de hielo.
¿Cómo se vierte el aire caliente después de haber calentado la parte delantera del motor?
-El aire caliente se vierte de vuelta al compresor a través de las vanes de guía de entrada, que tienen orificios perforados en su borde trasero, lo que permite que el aire caliente se escape y se reintegre al flujo principal del motor.

welcome back everybody today we're going
to be looking at another ntis
system but this time
in the engines
[Music]
what is the engine anti-ice system
why do we need it well when the
airplanes are flying along
they can get into conditions where you
have
ice forming in the front of the engine
the moist
cool air impacting the front of the
engine you can actually have
water droplets depositing and freezing
on contact
on the front of the engine on the struts
on the inlet on the nose dome
everything that makes contact with the
air as it's
coming through if enough of that
ice builds up to a big chunk
and then breaks off and gets ingested by
the engine
it can cause a lot of damage to prevent
that
the front of the engine has an anti-ice
system which prevents the buildup of ice
the formation of ice
and it does that by heating up the front
of the engine and i'm going to show you
how it does that um
normal engine operation basics you have
the
inlet coming in getting compressed
through the different stages
as you go through the compressor the
more you compress the air
the temperature goes up higher up
pressure
the higher the temperature until you get
into the rest of the engine
today we're going to look at where in
the engine
the the nti's system it heats up the
front of the engine by using
that comp heated compressor air
at the hottest point of the compressor
it's right at the discharge point of the
compressor
and it blows it through these pipes
right here
to the front case
as a matter of fact let me show you
exactly the path that it follows
and just you know what we're looking at
this is again the front of the engine
the compressor different compressor
stages
and we get two
right here this is front of the engine
is over there
you have the compressor in in different
stages
compressing the air more and more and
heating it up as you go until you get uh
right here and this is the diffuser
which further compresses the air
before discharging it into the
combustors and then the turbines
and so on but this right here is the
highest
pressure that you have in the engine
and right here this is a 17 stage
of the compressor and right here this
tap
is taking that air highly compressed
very hot air taking that from there
tapping it off and come into this valve
this valve is the anti-eyes control
valve it's controlled by a solenoid
which in turn in turn gets controlled by
it gets triggered
by a switch in the cockpit
flip a switch this comes on valve opens
now
compressor discharge air
comes through and it gets piped through
that manifold
and it gets split and it goes into the
front frame
right here where it goes through the
struts
like here you have the air coming
through the struts
these throats are hollow so now you have
hot air
being pumped through the struts heating
these up preventing the buildup of ice
on these struts from there continues
into the center section
into and it flows out through that port
right here into the
nose dome there's a dome that is not
here now it's missing but there
there's supposed to be one here that
also gets heated by that
anti-ice air but this is a closed
cavity from here
the air gets fed back to the igv's the
inlet
guide veins these are also hollow these
are also heating these are not moving
these are stationary
and in the sense that they're not
rotating with a compressor
they're they're stators they move in the
sense that they change the angle of
attack
but for all intents purposes they're
just as stationary as the struts they
don't rotate
uh so the hot air comes down
from the pipes down the struts to the
center section
down to here and up back through the
igvs
and they get out through the trailing
edge
trailing edge is actually perforated it
has little holes all along the trailing
edge
of the igvs where the hot air exits and
then gets vented back into the
compressor
in the process of that airflow you're
taking hot air
heating up circulating it through the
front frame
through all the struts the nose dome and
heating up
all your inlet guide vanes and then
feeding that back to the compressor
now something that i didn't mention
in this whole piping and which i think
is interesting
and is actually what triggered me to do
this video
is this guy right here this is
a flow control valve
this guy here and this is your
for lack of a better term your your
thermostat that regulates how hot
you're making that front frame
because this valve here
you can't you don't regulate this this
is all or nothing on or off
when you turn it on you can actually
have so much volume of hot air going to
the front frame that you overheat
the front of the engine to prevent that
from happening
we have this guy and the way
that what i find fascinating is that
this is a simple solution
simple in the sense that it's it there's
nothing electronic
very few moving parts it's reliable and
it's effective
and i'm gonna show you how this works
we're gonna take a look inside of
this guy now we're gonna take a look
inside of the flow control
valve which is what regulates the
temperature
of your the front case so you don't
overheat
any components over there and the way
that controls the temperature
is by controlling the flow that it
allows
through the valve the more
hot air you light through the hotter
that end gets if you restrict that
flow you're limiting
how hot it gets the controlling
temperature
by controlling how much flow of hot air
you allow through here
and what i find fascinating is the
simplicity of design
of this valve and the way it works is
i'm gonna explain to you a little so
that you understand
what it is you're looking at in there it
has
a metal coil wound up in this direction
down the center that as it heats up the
hotter it gets
it tries to expand and therefore
rotates the this end of it is fixed
the back end of that coil is attached to
some finger veins that turn
as that metal expands and contracts when
it turns
it blocks off
the path of the airflow
therefore lowering the temperature as it
cools off
it rotates and it opens up again
allowing more flow
and that's dialed to the correct
temperature
for the desired temperature that you
would want in the front of the engine
and this is the inside of that valve
here's the fixed end of that coil
and inside of there that
is that metal coil
and down at the very end that star
pattern that's your flow control valve
those are the fingers that actually
rotate
[Music]
to limit the flow
[Music]
as this coil
as that coil right there heats up
it turns those five fingers in the back
of the valve over there
blocking off the path of the air
no electrical sensors no solenoids no
electronic doodads
all mechanical very few moving parts
robust simple
very ingenious
that's how that flow control valve
works by a simple metal coil that heats
up and
turns those five little fingers to open
up or close
the openings to allow for the flow more
flow or less flow
to regulate the temperature and the
temperature in the front case
of the engine for anti-ice purposes
that is just the way i like it plain
simple
alright you guys next time again
as usual i hope you like
this stuff if you're watching these
videos you do
i hope you find it as fascinating as i
do
um i'll keep putting up videos as i
come across interesting things that i
think you guys might like
uh see you next time if you have any
questions
shoot them in the comments other than
that have a good day
see ya
