i use jet engines like this in a lot of
my projects mostly because i like
extreme and jet engines are pretty
extreme and since i'm using jet engines
in a bunch of upcoming videos i figured
it would only be appropriate to show
everybody what's going on inside of a
jet engine so i'm gonna put together a
see-through jet engine start it up and
film it in slow motion let's go
[Music]
[Applause]
looks like we're about
.005 grams out of balance
[Applause]
i got it almost perfect it's off balance
by one thousandth of a gram on plane one
and two thousands of a gram on plane two
that's good enough for me let's move on
now that i have my rotating assembly
balanced which is one of the most
important parts of putting together any
size jet engine i'm just gonna slide
this in here and i'm gonna go over the
basic operation of this type of jet
engine and what part does what when i
explain how turbo jet engines like this
work to people who are not familiar with
jet engines but are familiar with cars i
always use four stroke as a good example
intake compression combustion and
exhaust all in one continuous cycle but
since you have all these happening in a
linear continuous fashion that makes
this a brighton cycle a brighton cycle
is simply compression combustion
expansion equals volume overall the way
these jet engines work is pretty simple
the air enters the intake here
gets compressed by the compressor that
compressed air moves through the stator
into the combustor where it gets mixed
with fuel gets ignited creating heat and
expanding gases which come out the back
of the engine push the turbine wheel
powering the compressor to complete the
cycle as well as producing thrust now
that you have a better idea for how
these jet engines work i'm going to
finish putting this together
[Music]
[Music]
so
[Music]
so
[Music]
[Music]
i'm all done building my see-through jet
engine and it came out really good it's
nice and transparent solid feels strong
and it needs to be to handle all that
compression heat and power without
further ado let me get it mounted start
it up and see what it looks like inside
of this jet engine while it's running
all right here we go let's see what
happens i'm a little bit nervous but i
think it's gonna work
[Applause]
so
[Music]
all right here we go
[Music]
oh that's hot oh yeah that case is
burning hot wow that really worked out
well and it really gives you an idea how
much pressure is in the cold side of
that engine because it blew out my
silicone gasket
and uh yeah that had quite a bit of
pressure on it and to give you an idea
how much air is actually moving through
one of these engines you can see
the stains from the flow
of the air that's how much air actually
moves through these
i don't know how many cfm this is
actually it's measured in pounds per
minute i'm glad to say that that went
really really well i do want to do one
more experiment before finishing this
video i'm going to hook up the fog
machine start the engine one more time
and pump some fog into the front of the
machine right here and see if we can
actually see the air flow going into the
engine and maybe the airflow inside of
the engine i'm not really sure but it's
worth a shot oops i accidentally left
the fog machine on
and closed the door
i'm feeling pretty confident
[Music]
[Music]
all right here we go
[Music]
all right so the flow characteristics
weren't as cool as i thought they were
going to be i thought we were going to
see a lot more but that does prove my
point and that does give you the idea
that these type of jet engines or jet
engines in general don't really pull in
that much volume of air for the amount
of thrust that they produce a lot of
people think like if it's 80 pounds of
thrust it pulls in 70 pounds of air
that's not the case most of the energy
comes from the fuel that's the entire
idea behind jet engines i was really
surprised that this whole thing survived
but overall that looked pretty cool i've
always wondered what was going on behind
that cover when these engines were
running especially when i did that jet
powered tesla just to imagine kind of
what was going on inside and to be able
to see it that was definitely pretty
cool i was surprised that this whole
thing worked and didn't blow apart but
it worked so that's about it
the see-through jet engine was a success
and this is part one i'm gonna do a
follow-up you know think of some
creative idea to kind of see inside of
that combustor i really want to see how
that glow plug is working and how the
starting mechanism works and all that
other stuff and let me know if you're
interested in that too and i'll come
back with a part two of this i have
something really creative in mind but
other than that i thought this thing was
going to blow up for sure i was like
this is one of the first projects i did
where i was trying to like throttle it
up and i'm like uh should i go all the
way i was like sweating under the
armpits with this thing so but it worked
it was successful tell me what you think
in the comments below don't forget
tell me what you think in the comments
below don't forget to subscribe and uh
yeah see in the next video
