Whey hey! So then, we've made a Jet Bicycle, we've made a Jettle! Now these are all pulsejets,
there is another jet engine which we can make. If we take the turbo from a car, we can make
it like a proper jet engine that sounds like an aeroplane .
Let's make this easy, let's make it simple, let's make it cheap! Which means scrapyard!
So got a load of tubes, let's start cutting them up, and I'll go through all the measurements
and stuff after I've made it, because it doesn't make any sense unless I've got something to
hold.
So here we've got our combustion chamber, then before I weld all this up, I've kind
of, put like this little collar thing around the side there, so when that bit flame tube
slips in, it's perfectly central and also I can get this bit sat on their, butts up
to it nicely, before I weld this on there so the whole thing's not skew wiff or anything
like that. Then when it's all done, it'll be awesome!
Oh I love drilling holes... especially 5mm ones! Hmmm Just another 27 to go!
Flame tube!
Oh what a fit!
Look at that... smooth
That's good! yeah! Combustion chambers done, it's all like that, wonderful bit of engineering
there! And then a flame tube is all done. Now I've put spark plug in the end here and
all also a little fuel rail in the end,
which is just a bit of pipe with holes drilled in it. It's adjustable at the moment
so you can get it in right, and then once it's finished, probably just weld it in. Don't
forget I'm gonna do it maths video after this, so you know how big all these things are supposed
to be. Let's get all this fix in, get it fixed on the turbo. There's one more bit of tube
to do.
woohoo look at this!
Anyway before I get too excited, one last pipe gonna connect them into here. So there's
a bit of tweaking to do, and it wants to shift in just off-center. So it kind of like, if
you can imagine like a mr. whippy effect, as soon as the air comes in, it goes around
the outside, gets sucked in the middle, bang, bang, bang!
Yes! The moment of truth!
Whey! it's finished, we've made a jet engine! Ok next video, we'll go through all the maths
so you'll know how
big all the diameter's, lengths need to be etc! its actually very simple! (blows raspberry!)
