Dude you just had a bad teacher. Im from the US and my engineering teacher is letting us build a turbojet engine. or at last approved it and is helping us design it.

Figured out how to find the drill bit size!! It's the square root of (each hole area/pi)x2 For example, √(.22×3.1416) = .26 .26 × 2 = .52cm bit.

i'm in the fortunate position of being good at both those subjects and understanding them with relative ease but I can see quite easily how the teaching can be improved, just with colin explaining things makes it all so much more interesting and enjoyable. I think one of the easiest ways to teach is to simply make such the students enjoy the teaching, then learning will come naturally

Get yourself this book: "Mechanics and Thermodynamics of Propulsion". It's 700 pages, 400 of which are for turbo jets. The why is very complicated and not really possible to convey in a short video, and his math makes a lot of assumptions that aren't necessarily true, but close enough.

Area is easier to calculate if you leave Pi out of it, since the drill holes are also circular. Take diameter of drill bit (say 5mm) and diameter of intake (say 50mm). Then number of holes is given by 50*50/(5*5) * percentage/100 = percentage. For a 10mm drill bit it would be 50*50/(10*10) * percentage/100 = 0.25*percentage.

You should probably be the next top gear host (oh and square root of area divided by pi lol).

I should do this as a project for my tech design or manufacturing class next year. Now that I'm listening to the math it's really simple.

Came here after looking at new video, amazing how its grown over the years

These older colinfurze videos give me some degree of pleasure, but I'd almost kill for Colin to provide one or two videos taking on things at an 'Ave' or 'This Old Tony', or even 'BigClive' level. Based on their numbers of subscribers, many people are interested in that sort of video. Comparing the numbers of subscribers, they are few-and-far-between. However, if Colin had any interest in helping people like himself (the at-home makers/machinists), rather than those who paid out the big bucks for the clicks, it'd be so fucking awesome of him. Colin has some of the coolest shit ever! I just want to know more! Especially in more recent videos---he's completely given up any bit of a show-and-tell mentality with those. It's purely "show." (Perhaps have a Patreon account, in which contributors see nothing except the details of construction. Details and editing not necessary. Just video the process! I guarantee he'd get many thousands of subscribers, each putting $5+ in his pocket each month!) @colinfurze If you're listening, we want this. It's very nearly free money! Please let us see the cool shit that goes into these things. (Yes, this is 5 years old. I know this. If no response, I'll send it more privately.) Anyway, keep it up. And do more close-ups!

Hi, how you achive a good axis lubrication?

Best. Math. Teacher. Ever

Love this project,i,m gathering all the bits to build one,do you think it would matter if the outside of the combustion chamber were about 170mm bigger than the inside ?

Just a quick question to anyone who's having experience with these homemade turbojets - How important is it to have the combustion chamber completely air sealed? I guess the more it is, the easier it will be for it to start and run, but how "whiny" are they in general? I am not a good welder by any means... the welds are not very smooth and it has some air leakage here and there(I will fix this when I can) also what is the recommended fuel pressure for startup? I have some sort of pressure regulator that only will let out 30mbar max. Do I need more pressure than that? Any answer will be greatly appreciated!

@willday1558

8 жыл бұрын

+IAA015 It'll probably be harder to start if there's leaks in the combustion chamber, and also might be a fire hazard, so look over all your welds and make sure you can't see any daylight through them. If you do, just weld a solid tack on the pinhole and grind it flush. Most people who run these have no regulator, the propane comes straight from the bottle, so when you plumb up the fuel system, make sure it can withstand the pressure, and any rubber hoses should be far from the engine so they don't melt and spray propane everywhere.

Yes that's me. Still doing the BMX parts etc. Been stalking your channel since the wall of death stuff.. Saw your Redbull entry the other day and it reminded me to see what you are up to. Shame that they toned down the final jump soon after your run. Do you know what your actual time was compared to others? Must have been up there.

You sir, are an absolute legend!

what can I say? Your funny, wild, smart, and I think everypone will agree with me when I say you know what we want to see :)

Awesome! I can't wait to see it in action ^_^

Does the size of the turbo matter so long as you stick with your recommended proportions? I’m considering doing this many years in the future with a massive turbo from an old diesel locomotive.

Wouldn’t it be sooo co, but to see all the engines working in a row would be brilliant!ol to have a meeting of all those that copied and have built your design or even better made there own? Unfortunately I have no engineering shop so can’t build anything , but how cool would it be to have every machine come together, just like your hip movements, and maybe you would have enough power to reach the moon? Take care, love what you do, was good at Maths but forgotten more than I learned LOL

if i had a nickle for every time i thought you would be one hell of a professor, well, i'd have a lot of nickles.

the transitions are 10/10

I think your E in maths was due to bad teachers not keeping you interested as you are obviously wicked smart. Love your videos!

Love this; however, I am just wondering the amount of thrust this would produce and if it would be big enough to place this into a small car. I have been wanting to do a car rebuild but I am wanting to convert the trunk into the motor compartment with a sound proofing and heat shield. I am wanting to see if I can put something like this into a Toyota Corolla that I would run on a 25 pound to 100 pounds of propane. However, I am needing to figure out if I can place the propane tank and the motor in the same compartment or if I would need to remove the gas tank and place a protective housing around it under the car. I am heading to Costa Rica and I would like to do this build there where the cost of supplies will be a lot cheaper.

Best teacher ever 😂😂😂

This video is both nutty and educating i should say! XD

awesome, dude. you should create some sort of wing and mount one of your jet engines, and make it fly to the first building and burn it down. rogallo wing should do. anyway thats cool! i also made crackshaft while watching you'r video. and it will be damn good crackshaft.

You lost me at 3:00 lol Love your videos

I'm trying to design my own turbo engine, and I'm struggling to figure out the size of the combustion chamber. I think the ratio provided is great, however, do you mind explaining the physics to that? (why is the diameter of the combustion chamber have to be twice the diameter of the inlet, and why does the length have to be 6x the diameter of the inlet?) These numbers are quite important, and I thank you for posting them. I just like to understand more, but so far, I have no idea where to get these info. thx!

Where did you get your maths information? Did you have a reference for these dimension estimations? Surely it wasn't trial and error. Thanks for the help!

Can you use this for axial flow turbines too?

this isn't exactly a DIY project, though Colin makes it seem easy

In 1928, RAF College Cranwell cadet [5] Frank Whittle formally submitted his ideas for a turbo-jet to his superiors....... In 1935 Hans von Ohain started work on a similar design in Germany, initially unaware of Whittle's work

colinfurze- maybe try to do an instruction on adding an "after burner" tube? I'd love to see that...

Looking forward to seeing it run. Interesting that your soap box racers BMX forks from "the scrap yard" had canti mounts with the sneaky (and hard to drill) cable routing, and you had a radial 95 spoke wheel fromt he 90's :-) Dont be ashamed of your BMX roots...

This guy is awesome and really smart

Looking forward to seeing what you power with it

haha its in tomorrows geek week videos

Makes me feel so much better he got an E in maths and still does this stuff

Hey Colin what welder do you use thanks

what a fantastic name for german telephone pranks!!!!

Would there be a noticeable drop in efficiency if you made the primary holes 20% larger?

Building my own right now. what is the location, or how do i find out the location of the primary holes? how important is this location?

So when does the Turbo Jettle start to materialize :P , Your my kinda nuts Colin keep it up son !!

what did you do about an oil feed for the bearings mr furze?

put a shaft on the intake nut and run a disc with magnets and copper coils. Also how about putting the whole thing in a a cone shaped ram jet and use the heat to create more thrust.

Colin how are you going to keep a constant oil feed to the turbo?

I might build one just wondering where do u get all your info to make this ?

Fair enough, it's an interesting video either way. I look forward to the results...

If your turbo is less than 45mm inlet and you the flame tube 3x the diameter, do you then use this new dimension when choosing the length too, or the original turbo diameter? Eg my turbo is 40mm so the flame tube is 120mm but should it be 40mm x 6 long or 120mm x 6 long?

This swoopey bit is my favourite

The calculations for area of the holes does not account for the curvature of the surface that the holes are in, if you flattened the tube the holes would become elliptical and have a slightly larger area than a round hole. It works though so it is close enough.
