Well this was fun. I learned a crapload... will definitely be making more jets in the future (ideally that ACTUALLY work lol). Anybody got any thoughts or ideas i'd LOVE to hear them.

I know I’m pretty late but would changing the fuel possibly create more thrust???

​@jakemakes when are you gonna make another vid

That’s crazy bro! I can’t believe you got it to fire off on the first try! Very impressive 👏

This is really cool, I also like how you put the videos together, your funny to!

Beyond making it efficient, making it last isn’t easy. The engines in the V1 buzz bombs used in WW II only lasted 10 or 15 minutes.

So glad,I've been waiting for this video

I love how your mind works to think of things like this

I have been wanting to do this for ever. You did it for me, Rethink this though. Realize what a ram jet is. Then mate the leaf blower to that. What you end up with is a venturi behind the leaf blower to increase the area of the combustion chamber in relationship to the leaf blower., then add a tapered outlet to increase the pressure. I think it might work.

Yes another great Video

freakin awesome bro.😀

I dont have backyard to try this . Preety cool

You need to run a control test with a much lighter sled. Your thrust isn't overcoming the weight of the sled.

Hey @integza, you are his inspiration!!

Good job boss man

Nice will admit it’s acting a lot like a pulse jet engine sometimes lmao but noice

I too have made rocket fuel. Rocket motors, pulse jets and fan jets. A true jet has a set of compressor blades that compress the air before ignition. You pretty much had a open pipe with a steady ( wide open ) flow of hi velocity air but low compression. What a turbo jet does is after compressor it opens the pipe diameter to slow the velocity but increase the pressure then the actually combustion chamber isnt exposed directly to the air flow but has a flame tube blocking the air, then injector the ignitor surrounded by a tube with various holes drilled along its length to only allow a certain amount of air to combust the fuel spray....if not then it flames out like blowing out a candle . Then after the combustion chamber is roaring away it then expands the air surrounding it and the air fuel it burnt to expel the hot gasses out the exhaust force = mass ÷ acceleration. Before it leaves the exhaust another set of turbine fan type blades that can drive the intake side compressor blades to pull in even more air. The two turbine blade sets are connected in one direction but can freewheel independently in the other like coasting on a bicycle. Then the hot exhaust gasses that still have tremendous kinetic energy are restricted thru a variable sized nozzle but not before hitting the center mounted aero type spike that controls the flame front to guide the hot jet stream out the back without becoming bogged down in the walls of the inside exhaust pipe opening which is the boundary layer. To Increase the thrust on your simple fan jet try to squeeze the sides of the pipe that is before the cc to increase speed then the cc is higher pressure then use a flame tube with exterior pipe with small holes drilled out along it. You will have to do the research on ot but its something like first section of flame tube is 20% the the next 1/3 portion has 30% then the last is 50% of total airflow thru the system or area of the main pipe. As u in rease the air thru leaf blower throttle the flame tube only uses what it needs to be a efficient hot combustor. Wide open would be all the holes area equal the main pipe diameter of jet tube or close to it. That's where the math and design/ testing comes in. The basic principle is easy the hard part is getting it to work efficiently and produce sizable reliable thrust for a prolonged time. Which is way more complicated. Using a car turbo charger one can make a reasonably good turbo jet as it spools up itself ( self excitation) no not that kind- lol) which produces large amounts of rpms airflow and compression. Compression the air is the secrete And exhaust nozzle shape and the combustor and and.etc......

I think to get higher thrust relative to the blower you would have to connect the exhaust to a shaft turning the intake to get more air and so it can spin itself.

Gotta try putting a cone on the exhaust side that restricts it down significantly then opens back up, shaped like a hour glass essentially

This type of engine is actually called a motor-jet

0:40 that's exactly where i learned how jet engines work

Ok hi nice to see you again well that was sweet I was hoping for some hanging meat test to see how it cooked. 😃

Oh funny it didn't even cross my mind to try that XD that woulda been fun

Why not use a complete combustin and water cool it so no after burner is needed.

Have you made a jet engine or have you make a burner for a hot water boiler? Now make a turbo jet engine using a turbocharger (with afterburner for fun).

Could you use a box fan in place of the leaf blower at a distance . Essentially once it’s burning the engine sucks it’s own air in with the fan push some air through . A kind of self feeding engine ?

No bro it is not easy If You would not use of electric motor you might know how hard is to rotate a turbine blade with just air and fuel only You cheat jet turbine physics by constantly running a leaf blower or electric motor But in real jet engine they use motors for just for its starting purposes not constantly Then the engine run automatically I tried for two years and I wasted my 11 and 12 grades by making and understanding this concept
