could you use an tesla turbine to make an jet engine?

i was looking around the webs, and i found that there was no information about an Tesla turbine-jet engine. i was wondering if a Tesla jet engine is possible. so i looked up jet engines and tried to figure out how they work, but i still dont know if it work. so i thought i would ask some smart peeps who would know the answer.
also i did see a guy who made an pulse jet engine with an Tesla turbine on it but thats not the same as a jet engine. but it did gave me a few ideas(see picture made in solidworks by me (yes its not very pretty, made it in like 30 sec)) i thought of an Tesla jet engine but i dont really think it can work. plz give feed back and help me in my quest for jet Tesla engines.
this jet engine sucks up air with the big Tesla turbine and adds fuel to the air  then burning it causing it to expand forcing it true the second Tesla turbine which powers the first thus the cycle is complete i guess.
A = air inlet (yes i know the turbine in front is bigger then the turbine in the back idk why i did that XD )
B1&2 are the drive shafts you could connect b2 to b1, or b1 to extra fans or props to make a jet prop engine ¿? (XD)
c is fuel inlet, i dont know how this should work

As shown in your drawing, B1 is a Tesla Pump or Compressor. B2 is a Tesla Turbine.

Pump B1 needs power at shaft B1 in order to operate. Turbine B2 runs on fuel and rotates shaft B2. By hooking up shaft B2 to shaft B1 with pulleys and a belt, then Turbine B2 drives Compressor B1.

Then you will have suction at the Compressor inlets A, and outlet thrust from the Turbine B2 exhaust.

Tesla compressors can be staged to produce additional inlet pressure for staged Tesla turbines.

However, Tesla turbines and compressors were not designed as jet engines for propulsion or to develop thrust.

The Tesla turbine does develop shaft horsepower at high rpms quite well, and the Tesla pump can be used to compress gasses or move high solids liquids.

Nikola Tesla said his Tesla disc turbine was "the greatest of all my inventions".
He designed it to power his electric flying machine, which had no wings, ailerons, or propellor...
Not everyone knows about homopolar machines.
I am a fan of Tesla (saw and agree with your life's mission web site )
and would Greatly appreciate concrete information on Tesla's
electric flying machine.

Tesla stated that his flying machine was "the dream of my life" (interview, New York Herald Tribune Oct 15, 1911)

He developed his Tesla Turbine (which he called "the greatest of all my inventions" in his autobiography) as an electrical generator for his flying machine. He mentioned a twin counter-rotating 200 horsepower Tesla turbines with AC generators.

"It was in seeking the means of making the perfect flying machine that I developed this engine."

"...my airship will have neither gas bag, wings nor
propellers."

"You might see it on the ground and you would never guess that it was a flying machine. Yet it will be able to move at will through the air in any direction with perfect safety, at higher speeds than have yet been
reached, regardless of weather..."
(New York Herald Tribune interview Oct 15, 1911)

There is a Yahoo Group dedicated to the discussion of Tesla's Flying Machine. It's archives have interesting papers, and Bill Lyne :
http://tech.groups.yahoo.com/group/teslasflyingmachine/

Here is a PESWiki page dedicated to it. http://peswiki.com/index.php/Tesla's_Flying_Machine

Tesla's Flying Machine is discussed in Bill Lynne's book "Occult Ether Physics: Tesla's Hidden Space Propulsion System and the Conspiracy to Conceal It",

Those links should get you started... 
Questions or comments would be fun to discuss!

To get a jet to work you compress air - add fuel and burn it.

A tesla turbine is driven by the air it does not significantly compress it.

So I guess NO is the answer.

What do you think the advantage might be anyway?

Umm, not not sure how many people here are talking rocket science and how many are talking about somethine else, but a turbine doesn't compress air, that's what compressors do. a turbine powers, normally the compressor and sometimes additional features like a prop.

Do you mean that when you run a Tesla turbine in reverse (as a pump) it doesn't generate enough pressure for a jet engine? I don't know any numbers for these things but I'd assume that since it's more efficient than an axial turbine it would also be more efficient as a pump/compressor.

The Tesla turbine will make a very poor ineffective water pump ( no flaps )
You need a compression air bladed pump for a jet.

uhm i dont wanna be rude but i wanna pump air not water XD
That doesn't matter. All newtonian fluids (gasses and liquids) behave the same, just with slightly tweaked numbers re: viscosity, density etc.
Makes a very poor compressor. Have a search for why it makes a turbine and you will understand why.
an increase in the efficiency of the jet engine as tesla turbines are more efficient than axial or radial turbines.
A boundary layer turbine ( Tesla ) cannot compress air like a
Jet engine turbine !!!

darkevilapie (author)  rickharris6 years ago
ill think about the compressing problem,
the advantage is that a tesla turbine is simple to build and is capable of super high speeds and has a higher efficiency than normal bladed turbines.
You need to look up WHY the Tesela Turbine works - Driving it would be different to blowing high speed air across it. your not going to get a simple reversal of the actions as you might if it had vanes or fins.

Correct Boundary Layers are involved !

Just hypothetically, without doing the math, wouldn't it be more simple to try and work it out to incorporate it into a 9 stage intake system So a center jet engine, the surrounding 8 have 4 outflow compressor and combustion and 4 compressor and expansion system then have feed into exhaust like a super-booster afterburner. So the intake would split into 9 separate engine systems, the center would have to use conventional system with the turbine to feed its own compression and intake system, then have the 4 intakes feed into compression and then try something extreme like fueling in cryogenic, like from a LOX tank for expansion and then offset to push into turbines offset onto the side of the engine under the main haul and have those turbines feed the intake from those 4 and the other 4 which would have compression and then combustion and feed into center shaft after combustion and turbine because the turbines would definitely not be able to take that kind of centigrade, because cooling at that stage would destroy the whole purpose of what this would be to try and accomplish, and the then have that force center of exhaust and the Tesla turbines exhaust would feed the mixed with LO and compressed air mix to beginning stage of exhaust, but then would need to redirect the cool air from the standard turbine that normally sits directly, so then the exhaust system wouldn't destroy itself but redirect compressed air into the Tesla turbine (that you wanted incorporated, could then add additional nitrous or hydrogen, but then again, that much cryogenic elements, and redirection of flow for the sake of greater afterburner seems good and all, which I would love to see build and could probably design it quite well would feel like a lot of wasted effort since 80%+ of the actual force derived from a jet's engine comes from the turbine, but then again, in theory this could probably allow for one to finally crush mach 6, so good all in all, and you could have a vehicle without without a prop, wings, or gas bags, like the us gov's surf which is some pretty epic machinery, but what would this accomplish? But then again, working out the material, specifics, how to make a Tesla turbine (which buddy is quite finicky and I can't think of one which could even handle 200 lbs of pressure safely so that would need a lot of innovation, and I'm never one to say can't or impossible, but yikes it could be rough times bud. (also, having them inline under the haul with that much incoming force would allow for it to have some torque and not just raw hp so that could be a good concept)

The last thing I would want to say, is if you're looking to actually make such a concept a reality, you definitely going to have to get creative and not stick to the confines of regurgitated and diluted information you had stuffed down your through during your past schooling and actually think.

So I'm not sure if this is what kind of response you were looking for but hope it helps down your path.

I googled the exact title of this debate, so i guess you could say i fell for the Tesla buzz.

I do have sort of an excuse thou. I wanted to fiddle with model RC jet engines. Basically i can get to a decent lathe and manufacturing a tesla turbine is somewhat easier than axial turbine.

My idea was a little different and less tesla fanboy ish. I basically wanted to put a fan in front of the the tesla turbine, mounted on the same axle, then add fuel directly in between the tesla discs and have the combustion in there and possibly have a secondary fan after the tesla to keep it all running if the tesla itself wont do the job.

Im unsure about the combustion inside the tesla, I assumed it would generate more air inside the tesla and somewhat drive the engine, at the very least it will be a decent fuel/air mixture. But then again if the secondary fan is needed, im not getting much effect for my tesla turbine,

lemonie6 years ago

Why? I'd be interested to know where this idea came from.

Are you one of these people who think that the world's been overlooking old technology, like no one else has ever thought of something like this in the last ~100 years?

darkevilapie (author)  lemonie6 years ago
why? i dont know i just wondered if it was possible.
Real simple... tresla turbine is the most efficient air mover in existence. A jet engine is compressed air ignited and pushing a turbine to compress yet more air. Take your idea and place both turbines on the same shaft with a burn box in between. Like the DIY jet engine made from an automotive turbocharger. To improve, add another compressor to the sequence by piping the exhaust to the intake etc and you get multiple compression stages. Similarilly, add a scavenger turbine(s) to the exhaust. Trick is to have them all on the same shaft. My idea was to add yet another wheel with magnets in the discs and generate a lot of electricity to electrolyse water and make hydrogen gas to burn. Tesla had the magnetic geometry worked out so that the magnetic generation actually assisted the spin but I can't find that drawing.

Tesla and Coanda lived in the age of enlightenment... we are just crawling out of the dark ages to realize the signifigance of their inventions. The other trick to a tesla turbine is to follow his design exactly...MIT did this and finally achieved the 97% efficiency he claimed.

Good luck with your build.
In defence of the idea of re visiting old technologies, There are some ideas that were thought out in the 1800's and didn't work because of lack of suitable materials. Modern material science can overcome the problems in some cases.

Example the use of rotating cylinders as sails for a ship.

Vertical axis turbines?
Yes, I am wary of anything that has "Tesla" mentioned in it, as people often over rate the technology beyond it's actual practical value, just on his name.
Maybe in the back of a notebook he jotted down how to make a nice ham-sandwich - it doesn't make it the best buttie ever...

:-) (got the recipe?)

I wish, "The Tesla Sandwich"...

the taste is shockingly good ^^

the reason Teslas don't work well under load is that the boundary layer drag is insufficient which is why Tesla advocated adding flat bits to the plates and thereby convert the thing to a basic impulse turbine like a waterwheel.
It shoudl be possible to up the efficiency of Teslas by making the air itself act as the bits.
I also think that the outer edges of the discs should have some scooping design in order to ensure the air actually does spiral round and exit via the centre holes.

I do think though that if the idea is to make a turbine with very high efficiency ad torque at low speeds then the JetWheel is the way forward as te JetWheel design takes the full rpessure of entering air or steam and uses it once and then gets an additional push from it and also the air adds to the used air to give very high efficiency.

If you exhaust the Tesla turbine through a hollow shaft, a radial flow jet engine makes sense. Put a Tesla pump (this time with the hollow shaft as an intake) in front of the turbine, connect the shafts (mechanical, no airflow between) and put the combustor in the output from the pump. Feed the hot gas into the nozzle of the turbine. For a turboprop, just extend the intake/shaft and gear it to the prop.

Tesla was only interested in generating AC electricity, Not jet Thrust !
Tesla was embroiled with Thomas Edison the proponent of DC,
after a bad first acquaintance.

Well what if you turned it into a generator instead of an actual jet engine? throw a small magnet on there and ramp it up to 100,000 rpms, and generate some juice, take advantage of "The Most efficient Engine Ever"

thanks to you all for awnsering my question :)
i am very glad to see that people are interested!

First make a successful jet engine then you will understand.

THERE IS NO WAY TO MAKE A TESLA TURBINE INTO A JET ENGINE !!!
The principle is easy (making one that actually works and produces meaningful thrust may not be)
The efficiency of a Tesla turbine falls quite a bit on load, and its efficiency drops below that of an axial flow turbine. They are also very tricky to build for hot working, since they have small clearances.
