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!

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]

why? i dont know i just wondered if it was possible.

[Rickthecannuck]

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.

[lemonie]

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...

[rickharris]

:-) (got the recipe?)

[lemonie]

I wish, "The Tesla Sandwich"...

[darkevilapie]

the taste is shockingly good ^^

[r1xlx]

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.

[iceng]

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.

[Mistah Fuzz]

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"

[rickharris]

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?

[10babiscar]

an increase in the efficiency of the jet engine as tesla turbines are more efficient than axial or radial turbines.

[iceng]

A boundary layer turbine ( Tesla ) cannot compress air like a
Jet engine turbine !!!

A

[darkevilapie]

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.

[rickharris]

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.

[iceng]

+2
Correct Boundary Layers are involved !

[Ian01]

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.

[rickharris]

Makes a very poor compressor. Have a search for why it makes a turbine and you will understand why.

[iceng]

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

A

[darkevilapie]

uhm i dont wanna be rude but i wanna pump air not water XD

[squiggy2]

That doesn't matter. All newtonian fluids (gasses and liquids) behave the same, just with slightly tweaked numbers re: viscosity, density etc.

[darkevilapie]

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

[iceng]

First make a successful jet engine then you will understand.

THERE IS NO WAY TO MAKE A TESLA TURBINE INTO A JET ENGINE !!!

[rickharris]

The principle is easy (making one that actually works and produces meaningful thrust may not be)

[steveastrouk]

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.
