Wow! What an amazing piece of engineering marvel. A micro engine that can produce a very high flow rate of thrust. Actually while seeing this, it reminds me of the movie The Rocketeer (1991) where in people can go to places using their jet-pack backpack. Perhaps the idea will eventually be seen in the near future.
Immaculate. Not an engineer, but wish I went to school for one... House bill, car bill, married, prob too late... Keep posting these things, this is a an amazing piece of machinery.
Possibly the most expensive and insane method of charging a Jaguar battery, are they serious? Getting an Axial flow Turbine to run at this size?...a bloody miracle.
am impress with this micro engine. As a kid jet engines always fascinated me and now there one that i can play with and test all on my own.. NICE look forward owning one.
Certainly a marvel of Engineering. My experience indicates that the most demanding is the diffuser and the final power turbine. The slowing of the air into the burner and the bypass air to cool everything down not to lose the metal structure. With five axial compressors I would say that the compression ratio is 5:1, not high enough for an efficient engine, but the workmanship is brilliant. Congratulations.
Well, you certainly have far more expertise than I do, so I'll take your word for it. I wish someone could come up with something more efficient than the piston engine though.
At 100 lbs thrust it's more powerful than any single RC jet engine. JetCat's P200 is rated at 50 lbs. I wonder what the weight of the engine is as well as exhaust temperature. Perhaps JetCat is working on a similar idea for JetMan. He currently uses 4 JetCat P200's.
I had a similar thought in the past few years: Electric drive, ideally hub motors, with a microturbine generator, and ultracapacitor bank to provide on-demand power. No expensive batteries (just expensive everything else :P)
As a way to recharge your batteries to get you home I love it. It runs on anything, and will stop people from being scared to own an electric vehicle. Best of all, if you wanted to, you could recharge your batteries and just roll from the thrust alone, to conserve even more power. Who hasn't wanted a car that can sound like the Bat Mobile at some point, LOL. Seriously though, if you know how far your electric goes on a charge you may never need this, but it's always good to have a backup.
What's the power delivered (excepted the 100lbs thrust)? Converted in Watts how much does it give? What is the power on the main rotor? A very nice work (but a very noisy one lol)
Honeyell makes apu's that utilaze the blisk technology but they are not that small. I was production engineer for the axialflow line. This technology works wellwhen applied in the correct application. It looks like you are on the right track dont give up.
cnsidering you only need to run it to charge a battery ... and that would be done in 30 minutes .... not really ... and if you put it in a muffler it could be quieter than anything on the street BUT an electric ONLY car ... all for the a basic jerry can of fuel instead of a large tank hold 50 gallons .
Everyone here is missing the point. The unique feature of the Bladon gas turbine is that it has a multi-stage axial compressor instead of the centrifugal compressor common to all other miniature gas turbines so far. Engineers have dismissed axial compressors in miniature turbines as impossible/too difficult/expensive. A multi-stage axial compressor gives better pressure ratio and thus more power, or lower fuel consumption for the same power. The secret is in super-accurate machining.
I asked a few questions sometime last year about the Bladon turbines, and the companies response was pretty much that due to the use of the air bearings, they haven't intended nor tested these engines for RC aircraft use. their main purpose is to use them for static, automobile or house energy production. it would truly be a shame if they did not enter the RC market though, these Axial flow engines are way more efficient and powerful than the alternatives currently.
godd point. hehe but seriously. i have a diesel heater in my toyota yaris,, the fan dont run as fast as this jet, but is extreamly loud IF YOU REMOVE THE EXAUST HOSE and mufflers.
I can't help wondering how those discs work in the long run. Will the blades start to ring and fly apart, since they don't fit loose as they do in full size engines.
Brilliant piece of engineering, the best thing ive seen on RUclips in a long while. Id be interested in its lubrication system, i dont see any oil lines or oil tank/pump anywhere
OK. Now I want to build a mini-turbine jet engine of my own. I would like to know how they are controlling and regulating the flow of fuel to the combustion chamber. Also, I didn't see an After-Burner can on the thing just a fixed cone discharge nozzle. Any thoughts on the After-Burner idea? I have done worked on a Jet-Car running a single Lear-Jet axial-type turbine jet with an extra can attached to the rear of the turbine, minus the nozzle, but with 4 additional fuel injectors and an igniter
Turbines may "hog" the fuel, but you must admit they do have a much better power to weight ratio than diesels. Example: Wärtsilä-Sulzer RTA96-C, weight > 2300 tonnes, power circa 80Mw, SFC 171g / Kilowatt-hour (used on the Emma Maersk) VS 3 LM2500 industrial gas turbines: weight 4.672 tonnes each (total 14.016 tonnes), power 25-35Mw each (total 75-105Mw depending on version), SFC (converted from english units) 226.9g / Kilowatt-hour (engine is a derivative of the CF6 as used on the Boeing 747)
This is incredible but I'm still holding out for the day someone TRULY goes all out and builds a miniature twin-spool turbofan, say 10 stage axial compressor and 2 stage axial turbine with the option for an afterburner. This is a huge step in the right direction. Heck I'd be impressed with any twin-spool micro jet really...
Could you share the plans with me? I have bought a titanium disc that can be made to 2 fans (turbine blades). I intend to buy more to make 4 or 5 blades. The size of one disc is 128 mm x 40 mm thick.
A five stage axial compressor in this size is an amazing achievement. With that in mind, 100 lbs of thrust was no less astonishing. I'm still puzzled, though, despite reading all of the comments and replies. Two preliminary questions, with points I'd like to raise, please: (1) - How will thrust be converted into shaft horsepower, in order to drive a rotating generator or alternator for battery charging in (to use the example in the video) an electric car? What is shown here is an engine producing thrust, which is of no direct use in such a role. It needs an additional shaft and gearbox and perhaps further turbine stage(s). (2) - Would a centrifugal compressor section consisting of one or more stages not result in a far more fuel efficient, robust and cheaper engine, with perhaps an easier and more compact power take-off arrangement? The engine diameter would doubtless increase, but length should decrease, all of the previously mentioned influences considered. BTW, I'd have been more comfortable watching the video if the chap in blue hadn't been standing directly in the firing line if any rotating parts had decided to fail structurally. Have casing containment tests been conducted? I cringed even more when they started looking into the jet pipe from behind.
Problem is transmission of power ie. gearbox. You could couple this to a conventional turbo shaft "transmission" with some engineering and a 5-axis CNC machine. The problem with very small turbines is their lack of torque range meaning you have to run it at 100% rpm to get any useful power out of it. This turbine was meant to drive a generator that would power electric motors and store the surplus electricity in batteries making it real efficient.
Beautiful piece of engineering. I thought the Reynolds numbers were the reason why miniature axial flow compressors wouldn't work, now I know better. Considering the added complexity and expenditure, is this axial flow jet engine that much more efficient than a centrifugal flow jet engine? Also, in respect to using this as a battery charging power unit, wouldn't a miniature turbo charged diesel engine be much more efficient?
Forgive me for being confused, but are not turbines and just basically the same? I see a turbine as extracting energy through rotational torque whereas a jet the energy is extracted through the thrust of the exhaust. So which is this engine. It. To me it appeared to be for rotational energy until you took it outside then maybe for thrust but only a weak maybe on the thrust thing.
How much will one of these cost you? I can see using this for almost everything! A generator, for travel and so on. If there is a modular system of devices from a car, bike, generator and whatever else this can be used for. You can just take it out of one device and drop it into another device. Being so small compact and light. it's the perfect device in a survival situation. But you have to have all those things built already. When you need to use a device you just drop the jet into a already build modular system. It would be awesome to see something like that. I am sure as time goes on this tech will become cheaper and more efficient to do it.
A lot of dumb comments from non engineers about this engine. If they really understood what they were looking at, they would not make such stupid comments. Its an Axial flow micro turbine, a miracle it runs at all at this size due to its compressor stage inefficiency. Please stop making stupid, lame comments about things you dont even begin to understand, instead, go read up on it. Come back in a weeks time (thats how long it will take to do your research), and even then, you wont be qualified to make comments about this remarkable feat of engineering excellence, ok?
***** The compressor stages are innefficient due to reynold numbers. The compressor stages are like full size engines, ie Axial. Whilst it works well on a full size engine, it does not scale down with the same degree of efficiency on a tiny model engine like this one...Not that this is a badly designed or made engine...just the basic laws of physics..Told you it was a complex subject didnt I?
great to use for heat /generation as well and combining it with compact 100 kw gen./motors not only for automotive but for home energy supply with locally produced fuels.CIAO GIO .
Turbines are actually very fuel efficient, its just that the usable energy is not easily harnessed by any application where start and stop motion is desired. Turbines don't idle up and down quickly, and use roughly 2/3 the fuel at idle as it does at full throttle. However, as far as efficiency, jet turbines can be up to 80% or higher vs. their piston styled counterparts that can acheve 40% efficiency at the high end. When used to generate electricity, a jet turbine can be way more efficient.
I would be interested to know its fuel consumption compared to a Centrifugal compressor engine of the same output...other than that, very impressive. Bet its pricey though....guess it runs at lower rpms for any given amount of power output..compared to the centrifugal type?
The RC world would Love to get there hands on those!
crazzylee yes quite and their hands are free because no wire coat hangers
Wow! What an amazing piece of engineering marvel. A micro engine that can produce a very high flow rate of thrust.

nicely built engine ,,amazing how things look when someone puts the effort into their products.. good job.
Possibly the most expensive and insane method of charging a Jaguar battery, are they serious? Getting an Axial flow Turbine to run at this size?...a bloody miracle.

Congratulations.
Excellent engineering AND manufacturing technology. Wish it would say more about the weight and thrust.
Sounds like a miniature J-79 turbojet. Good show mate
one of the most impressing items I have ever seen on here or anywhere!
Well, you certainly have far more expertise than I do, so I'll take your word for it. I wish someone could come up with something more efficient than the piston engine though.
One of the best designs for jet engine
that thing is sick! and he said they can make them even smaller! wow
How get the plan?

Bloody outstanding Blitish invention 👍🏻

awesome design, when is it likely to be a productive item and truly a viable option for small vehicles.

What's the power delivered (excepted the 100lbs thrust)? Converted in Watts how much does it give? What is the power on the main rotor? A very nice work (but a very noisy one lol)
so it produces 100 pounds of static thrust how much hp and torque would it make if you put a pto on it?
sputtering performance means rotating stall problem which can lead to surge then flame-out. no wonder jaguar backed out.
how big would you need to make 1 or 2 to lift 10stone into a hover or a small flight?
How much thrust does that put out? Or have they ruined it by making it into purely a generator?
Two of these would lift me straight up.
Bet these will be a hot salvage item,down the road.
Honeyell makes apu's that utilaze the blisk technology but they are not that small. I was production engineer for the axialflow line. This technology works wellwhen applied in the correct application. It looks like you are on the right track dont give up.
Well I guess it also solves the problem of finding a sound for electric motors so people can hear them coming.
cnsidering you only need to run it to charge a battery ... and that would be done in 30 minutes .... not really ... and if you put it in a muffler it could be quieter than anything on the street BUT an electric ONLY car ... all for the a basic jerry can of fuel instead of a large tank hold 50 gallons .
Hearing protection is for whimps!
What did you use to take the footage of that thing? A potato?
2011..? Yeah, probably. An expensive one.
Camera tech has come a looong way in a very short time.
CyberiusT I'm thinking Russet. Yeah, definitely a Russet potato.
RDELAPLAZA Hahahahahaha funniest thing ive heard in a long time hahahaha
Congratulations. It is your potato joke, among tens of others, triggered my realization potatoes have eyes. I'm certain it was your flawless delivery.
LOL
But what's the cost of the engine when mass produced?
$ 59.95 at Walmart,,,,,, hehehehe
Well start it up i have seen this post for 2-3 years now show us how smart you are !
Jags are actually built very well these days. The days of British Leyland and "that'll do" mentality are over.
Interesting comment from the usa.
Quite inspiring
And down in the workshop I go.....
thats amazing!! sure this jet took so much calculations!
do u think it could work on HHO Gas
and what is the prosneige of efficiency

The testbed is adorable.
No hearing protection, no fire-bottle and someone loitering directly in the plane of rotation.
"YES, PURRS LIKE A KITTEN, RUNS QUIET DOESN'T SHE!"
"MY NAMES NOT BESS, PAUSE FOR A MITTEN?, SORRY I CAN'T HEAR YOU!"
Seems entirely practical :P
godd point. hehe but seriously. i have a diesel heater in my toyota yaris,, the fan dont run as fast as this jet, but is extreamly loud IF YOU REMOVE THE EXAUST HOSE and mufflers.
I can't help wondering how those discs work in the long run. Will the blades start to ring and fly apart, since they don't fit loose as they do in full size engines.
Are the stators variable or fixed? What is its compression ratio? Have they put a power turbine on it? I want to know more!
Thank you for this piece of engineering. I would like to buy one of this engines, where should I?
Brilliant piece of engineering, the best thing ive seen on RUclips in a long while. Id be interested in its lubrication system, i dont see any oil lines or oil tank/pump anywhere
They add turbine oil to the fuel at around a 1 to 20 ratio
OK. Now I want to build a mini-turbine jet engine of my own. I would like to know how they are controlling and regulating the flow of fuel to the combustion chamber. Also, I didn't see an After-Burner can on the thing just a fixed cone discharge nozzle. Any thoughts on the After-Burner idea?
I have done worked on a Jet-Car running a single Lear-Jet axial-type turbine jet with an extra can attached to the rear of the turbine, minus the nozzle, but with 4 additional fuel injectors and an igniter
Does this have more thrust than the PBS TJ150?
@b101aa2 Really, how much thrust do you think each of those 2 stroke engines produce (15 hp each)?
i want 4 at least this will make the best propultion system for my project but what fuel type is it on lpg,rocket fuel,jet fuel,nitro fuel,petrol?
Turbines may "hog" the fuel, but you must admit they do have a much better power to weight ratio than diesels.
Example:
Wärtsilä-Sulzer RTA96-C, weight > 2300 tonnes, power circa 80Mw, SFC 171g / Kilowatt-hour (used on the Emma Maersk)
VS
3 LM2500 industrial gas turbines: weight 4.672 tonnes each (total 14.016 tonnes), power 25-35Mw each (total 75-105Mw depending on version), SFC (converted from english units) 226.9g / Kilowatt-hour (engine is a derivative of the CF6 as used on the Boeing 747)
so what yer saying is that u basically overcome scale-effect?
holy shit man i would buy one of these and mount it on so many things !
What sort of weight could the engine push on a rolling chassis?
If it out puts 100 lbs it will be OK for most RC jets, is it possible to buy one?
This is incredible but I'm still holding out for the day someone TRULY goes all out and builds a miniature twin-spool turbofan, say 10 stage axial compressor and 2 stage axial turbine with the option for an afterburner. This is a huge step in the right direction. Heck I'd be impressed with any twin-spool micro jet really...
Is that a Scorpion brushless motor for the starter
Could you share the plans with me? I have bought a titanium disc that can be made to 2 fans (turbine blades). I intend to buy more to make 4 or 5 blades. The size of one disc is 128 mm x 40 mm thick.

Bit noisy to put in the boot, isn't it? Apart from that, in a car we don't want thrust but electrical power, so, what can you get out of and how?
modify it by adding a power turbine. Seems like the turbine would be on a separate shaft entirely
How much thrush does it produce , and does anyone know the real price of these engines

Whats the footpounds or kilo newtons on this thing?
Wow, perfectly done.......
Imagine sitting at the stop light and the Jaguar next to you fires up its turbine to charge the batteries.
A few questions. What is its rated thrust? What is its weight? What is its fuel consumption per hour? Can it run off of hydrogen?
Very impressive! What sort of fuel flow range does it have?
IT'S WHISPER QUIET!
+Jesse Stebbins YEAH IT'S SO QUIET I CAN'T BELIEVE IT!! OH MY GOD HOW DID THEY MAKE IT SO QUIET!!
+Alex stevensen WHAT !?
+Jesse Stebbins, nobody can tell by listening to the recorded sound. It will be ear-splitting.
That's right Troy.

Whats inefficient about it?

EnglishTurbines interesting. How did you know it didn't scale? Do you do work on turbines?
it looks like a massive 9mm round with a stainless case and hollow point bullet
Still wont run? After all that work?
LMAO! Like Jaguar owners want to hear that thing charging their batteries? Now, for an RC Aircraft or boat, that thing is bad ass!
great to use for heat /generation as well and combining it with compact 100 kw gen./motors not only for automotive but for home energy supply with locally produced fuels.CIAO GIO .
one of these powering that new passenger drone would be the way to go

I think this a very lovely bit. Of engineering and although it was. Made with other things in mind wonder if it can be used in model aircraft??
That size it's not bird strikes but insect strikes you have to worry about, just joking!!
Funny. I guess one would have to worry about either flying or driving into a bug swarm? :)
How much does this cost and what do you think about putting it on a bike and feeding it with a CH4/CO/H2 mix of gases?
How does this compare is a similar sized MYT engine?
What is the maximum thrust?
Just let me borrow it Jaguar, gosh I'm not gonna break it!! ;oP
wonder how much just Turbo jet will retail for RC use?
How sweet is this unit.Can I buy 2 pls.
Looks like it has surge issues.. I suspect more work on the pressure bypass values and FCU are needed.
Can I have one for review? It would be amazing to do a few seriously awesome projects for social media and RUclips!!
What is the fuel consumption rate?
the best motor pound by pound about ratio power-consumption-weight
What I want to know is how many kilowatt hours it produces at max power and and what rate does it burn fuel? :(
I would be interested to know its fuel consumption compared to a Centrifugal compressor engine of the same output...other than that, very impressive. Bet its pricey though....guess it runs at lower rpms for any given amount of power output..compared to the centrifugal type?
Damn, I missed a presentation by jaguar landrover at portsmouth university, found out on the day you had to register :(
Perfect for cars....thats not noisy at all.
เทคโนโลยี่ทันสมัย..ไม่เหมือนของเล่นสมัยที่ผมเป็นเด็กๆ...สุดยอดมาก
RC types are gonna go bonkers. 😆
whys is to hard to make a smaller version of a jet turbine?
how much Jules does this turbine generate?
It depends on how long it runs.
How can I get one? 😍
how much does it weigh again?
Any blueprints?
