The Tip-Jet helicopter passionates many since more than 60 years... The Djinn S) 1221 was mass produced for the army then used in the civil as a crop spraying tool. The concept was abandoned for performances and political reasons. But thanks to the new technologies we are able to bring it back to life. This is the C-56 XERUS program that I designed based on 30 years of experience and being the father of the XENON gyroplanes series.
Our current Djinn is as brand new as it can be (only 1 hour) and is used to study it and be the inspiration for our own design. We have proceeded to CFD simulations and we can confirm that this concept is worth it. In the mean time it is a piece of History that we cherish.

Have never seen this type of helicobacter it's using a jet blow to councel torque, it's amazing
Same as a NOTAR MD500, NO TAil Rotor, but I didn't notice that on this one. ... Oh, exhaust shooting at the rudder??? Oh, I see now, It's a Tip-Jet system. No need for tail rotor. ruclips.net/video/VCZ2jhE0Azk/видео.html
Il n'y a pas d'anti couple pour corriger le lacet ??
This was such a clever concept that I'm surprised it never caught on. It worked like a rotary sprinkler. It simultaneously solved most of the problems with helicopters, like complexity, blade icing, and rotor torque. You can probably think of a few brilliant ideas that were forgotten.
il perd pas mal de tours en vol, non?
Oui, la turbine est totalement usée, elle a été remplacée peu après et tout fonctionnait parfaitement avec le nouvelle turbine, dommage qu'il n'y a pas eu de vidéo pour l'illustrer
it look like the rpm is down

I'm a fixed wing pilot . I love the Simplicity of this aircraft. If engine failure occurs how is air pressure maintained for directional control during Auto rotation?
The rudder would work as long as the helicopter is moving forward but the rudder would become less effective as airspeed/air flow reduces.
Bleed air is not enough power, in my opinion or get bigger engine
COOL!
Could I buy this??? Email me at horsemnn@aol.com That is: Horsemnn@aol.com If your price is within reason I will buy it. You said you will build it with more power. I would rather buy the more powerful one.
No tail rotor??
Not necessary ! Because air jet from the blades cancels tail rotor complexity French helicopter to pilot
It looks like a Fairey Ultralight knock off
First flight of the Djinn occurred on 2 January 1953; first flight of the Ultralight occurred on 14 August 1955. The Djinn rotor was driven by cold pressure jets (unburnt air); the Ultralight rotor was driven by weak mixture hot pressure jets (burnt air). Theodore Laufer, who designed the Djinn rotor drive, and Freidrich von Doblhoff, who designed the Ultralight rotor drive, worked together on early tip jet driven rotors at Wiener Neustädter Flugzeugwerke (Vienna Aircraft Factory) during WW2, after which the team was split up between Britain, France, and USA.
How much cost a modern turbine able to replace the original one ? Would there be a lot of work to adapt a different one ? Was the original computed for the Djinn specificity ?
The cost from a turbine is gigantic, and why replace to original turbine? It's a Turbomeca turbine, world best brand for helicopter turbines...
Why is it losing rotor rpm when taking off
turbine is out of TBO, will be replaced after this test
Really struggles with maintaining rotor head speed.....no mechanical connection I'm guessing might be the reason.
no, the turbine is out of TBO, was replaced after this flying test
Se splendide SO-1221 Djinn en état de vol sont rare de nos jour! Merci pour le partage.
Finally, a revival of a dropped technology? I don't have a clue about airworthy survivors.
Yes it is. Besides about only 5 remaining in flight condition.
@@celierraphael471 How does it fly with only one main rotor and no tail rotor?

Bonjour...moi j'était mécano dessus pendant plusieurs années...ça me rappel des supers souvenirs...ça me manque beaucoup...j'y pense très souvent...et ça fait du bien d'en revoir un... Merci pour ces belles images...
xavier-marc benoit Au plaisir de se parler en direct.
@@celierraphael471 Je veux bien mais de quelle façon...ça devrait être en privé...parce qu'il y aura beaucoup de détails concernant mon expérience pour des personnes de grande valeur...etc...

There might be an electrochemical fuel/engine option that would make the jet moot.
Very nice efficient design. Turbine produces high pressure air for rotor tip jets, very popular during WW2. Research "Airjeep" no transmission, no tail rotor 1/10th the moving parts. Cheap to operate 15gph fuel burn.
Correct.
so about 3 times the fuel regular helis use. do you know how its overall cost compares to regular helis?
@@beeqool No, not 3 times the fuel burn, only about double, but being an experimental, you're not bound to Jet-A which is basically glorified diesel. You can run turbines on kerosene, diesel, even cooking oil, which is what we use in our Allouette turbine, cleaned and filtered used cooking oil from restaurants. In emergency cases you can even run auto fuel for a short amount of time to get out of an area and back to a diesel pump. Furthermore, the absence of the main rotor transmission and clutch assembly as well as the tail rotor gearbox and drive assembly cuts the maintenance costs Incredibly lower than a fully geared helo. More comparable to a gyrocopter in maintenance. The cost of operating any equipment, being a truck, tractor, airplane or helo, is calculated per hour with fuel burn and timed components and wear components and pre scheduled inspections. When that calculation is used, this little helo is Much more efficient and less costly to operate and maintain than a standard configuration helo, provided you can accomplish your task with what this unit can deliver.
@@timmorris3056 thanks for first hand info. do you know why nobody makes these? could these be made with ice engine to make it even cheaper?
@@beeqool Watch "One Man Helicopter Jet Jeep Invention Newsreel PublicDomainFootage.com" on RUclips ruclips.net/video/MSDZ2x1LgMc/видео.html
not a bad gyrocopter
This is not a gyrocopter or an autogyro. It is a tip jet driven helicopter. Driving the rotor by means of tip jets means that that there is no need for a tail rotor, as there is no drive shaft producing torque reaction on the fuselage. The rudder provides directional control, even at low speed, as the engine exhaust is passing over it. This design uses compressed air without any fuel combustion to drive the rotor. A similar British design the Fairey Ultralight used tip jet drive but also burned fuel in the tips for extra thrust.
🤔 How does it compensate anti torque. Is it with the bar just beneath the main rotor?
I'd say the rudder, from a big blower blowing on it. and no mr transmission only mr tip jets.
@@sparkyr22 thanks for the info, first I thought was kind of co-axil.
There is no anti torque required. Because the rotor is driven by the tip jets, there is no conventional rotor drive shaft so there is no torque reaction on the fuselage. This is the whole idea of tip jet drive. The rudder is there purely for directional control. At zero or low sped the exhaust gases from the engine pass over the rudder surface providing flow for the rudder to generate side force when deflected from the neutral position, and as airspeed increases the ruder becomes more effective.
The bar below the rotor is a stabilising device. The centrifugal forces on the tip weights tend to keep the stabiliser bar perpendicular to the axis of the rotor. It is mechanically connected between the pilots flight controls and the inputs to the pitch change arms on the rotor blades. If the rotor is deflected by wind gusts, the effect of the stabiliser bar is to make automatic correction to the rotor to compensate. This system was perfected by Bell on the Bell 47. It was designed by Arthur Middleton Young using self built models.
@@alanwhitfield1907 thank you for the information. The last time I heard 'tip jet' is during my traning as and aircraft technician 1986. Forgot all about it. Your explanation bring back memories. 👍🇧🇳
To all, We are currently running our program C-56 XERUS tip-jet helicopter, modern version of the Djinn here shown that I own. Follow us on www.celiergroup.com where you can see the new design. On the actual video it was tested with the old engine, not enough power due to out of TBO engine. We have replaced it with a brand new one latest edition. We have now the full power and a little more. Extremely easy to fly as torque less helicopter. No "deadman" zone, no tail rotor, no transmission that can break. But as originally built in 1960 it is noisy and fuel greedy. This is all about to change with the C-56 XERUS. It will be fully EASA certified as 4 seats (on our website at this point is presented the UL version, thus for the EASA version the MTO is 830 kg) , modern turbine engine, modern blades, Carbon Fiber fuselage, long range and higher performances. We are currently proceeding to all CFD simulations. The EASA version shall be priced around 700 K. EUR. More news to come. Stay tuned.
Very interesting project. Exciting ! But very high price. I wish it could rival the Charlie Kompress kind of which is not cheap either :-( but less than a quarter of yours. Customers will have to be extremely technology enthusiasts, and rich. Helicopter tragedy...
@@soliv27 just go find an old army "airjeep", tipjet single or dual seat, very popular back then. Should be some available.
C'est l'hélicoptère le plus facile à piloter......j'ai eu fait de l'épandage avec....mais je n'ai pas pu récupérer les machines. A quand le "Xénon" avec un plateau collectif ,?
Reply to all. I am the owner of this amazing machine, it has now the latest version of the engine providing 105% power. The original engine was really tired. All brand new now. We are currently preparing through our C-56 program the modern 4 seat version. Keep tuned from our website www.celiergroup.com REPLY
Salut mec...moi j'était mécano dessus pendant plusieurs années...ça me rappel des supers souvenirs...ça me manque...j'y pense très souvent...et ça fait du bien d'en revoir...
C’est bizarre j’avais plutôt entendu que c’était le contraire qu’il était plutôt difficile à manier à l’époque cet hélicoptère ?
Great for hover autos
Perfect machine except that droop! No vibe , big strong rotors ! Who is the Broker?✨👍🏻
Idiots Why make such a loud sound from the first frame?
I think it is the noise of that 2 stroke air-cooled engine on top of the turbine, which I think is used as the starter motor.
The most conceptually elegant helicopter: the transmission is just ducting. A shame it never caught on.
I suspect the "majors" of the day didn't need any foreign innovative competitor to breach into the business. The US Army tested it I think .
Lookup Airjeep, US military
@ryan allemand fly it just like a gyrocopter and you're fine, don't try hovering more than enough to land.
I thing it's that the fuel consumption is just to great . ruclips.net/video/lDOuoG6ljZA/видео.html and maybe this You Tube post is just to grainy.
@R A Tip jet helicopters are wctually very tolerant of this... A conventional helicopter doesn't have nearly thr amount of torque these tip jet rotors can produce... I don't know about all of them but the Fairey Ultralight had a governor because overspending was an issue with small throttle application. They all suffered from noise and heavy fuel consumption (driving a gearbox is more efficient than a compressor) though I would think it could be reevaluate now... would think modern tech could bring costs down considerably
what are you trying to do here in this video? ive read about these tip jet helicopters, from what i understand theyre better than regular ones in all ways except about twice the fuel consumption right? can you compare what their overall costs are compared to the same size conventionl helicopter?
@Joseph Smith yes me too. they appear mysterious to me. theres not much info about them. i know many companies have tried to develop them but for some reason they all failed.
The ideas been there from the beginning for copter design ruclips.net/video/lDOuoG6ljZA/видео.html .
Super ! Le Djinn est l'ancêtre des Alouette...
So Cool! One of my favorite copter ideas .
where can i get the rotor hub plan?
We are selling my father's Djinn. with two spare engine. Any one interested in Malta?
Please call 208-886-0301 in the states thank you Ed
Ok, trashman269@gmail.com
@@landtrust7341 did you get it yet?
Haven't heard anything yet. Ready to go when they reply. We'll definitely do a few videos, and the mods we have prepared for the pressure system, which will allow sustained hover, and quieter operation
Significant rotor rpm droop.
Almost there!!! Need a little more bleed-air. Try the next engine size up. That should do it. Nice job!!!
Also needs a tail rotor to prevent the spin!
@@GaryNumeroUno No spin on the Djinn. This is a tip-jet rotor system.
Magnifique! souhaiterais connaître l 'adresse du propriétaire

The concept is Old. My father did all this in the US..... It works well, except for the fact that it needs a 4 bladed system and no turbine supplies enough bleed air in sonic volume. Turbine running a 2 stage compressor works awesome a d turning the rotor rpm up
