This weirdly gives you a sense of scale, if this tiny little thing is powerful enough to make this possible, it just makes something like a GE9X look even more insane. This is so cool.
You can get a jet engine retrofitted for a LS4 for about 30000 euros. Gives up to 2 m/s. Some pros and cons to jet. Pro, less drag when deployed, good power to weight ratio, Cons. Noisy, start up time, fuel consumption. The temperature is extremely hot at exit but dissipates rapidly.
Granted, I don't know much about gliders, but that's almost without a doubt a Jetcat turbine. Their most powerful of which costs 4,000 Euros. I'm not quite sure how 30,000 Euros is justified for a modification like that. They have a time-before-overhaul of just 25 hours too. Surely a small petrol engine and prop that popped out would be a more practical alternative?
@@karlfriedrich7758 the turbine is just a small part of the cost. There is a significant cost in the fabrication and installation of the armature that holds and deploys the engine, the trap door in the fuselage that opens and closes, the control system to deploy and retract the engine, the fuel system installation and plumbing, the electronics to control it all... the parts are not large but are CNC machined alloys and then some significant work in composites (carbon fiber) to fix the turbine armature to the fuselage and fabricate the trap door. 30K euros is probably a bargain, the technicians who do this work are not becoming rich.
LOL, just checked the AMT website. Yeah, its 31,000 Euros just for the Nike turbine alone. So if you are doing a retrofit installation on a glider add another 30 to 40 thousand Euro for the installation cost of all the things I mentioned in my previous comment.
I completely agree with you, I’ve come across videos of these recently and if my wife hadn’t told me no I can’t have one I’d be the proud owner of one today. So I have to live vicariously through others enjoying the hell out of them
@@johnrobinson4445 Not quite... planes are not gliders inasmuch as gliders are not planes. "Planes" are designed to maintain power throughout the entirety of a flight, whereas the "glider" is designed to "glide". They obviously operate under very similar principles of flight, but are distinct in their primary modes. The jet will assist the glider get to altitude, then the engine disengaged to "glide".
it is assumed that if they use a towing vehicle (even just to break the inertia with an impulse by towing device, winch or even car etc) it would save energy for a greater range and distance
I believe the best solution is the gliders with the electric pop-up boom propeller. It's not that this jet engine or any gas engine doesn't work, the problem is that it takes so long for it to build power and I feel the electric motor is much more reliable.
Would an airplane like this be a good choice for a fuel efficient 1-2 hour powered turbine cruiser or is it something that you fly to find thermals/lift and then turn off the turbine and soar?
@@KB4QAA If you've seen the "I bought a plane and flew across the country" video here on youtube, at one point he's having trouble in Arizona because his aircraft is too hot for his phone to even work, and he's using the phone for navigation.
A jet gives you higher cruising speed but you don't need this on a glider. On a glider you wish high starting thrust this works better with a propeller.
I'm guessing the gross weight of this sailplane is probably around 600 lbs. That this tiny jet engine barely bigger than a football can launch this plane makes me think of their power to weight ratio as akin to a mythological animal.
I have seen the starter on them jets get stuck and not release the clutch and then jet started and sucked in the debris from the starter that is at the front of the engine. I wouldn't want to trust it.
With an engine this size, at full power. You can stick your hand in the jet blast half way to the vertical stab and its not much worse than a heater. The air mixes and dilutes the temperature surprisingly fast.
@@flynntytonidae5631 interesting point. I got my glider license as teenager 41 years ago. Last flight in 1998. I haven't had the chance to see a tow plane launch without a wing runner. Would be interesting to see.
Turbine whine on start up always makes me smile. I love the chally2 tank as I'm Scottish, but the abrams with the Honeywell turbine was a great idea. They're actually really efficient and can run on anything really. 😅
Not a hot start. The combustion chamber and engine is so small, during start all of the combustion isn't complete until there is enough airflow. Lazy yellow flames are okay, hot torch like flames are baaaad.
Nice but I can imagine that if the neighbors were complaining about the noise from tow planes now, this would make them take their pitch forks and head out to the airport. As a sustainer engine though, it is pretty unbeatable especially because of its low drag. The problems with current sustainer engines is by the time you need it, (especially on competitions where you will wait until the last moment) you'd better be in a final over a field because the drag is taking you down fast. If the engine does not start, you will have to land right there. This would give you more time and less risks even if it does not start. I can imagine maintenance would be great as well. Unplug the engine, send it out for maintenance, hook it back up and you are good to go.
Due to the size of this engine, even at full power it is going to make a lot less noise than any propeller aircraft. Especially at much higher frequency, which doesn't travel very far.
I agree and yours seems to be the only comment on that. Not immediately but over time, it will cause fatigue on that tail. There's a REASON top mounted jets on other aircraft have a V-Tail.

These self propelled gliders are just about the coolest thing there is, along with the Sunseeker solar-powered glider.
"self-propelled gliders" AKA "planes". lol
They need fuel to power that engine .. Are there even gliders with fuel tank designed in them? Doesn't that decrease their glide ratio?

Not a silent jet anymore :) Great piece!
This plane is called „Silent 2“ ...😂
Well obviously ............ No one can hear a word anyone else is saying when they're near the motor on run-up. So - Silent (sort of).
It is loud.... but it is silent too...
i didnt hear a thing.. was there some noise?
Silent squad ?😂
If the wife finds out how much you spend on it, she'll be shocked into silence (more apt name should be "Silent Wife 2")
A BIG r/c jet engine here!
looks perfect but < The rear vertical wing is not in danger of melting or burning from the hot air of the turbine;
*Vertical stabilizer
this is the fucking coolest thing i’ve ever seen
Hmm, that little jet engine sure has a pronounced P-Factor pulling the glider to the right!

It's a one man flight, which you don't need another person for launching
@@xuau208 yes, flying alone It os the only opción👍
RC Glider with a realy Semiscale Pilot. Great Work 🤣
Waw
You can already buy gliders with Jetengines. Saw this on the Aero Friedrichshafen 2019, with the full mechanism
I’m not so sure I would want to retract that engine into the fuselage
Typically you leave them out to cool them before retracting.
As I recall, they said that there is a minimum cool down time of 1.5 minutes at cruise.

You wont get a long engine run time, its a sailplane mostly
You've got about 10 minutes of fuel. Get to altitude and shut it off.

@@TheSoaringChannel The U2 is very fuel efficient due to its long Wings, correct? So why not this Glider with a Turbine?
@@sanfranciscobay it is probably highly efficient it just has a tiny fuel tank because its a self launching glider not a plane for traveling in
I'd assume you'd is a jetcat, but I'd love to know what model it is exactly, does anyone knows? Thanks in advance.
Does horrific wet starts like a crummy Jetcat....🤔😏🇬🇧...They eat their poorly designed and made Combustion Chambers too...🤔😏🇬🇧
Now you just have to call it a plane
Gliders: Painted white to reflect sunlight and prevent softening of the resin
Also gliders: 800°C exhaust gas in front of the stabilizer 😂
The jet eflux temperature already decays to only 40*c above ambient at the tail.
@@jdesmo1 that's still quite hot...70 degrees Celsius.

Maintain runway heading is not the case, here...
Gliding is all about freedom not runway heading :D
He turned to get the relative wind directly on the nose.
Duuuude 🤝👏
Hello sir.. Tell me that how much thust this jet engine can produce.. Pls tell me sir... Love from India🇮🇳
what's the thrust to weight ratio?
1 Lil’ Jet : 1 sailplane
Turbine how much kilophonds
Spettacolare. Si trovano di seconda mano i silent jet?
Just like James bond
WHAT???!!
IT'S A SILENT JET!
A WHAT!?!?!
HOLD ON!
Thus should have been the plane at the end of top gun maverick
How cool is that!😜👍🤝
Highway to the danger zone .
That is really neat! 👍
Interesting too heavy on the right rudder error on take off maintained by the pilot to make it look like he “meant to do it”.
looks more like he was heading into the crosswind
Well done.
Which altitude can you get ? Very cool idea
Since it's basically a glider, you can probably ride the thermos and go as high as you like.
I'm guessing the gross weight of this sailplane is probably around 600 lbs. That this tiny jet engine barely bigger than a football can launch this plane makes me think of their power to weight ratio as akin to a mythological animal.
Is this considered glider?
Quite please..Silent 2 is taking off.
And that right there is where you come from kids
I have this suspicion that the people who made it and named it are older and have high frequency hearing loss...
What is the thrust of the jet?
Silent ??
For your own safety stop at Mach 2,5 ☝
That's sohhh cool 😎!
wow gliders are evolving into self propelled self launch aircraft.... airplanes????
I have seen the starter on them jets get stuck and not release the clutch and then jet started and sucked in the debris from the starter that is at the front of the engine. I wouldn't want to trust it.
I have seen air turbine starters overspeed and explode while starting engines on commercial and military aircraft. What exactly is your point?
Perfect 👏👏
Wow
So that's how the airplane was invented!
Scratch-2
Wing to tarmac
Way to track the center line, let alone rwy heading. Bad or lazy airmanship, this is the kind of complacency that leads to accidents.
Lift off, Mach 1, Mach 2, Mach 3...
WOW!!!
Has anyone ever DIY built one of these planes before? For the price we may as well build our own lol
A 1/2 U2 basically
Why 1/2?
I WANTED ONE LOL
Now all you need to do is implement a retractable motor mount to pull the little jet motor back into the fuselage after you get up to altitude!
It's retractable. Here is a cool home build with twin engine.th-cam.com/video/tBfWq5gj5vw/w-d-xo.html
It has that.
Perky little engine!
send me one so i can review
Won't the jet exhaust damage the tail assembly?

Not exactly silent... i prevere those with a electric engine.
What is the definition of silent 🤣😂
Beats waiting for a tug. Not sure I'd be comfortable with that glorified APU screaming right at the back of my head!
Due ruotine in più no? 😄
"Silent"... That's a joke, right?
RIGHT????
so silent
nothing silet about it
Espectacular volar en un aeroplano y so es de noche mejor
What's wrong with having a wingman to level them prior to the takeoff roll. 🤔
Labor costs. LOL!
It has wheels under the tips
Why do you need one on a self launcher? It looked like a demo takeoff anyways. Meh.
Doesn't that defeat the purpose of being able to launch without additional help?
The entire engineering team have gone deaf during prototyping so they truly believe it is silent
WOW!
I love that it doesn't need someone to hold the wings level.
Well when doing aerotows (towed be a plane) we also don't _really_ need a wing runner, it's just ideal
@@flynntytonidae5631 interesting point. I got my glider license as teenager 41 years ago. Last flight in 1998. I haven't had the chance to see a tow plane launch without a wing runner. Would be interesting to see.
That's quite impressive. That accelerates and climbs better than a lot of general aviation stuff. How much thrust do we have there?
Im a heli pilot, I went from Pistons to Turbines, Turbines are so much more efficient and it looks great too, good job

So it a plane now…. I’ve got to be honest putting a jet engine on your glider seems more sensible than not doing.
Right!!
I think combining this with a winch tow to get airborne would be really ideal.
This guys tow pilot is glad he's gone. Way to hold a centerline!
This is just so fucking pretty. Super like
The power of thrust... Very genius..
Thrust is force. Power is force times velocity.
That's what she said ,
It looks like a JetCat turbine. What size is it? P220 or maybe P300?
I just realized how powerful jet engines really are WOW.
That hot start worried me
Not a hot start. The combustion chamber and engine is so small, during start all of the combustion isn't complete until there is enough airflow. Lazy yellow flames are okay, hot torch like flames are baaaad.
Logging single turbine like a boss
*_That's what I'm talkin about ..._*
Sensacional.
??? Silent? My dB meter disagrees,,,
Wouldn't just a single engine two man ultralight be more cost effective? Easier to maintain.
This looks like something out of despicable me
WOW! Great invention! Up Up and away from this world--------- until the world Gravity SUCKS the plane back down to all to itself

Adding combustion engines to anything makes it better!
That hamster looks like a bloke.
Kelly Johnson had the same idea in the 60s except it was in black
aren't you worried that jet exhaust can demage rudder
Another wet start by Jetcat....These tiny Turbojets guzzle huge quantities of kerosine, you'd be surprised just how much....🤔😏😏😳🇬🇧
I presume the fuel capacity is such that you have the choice of self-launch OR self-retrieve?
WOW so cool!
Great zombie plane. Quiet. 😎
Jest plus, sam wystartujesz.
