NEW Aerospace ENGINE Destroys ROCKETS 

It would be good for you to take us one level further/deeper. a) materials b)fluid dynamics c)logic/computer control d) instability sources of continuous D .........

Also interesting to see that Aerospike-type nozzle is being tested alongside! As an Engineer who loves CFD and Aerospike, I would love to see what the future holds!

I’m a little late to see this… but I have some experience working on/with linear aerospike engines. I worked on the Lockheed Martin X-33 (the prototype technology tester for the LM VentureStar), and I spent a lot of time with the good people at Rocketdyne, who were developing the XRS-2200 Linear Aerospike engine. I have always wanted to see this concept in use, and I attended most of the XRS-2200 tests that were performed at Stennis in Mississippi. These engines were very, very promising. To me this was the most important technology to be tested on the X 33 as everyone knows the X 33 was canceled in March 2001, but we did at least get working linear aerospike engines and we had some data on those. The difference that I can see between the engines you’re talking about (with a pulse detonation in a circular motion around the periphery of the ramp) and a circular aerospike engine will be that a circular aerospike engine would have all the thrusters operating simultaneously, and continuously, rather than pulses - moving around the periphery in a circular, tornadic fashion. I like this idea, except I would be more comfortable if the thrust were more symmetric about the center of the circular ramp. In other words, why couldn’t we have two detonating simultaneously across the center of the circular ramp from each other? I’m always a little uncomfortable about any kind of nonaxisymmetric thrust on a rocket engine, even if the pulses moved very quickly - there would still be some thrust vectoring (TVC) that might be an issue. I think this is something we would want to avoid. The concept of aerospike engines with the external ramps is a very old one and it’s back to the 1950s. There was an instance of somebody (and I can’t member who) that put a circular aerospike engine on a barge… and they were able to get some good data from that test. Great video, thanks for posting this! Cheers from New Orleans. 🥃

RDE looks like it oculd be the next step in Aerospace engines. Computational fluid dynamics, as my favorite Physics prof at the U of A used to say, don't forget to carry the one.

Great video! I just learned about this for the first time, but this short video really covers all the bases regarding limitations of the pulse detonation approach (shock wave noise and vibration), along with the possibility space for future developments (AI-developed materials for continuous pulse detonation commercialization; rotary detonation, essentially a continuous series of timed detonations). Mach 5 is a nice dream but the materials to support that using pulsed detonation still need to be invented!

Thanks for taking the time to make this video! It makes a very complex subject more understandable! Well done, Cheers 👍

I like the format of your video - no lengthy intro, dense technical info unlike dumbed down pop science channels. Love it!

The RU-vid creator Integza made a really fascinating video with some scientists who're researching the rotary detonation. The video demonstrates the force and heat produced from relatively small RDE. Pretty cool video that I would suggest to anyone interested.

Great Videos, we appreciate you taking your time to produce them !!

If they really get an RDE working, ready for production, it's going to change more than just orbital economics. It will change aviation as a whole. Definitely one to watch.

i am happy youtube suggested this video to me, i never heard about an RDE or detonation supersonic wave. makes me want to know more about these topics :)

It’s ironic that the one main flaw in the internal combustion engine, the air flow around the edge of the bore to piston, is the bases of this technology. Love it and love your content a lot.

Cool, I always wondered about these. Looking forward to more now.

Rotation detonation ,never heard of it,amazing and the alloy,thanks

Great video! Was expecting something different from the title but pleasantly surprised the space war hasn't started... yet

So much great info in such a concise presentation! 🙂

I always wondered why this promising propulsion system is not heavily used in aviation and rocket engineering. Thank you for explaining, great video!

They'll be fine for thrusters but long burns will hit the cooling barrier that confounds aerospike engines: The cooling demand rises by the cube and the cooling ability rises by the square. The NASA demo engines used a cooling method that's too heavy for flight. Once again Earth just barely lets us into orbit, but we're getting better.

I didn't learn a single thing about this engine in this video besides what alloy it's made of

Perfect demonstration video. Controlled detonation is an ultimate logical future of chemical reaction thrust!

Awesome video bro, keep up the good work, kudos.

Just some helpful notions. 1. all materials are moving at a intermolecular level. 2. All motion is temperature... just depends on the scale and permability you are trying to reffer to. 3. All alignments are challenged simply by existing, let alone if you are exposing them to explosions. So the tighter the margins, the sooner it will need corrrecting, the lower ability to correct the sooner it will fail. This technology can work. It needs strong attitudes willing to redoubt preconceptions and offer up sophisticated solutions to correct for problems rather than trying to simply change materials. ultrasonic pulses for example are under explored. 4. Fluid dynamics based on a static container can make for more complex calculations than if one was to use a dynamic container, i.e. ultrasonics or laminar flow calipers, that are able to interface with AI and work out what works prior to formulating formula.

Very interesting rotational explosions that create some awesome thrust. I was thinking about linear explosions to create a constant thrust.

Thanks for a very rare video; NEW facts presented without hype.

Another fascinating video. Thanks for making it. I’m very curious what AI engineering systems may come up with for this class of engine.

Nice presentation . This might turn out to be a major breakthrough

Fascinating. I've been following this concept for some time. I am curious whether you can express the output in terms of Isp ( Specific Impulse ).

Well explained video, about a very interesting subject! Thanks for posting!

Great video. Like Robert V. ... all important bases covered!!! Thanks.

The German V1 cruise missiles they shot at London in WW2 used a pulse detonation engine. That is why they made that infamous prattling noise people who experienced it often mention. So it can't have been too complicated a principle if it predates the first fully functional jet engine.

Very cool concept

Great information. Thanks

Also reminds me of the nuclear rocket detonating nuclear bombs behind it to accelerate it.

Awesome video thanks.

Interesting. I Loved the, tell tale, spaced Diamond Con trails of the 90s-2000s. I wonder whatthese will look like.

What a time to be alive

Love it. Very interesting video, and it’s very clear to me now - all we’ll have to do is place this new engine in front of all the rockets so that they are engulfed in the superheated exhaust. That should certainly destroy the rockets. Great video 👍

fascinating directions this can take. with materials and 3d printing more strange designs are possible

Absolutely amazing.

This type of breakthrough in science always fascinates me ever since I was a kid👌. I thirst for knowledge

Thank you for the information

I know what you're trying to do, think of it as a sprinkler. Every time the sprinkler lists off a water spout there's a valve that pushes forward and then hits it to turn this all it is. So basically every time there's an explosion it opens up a valve and then once the bow comes back it turns it and then it opens up again so it means you'll have a constant variable explosion in the same or in different valves without having to worry about the same valve being damaged. It also allows it to cool itself down as it changes between valves like a sprinkler would do every time it turns.

NASA's new engine is also an arrowspike, that maintains better thrust from ground presures though vacuum of space.

I think this needs a lot experimentation with many different designs, which might then result into some hobby designer finding a weird solution that is designed in a way that it fixed most problems with keeping the detonation rolling.

looks like the future.

Excellent video 👍

Love the video thanks

My neighbors already hate my cars exhaust. I can't wait to unleash the exploding tornado.

awesome video!! I would love to work on things like this!! I'm good at figuring things out!!!!

An exploding tornado. Why does this sound slightly worrying? 😂

Thank you for the insightful video. In 2021 the Japanese space agency JAXA sent into lower earth orbit a rocket retrofitted with a rotating detonating engine, the engine was fired for a bunch of seconds dimming the test successful. the rocket was splashed down into the ocean afterward.

3D printing engine parts is so cool since it allows far more complex parts and substantial (low volume) production cost savings. Testing and modifying the design is much faster and cheaper too

A Glimpse of Eternity beckons me of faster than light speed craft

During WWII the Germans experimented with Ram Jet engines using coal dust as the primary fuel. The engine was to be mounted on a Feisler Fi-103 or better known as the V-1. The engine produced similar power to both diesel and gasoline. It never got past the experimental stage.

LOVE IT subscribed

Mind blowing!

Good stuff

It’s like a hybrid between rocket engine and ICE and rotational concept will allow a constantflow through aero spike nozzle out going gases and keep giving constant thrust great idea

Great video. Technical enough to understand how it works. But simple enough that us novice do get lost. 😅

Thanks!

This looks cool, I like it

Looks to me that RDEs have a very bright future and I think it is only a matter of time. It will take time to figure out the proper configuration and dynamics for this engine to take us to the next stage of Human space exploration. If we can manufacture an engine that is capable of taking us to Orbit in the way that this engine does, and make it so that it isn't trash after the flight up, then we can begin to make them bigger and more powerful to the point that they are reusable, and fully capable of operating in the vacuum of Space, then this engine is going to be either the engine to take us there, or the father of the engine that'll take us there, or perhaps the grandfather... but it is obvious that we need something more efficient and more practical than a Rocket engine.

Imagine what you could do if you could control the electromagnetic spectrum down to the atomic level.

Fascinating 😊

Some nice B roll my bro

RDE + aerospike should prove to be quite efficient!

Nice one, which software do you use for your video illustration / animation ?

I came up with a rotary detonation type engine design back in college like 15 years ago using hydrogen and oxygen, but i never pursued it very far as it was very expensive.

NEXT LVL GEN GO GO GO

Quite interesting video. I wonder if the RDE would actually be quiter. Because once a machine or device moves alot of air or gas noise is unavoidable.

*_Beats Wiley E Coyote's rocket by a mile... time for new technologies.._* Increased noise was listed as a 'negative' attribute. As soon as RDE is high enough, the thin air will no longer transfer noise. Vibrations from extreme noise (high pressure) will stop outside the RDE, but vibrations will continue inside the RDE as they are transferred inside the actual material RDE is constructed from. *_3D printing complex shapes out of new materials will result in successful RDE._*

damn..thats actually pretty effin clever

When you started this video, the first pulsing design (40Hz) remainders of V1 rackets!!!😮😮😮 Pulse action was achieved with combustion chamber having spring membrane and long exhaust tube.... Worked with pure Alcohol and 80% Hidrogen Peroxide!!! They build it 83 year ago..😢

I'm a little worried about the rotary component of RDEs introducing guidance issues, but I guess that could be dealt with by having them in counter-rotating pairs like drone rotors.

Three of the biggest challenges I see is a combination of resilient materials precise cancellation of heat and shock on the inner surface. If the oressure and heat extremes can be sensed and responded to before they reach the combustion wall then it is s matter of providing adequate cancellation support.

lol I guess detonation is when your car stalls out for a second but keeps putting out fuel and then suddenly it all detonates inside the exhaust system blowing the muffler clean off the car. Thanks Jeep ZJ

Jack of all atmospheric pressures, master of none.

Clearly, we are on the cusp of better technology, and its applications will be based on cost over current tech. Perhaps, a new kind of jet for instance? Would it still be called a jet, and would it imbibe confidence in its use? Surely, thats yet to be seen. Thank you, for your efforts in bringing it beyond a test stand! Good Work!!!

This and most other videos about RDEs don't convey the absolute ear-splitting, glass-breaking, Aztec-Death-Whistle-esque *scream* they make when they fire. Like something fundamental to the laws of physics is crying out in pain.

These will do awesome in my new Pod Racer.

Interesting Video, So in a I.C.E. you have deflagration as opposed to detonation, It looks like I'm already subbed to your channel, I will turn on all notifications, as I enjoy this type of content, THX for posting. 👊 😎

Very interesting.

A 25% increase in efficiency will make this happen. Less components and thus increase reliability will also be a boon.The issue now is scale.

Very cool

I made 32 inventions in the 80s and 90s. I figured out how to make error free rigid memory disks doing epoxy fluid dynamics in my head. Thanks for the close-ups at 3:50-4:03. How did you make the ripples between the walls in a high pressure device at 4:50? Where to guide the pressure to? Verrry interesting...

making the explosiin comes from plasma or electrical discharge might be something they do later , so you will have a small neuclear reactor that will power the electricity needed to generate enough plasma pulses in the engine chamber

Material Science always follows the engine concept design. This is going to get interesting.

I just want the opoc engine to come to market. I would love to see them made and sold as crate engines so I could put them in any kind of car.

silicone graphics and processing is becoming more and more advanced each year. This RDE technology will be perfected soon. Well done NASA

Amazing

As someone who works with AI (in a FinGech capacity), I’m dubious about its real world impact. The hallucination problem (despite RAG models etc) is significant enough to make it redundant when dealing with problems that require robust solutions.

What if the exhaust never left the combustion chamber but is kept at a high pressure inside ? The unequal pressure should cause the rocket to move in the direction opposite where the exhaust would normally expell. The exhaust could be kept from leaving the combustion chamber using a intense laser beam aimed at the opening and causing a explosive shockwave to form from the exhaust that would push it back inside. A laser will not produce any significant opposite reaction force when it shoot the beam. This method can save a lot fuel from being wasted as normal rockets would do.

oddly I imagine a time when this technology is in a pocket lighter sold at 7-11 and in entertaining shapes while future propulsion is bending time.

Some of those high temp parts look alien.

You have missed a key point. It is not an explosion that drives a piston but the expansion of hot gasses, including the non-combustible ones, The explosion or rather a fast burn (a detonation would blow a hole in the piston) is usually arranged to be completed on the compression stroke before top dead centre, and then the expansing gasses drive the piston. And a turbo jet works the same way, it is the expansion of hot gasses that drives it. When it boils down to it, these are heat engines.

Damn I see and understand already. Why did it take so long.

I love how research and development can create better solutions for transport. I have to wonder if there is yet an undiscovered technology that will be a quantum leap that will allow speedy transport to other planets or even other stars.

Brazil is in the top of Niobion production !

2:47 i love the concept "in theory" free contents with clickbait title LoL
