[@Dangineering]

Thermodynamically 80% seems a bit dubious. The maximum thermal efficiency of any Heat engine is in reference to a Carnot Heat engine which has an efficiency of: n=1-Q(low)/Q(Hot). Since Q(low) {the external sink} doesn't change in temp that much then that means Q(hot) must increase. The same material properties limiting traditional engines are also at play here. You can only go so hot until Q(hot) is so high that it melts the materials. Unless they have a published paper to back this up I am going to be extremely skeptical.

With the rate of 20,000 revolutions per minute, it can both seal as equal as conventional combustion engine and also produce an incredible power output.

[@andykerr3803]

Without knowing specific details, you can see there is a lot of potential for both internal heat barriers as ceramics and also internal catylalytic surfaces. The Wankel was bad in this area needing lots of cooling, resulting in heat loss. This one may be better or worse, we'll see 👀

[@oliverscorsim]

I actually agree alot with you as a builder but I am very Impressed by the expansion ratio this thing is capable of along with it compression ratio. Having a bigger expansion ratio is very good at making tq. I see issues sealing with the claimed rev range. It seems like it seals like a roots blower and that's fine and dandy but leakage happens and I understand the prechamber is used to give a buffer zone pressure wise to seal the two sections off. But the hot side is gonna get too hot. I don't see how this would work efficiently.

This design works on paper. The compression rotor is a great idea. Look at the surface area of the hot side upon ignition: 5 of the 6 surfaces produce NO work. The total surface area is huge compared to the "piston" area, even if you only count a third of the expansion (as it's already burned and expanded and is only waiting to exhaust). You could stack this into a multi-rotor design and add a blower. I would love to see a Real One in action.

[@reason2gether]

I have a similar engine design idea that I worked on back in the late 1980s. Mine has all the rotors on one axis and multiple firing sections so that RPM and Torque can be increased just by pulsing the ignition and fuel injector more frequently. The downside to the one shown here is that it has two opposing rotors joined by gear teeth at the outer diameter. This will have high inertia loads under high load and rpm, which will probably quickly wear out the gear teeth keeping them in sync., especially after many abrupt acceleration and deceleration periods. Other than that, the idea of using totally rotary motion is the best advantage to this and my design engine. There is no wasted (reciprocating) motion.

[@desertdan100]

I look at it like a helicopter or jet engine. Spin it up slow and bring it down slow. If you are using it as a generator for batteries and a traction motor, I think it is just the right fit.

[@yvesstocky9936]

Draw something very similar to yours in the 90ies. Did you ever build a prototype?

[@pihermoso11]

There are gears which the teeth are tipped with magnets (probably neodymium) so there is an air gap between 2 opposing gears, the repelling force of the magnets eliminates friction between 2 gears, but the question is would the magnets lose some magnetic power because of increased temperatures? These kinds of gears could be helpful in rotary engines..

[@willyjimmy8881]

As the rpm increases the gap between the gears and rotors would close due to centrifugal force. How much I guess depends on material but seems like a limiting factor. As well as balancing the rotors with that big tooth hanging off one end.

It appears maintenance would be far cheaper and simplified as the motor itself could be swapped out for a new/reconditioned core in a very short time.

This seems great! Not sure if anybody reads the comments, but there's some great ideas in them as well. My idea would move the exhaust port to be timed and exposed later in the expansion stroke to maximize power capture capability by the engine. This small tweek could yield greater fuel efficiency from each cycle.

@@BloodSteyn There's also Liquid Piston as an inverted Wankel engine, good for generating current

[@chrislatchem1854]

I have my doubts about the thermodynamic efficiency. Efficiency is directly related to the absolute temperature difference between where the work is extracted and the temperature of the heat sink at the other end where the heat is expelled. From what I see the fireing cycle is almost the same as with any piston engine and that limits what temperature you can be operating at. In fact what makes turbine fan jet engines less efficient than piston engines is that the blades have to operate in a high temp. region all the time, few materials can last the peak temps that piston engines extract their work at, because pistons, valves etc. get to `rest`and cool off between cycles (even at 20,000rpm).Turbine blade materials are exposed to continuous hot gases limiting this temperature to what the material can stand. The rotation and " lug" division into expansion compression zones are ingenious and interesting (getting rid of reciprocating masses), though! Stil see seals (as per Wanklyn) and gear problems as issues. Was that cooling water pouring out? Will need to see numbers for fuel efficiency, and seal life...Burning hydrogen (with any IC engine) interesting but how to carry enough mass with you, and infra-structure ?

One of the reasons pistons engines work so well is that sealing, even with its own set of challenges has been solved. Only issue electricity is facing is energy accumulation being heavy while charges have no weight, spending time and money on a new dead dinosaurs burner doesnt seem probable. Good eye there it looks like going on helping wheels.

[@brianmontgomery350]

I was thinking the same thing. The tight fit between the upper and lower wheels has to be so tight to work. Blowback will erode the wheels and make the gaps bigger and bigger. This is why the rotary engines fail when the wipers wear out every 25-35,000 miles. This one would be no different. If the wheels are too tight, they won't turn. The heat cycles will destroy the engine. I don't know why we can't learn from the trains and have generators run the electrical cars.

[@TimTamsLOL]

@@brianmontgomery350 odd word choice; "blowback" causing "erosion", what? Apex seals wear out because they're a concentrated point experiencing enormous friction at high speeds - they are simply mechanically punished and can't be eliminated from the design. Nothing to do with this engine.

[@TimTamsLOL]

The theory as I understand it is that the rotors don't need to seal because they leak by design. Given the proposed 200psi intake pressure, and assuming a high enough compression ratio (not disclosed) to achieve chamber pressure despite the losses, the volume of air lost to the leaks will have a small enough impact that it can be ignored. In the demo they would be feeding pressurised air from an external source as there'd be no point building a custom charger for the proof-of-concept when it's already a solved technology. The main question I have is around emissions - they're using semi-direct injection of fuel which means more time for fuel-air vapour to escape rather than just air, which affects efficiency, and the same can be said for combustion gases. I think this engine's equivalent of a crankcase needs to be an active component of the air intake system to ensure complete burn. That's probably something they intend to do as part of the charger design if development reaches that stage. side note: I wonder if this can be made to run on diesel

[@HarmonicResearch]

The seals will work better than a wankle rotary engine because the rotor is not asymmetrical. It doesn't have to bounce around as it rotates. It simply rotates in a circle like a lathe. This makes it easier to manufacture and more reliable because simple rotation under stresses the bearings and maintains symmetry longer.

[@bambambundy6]

You hit that on the head!

[@DrBernon]

Not so sure... They will have thermal expansion to deal with, and also I see no way how they can oil those without pumping oil in the combustion chamber, making 2 stroke like emissions.

[@HarmonicResearch]

@@DrBernon Thermal expansion can be handled with the correct alloy combinations. Side seals are easy to accomplish with linear oil rings. The diameters are the tricky parts. They will need spring ring seals similar to the wankle, but will be easier because of the perfect rotation.

[@DrBernon]

@@HarmonicResearch Look closely at a wankle engine picture. The seals are not that different to a regular piston. They are metal strips at the triangle faces, and a cylinder at the tips. It scrapes the walls just like a piston ring. This thing needs a ring that is going to grind always at the same spot because of the circular motion. The oil will not get pushed between the metals. And the thermal expansion will affect it no mater the alloy combination, because the engine still has a hot spot on the flywheel/combustion chamber thing. So the flywheel will have an asymmetric expansion, and the combustion chamber also has the same uneven heat distribution problem. Those rings not only need to seal a fast moving disk, but also wiggle down and spring back, 25000 times a minute.

Interesting concept, but until I see much more real data, I am skeptical.

It is coupled to an 8 speed transmission to help make up for the loss of torque by using HP in the higher rpms. It tows very well for it's size. Now spin an engine 4 times that rpm and you can do the same work with 1/4 th the torque. This engine would be better suited for power generation than mechanical use unless you had a whole lot of gearing or variable transmission output.🙂

LET'S SEE MORE OF THAT WORKING ENGINE.

[@TickyTack23]

You know what I find unusual about all these new age engines? It's full of animations, and theory. But not a single one will go out of their way to put the engine in something like an ATV to prove it can move a person.

[@leifhietala8074]

Robovoice. Prove you're human.

[@AudiophileTommy]

If it is a robo voice it’s one of the best sounding ones I’ve ever heard for sure !

[@whydahell3816]

I think add 3 more 'combustion' lobes on the same rotor.

[@joeseda8102]

You were thinking just like me! But I was thinking more like a pair of center intake rotors sandwiched between a pair of compression /combustion rotors on either side spaced 180 degrees apart. That would keep the majority of the heat on the outside rotors that can be water jacketed/cooled. Essentially it would be TWO motors working together united by a single inlet set of rotors sized to feed both motors. Exiting HP/weight/size ratio!

[@michaelharrison1093]

At 6:43 this engine is compared to other 'alternative' engine designs while dismissing these other engines as 'mere concept engines' - actually these other engine concepts where actually built and run on engine dynamometers in order to measure their thermal efficiency. I can attest this on the basis of actually physically being present for the dynamometer testing of one of these engines. I predict that this engine will be exactly the same as these prior alternative ICE designs in the fact that the claims being made prior to any dynamometer testing suggest that the thermal efficiency will be way superior to existing ICE designs however the actual dynamometer test results will not be able to back up the outrageous claims. It is more than likely that the thermal efficiency will be lower than a typical mass market automotive Honda/Toyota engine, but with a number of other practical issues that come to light based on real world testing.

[@olivertoeknuckleiii2093]

Every great leap in technology throughout all of human history has come with substantial (and warranted) criticism. Thank God the greatest minds don’t buckle or fold to it. Give them some time to prove the concept. It looks awesome! As materials and production technology improves, this gets closer and closer to reality. Plus- it will make NOISE!!! Something that all gearheads will rejoice in.

[@alterbart7916]

It looks like a dumbified version of the twin screw compressor. These devices have a very narrow effective range and will not hold the compression ratio promised. This is the major killer. here are also tons of other problems like thermal expansion, pumping losses, etc. Not livable.

[@tiandaotan]

In a harsh working environment of extreme heat and pressure, anything more than three moving parts in the combustion chamber raises red flags. Most importantly, no proper sealing solutions for so many areas will decrease efficiency and causes safety issues. Not to mention the cooling and lube. It has some merits of generating large torque and long working travel distance.

[@buildingracingvideos4714]

Very bold power to weight claims for an engine that hasn't run on a dyno. What's cooling the hot side rotor? With no breaks in combustion and no evaporative cooling from fuel the hot side is going to melt itself.

[@johncunningham4820]

They are an Aerospace Company . Fun Fact , TurboFan Jet Engines combust continuously and the Uncooled Power Turbines don't melt .

[@bretbradbury5559]

Being from Texas, I know the smell of BS all too well and this has a smell way beyond.

[@ledsalesoz]

Possibly the first time I've agreed with a Texan (knowingly), this just smacks of the hundreds of other "revolutionary, super efficient" engines that have never come to pass because they were all BS.

[@bretbradbury5559]

@@ledsalesoz I don't have the time to do the research at the moment but it seems like a situation where they might be vying for investment capital so they can burn it on coke and hookers while acting like they have something worthwhile to invest in. I'll be eating a helping heaping of humble pie if this comes to fruition by their hands and the numbers play out accordingly.

[@deanx0r]

"Astron Aerospace cannot be underestimated either [...], because we can see it in its name Astron --Aerospace--" I am ok with channels presenting new design concepts that they may not have much expertise about, but some of the word salads found in this video take the channel from zero credibility to BS channel with a bridge to sell.

[@ft-shareinternational2146]

I'm sorry if my English not good enough because I'm still in the learning process 🙏

[@BoBXygene]

i'm a believer on this one, it's elegant design and just needs a LOT of sealing solutions to be found for the rotary slinding parts, especialy on the expansion since power is taken there, even with bad sealing it might perform well enuth

[@MyWasteOfTime]

How about using this as a generator for electric vehicles? 15KG could sit in your trunk but have plenty of power to charge your car on long trips! Heck make it portable so you can just put it in the truck for long trips!

[@mussie302]

I filed a patent application in the UK on this principle of engine in the early 80s, and I hawked it around every motor and engine manufacturer. The only ones who spent any serious time with it were Lotus. Suffice to say that nobody wanted to get financially involved, for all the reasons that you see in the comments here. I still kept all the original drawings but gave up on the concept as a nice idea which was never going to be practical in the real world. However, if these guys can pull it off, good luck to them.

[@thomascorbett2936]

I looks like it only has 2 moving parts, and those parts always go in the same direction , this is very good .

[@gothicpagan.666]

Sounds very exciting, one draw back that appears from the quoted No.'s is a lack of torque

[@mickmccrohon]

Good luck moving forward. The fluid running out of the Demo Engine is telling. Seals, seals, seals.

[@Milosz_Ostrow]

The narration in this video is syntax gibberish. it seems it written in a language other than English, run though a software translator and then read by a text-to-speech program.

[@geoffmcnew5863]

Having sold precision gear metering pumps, gerotor and lobe-style pumps, I'm pretty familiar with their limitations, and this motor is like a weird sorta 2-stage (high-speed) lobe pump. Low viscosity is a real problem for any positive displacement pump - an air/fuel mixture has none (no lubricity, either). I imagine that the internal clearances would have to be extremely tight, on the order of 1-2/10,000", and when you add thermal expansion (dissimilar on the two stages) to that, I'd expect it to seize-up. It might just seize-up on a cold day, too. Good luck Astron Aerospace.

[@RedSinter]

Very interesting 🤔. I like the idea put forth on the dual notch. The discussions on thermal issues, lubrication, matching tolerances all deserve being addressed and challenged to be proven right or wrong. The Basic concept seems workable as you say in many ways and areas. I'd certainly continue as someone said we rise to great heights by a winding staircase.

[@peeweeson]

saw the almost exact concept in a 1920's German engineering textbook but I hope that this concept gets its due credit

[@meekerdb]

Chrysler was years behind Rover. Rover built a gas turbine powered car, the JET 1, in 1949 and set the first speed record for gas turbine powered cars at 240 km/hr in 1952.

[@atsushi369jp7]

it seems very cool. over 80% efficiency and simple mechanics.

[@tonyho6211]

It's glad to hear this late gas engine be developed, but the point is how the thermal efficiency be greater than 35%. And by the way, can it be smaller and less vibration especially while starting it up? If so, it can be the generator for the power source of EV car in stead of dirty batteries! Hopefully, we can see the application of this engine to the public! It's my bottom of my Heart!

[@alanmenezes2666]

Outstanding idea, less moving parts, less fuel, more power. I'm not a mechanical engineer but you can cool down all types of engines. From the video the thing runs which is a plus I suppose, next step put a muffler on it and whack it in a car and see how it goes. Dont let the car companies buy you out, like the ceramic engine ( it doesn't need a cooling system). Also Ralph Sarich and his new engine from the eighties.

[@bombasticbuster9340]

IF, the efficiencies, process, and 80% thermal performance holds true; this is a significant breakthrough. Paired with a battery, this would be an incredible hybrid. Potentially doubling mpg. Its time to leave the 1800s timing chain, valve shafts, etc. I am impressed. I hope the unrealistic battery lobby does not destroy it.

[@Flapswgm]

I can see where I would question whether or not I would run 2 "notches" and not just one on the rotation allowing for a better combustion program. Also, I would also question the heat verses the cold section of the engine. It looks to me that one half of the unit will get extremely hot where the other will become very cold. This differential might cause a very bad expansion/contraction differential causing a warp in the engine as it gets hotter and hotter. What is leaking? Is that water or fuel?

[@D800Lover]

When I see the "destroy" word, I know that I see clickbait.

[@pistonhead05]

It is actually a really good design and compact, really good technology👏

[@mangeshsodnar8426]

Interesting.......can't wait to see it in production

[@jiml4826]

It’s twenty years away from market at best. All sizzle but no sausage at this stage. Best of luck guys.

[@sukmablack]

as a south east asian, i want to see this machine hooked up to a motorbike

[@larrycone8821]

I think it will work. It looks almost vibration free. Gearing/clutching may be a challenge as I am not sure about the torque curve. Hopefully it is flat. With an RPM range like that it sure would be fun to have on a motorcycle.

You know it's not a serious product when you hear those dings.

More simple more efficient and more reliable i hope so much we see these engines in cars soon

[@his18v2000]

Awesome design extra enhancement will make it more exciting

[@robertjongen7615]

Let us do the math for the Carnot efficiency : Typical Exhaust gas temperature at 700C = 1000K ( for a diesel it is lower) This means that the combustion temperature with a thermodynamical efficiency of 80% is 5000K The metal with the highest melting point is Tungsten: 3700K. So even if this engine was build out of Tungsten it will become liquid after a short time. There are simply no materials in the universe that can withstand these temperatures. Gas turbines are struggling to get an efficiency of more than 40% because of material limitations. Ceramic materials have similar melting points as tungsten but conduct heath not very well and cooling becomes problematic. Also if the combustion chamber has very hot walls this will worsten the filling and lower efficiency because you heat up the entering mixture. Tests with ceramic coated materials in engines gave no benefits and was abandoned a while ago. You will be nominated for the Nobel prize if you can achieve an thermodynamical efficiency of 80% with any type of combustion engine. Another factor that is not good for thermodynamical efficiency is a flat combustion chamber (e.g. Wankel engine). A flame front has a finite speed. To reach all corners of this flat combustion chamber takes time and not all fuel is burned. In other words the combustion will not be optimal. A Wankel engine therefor never can reach the efficiency of a piston engine. Ideally you want a compact semi -spherical combustion chamber were the flame front can travel from the center in all directions. This Omega engine has not an optimal combustion chamber.

[@mikemakuh5319]

Very interesting idea. What is the liquid leaking? More "sealing" problems?

[@indigenoussober407]

There are SO MANY small cars that would benefit greatly from this, not to mention all the Enthusiast Vehicles.

[@henryjohnjoseph2547]

Looks great. If it can beat the EV motor it should be an appropriate prospect.

[@bradmarkes1153]

Is the housing leaking oil and fuel? At what RPM does it produce 160HP? I love the concepts here and it does look lightweight with the hollow center. Maybe appropriate for a drone of some kind?

[@joeschlotthauer840]

This should be tested, and I'm offering my 1949 Studebaker truck as the "mule"

[@wornoutwasd8567]

I've seen videos on this for more than a year now but no working prototype. This engine requires magic ring seals that don't exist and won't keep compression.

[@timothyfalkowski6007]

my new rotary engine design is use a pair of roots/screw type compressor, then the combustion chamber with direct fuel injection and glow plug, then a second roots/screw compressor to turn the expansion of the combustion into rotary motion and power to drive the intake compressor and the output shaft.. frank whittles first jet engine was a turbo like use in piston engines, except the pistons were eliminated. turbines have pressure slippage/lose, a roots/screw compressor is positive displacement.

[@zeejimi4044]

Nice idea and development, but as some people say when they want proof „Put up, or shutup !“..😊

[@tomsullivan8040]

I worked a factory to produce the rotary engine, There were too many tolerances to me met so it was cancelled. We should also be concerned about air consumption. A normal 3 liter piston engine consumes as much air as 15,000 people. How much will this consume? Imagine China and India wiht cars powered by these engines. Remember our atmosphere is a thin layer around the planet , like the onion skin on an onion. I like the weight reduction. If we put $100 worth of gas in a 4000 pound car $95 goes to move the car, $5 to move the 200 passenger.
