A lot of people are missing the point in the comments. Yes adding a gas turbine adds weight and loses in efficiency. The strenght of such a design is decoupling the design constrains of a jet engine. Generally the higher one flyes the less drag but one needs to also fly faster to maintain lift. Problem is traditional jet engines stall out because they cant work well at low and high speeds. Think of it this way. You can fly at mach 1 and have X amount of drag thus needing X trust. Or you could fly at mach 3 but higher where the air is 9x thinner so again you only need X trust but now for only 1/3 of the time to reach your destination. But making an engine that is high power at mach 3 and doesnt blow up on take off at sea level is a rather difficult task. Now these guys are very very far away from making it work, but the concept is rational and plausible. The just wanna make a ramjet optimised for mach 3 and add an electic motor for getting up to speed and altitude.

[@SlayerBG93]

@@JoeyBlogs007 that is also a factor. In my above example that aircraft would be taking in 1/3 the oxygen since 3x speed at 1/9 air pressure. So it would have 1/3 the power but would need to maintain X thrust.

[@MrRobertX70]

And how do you think the generator-turbine will work with no air?

[@williamthornton5856]

Your right in that in the 3rd part of operation, it becomes a ramjet. However, the electric intake fan is completely bypassed at that point. Litterally no longer in use for any propulsion. The hard part is the 2nd mid section partial burn, where the burning mid section both provides aft thrust and generates power for an electric motor to spin the front fan. These two things work together upto near mach 1, but when going transonic, the fan will need a variable intake and bypass cone like the SR 71 had as its speed increases until the intake fan isn't providing thrust and can be bypassed. Also managing the shockwave, they must somehow heat the front fan section up with burning methane or bypass and direct the schockwave to the methane burning mid section and slow it to just under mach 1, which is around 1,500 mph at 1000 deg C . Methane or jet fuel is used to get the aircraft beyond 1.5-2.0 mach so that the ram effect using the afterburner can start. A problem not mentioned is Electric motors have horse power deficit limitations compared to a turbine engine which turns the front fan for low speed thrust. There are no 50,000 horse power electric motors that are light. In fact, there are NO 50,000+ hp electric motors period, whIch is what the front fan section on each engine on a supersonic airliner would need. The closest thing is 2,400 hp electric traction motors which rail road locomotives use (usually 2 to 4 per locomotive) These are beefy and too heavy for aviation use. Plus R.R. electric motors are simply not powerful enough. So there's that. Ramjets similar in design to the SR 71 used when the front fan and turbojet center section is bypassed, have mach 5 speed capability. But ironically, right now, the show stopper is the complete lack of a lightweight 50,000 horse power electric motor to go from a stop to about mach 0.8. I also fail to see why even if the was a 50,000 hp electric motor to turn the front section, even at 95% effeciency, a standard turbine section mechanically driving front fan blades would be more effecient than a turbine turning a generator to make electric power for a 50,000 hp electric motor that does not exist. At least at over mach 0.5 or so. A turbine generator set up would be more effecient with less fuel usage at idle, and low economy power, but not when pushing past mach 0.7 and into the mach 0.9 to mach 1.2 transonic range.

using a gas turbine to generate electricity to power electric motors is adding cost, complexity and inefficiencies and is an absolute non starter. This is high grade snake oil. Motors and turbines aren't the problem, it's fuel/battery/energy density/weight that is the issue and this is more inefficient and more weight than current jets. If you really want an electric jet with current tech the only real answer is an unshielded nuclear reactor that will seriously harm all passengers.(yes that's been done before too). The reason why commercial planes don't go supersonic is because air resistance drives fuel costs up, going faster just costs a lot more.

[@jonahshill7084]

@@uIz_slc it’s a bit long winded so I’ll just list. Hopefully my reply isn’t not too long. if it is here is the jist of it: ** the Concord program was shut down because of high fuel costs, high maintenance costs, small passenger capacity, limited market (flight route limitations and narrow customer base because of costs) and poor emissions. the idea that is proposed here has not addressed any of these.actually, it seems like this idea only makes these issues bigger. 1) assuming they manage to achieve the same efficiency for combustion as conventional engines, they would have compounded losses due to energy conversion (mechanical to electrical for the generator, electrical to mechanical for both motors). So assuming 60% combustion efficiency and 95% conversion efficiency you would have 60% x 95% (mech to elec) x 95% (elec to mech) = 54.15% overall efficiency. If you already had 60% efficiency without electrification, you lose 5.85% efficiency for no reason 2) even if electrification could save you 2 tons of fuel taxiing (compared to Concord), the losses in efficiency over long distances costs you more. Currently, supersonic air travel is banned over land because the sonic boom was so disruptive to people on the ground. And supersonic air travel doesn’t really have major benefits over short flights ie going twice as fast for a 60 minute flight could reduce travel by 30 minutes, but the cost of the tickets and higher maintenance costs wouldn’t really be worth the 30 minute benefit. So longer flights would have to be the operating territory. Over longer flights, taxiing losses make up a smaller and smaller percentage of fuel consumption. So if conventional planes are 5% more efficient in the air over a flight that consumes 100 tons of fuel they save 5 tons of fuel. This offsets taxiing losses by at least 3 tons (keeping in mind that 2 tons of taxiing losses is the losses for concord, not current planes, so that difference might be even bigger). so their design is inherently less efficient. 3) he claims that using liquid natural gasses generated using carbon dioxide extracted from the atmosphere will be the solution. Carbon dioxide makes up less than 0.1% of the atmosphere. The energy needed to sift through enough air to suck up 1kg of CO2 would be way more efficiently used by generating biofuels. beyond this, the energy efficiency of convert carbon dioxide into ethanol (which is way to volatile for planes to use) is currently 50% at the absolute maximum (typical values are 35%). to get less volatile, more usable fuels, the energy efficiency would be even worse. considering the amount of fuel need to operate at supersonic speeds, the production of infrastructure (CO2 capture, catalysts, renewable energy infrastructure, other reactants needed for the conversion, etc.), and infrastructure maintenance the overall energy consumption would be likely far surpass that of conventional planes. 4) synthetic fuels are EXPENSIVE, and the air travel industry is famously reliant on fuel prices to remain even slightly profitable. supersonic air travel requires more fuel to maintain their speed due to drag, so their planes would consume far more fuel, especially over long distances. 6) most people won’t be willing to pay a price which is exorbitantly high just to get to where they are going a few hour quicker. Especially if that same money could be spend getting first class tickets and better accommodation if spend on conventional planes. 7) weight and space are at a premium on planes. This systems effectively requires the space and weight of 3 engines to get the power output of a maximum of 2 engines. because of the added auxiliaries needed to operate the generators and motors the weight and space requirements might mean more energy even greater fuel requirements, while being able to transport fewer people. now, the Concord could carry a maximum of 128 passengers over 3 500 miles, using 94 000 litres of fuel. a Boeing 747-400 can also travel 3 500 miles while consuming 94 000 litres of fuel, but it can carry 500 passengers. even assuming that this guys company can come up with an engine design 50% more efficient than Concord that uses up half the space and weight so that the place can carry twice as many people, you would only be able to carry 384 passengers (128 *1.5 *2). I know it's a simplified calculation but the point is that the CO2 economies dont make sense, and the ticket prices would be outrageously high because all those aded costs cant be distributed across as many people. 8) the additional drag induced by having 3 engine inlets instead of 2 at supersonic speeds mean the fuel efficiency ‘gains’ they claim are nullified. one intake would be required for the generator unit. it would be inefficient to funnel the air from the generator unit to the motor-driven engines becuase, the a lot the kinetic energy of that air has been converted to electrical energy and that air is oxygen depleted because of the combustion in the generator unit. so you would waste energy speeding up that air, and you would have incomplete combustion in the motor-driven engines because of the lack of oxygen. so you would need additional air inlets for each of the motor-driven engines. even for a platform with the same number of inlets, the percentage increase in drag from 300 m/s (conventional plane speeds) to mach 1.5 is about 70-80% more drag. they want to operate at mach 2, which would result in drag increases of about 200-400% because drag increases with the square of speed and there are near exponential losses induced due to shock wave formation. at supersonic speeds, engine inlets contribute to about 20-30% of the aerodynamic losses of the plane. so the additional drag increase at mach 2 would be 240-520% increase because of the 3rd inlet. 9) the volume taken up per unit energy of liquid natural gas is far less than jet fuel. This means a lot more space is needed to store the same amount of energy. because drag is a function of the frontal area of the plane, this would only further increase the drag. if the plane was made longer to avoid increasing the frontal area, there would be added skin friction because of the increased surface area of the plane. so you could add another (conservative) 5-10% loss in efficiency. 10) the additional weight and complexity introduced because of the need to contain liquid natural gas in pressurized vessels, would require more fuel, which needs bigger, heavier pressure vessels, which adds weight, which needs more fuel to transport, etc. so that is yet another loss in efficiency.

[@ArinzePaul-qw7hq]

Love your idea bro❤ good luck 👊

[@makex_se]

So the turbine is replaced with a electric motor. This electric motor then gets electricity from a gas turbine generator. Where do you gain efficiency? If I guess its because a single gas turbine can run at max efficiency and power multiple electric motors. The Electric jet engines then are more efficient because no rotor is blocking the exhaust. Am i understanding this correctly? Love it, very cool!

[@Quatuux]

The best land-based combined cycle gas turbines reach only 55% efficiency. I think you're correct, there are no efficiency gains but instead huge losses with this concept. A conventional turbine has an efficiency of 90+ %.

[@Quatuux]

I don't think that it's more fuel efficient. A 90+% efficiency turbine is being replaced by a gas turbine that has at most a 55% efficiency, which then loses energy in the alternator, electronics, batteries and finally the electric motors that drive the compressor? Am I correct or did I miss something? About being able to fly at both subsonic, supersonic and hypersonic speeds, you just need a turbojet and a dual-mode ramjet in two different ducts. Check the SR-72 concept from Lockheed.

[@gasun1274]

It's fuel efficient in the sense that losses are reduced in flight because the compressor stage can be turned off. Conventional engines cannot stop the compressor when the air velocity is high enough that it doesnt require a compressor anymore. As for the SR-72, that is a less viable solution for commercial flight. This electric hybrid turbojet should have less moving parts to work.

[@Quatuux]

@gasun1274 I disagree. The SR-72 concept with two ducts is much more efficient and cost effective imo.

[@NeilStansbury]

Yep you did. Gas turbines are very efficient, but most efficient in a very small RPM range. By designing a fixed RPM gas turbine running on methane to generate electricity, which then powers an electric motor without those flaws, you end up with a fuel source that has the energy density of hydrocarbons but the efficiency of battery power. Once the airflow is supersonic it then bypasses the entire compressor stage and converts into a pure ramjet (which isn't novel in itself), except now you don't have to restart the 1st stage compressor when it slows to subsonic, because its electric you just turn the power back on and spin it back up. Effectively what they have done is create an inverted high bypass electric ducted fan with an afterburner on the back.

[@Quatuux]

@NeilStansbury you did not answer the question. How does replacing a turbine stage that has a 90+% efficiency with a gas turbibe that has a 55-% efficiency to drive the compressor would increase the overall efficiency? 😂

[@NeilStansbury]

@@Quatuux ​I think you've misunderstood what they have done - it wasn't brilliantly explained in the video. A "Gas Turbine" is made of 3 parts - compressor, combustion chamber, turbine - their collective efficiency is based on a ton of factors, from compressor ratios, no. of shafts, air density & temperature (eg. altitude), speed etc etc. Aircraft also have the advantage of being able to use the "ram effect". These guys have taken a variable RPM "gas turbine" and made it a *fixed* RPM gas turbine that is used to generate electricity rather than accelerate air (as in a normal A/C engine). In other words the turbine stage is *still* there, it just runs continually at an optimal RPM, one (or all) of the turbine shafts are connected to a generator. The electricity is used to spin what is effectively a multi-stage ducted fan. Have a read up on the Rolls Royce E-Fan, RR thought it would be at least 10% more efficient

But they decided to use this thought process to its logical limit if you can use mechanical energy to generate electrical energy maybe you could spool the turbine at faster speeds without needing heat. That’s the problem with turbines to get greater efficiency you need higher rpm which means you need to get the combustion gas very hot. Hot turbines melt warp and fail. So just use an electric compressor down stream. Of course I’m not a aero engineer but this is my general take away from their video.

trains have this peculiar characteristic that the heavier they are, the better they are... they rely on weight to get traction. steel wheels on steel tracks. and once moving, they continue rolling with very little effort... when kept below certain speeds and air resistance is negligible. tracks are arranged to be as flat and level as possible. as accelerating is the only part that really requires power, and is based on the rate of acceleration, you can get away with a limited amount of power moving extremely large amounts of weight around, and the payload is barely affected by the source of motive power. then once moving, those diesel engines can be backed right off to just a bit above idle, where they run on barely any fuel at all. so the cost of moving stuff around is rather minimal. its also really easy to plug in cables and distribute that power along multiple sets of driving wheels. no driveshafts, no special couplings or joints or bearings or gearboxes... any other vehicle? the weight of the source of power, versus the payload starts to become a problem. planes need to be LIGHT. as light as possible. any extra weight detracts from their ability to stay airborne, and retain their primary function... move many people large distances rapidly as cheaply as possible. cars and trucks have to deal with varying gradients, and carry as much payload as possible... they have to factor in tyre wear, suspension systems, road construction and weight bearing ability... and once you go over a certain speed, air resistance becomes an absolute killer. i am not even going to touch on hydrogen other than its more wishful thinking. go make a few phone calls to local industrial gas suppliers, ask for some quotes on hydrogen. then look at how the hydrogen is stored. the wight of the bottle, and the size of it. then run through the basic maths on how much energy you will get from a certain volume of hydrogen when consumed in an ICE. hint, a 2L engine at 3000RPM will need somewhere around 20L of hydrogen every SECOND, assuming full throttle and 100% VE. i calculated around about 7minutes of run time from an F size bottle, assuming "cruising" travel...

[@TheWizardGamez]

hydrogen combustion engine is a futile effort. just run a fuel cell.

[@jameskelly8506]

No matter what powers an aircraft, you still have to deal with the super sonic footprint. That's the main reason Concord traveled over water. Mach 3 is another matter, heat!

[@williamthornton5856]

@@jameskelly8506 Now the sonic boom can be changed to a much quieter drawn out "thruummmphe" without out the window rattling sudden pressure wave. Google "X 59 no sonic boom". However, the show stopper is NO LONGER a sonic boom, but the much, MUCH higher cost of buildong, operating and maintaining a fleet of supersonic airliners, (as it always has been)even with the old sonic boom issue.

[@wovasteengova]

Astro how do you plan on cooling the motor(s)?

[@i3_13]

They didn't mention the thrust. It would be nice if we could compare to the raptor.

[@yaad2226]

if i have thought of this engine 5 years ago during padamic i am sure many have done so

[@danvasii9884]

Congratulations! First marshmallow supersonically tested...., sorry, toasted!

[@astro1322]

So are they using only one motor to spin the compressor. Or are they using multiple electric motors to spin different parts of the compressor?

[@geonerd]

This just SCREAMS "INVESTMENT FRAUD!!"

[@BasedF-15Pilot]

They have the right idea, but they're trying to shoehorn electric driven compressors for some reason. I blame the fact that the electric motors are probably investor bait right now. Here is free consulting from someone with a lot of supersonic experience: Toss all your ideas of electric driven compressors in the garbage. Start with a Concord. Add 6 ramjets between the traditional low-bypass afterburning turbofan nacelles. Add hydraulic variable ramps that block the ramjet inlets at subsonic speeds and when accelerating to speed, and variable inlets/ramps that block the turbofans at supersonic+ speeds. In flight, swap to ramjets at mach 1.5-2.0 or so. Turn off turbofans, block inlets with ramps. Cruise at mach 2.5-3.2 or so, metallurgy dependent. On decel back to subsonic speeds, turn on turbofans, cut fuel to ramjets. If you try and turn a compressor fan into a ramjet you're just going to compound energy loss with both the electric motors and the compressor blades interrupting the supersonic compression of inlet air at supersonic speeds.

[@feluke8396]

Okay, when the opening has to use the line “environmentally friendly” along side the tech, I have my doubts. Make and promote the product, make it work THEN use the EF aspect as a BONUS of the technology

You need an open yoke, especially for supersonic.

It’s gonna be hard to figure out how to stop the sound barrier from exploding above everybody’s heads😂

[@aterxter3437]

You are just using a frigging jet engine (a gas turbine is just a jet angine with more turbine stages) to run EDFs with an afterburner. In essence you are using a jet engine to run a bigger compressor, that works with an afterburner. You are just physicaly separating the components of a fighter's turbofan engine (take the snecma m88, most of the thrust come from the turbofan part). You have one point : as a jet engine only works efficiently at certain thrust/speed/altitude points, it COULD be more efficient when changing altitude, but it's pointless during level flight

[@larslrs7234]

Cheap electric supersonic flight carbon free, just like warp drive. I love those new sci-fi channels. They present stuff as if it was real or possible.

[@GenX-jedi]

just two small problems that Concorde had, how loud the engines will be and the sonic boom, will be no quieter. This is why Concorde only flew over the atlantic after test flights over the USAS , Europe and asia, the complaints about the sonic boom stopped flights east or south from heathrow and Paris.

[@crhonda500]

Yes this is the way of the future 3ph motor will get the RPMs hope you did patents ?

[@peteregan3862]

Boom is flying at M1.7 (1800kmh, 500m/s) due to aero-heating issues and energy use. M3.05 (900m/s, 3240 kmh) is for military, government applications at present, perhaps also the business aircraft market.

[@supabursche]

Why is it a good idea?!? Because it solves many issues with current engines in such a simple way that i go like "Daaa, why has nobody thought of that before🤦"

[@paradiselost9946]

people have thought of it before. and they knew it was an exercise in futility as did their investors. but now we have generations of utter idiots with no knowledge of how anything works, fed a diet of hype and keywords and kindergarten level explanations of how things work...

[@TheWizardGamez]

as they stated, electric motors have been massive and heavy for a while. trains run on electric motors but trains also dont fly(hopefully). the catalyst here is electric motor innovation. it is to be seen if this works. I hope it does

[@evanbarnes9984]

I would honestly much prefer SF to LA in 3 hours on rail so I could visit my nieces more easily.

[@thorns17]

Reading a few of the comments, I am surprised no one mentioned the sonic boom. Having the engine is one aspect, but getting the regulations to fly over population centers is another. Don't get me wrong, this is great, ( no pun intended ) but I wonder if this will get off the ground

[@ericswain4177]

So who is funding this project? Great idea, The affordable part is a pipe dream many brilliant people have come up with wonderful innovations, ideas, and inventions to make something or life more affordable, easier, etc.. but sadly this is rarely the case. Good luck guys.

Can the engine be used to produce electricity?

Yes it's a full set Generator set by design.

[@Mallchad]

Yes, all aircraft engines produce electricity by design to supply the aircraft with power. Only the aircraft, if you're thinking of ground use its pointless because you're wasting energy by dumping it off the side and not allowing it to build higher pressure.

It sounds like he's talking about the basic diesel electric hybrid technology that's been used in the train industry since mid 20th century.

[@HansMilling]

Jet fuel is designed to be not so easily flammable. Where methane is very flammable. So in case of a crash, planes with that jet engine will explode in a huge fireball.

[@maximilianschutze4565]

How about the generator? Still extra weight and complexity

[@nighthawk0077]

Man that electric motor and compressor scream at 30%. Need to quiet that down by a lot. Perhaps using newer style fan blades?

[@stadtaff1860]

8:10 where is the electric part in these 3 stages? Looks like a normal jet engine. Or is it the spinning in the first stage done by the electric motor?

[@recoilrob324]

The power needed to spin an axial compressor hard enough to feed an actual jet engine has to come from the turbine making the engine self sustaining. Powering a generator to then power the electric motor just adds a lot of weight and complexity and parasitic losses. This is just another effort to make it look like you're breaking 'new ground' to attract unsophisticated investors while not having the slightest chance of ever working out as hoped. "Oh well...we tried" after working for years while burning other people's money.
