Never thought I'd enjoy this, but I've had my eyes opened.

[@Nightlurk]

Damn batteries, WHY ARE YOU HOLDING US BACK?!!

[@knowledgeispower88]

hahaha

[@RealistReviewer]

We have dozens of better battery designs, the problem is no one is making them yet, however the Chinese are working towards getting some of these idea's going. At least they are prepared to take risks and invest in new technology we need to power the future. The most exciting development was the salt treating the electrodes in dry lithium batteries as it doesen't cost very much to improve batteries that are quite easy to make, but wether the West will manufacture them is debatable... again the West lately has been lagging behind in battery tech etc. it's almost as if it's being suppressed by large corporations who's interest is in fossil fuels..

[@deathpony698]

bruh, lithium-air

[@Razyre]

Technology is just generally pretty shit. There have been big advances in improving life cycle of Li On, in fact it could come out tomorrow at this point I think, lots of companies have massively increased the life of Lithium cells. Actually getting higher density is fucking difficult. You can get higher density pretty easily in a non rechargeable cell, or a cell that can be recharged a few times, but you have dentritic formation and all sorts of other horrible stuff to worry about. Extended Li On, Lithium Air and Sodium Ion are the three I'm most interested in. Li On that lasts longer is nice in devices like EVs where they are charged and discharged a lot. Lithium Air is insanely light and has a very good theoretical density but the best designs at the moment require pure oxygen for cycling and also charge/discharge very slowly AND have dendritic formation which means potentially "boom boom", an issue Li On had in the 1980s. Sodium Ion is close to commercialisation if I understand correctly, with an energy density similar to Lithium Ion at its inception, perhaps close to Lithium Iron Phosphate as it stands today, but it may be very, very cheap. So if the technology gets developed to the level that Lithium Ion has been for density, then it could mean identical energy density for way, way lower costs because Sodium is so abundant. And we can already make 300+ mile cars on Lithium Ion, it's just expensive. As for aircraft? I don't know how feasible long flights are in a plane carrying batteries. I guess the bigger the wings, the more weight it can take, but of course airlines want the most passengers possible and you're going to need an insane charging infrastructure to charge big airliners. I have a feeling aircraft will stay hydrorcarbon for a long time, BUT, imagine it just being aircraft spewing fumes while everything on the ground is electric. That will really, really help the issue.

[@NicholasMarkovich]

Whoever patents the next generation battery with very dense power storage capable of taking a high current for fast charging but relatively cheap manufacturing costs, stands to make a fuck tonne of money.

taking range anxiety to a whole new level

[@RealistReviewer]

Hence the parachute.

[@R3Cat]

at least you can glide quite effectively in an airplane after your engine shuts off. A boeing 737 can glide for 100 miles with it's engines completely shut off!

[@kevinscales]

Depending on altitude of course

[@ThomasMTube]

+Re these racing planes drop like a brick apparently.

[@JoshWeaverRC]

Comforting to plane ahead when you are going to be using a parachute.

[@SWR112]

Small projects like this deserve medals, taking the tech further and being brave enough to do it. Old fashioned men in a shed mentality of we can do it. Very British it has to be said. It's guy like that these that won the war for us. 👍

[@RealistReviewer]

Small scale innovates and then we can scale it up, indeed we need to encourage small innovators, surely the larger manufacturers are moving far too slow.

[@DrWhom]

Yup, and it's the cocks the read Politics & Philosophy at Oxford who will make sure it never becomes an industry...

[@herbertshallcross9775]

It doesn't actually. At least the Siemens Extra 330 electric plane uses a new motor design. This is just pretty much off the shelf stuff. It's an experiment into whether there is still a sucker born every minute ,and Rolls Royce has confirmed it.

[@davidhalevi]

You mean American men that won the war for you.

[@davidhalevi]

I agree with you completely. FDR was by no means a good man.

[@johnbenton4488]

I've just modified the design of my 'light' 4-seater. Thanks Robert for bringing this astonishing bit of kit to my attention.

[@TilmanBaumann]

As a RC pilot I'm not surprised at all. The instant power you can get is absolutely nuts. People are launching huge +10kg gliders to several hundreds of metres within seconds. (We are talking ~100A at 50V or thereabouts) Or if you want to see something really terrifying then search youtube for F5D hotliners. (edit: fixed typo)

[@toyotaprius79]

Daamn

[@N221BP]

That's actually F5D Hotliners

[@TilmanBaumann]

N221BP absolutely correct. I must have hit the wrong key on the mobile keyboard.

[@brokenacoustic]

Things dont always scale up or down the way we think they will though...power to weight and battery performance drops once you start getting bigger and heavier. It'll happen eventually, we just need the next battery technology, something that makes lipos look like NiCD.

[@awuma]

Three hour duration, 13,000 ft altitude and 100 km radius of operation is not unheard of for electric UAV's. Look up "Gemini V-2" for a good example here on KZbin; this craft is designed for stable load carrying and not speed or efficiency. This fellow makes and sells his own battery packs based on how Tesla do it. All of the equipment to home build and fly such an aircraft can be obtained by anybody.

[@fusionmarklittle]

Best video I have seen for a long time. Not into planes that much but after watching this I feel I could be! More videos with beautiful demonstrations like this in the world please! Excellent work Fully Charged!

[@WolumoDK]

[@nelsondisalvatore9812]

there wouldn't be enough content for a weekly show, even here in KZbin there is a few hiccups of 2 or 3 weeks without a significant video

[@rckeith]

Great episode. I'm a model aircraft builder and flyer and electric in the last few years it's as completely revolutionised our hobby. We know have models we could only dream off due to costs. It's also bringing in people to the hobby because the cost and ease of electric flight. We very rarely now get a beginner flying with the old 2 stroke engines. Just look at the rise of the drones. That's only possible due to the advancement in batteries and brushless motors. The only issue with contra rotating props is noise. The Russians Tu95 or the Bear has its know, the ones Putin keeps probing our airspace with , is one of the noises aircraft in the sky especially at take off and landing.

[@rickmurray7123]

Tu95 also has its props running at supersonic tip speeds which when you have 8 props must be incredibly noisy.

[@CalebT_RC]

When the power goes up on the motors, it sounds so evil and powerful

[@achim.t]

This might well be my all-time favorite episode!

[@ThickeyUK]

I loved this, great topic and everyone seem genuinely excited and enthusiastic about the project. Beautifully shot and edited.

[@herbertshallcross9775]

"everyone seem genuinely excited and enthusiastic about the project" Why? It pains me to see people gush over rubbish, but to quote the title of a W.C.Fields movie "There's a Sucker Born every Minute". The aircraft has flown. It reached it's very modest design goals, of flying a little over 300 mph for about ten minutes. in the 1950's airliners were in regular transatlantic service that cruised as fast as that. This aircraft has no potential to be nothing but pointless. By shaving away anything that isn't essential and sacrificing any flight endurance at all, they have managed to reach speeds ICE aircraft attained in the early 1930's, but even those aircraft had much better flight endurance. A 90 year-long giant step backwards.

[@khuramzahid]

[@bobi2582]

I've been flying Electric powered model aircraft for years now using 3 phase brushless motors and Lithium Polymer Batteries. This combination has revolutionised the radio controlled model aircraft scene and has helped with the development of all modern electric vehicles. The model motors produce huge torque and high power and some models can be as large as 50% of the real full size aircraft. Many modelers prefer this method of propulsion over Petrol or Nitro/Diesel because of the reliability and adaptability with the benefits of clean, quiet flight.

[@KURTrek]

300 horse power!? For that little thingy!? Amazing, kickass, awesome, sweet, FANTASTIC!! Thanks robert, one of the coolest videos yet!

[@OneWildTurkey]

300 miles per hour, not horsepower

[@flybobbie1449]

So could potentially fly at lot longer at lower speeds. Say half hour at 100mph.

[@sonnymoon6465]

[@pldilosa]

Absolutely FANTASTIC !!! Both Show and Material

[@RedBearAK]

It's very impressive that they've integrated a ballistic parachute into the airframe. They still aren't widely used, but every small plane should have one in my opinion.

[@RealistReviewer]

No reason not to.. just cost, but saving lives is worth it!

[@helphelpimbeingrepressed9347]

It has cost benefits too, you get to recover the airframe.

[@MomentousGaming]

It does cost a lot and has to be designed from the start. My argument against it would be that aircraft are already very safe, and by adding this large price increase you will reduce the market. A 30 year old Cessna will cost you $40,000

[@deathpony698]

idk what your talking about, all my planes in kerbal space program use it.

[@operationscomputer1478]

This is probably the video I have enjoyed most on Fully charged - so nice to see an interview with four really talented engineers who are also very good at explaining concepts in such easy to understand terms. - The national grid one was also very enjoyable, for the same reason. Really good episode Robert.

[@paulmichaelfreedman8334]

1 word. WOW. Thank you Bob for this one. This might shake up the commercial airline industry within a couple of years. I'd like to see that, like the automotive industry is now undergoing a revolution.

[@herbertshallcross9775]

Piston engines were almost completely abandoned by commercial aviation fifty years ago, and no electric aircraft has the promise of being able to match piston engine aircraft's speed, range, or passenger and load carrying capacity of fifty years ago, let alone giving turbo fan aircraft any competition at all. Maybe in the 22nd Century. Maybe.

[@indian1889]

robert that was more than awesome .... :)

[@keithfreeman5204]

Suggestion....Put the props in a aerodynamic duct. Eliminating the wing tip vortex (s) from the prop tips will increase efficiency about 27%. I design, build, and fly Radio Controlled aircraft. My love of flying started back in 1959. In '76 picked up my first 5 channel radio, been flying R/C ever since. I am 65 now. Currently working with Blended Lifting Bodies, Delta Wings. Very low drag.

[@ianabruce]

That's what I was thinking... You could easily mount a duct on the test rig. Also, how are they measuring combined thrust with 2 separate thrust stands? Does the base have its own load cell?.. Or is it as simple as combining the 2 thrust stand numbers?

[@terryhollands2794]

I hope they are able to achieve their dreams.

[@markouniversalis6941]

[@richbuilds_com]

Can't wait to see that flying! :-)

[@johnbenton4488]

Being a bit on the picky side, and being trained by the RAF in the trade of propulsion fitter (the highest technical training available) Please note the difference between contra-rotation (one ening and a gearbox) and counter-rotation (two engines working independently of one another. Hence the a/c has counter-rotating propellers. Also, the 'mixture' on light a/c is manual whereas on larger a/c the mixture is altered automatically by the fuelling system (Either the carburettor, or the fuel-injection system). Just small points but aid accuracy. Sorry to bore you.

[@fullychargedshow]

Not boring, especially the difference between contra-rotation and counter-rotation. I will inform the team. Thanks.

[@johnbenton4488]

My pleasure. It's just that I do not like to appear a smartarse.

[@ThalassTKynn]

You are correct, though the larger planes tend to have variable pitch propellers too, so you still end up with several levers per engine. That's why I prefer jets or electric. One lever per engine/motor. :P

[@johnbenton4488]

An excellent point. Fewer levers = less complication and lower weight.

[@PistonAvatarGuy]

Piston engines can (and should) be single lever controlled with a FADEC system.

Sure, but this thing doesn't actually advance any technology. They bought the lithium cells off the shelf. The motors, propellors, battery protection and speed controls are probably hand made, but they are derived from quite conventional existing technology.

[@pogo1140]

What's interesting about a technology that was abandoned in the 1950's There is only one production airplane that I know off that uses that setup today, the Tu-95 Bear and the AN-22, and both used tubo-props and there hasn't been a new version of those in 50 years.

This is not progress. it is a giant step backwards. Rolls Royce has an enormous engineering department that will spend zero time working on this project. The cooperative relationship is almost certainly limited to Rolls Royce's advertising department. Rolls Royce's products have a major carbon problem, injecting enormous amounts of CO2 into the sensitive upper atmosphere. This is Rolls Royce tying to distract greenies who think electric aircraft will ever be more than a gimmick from their core products.

With electric aircraft, we get to relive the early 20th century. I can't wait until we have a Lindberg moment when someone flies an electric airplane across the Atlantic!

[@JoshWeaverRC]

Michael Harmon. I feel the same for RC aircraft. Too bad some of it is about weaponizing them. Silly people and war push the technology as well as hold us back on using the full potential of it. If we actually focused on it there is no reason why we could not have an integrated flight path for humans in flight via pilotless systems. Step into a pod, choose destination, and step out. depending on distance it flies in most efficient form.

[@gregorydodwell3895]

On a geeky historical note, a more elegant late Spitfire example would have been the Seafire F Mk47, as it sported contra props in addition to the enlarged control surfaces etc. Loved the enthusiasm of the team and the points about torque, temperature and O2 requirements. Can't wait to see it fly.

[@foe11191969]

I believe that Robert should do a follow-up on some of these startups/shows. I think that WE'd all love to hear about any progress or lack thereof. At least the cold, hard facts about companies/products that didn't quite make it. I'm an electric car owner and am going "greener" by the day, but would like some updates on his older shows. Been watching for years...and CHEERS.

[@Gribbo9999]

I think a key point made was that propeller aircraft technology became "parked" for a few decades because of jet engine development. Electric motor and battery technology has the potential take propeller or fan technology to the next step.

[@RealistReviewer]

So much potential it's revolutionary.

[@Skracken]

Propellers don't really work at the speeds that airliners or fighter jets fly at. For those you'd have to use a ducted fan if you want to go electric. Actually modern airliners already have ducted fans, it's just that a jet engine drives the fan, which produces most of the thrust, while the jet engine exhaust provides only a fraction of the thrust. So if you had a powerful enough electric motor you could power the fan with that instead.

[@RealistReviewer]

Skräcken Russia has large prop bombers that can fly at least 550mph (some clocked faster) the same speed as the average air liner, they are large prop craft which carry very heavy loads at some very high altitudes, there is no reason why you wouldn't use them in a hybrid system, it just wouldn't be super fast, but nor is the average air liner.

[@Skracken]

Indeed so, but it's at the extreme end of what props can do, and it's also one of the loudest airplanes ever made. The americans tried to make a supersonic propeller fighter too, but it simply didn't work. And that one was so loud it actually made the ground crew sick and some even became unconscious.

[@RealistReviewer]

Skräcken Electric engines are quieter even with a prop, we also have quieter prob designs nowadays, you would be using generators to power the electric engines (in a hybrid system), there would be a significant drop in noise compared to old soviet bombers... I think also that it would be possible to use solar panels to get some power back also, lots of possibilities there.

[@greyareaRK1]

Loved that. Eventually, electric power will completely transform the designs of planes, as it has already demonstrated the capacity to do for land vehicles (though sadly there are few original ideas that have made it beyond concept designs). A tangential suggestion to this episode: have a look at drone racing.

That's because electric motors are 2 strokes, they are an electromagnetic form of 2 stroke with high power and few parts. Also lightning bolts are 2 stroke because they fire down a streamer and up a return stroke sometimes it can go the other way, but its one of the most powerful and energetic 2 strokes known!

[@herbertshallcross9775]

No it's not! This thing does nothing to advance battery chemistry, electric motor design, aerodynamics or pretty much anything else. There are battery powered light sport aircraft, and they all share one feature. Anything they do has been done better long ago by internal combustion powered aircraft. There are probably more four to six seat aircraft that can fly better than 100 mph for hundreds of miles, and with an instrument rated pilot do the same in all but the most severe weather than any other class of aircraft, but so far there isn't a single electric aircraft in that category because electric power systems do not produce enough kilowatt hours, and no battery chemistry that is threatening to go into production in the next decade can .

I worked in RC developing lithium batteries and motors around 10 years ago when it was a really exciting time with new technologies, as a commercial pilot now I can see so many advantages to what these guys are doing. As a light aircraft introducing a level of redundancy (assuming it can climb on a single motor) is so innovative. Superb stuff, I can't wait to see what they do in the future

[@herbertshallcross9775]

Latest iteration of the design seems to abandon the CR props, instead using three electric motors coupled end to end .

[@AdrianoCasemiro]

High power is easy, just look at the model flying community, they've been doing just that for years. The hard part is a long range electric plane.

An overunity motor generator could be used like john Searl magnetic motor generator or a Witts generator.

[@xxdeserthunterxx2819]

Seriously, never heard of contra-rotating propellers?

[@wtfrofllolxd]

the Production quality of this channel is amazing, I hope more and more people come and watch!

[@1981dasimpson]

that was impresive and beautiful looking aircraft

Model of a proposed aircraft. What you see in the video is not intended to fly.

[@KenHeslip]

Good to see haters of this video are in the vast minority.

[@RealistReviewer]

I think most people want to see us trying new things and EV's are part of this, it is only a certain amount that is dependent on the fossil fuel industry that is trying to hold it back, one of those ways being negativity towards EV's. But Fossil fuels is the tech of yesterday, we cannot use it forever, EV's you can!

Ken Heslip The word is stark, not vast

[@herbertshallcross9775]

Because it's so much better to gawp and say "Gee Whiz!" than to actually understand.

[@Miata822]

Fascinating. But will it regen when coming back down? On a serious note, i could see this technology being used in a hybrid system on a fuel powered commercial aircraft. Smaller conventional engines could provide enough power for level flight while electric engines provided extra power for takeoff and climb to altitude.

[@RealistReviewer]

Yes this needs to happen, air travel costs far too much (due to fuel costs & carbon tax) and if we can substantially lower costs and emissions with hybrid airliners it's a win win. I dream of a world where we can travel anywhere at the cost everyone can afford, the poorer members of society need travel the most because the more you travel, the bigger your scope becomes.

[@FPVREVIEWS]

check out the boeing sugar volt project, it's almost exactly what you are describing.

[@Miata822]

FPVREVIEWS Cool! Thanks.

[@herbertshallcross9775]

@@RealistReviewerPower density of electric or hybrid IC/electric systems are quite low compared to Turbofan systems. A hybrid Turbofan/electric system has little promise of increasing efficiency or lowering airfares.

[@herbertshallcross9775]

I don't think you have conducted a proper survey. There have been about a half-dozen human carrying solar powered aircraft. There are perhaps a hundred electric powered man carrying aircraft, and they don't use solar cells for anything except powering the instruments. The overwhelming number of non-human carrying aircraft have been radio controlled hobby planes or multi-copters, which rarely if ever use solar cells. @cprich22

[@pauleverest]

absolutely brilliant stuff. can't wait to buy one

[@kamikazekunze]

Great stuff! Simply amazing.

[@jerrymiller8313]

saw something that said the fuel weight of an airliner that could fly from NY to Europe with reserve, if translated to battery power wpuld power the same airliner for about 20 min.

[@computer5272]

Contrary to popular belief noise isn't an area where electric planes will make any difference. All of the noise you hear from most common airplanes is the propeller, the engines actually don't rev that high and aren't particularly powerful or loud.

[@DrewLSsix]

Computer. er, no. try listening to an engine on a test stand with no prop.

[@computer5272]

Try listening to a prop with no engine, it sounds the same.

[@EdgyNumber1]

Computer you could easily knock of 10dB (note: log scale) without the motor, however, this would be with a conventional propeller on an electric motor. because of the movement of air around both props, compared to conventional piston-prop engine, there may not be much difference in volume, although sound pitch might be higher without the sound of a piston engine.

[@areolaman]

Most piston aircraft engines have no muffler and at high power settings are louder than a leaf blower

[@Power_DC_Official]

Contrary to Computer's statement electric aircraft IS quieter. I'm working daily near electric aircraft (check Pipistrel Alpha Electro) and also piston engine aircraft and the difference is huge (Rotax 912 vs electric motor). In the air and on the ground.

[@Robo_Jo]

What a great episode Robert, really informative. Wish Electroflight all the best with the project

[@gooniac33]

I have been an avid RC aviation nut for over 30 years now...The last 10+ years have been exclusively electric and for all of the reasons listed in this video. When I started back in the the days the planes were all nitro powered, heavy, noisy and messy. It was the only way that we could fly. But then the first brushless motors hit the market and everything changed. The thrust to weight ratios went through the roof and the ease of operation was even better than before. I now have models that are capable of 180mph while only consuming about 380watts of power. That was unheard of in the past. Electric power has come so far with batteries being the only thing holding us back. Thankfully they are catching up now! Fully electric cars are a reality now with the planes not too far behind! Take a look at my channel to see what the RC variants are capable of now...
