At the air show in Dubai presented the first electric "racing" aircraft

Various performances continue at the Dubai Airshow aviation new products. One of those that attracted special attention - the first electric "racing" aircraft.

We are talking about an electric aircraft, designed primarily for high-speed aerobatics at low altitudes as part of special competitions in the class of light-engine aviation. Often these competitions are called Aviation Formula 1.

The electric aircraft E-Racer, presented to the public at the aviation salon in the UAE, was created by specialists from the British company Team Condor. The creators of the electric airplane say that the Cassutt aviation class was chosen as the basis (these are single-seat light-engine aircraft developed in the United States at the beginning of the 50's).

The electric aircraft E-Racer uses a twin power plant Contra Electric, which propels the propeller with the so-called opposite rotation.

An electric motor allows the aircraft to reach speeds of up to 483 km / h (300 mph). The maximum power installed for racing on the E-Racer will be 150 kW. An 100-kilogram lithium battery is installed under the fuselage of the aircraft, which will ensure the 10-minute high-speed flight with reduced engine power.

The model of the electric aircraft received the working name "White Lightning". The total cost of the British project to create such an aircraft was about 13 million pounds (this is approximately 1,07 billion rubles). The project manager is Richard Glassock, a researcher at the University of Nottingham.

It is reported that for the first time "White Lightning" will take part in air races tomorrow - November 19.

The main thing is that the batteries are enough for the flight. And so the idea is not bad.

[Civil]

Again a propeller, or maybe there is an electric analogue of a jet engine?

[Mastrer]

Yes, but in terrestrial conditions current models are poorly applicable.

For a billion rubles? Such a dull hat?

One hell, in order to get electricity and charge this hat, you need to burn hydrocarbon, ruin the landscape with a dam or use a nuclear reactor. The battery is also the battery, which is the transmission link from the burned fuel to the device. And with losses. And tolerances, all kinds of garcons, etc. And do we need these intermediaries? Feel free to burn hydrocarbon in your internal combustion engine, spin the propeller with it and fly to health, and most importantly ... no billion

10 minute speed flight

There are no rechargeable sockets in the air!

[rhino]

They will make not a tanker, but a flying power bank. Who cares ???

[Uncle lee]

Put a plus who has a socket!

[Catfish]

There are ten outlets around the house, but I was able to put a plus on only one

[Uncle lee]

Kostya Everyone has sockets at home. I asked who has in the sky .....

[Catfish]

Volodya , I can’t say anything about heaven, not my diocese ... for now ... And about the plus, I respect people with a sense of humor.

[Uncle lee]

In the words of John Silver - Pirates love a good joke and know how to have fun ....

[Catfish]

Silver himself was a clever man and possessed this very feeling, very good. well managed to convey this to Oleg Borisov.

[Uncle lee]

I like Boris Andreev more!

[Omskgasmyas]

Plus, as expected, grounded, minus threw up, catch it!

[Denimax]

Why an outlet? It is necessary to fly into a thundercloud, maybe it will recharge.))

[abrakadabre]

Make a descent current collector, like a tram, and fly along electric lines.

Electric plane E-FAN. Designed by Airbus. Its electric fans imitate, give a similar stream, as on a turbofan.

Only this:

[Skay]

But maybe there is an electrical analogue of a jet engine?

There is. The impeller is called. But he is more a jet engine simulator than an analogue. And he has lower efficiency.

[Alexander Petrov1]

Until super light and at the same time super powerful batteries are invented, electric planes will not develop.

[igordok]

Place a wind generator and power the electric motor from it.
Almost a "perpetual motion machine".

[bessmertniy]

The attempt is not torture. For a variety of flying races, the model is quite decent.

Everything happens once. Previously, a flashlight on a fresh battery shone for half an hour and that's it. Now there are compact batteries on which the flashlight can work continuously for XNUMX hours.

Only a revolution occurred in emitters, not power supplies. It was possible to sharply reduce consumption, and the battery capacity has not changed much.

[Fikys]

You are not entirely correct. The capacity of batteries (cells) has also changed significantly. Compare the capacity of the element "373" of the Soviet era and the capacity of the cell, for example, "Durasel" D. Batteries - too. Compare the weight and dimensions of lead acid and lithium polymer of the same capacity. The difference is also at times.

Panasonic launched its first lithium-ion battery more than 20 years ago. Since then, nothing has changed dramatically in its capacity.

You know, actually, "Li-ion" batteries were invented back in the late 70s by an American scientist (I forgot my last name), but the first serial industrial Li-ion battery introduced not Panasonic, but Toshiba - back in 1991 !!! True, they became widespread only in the late 90s - early 2000s!
Compared to the "good old" nickel-cadmium, they had a MUCH higher power density: before 240 Wh / kg against 45 – 65 Feet Wh / kg !!!
More "capacious" batteries have been developed: silver-zinc (up to 425 Wh / kg and lithium sulfur (approx. 480 Wh / kg), but due to the "congenital defects" that have not yet been overcome, they still have an extremely LIMITED area of ​​application!
Therefore, your "comment on comment" YOUR (Vladimir) , no matter how it makes sense - it is RIGHT! Not only progress in radiation sources, but also in power supplies (!) led to the fact that Chinese [/ i] a flashlight that was in my childhood (by the way - very qualitative!) - it worked 1 - 1.5 hours, and the Chinese flashlight (by the way - not the best quality!) which lies in my pocket today - works [i] for almost a day!!!

[Cheerock]

Therefore, your "comment on the comment" YOUR (Vladimir), as if DOESN'T make sense

The meaning is very simple. The most common lithium battery is Panasonic. For 20 years, its capacity has not changed dramatically. There is no breakthrough in energy storage devices yet. In my sports car, I use Li-Fe-Po, for example. Yes, the recoil current is impressive, but the dimensions are impressive, and the price is impressive: a 40 amp clock costs almost 100 sput. At the same time, do not run in frost, do not overheat, do not discharge to zero, and there are still many different "no".
Expensive, uncomfortable, unsafe. And there is no progress.

Do not tell! The battery capacity has increased significantly, but there’s no way to save energy - you can’t just take and reduce the power consumption without changing the power of the engine itself. It is another matter if an energy source appears that has different principles of accumulation.

[Elephant]

Meanwhile, in Spain, the local Graphenano and the Chinese are building a plant for the production of graphene batteries.

[dvina71]

Quote: ROSS 42

Battery capacity increased

Alkaline, acidic and other other chemicals - no. It’s just that every chemical reaction has a dependency on the components. Say alkaline batteries can stably and for a long time give a strong current, the acid one has a token of the starting current, which is several times larger than the current discharge .. look at the label carefully .. you have the capacity and current .. there are still no lithium batteries for cars and there are reasons for this ... but there are such batteries for the electric car .. So no revolution in chemical reactions has happened ... and for a long time the acid ones will be the main ones for cars ... and turbines for planes ..

My father had a flashlight with a flat battery, even now I remember the name KBSL, and then he bought a Polish battery. The neighbors had a Soviet one, they worked on large, like 5 rubles, batteries.

Wow And my bati still had an army (WWII) aircraft flashlight - so it generally worked WITHOUT any BATTERIES !!!
Think - "bullshit"? No matter how it is! IN FACT!!! There was a "pedal" (dropped the clamp - and work with your hand! shines!). It just had a built-in miniature "dynamo"! Cool contraption (only the palm got tired quickly)!.

[Astra wild]

Fi "America was discovered". I know this flashlight well: my mother-in-law called it "a bug" - small and black. I had one 5 years ago, but where is it now? Haven't seen it for a long time. 2 years ago I saw modern electro-dynamic lights on the market, but they left me indifferent: nothing to do with my childhood

Battery for an hour of flight, it turns out at least half a ton? For such a small aircraft, the weight is excessive.
What should I do. Despite all the extremely rapid improvement of the batteries, the specific capacity must be at least doubled ...

Under the fuselage of the aircraft, an 100-kilogram lithium battery is installed, which will provide an 10-minute high-speed flight with reduced engine power.

At xnumx minutes, however. Take off and sit down. Well, fly a bit like plywood over Paris.

If only not one way flight.

Eugene! Batteries have already appeared which in terms of power density exceed lithium-ion (and lithium-polymer - too) - at least DOUBLE! Alas! Due to purely operational issues (and fantastic value) - They did not get wide distribution!
Maybe these are exactly the ones on this airplane (silver-zinc or lithium-sulfur) ??
What they write "lithium-ion" may turn out to be "disinformation"!

10 minutes is enough, tea is not a liner. For longer flights, fuel cells are better suited.

[gridasov]

I bought an electric scooter for the children. A month went by and bam died. For no reason, just turned off. So I’m thinking about a dozen connecting points, where, simply due to the contour processes, it jumps to ON and OFF micro-breakdown and the conductivity changes. Each individual device affects the operation of the controller and the control unit. But the scooter took and got down from it, and the airplane then flies and falls. Therefore, all this bragging is not from the mind and the decisions should be different. Guaranteeing complete safety from outages and unintentional falls

And there is no outlet for recharging! I wrote about this above, but people were offended ...

As my brother taught me, the people are a herd of what they teach and feed and live on. Therefore, how are they offended at me for what they are told about the case. Never mind.

Nothing should confuse - this is a reality that we do not always like. I’ve been talking about new types of mover for years, and it’s not strange that sometimes they ask what kind of beast. But they don’t make contact and ask for open description. This is normal?

[Uncle lee]

I don’t know ... People have different interests and needs.

[Chaldon48]

Flight to nowhere. Interestingly our billionaires are interested?

[Astra wild]

I present a picture of such a plane flying, and the pilot shouts: where is the socket !!!
He drives very electric scooters past my house, and one of them felt that he shouldn’t drag him to the apartment, he carries an extension cord with him. Now electric planes have appeared, which is next in line: electric power?
