NASA is experiencing an unusual electric wing with 18 engines.

NASA has begun testing its new product, the Leading Edge Asynchronous Propeller Technology (LEAPTech) electric wing. This unit is significantly different from traditional aircraft wings, as it is equipped with 18-th miniature electric motors, according to the portal Gearmix with reference to Slashgear.

“The wing uses a battery based on lithium-iron phosphate to power its engines, and each engine can be controlled independently, which allows the flight engineers to optimize their speed for maximum performance,” writes the publication.

According to the resource, the wing does not imply the development of high speeds, "but it will be three times faster than the solar" Solar Impulse 2 ", which bends around the Earth at a speed of 40 kilometers per hour."

The device is developed by two private companies ESAero and Joby Aviation. NASA hopes electric motors will become “an essential part aviation industry ”, because, according to experts, they are safe, environmentally friendly and effective.

It would be nice if we, too, in the development of innovation would be on top, but there Chubais, wait for the failure.

The more complex the technique, the higher the possibility of failure. Note the fuselage / wing ratio.
The direction is interesting, but electric motors will be inferior to conventional ones for a long time.

For fifteen years now, electric motors have surpassed ICEs in terms of efficiency and price. The only problem is the power source.

[Kolka82]

So I'm not an aviator engineer, but the proportions of the wing and fuselage somehow confused me. One should be guided by Mother Nature - the winglets (tips on the wing of an airplane) were copied while watching the flights of "soaring birds".

Yes, not electric motors. They just have crazy efficiency, but energy. In short, we need efficient generating devices.

But why? A 3KW engine has long been easy to fit in a fist.
A gasoline piston?

To the power density of reactive - yes, so far. But reactive and not consumer goods, and if high-temperature superconductors are used, it is also possible to obtain orders of magnitude greater power in general. So there is much to develop.

Well, the batteries also do not stand still.

This is all pampering. In the USSR, they successfully tested an atomic aircraft and reached the final tests - flight, where the aircraft showed its best side. But over the decades since then, technology has made tremendous progress. And I don’t think science fiction is a modern-day aircraft. Flying boat. Single engine, with coaxial thrust screw in the ring. With a reverse sweep wing according to the duck pattern. The presence of front horizontal plumage and the complete absence of the tail, the role of which is played by the wing.

Sure! How much gas, fuel oil, coal, uranium do you need to burn, finally, to get electricity? And yet all this needs to be extracted from the ground with attendant consequences. How many dams should be built by flooding the land? Windmills occupy huge areas, and also create "environmentally friendly" low-frequency waves, including infrasound. All sorts of birds and other animals are afraid of this. Solar panels? Wai jalab! They are made in the same production, polluting the environment, by the way, using the same electricity. In the shops - sterile, around the plant - not always, to put it mildly. The electricity obtained from the Sun must be stored somewhere, for example, accumulated in batteries, sorry. What are these made of? That's right, from all sorts of nasty things, but looking for they have a service life, after which disposal follows, they say, having a positive effect on the world around us (electrolyte in the toilet, so as not to clog up, plastic in a landfill, and from lead, cool pigs and brass knuckles are obtained, sinful, I repent. As an option - remelting is environmentally friendly etc.) . Well, in general, a mona novel to write. That is, damage is inevitable, it just needs to be minimized. And so: I - FOR ELECTRICITY! And no nails (V. Mayakovsky), here is my slogan and the sun!

I remember in a distant happy childhood, when the grass was greener, and the rainbow and the color of the sky did not cause bad associations, we sang one song (I’m not giving it completely):

Ah, electricity, you are light, you are our strength!
Ah, electricity, you opened the door to the world!
Opened by the atom you damned on Earth,
On Mars, vodka and a snack on the moon. . .

. . . You go home you're drunk, a little alive
The wife meets with an electric poker. . .

and in the end :
. . . The prosecutors will judge us,
We will be caught by electric garbage,
And how to catch, there’s no return,
And then electricity will not help.

"Solar Impulse 2" that bends around the Earth at 40 kilometers per hour. "

Does the plane fly at a speed of 40 km / h? Even a bird is faster.

Gray cranes, silver gulls, large sea gulls fly at a speed of 50 km / h, finches, siskins - 55 km / h, killer whales - 55-60 km / h, wild geese of various species - 70-90 km / h, sviyazi - 75-85 km / h, waders of various species - an average of about 90 km / h. The highest flight speed is observed for the black swift - 110-150 km / h [42]. The hollows showed amazing endurance: they are able to fly at a speed of about 100 km / h over more than 6500 km [47].

The highest speed of the diving flight is observed for the Peregrine Falcon - up to 320 km / h.

As for the environment - to make this electric waffle, how much copper should be extracted? how many polymers? other metals? how much fuel do you need to burn all this? Talking about ecology on the background of the electric motor is PR and brain pollution.

Nothing new and as a result, the increase in efficiency is minimal. Unresolved issues of fundamental physics. Algorithms for organizing hydro-gas-dynamic flow at the old level. At the same time, new methods for the analysis of complex hydro-gas-dynamic processes, including turbulent ones, were created, and devices based on new principles for organizing these algorithms were created.

Sorry, but just like that, the conversation is about the fact that simple transformations, like well-known design solutions, but the real physical effect is fundamentally different. Radically different! This means that a fundamentally new technology and new possibilities are behind the simplicity and simplicity of implementation. This is precisely the physics and understanding of the aggregate essence of transformations both in the most mobile flow, but also in the principles of the construction of the basic device. Let me just say. There is a unique opportunity in one process to combine both kinetic processes and use the potential energy of the medium. For example, the same Rossi uses a "static" form of organizing the interaction of known substances in interaction with a known gas. And with such a device, it becomes possible to organize the dynamics, due to which the release of hydrogen occurs and the structural parts of the device made of metal are the outflow surface. So, everything is much simpler, but much more effective.

Sorry, but this is exactly the conversation that simple transformations, like well-known design decisions, but the real physical effect are fundamentally different.

The propeller (air) oncoming air flow "chops", creating a kind of vortex flow behind itself, which is then again interrupted by the wing plane.

Energy is lost only on these "metamorphoses".
And "simple transformations, like well-known design solutions" (like that story in the article) do not change the essence of the problem.

But due to intensive blowing of the entire wing, the lifting force increases. An attempt to use the Coanda effect was used in the development of AN-72.

It would be even larger if the motion vector of the air flow blowing around the wing were parallel to the plane of the wing.

This is not just an article — THIS IS A REALLY ACTING FLYING PLATFORM!

A strange man really flies over the Ruzsky reservoir. From the city of Ruza to the village of Glazovo, he rides along the way. The base does not go directly to the reservoir. In the backpack there is a camera from the truck and a pump, a motorcycle battery. Inflates the camera with air, attaches some kind of coil, grid, battery. He does everything over the hole. At first they thought it was his poaching tack. Yes, that's just seen him. Rises by five meters and flies towards the dam.

"March 2, 2007
I lost four days off, wandering around in search of a miracle of the unit, burned a ton on a wheelbarrow of fuel. What can you tell about this man. Name is Alexander. Age 55 years. Lives in the city of Ruza. Electrical Engineer. On weekends, in the morning you can meet at bus stop number 25. (Ruza - Ostashevo) Glazovsky bend and travel 3,5 km to the bases of Glazovo, asking about his homemade products. A person lives poorly, plainly everything is exactly what you don’t know. He knows nothing about Grebennikov and AVION. Carries a backpack with him. In the backpack there are stainless steel mesh coils, a gluttonous generator, a control panel and a battery, a small car pump, a camera from the ZIL 130 wheel. Two boards are attached to the backpack, more precisely two stripes of laminate flooring. Comes on ice, pumps the camera with air, puts coils and nets on the marks. He puts two boards on the camera, sits on top, turns on the generator and rises slowly by 3-4 meters. Then it switches on another mode and flies at the same height towards the Luzhka Recreation Center over the frozen channel of the Ruzsky reservoir, making a 12 km path in the air, and there is not enough battery charge for more. Not a motor and no blades. Flies only in winter, starts only with ice. You can meet him on the P108 highway near the rest house on the same side or at the stop of Belyanaya Gora railway station and bring 11-12 km to Ruza. In short, I did not like boring all this and sad, I need to pick mushrooms in the summer, and in winter I do not need it for nothing. The main thing I did not understand what for him to fly in the winter unnecessarily. "

I completely agree. But the idea is interesting anyway. By the way, on the aforementioned AN-72, this effect gave up to a 20% increase in lift. Until it came to a series - it was necessary to increase the carrying capacity, they made a wing of a larger scope and the idea left no more than 5-7%. And on the further development of this line - AN-74-300 - the engines are already on pylons under the wing - this allowed to increase the speed, range and economic efficiency of the aircraft due to improved aerodynamics.

Look at the gliders - it is a thin, narrow wing with a large span that allows you to achieve the maximum aerodynamic quality (for example, 50 - that is, when gliding, the plane descends by 1 meter, flying 50 meters horizontally). In combination with the Coanda effect (intensive airflow of the wing), we have a significant increase in lift. Of course, this design is optimized for efficiency, no one expects speed records from it. And electric motors have long surpassed "ordinary" ones - it is difficult to come up with something more reliable and simpler than a brushless electric motor.
