In Novosibirsk, created a fully aluminum aircraft engine

75
The world's first all-aluminum aircraft engine was able to create the designers of the Novosibirsk State Technical University. Even those parts that are subjected to the highest loads are made of aluminum: the crankshaft, sleeves and flywheel.


The use of aluminum instead of steel made it possible to reduce the weight of the engine by 40 – 50% compared to traditional engines of similar power. When equipped, it will weigh at least 200 kg, while the weight of the predecessor, the M-14P engine, will be at least 250 kg.

In Novosibirsk, created a fully aluminum aircraft engine


At the same time, the power of the new engine increased by 40 horsepower - to 400 horsepower, and fuel consumption decreased by about 15%.

Aluminum has already been used in aviation and automotive engines, but high-load parts are still made of steel. Scientists managed to replace them with aluminum ones using a special technology of plasma electrolytic oxidation (PEO), created at the Institute of Inorganic Chemistry of the SB RAS.

The new engine is planned to be installed on the YAK-52 aircraft, which are used as training aircraft in DOSAAF schools, as well as private and commercial aircraft.

Ground tests of the engine were successfully performed at the Mochishche airfield near Novosibirsk 19 on January 2018. Now the creators will test the declared engine life, which is not less than that of steel motors - 2 000 hours. After that, the engine will be installed on the Yak-52, and its flight tests will begin.

The engine will use regular AI-95 gasoline. Also, it will be installed autonomous heating system. It is assumed that in serial production the engine will be half the price of modern analogues.

      In Russia, this “story” is still worth several hundred aircraft at flying clubs. Many with exhausted engines, and there are no new engines and there is nothing to replace. The plane itself is very good. I flew such a flying club at the end of the 80's. At our old airdrome, the air club is located now, there are airplanes, and the resource has been exhausted. It’s easier to buy a new engine than a full airplane. hi

For the 17th year, 12 cars have been installed on the wing. Today, the mustache! Denyushki-yok! The rest 22 cars, probably in disassembly.

        That's right. Mostly patented are designs and methods. But technology is much less common. In the patent, everything should be set forth in detail, it is clear to the specialist. And to track in this case a patent infringement is much more difficult than in the case of design theft.
        In the world there are few who want to put their know-how on sale. Better to trade in finished products.

        Never make aluminum sleeves laughing , and even more so do not cover with titanium nitride. The cylinder is completely cast, together with cooling fins, the place where the sleeve should be is either covered with a layer of chromium, or ion-plasma remelting is done in an atmosphere of special gases, obtaining a very hard surface.
        The only motor is a BMW, where sleeves of high-strength aluminum ALLOY are cast together with a magnesium alloy cylinder.
        The connecting rods are made of titanium, crankshafts - once, titanium has a vile characteristic of permanent deformation and extremely poor friction coefficients, it is necessary to constantly wrap it with antifriction materials.

          I didn’t put it right. The walls of the monoblock are covered with a nikosiloy spraying. I’m not quite a chemist and technologist, I won’t tell you the formula. There’s the same technology, in my own words I’ll say that you don’t touch only ceramic spraying with a coating thickness of other 50 microns. And the crankshaft is again a little wrong put it, from titanium alloys, well, something like BT18 (y) .In principle, you can pick up the necessary characteristics. The only thing is that its resource will definitely be less than a knee made of cast iron or steel. Well, in addition to BMW, there is also an Audi, a Porsche, a jaguar. Suzuki makes some motorcycles. 15 strong boat Mercury. and the first block with aluminum sleeves was put by Americans in 1971 on the Chevrolet Vega. but this is not the most successful engine.

    An aluminum engine is, of course, good, but the idea of ​​the internal combustion engine itself is somewhat ill-conceived. It is necessary to replace the thermodynamic cycle and the motion converter, then it is possible to significantly increase the specific power, and this is pampering.

      Of course, the developers do not know anything about it.
      Expectedly spread all-trolls.

        They know, maybe they know, at least they think well, but to solve this problem, a different construction is needed, and mathematics alone is not enough for this. Already there are even single-cycle engines, so let them dig into patent databases.

      It is better to refute Thomson's postulate, then thermodynamic cycles will not be needed.

    While the breakthrough is not particularly clear. An aluminum engine stands on Solyanka and gives 200 thousand kilometers and scrap. There are no shells, the walls are thin, they can’t be bored. Can’t this be a similar situation?

    In 1979, American Matti Holzberg founded the company Polimotor, whose main task was to create an engine with as many plastic parts as possible.
    The first polymer engine was a copy of the Ford Pinto 2,3-liter four-cylinder engine. It is he who is depicted on the cover of the journal "Popular Science" for 1982.
    The cylinder block, pistons, connecting rods, crankcase and most of the cylinder head were made of plastic. For the manufacture of the piston head and liners of the combustion chamber (liner), aluminum and steel were used. The crankshaft and valves are also made of metal. The engine power of plastic was brought to 300 liters. with., and the mass is reduced to 69 kg (the original engine gave 88 liters. from. with a mass of 188 kg).
    In the 1980s, cars with plastic motors took part in car racing, where they showed their reliability, but they could not interest large automakers, the cost of producing special composites that could withstand significant mechanical and thermal loads was too high at that time.
    Now similar work is being done by the NAS Fraunhofer group NAS.

        We tried with a tree! Garage52 on YouTube take a look. There, the engine was washed with dishwashing liquid, and the wheels were pumped with mounting foam ...

    Yeah. The predecessor weighed 250 kg, and aluminum - 200, which is 40-50% lighter. belay

    Those were iron pounds, and these are aluminum!

    reduced engine weight by 40–50% compared to traditional engines of similar power. When equipped, it will weigh at least 200 kg, while the weight of its predecessor, the M-14P engine, will be at least 250 kg. [Quote] [/ quote] Something bad with math ...

    Experimental sample, I think! Aluminum alloy crankshaft won't work! Alternating loads are too large. Cranks too. The liners have long been made from silumin with a nickel coating.

    I have seen so many times the news of domestic piston engines for ALS at exhibitions, that I have no doubt that there will be no competition in our market for Laicamings and Rotexes for a long time. And enthusiasts like flying on auto conversions of all sorts of Subaru will fly.

    NSTU is not an academic campus like BE))) this is the former NETI at the student

    Scientists managed to replace them with aluminum using a special technology of plasma electrolytic oxidation (PEO), created in Institute of Inorganic Chemistry SB RAS.
    The Institute of Inorganics is located on the Lavrentyev Avenue on the academic campus
