Charomsky and his diesels


As mentioned in the previous part stories about the unique 5TDF diesel engine, the roots of the power plant go back to aviation motor building. And first of all they are associated with Alexei Dmitrievich Charomsky.

Charomsky began to deal with the diesel theme back in 1931, when at the Central Institute of Aviation Motors named after V.I. PI Baranov (TsIAM) created a group of diesel engine builders or, as they were officially called, "the department of oil engines." By the way, Vladimir Yakovlevich Klimov became the head of the second "department of gasoline engines", after whom the world famous engine building company will be named.



A sign of the 30s was the rush pace of development of everything and everyone - the country's leadership demanded the solution of the most difficult technical problems and putting it into production within a couple of years. Charomsky's group was supposed to develop a whole line of diesel engines of various classes, but in the end, only one came out. It was a 12-cylinder "oil" AN-1 with a capacity of 913 liters. with., which was supposed to be mounted on bombers. By the way, Charomsky's engine turned out to be quite modern.

When compared with the captured Jumo 205 from the Junkers Ju 86 bomber, the AN-1 showed itself on the good side - it was more powerful, more reliable and worked more stable. The history of the AN-1 was long and inglorious.

But the German diesel deserves a separate mention. It was a 6-cylinder, 12-piston, vertical-cylinder diesel engine. The 600-horsepower unit came to the Soviet Union during the war in Spain and aroused genuine interest among engineers. After a two-year study, it was decided not to adopt the exotic scheme and continue to work on V-shaped motors. The official version is that the German diesel is too unreliable, although it has high specific characteristics. In fact, the captured motor was too complicated for production at the factories of the USSR at that time, and full compliance with the technological cycle was impossible.

The attentive reader will surely see in the scheme of the two-stroke turbo-piston Jumo 205 a prototype of the future post-war tank diesel 5TD and will be absolutely right. German ideas will find their embodiment at a completely different level in the USSR in the early 60s. It was then that the high specific characteristics of the diesel engine came to the fore. Only not with the aviators, but with the tankers.


Jumo 205 is the ideological inspirer of Alexei Dmitrievich Charomsky. Source: ru.wikipedia.org

But let's return to 1938, in which Charomsky was sent to the NKVD sharashka at plant number 10 for 82 years for a delay in the development of aircraft diesel in the same year. Here he developed two diesel engines - a 24-cylinder M-20 and a 12-cylinder M-30. The latter went into series and even managed to take part in the bombing of Berlin on August 11, 1941. One of the TB-7s was equipped with 1500-horsepower Charomsky engines.

The experience of Charomsky's group, accumulated during the development of the AN-1, came in handy in the development of the world's first tank diesel engine V-2. The leading employees of the "department of oil engines" of CIAM were sent to Kharkov to department 400 of the plant No. 182 to help local engineers.

Some commentators talk about the aviation past of the B-2 tank with some disdain, they say, they could not tank engineers cope on their own. There are several aspects here.

Firstly, in Kharkov, the experience of diesel engineering consisted exclusively in the construction of low-speed marine engines.

Secondly, only the aviators at that time had at least some skills in creating high-speed diesel engines. And high-speed diesel engines for land vehicles have completely different requirements for design, materials, and mass-dimensional parameters. Therefore, it is quite logical that the AN-2 aircraft diesel engine solutions were taken as the basis for the B-1 design. Simply because nothing else was at hand, and the war was already so close.

But let's return to the fate of Alexei Dmitrievich, who was released from prison in 1942, and until the beginning of the 50s he was exclusively engaged in aircraft diesel engines. But the era of piston technology in aircraft construction was leaving, and Charomsky was not predisposed to the development of jet engines.

More powerful and more powerful


Kharkov 5TDF was born from the U-305 single-cylinder compartment. This compartment was a kind of module of a large 10000-horsepower M-305 diesel engine, which Charomsky tried to attach to aviation in the early 50s.

Alexey Dmitrievich took as a basis the German Jumo 205 engine, half-forgotten by that time. It was not possible to create a serial engine, but Charomsky defended his doctoral dissertation on this project.

Whom should they contact with an exotic idea that was unnecessary for aviators?

For shipbuilding, the engine was too fast and low-resource. Remained - tankers, who were just thinking about the technology of the new generation.

The chief designer of the Kharkov plant, Alexander Alexandrovich Morozov, took the idea very well and immediately appointed Charomsky as the chief for tank engines in Kharkov. And here again peculiar circumstances intervene.

In Kharkov, in the early 50s, practically no one was left in the engine design bureau from the pre-war composition. Most of the evacuated engineers settled in the Urals and gradually brought to mind the proven design of the B-2 there. Only a few have returned home to plant No. 75 from the Chelyabinsk Tractor Plant. To take the palm from the legendary "Tankograd" and Nizhny Tagil, the Kharkovites needed a revolution. And in the motor-building business, Charomsky became the main revolutionary, in the shortest possible time he gathered a strong design bureau around him.

The first prototype was a four-cylinder 4TPD assembled from four U-305 modules. The diesel turned out to be rather weak - only 400 liters. with., and it was decided to add another cylinder. This is how the 5TD "suitcase" appeared already with 580 liters. from.

In January 1957, the motor passed state tests. But the promising T-64 was definitely not enough, and the chief designer Morozov put forward demands to increase the power by another 120 hp. from. Charomsky, if you follow the official version, just at that moment leaves the post of chief designer of motors at Kharkov plant No. 75 for health reasons.

However, his health condition allowed Aleksey Dmitrievich to work for 15 years later as head of a department and deputy chief designer of the Institute of Engines of the USSR Academy of Sciences. Therefore, it is quite logical to assume that the real reason was either the conflict with Morozov, or the inability to bring the 5TD design to the required recoil parameters.

However, there is a third assumption - Charomsky understood from the very beginning that in a five-cylinder version it is extremely risky to squeeze 700 hp out of such an engine. from. Serious forcing, which was resorted to in the future in the 5TDF version, negatively affected the resource and reliability of the tank diesel engine.

After the departure of Charomsky, Leonid Leonidovich Golinets was appointed the new chief designer of the diesel engine.

By March 1963, the 5TDF variant of the required power of 700 liters. from. successfully coped with 200-hour tests at the factory, and a year later with 300-hour tests. But these were only tests at the factory. The military acceptance, always famous for its rigor in the Soviet Union, brought 5TDF out of the “comfort zone”. As a result, in 1964, joint tests with the military, the two presented motors failed, having withstood 22 and 82,5 hours of continuous operation. There were years of improvements ahead, some of which were already in military operation after being put into service.

Oil instead of diesel


The history of the "oil engines" that Charomsky had been developing since the 30s would have been incomplete without experiments in replacing diesel fuel for tanks with oil. According to Russian engineers, the potential ability to "digest" oil would be very useful in a war. The rear units did not have time to bring diesel fuel - and the advancing tankers refueled their vehicles from the nearest oil pipeline. Fortunately, the Soviet Union had already built the Druzhba pipeline to Europe by the 80s.

The experimenters did not dare to pour oil into the T-64 with its capricious 5TDF, but took the proven T-55. Apparently, they realized that the engine after the experiments would go for decommissioning, and it would be better to get off with a little blood.

On oil, the specific thrust of the V-2 diesel engine decreased by 20-30%, the average speed fell by 12%, the track fuel consumption increased by almost a third, and the cruising range fell by 22%. The oil naturally rapidly coked and tarred the injectors, did not burn completely in the cylinders and flew out into the exhaust tract, where it burned out. In such cases, the T-55 glowed with one and a half meter tongues of flame from the exhaust pipes.

Amazingly, the cylinder-piston group did not suffer much and was only slightly covered with carbon deposits. The engine oil felt much worse - after 20 hours of operation, it thickened so much that it threatened to stop its supply to the rubbing surfaces of the diesel engine. As a result, the coarse oil filter was clogged with all the ensuing consequences.

But in the conclusions of the experiment, the authors still gave recommendations on the possibility of refueling the tank in extreme conditions with oil from the nearest pipeline. At the same time, the tank was enough for only 1,5-2 hours of hard work.

Only now, the structurally refined 5TDF had nothing to do with these curious (or barbaric) tests.

    and Charomsky was not inclined to develop jet engines.

    Still as it was not - in the 30s he gave a negative conclusion on the prospects of the gas turbine installations of Uvarov V.V. On the other hand, he perceived turbocharging very favorably and actively applied it (though already in the 5s, and there was no place to go).
    But the diesel, of course, is his life.

    It is very interesting, in the future, to receive from a respected Author a comparative analysis of the "suitcase" with the closest analogue of the Leyland engine on British tanks. And yet, how did the T-80UD show themselves, that Ukraine delivered to Pakistan? After all, several hundred were delivered with "suitcases". Thank you.

    Maybe a little off topic. During the war, my father served as a mechanic (minder) at the airfield. He said that new engines were installed on fighters (apparently, Yak). After the resource was exhausted, they were sent for repairs and then installed on bombers (Pe-2?). And after the resource was exhausted, the bombers were sent to the factory, the cylinder heads were changed, a number of alterations were made - and a diesel engine for T-34 tanks was obtained. Is it so?

            On the T-34 in late 1941 - early 1942. war, when there was a shortage of V-2 engines, they installed the M-17 aviation gasoline engine (tank version of the M-17T)

            According to various estimates, tanks with these engines were produced (STZ and Krasnoe Sormovo) - 1300-1500 units.
            There is also such information (with some differences from the previous one):
            "The lack of diesel engines was compensated by the installation of M-34F carburetor engines in T-17 tanks, which underwent three to four major overhauls. 12-cylinder, 4-stroke, V-shaped, M-17F carburetor engines were previously installed on light BT tanks. -7 and even more consisted of supplying the Red Army. As a backup option for a possible replacement of the V-2 diesel engine, the issue of installing the M-17F engine in the T-34 tank began to be worked out back in June 1940 in the "500" workshop of the plant number 183. Work on this topic was forced after receiving the order of the Council of People's Commissars of the USSR dated September 16, 1941 "On the installation of the M-17 engine in the T-34 tank." The modification of the installation of the M-17 engine in the T-34 tank was completed in an extremely short time. No. 5 and the designers, the documentation was transferred to STZ and Plant No. 183. The final decision on the installation of the M-112 carburetor engine in the tank was made at the GKO meeting held on October 17, 4.
            The largest number of T-34 tanks equipped with M-17 engines was produced by the Gorky plant number 112. In 1941, 156 T-34 tanks with carburetor engines were manufactured on it. Until May 1942, 112 more combat vehicles with such an engine were accepted by military representatives at factory number 540. At STZ in 1941 17 T-197 tanks were equipped with M-34T engines (October 15, November 85, December 97). Another 12 combat vehicles manufactured in December 1941 had M-17F engines.
            In January 1942, STZ produced 134 tanks with aircraft engines, in February - 135, in March - 95. "

They take as a basis from the carburetor block, KShM, timing, lubrication, cooling, start-up systems, make a new head, a new power system - this was, for example, "Peugeot-Identor" - this is the engine's name.

              Take. Only now the output turns out ... The specific load of the diesel engine is too high for a delicate carburetor base - it quickly becomes unusable. Actually, they "did" not only in the West. In Bulgaria, then we converted the 2103 engine, in the end - "they counted, wept".
              "Behind the wheel": "... As a result, many diesel VAZs" ran "to serious problems with the" heart "of some 30-40 thousand, after which damage appeared on the pistons and cylinders, incompatible with the further operation of the unit without major repairs, which boiled down to replacing the block along with the piston ... "- in fact, there were much more problems. So, the engine stopped working because its bolts were stretched, compressing the gas joint. Knowledgeable people, in order not to change the gasket under the head, began to change them every 15 thousand - such is the consumable part.

      Not special, but I think that the matter is in the low revs and large working volume of the cylinders of marine diesel engines.
      If I'm not mistaken, the first diesel engine was generally intended for the mechanization of mine equipment, and coal dust was assumed as fuel.

      If I don't confuse it this way: fuel oil is used only on the main large engines of ships, ranging from river self-propelled guns to supertankers. At first, these giant marine engines are very low-speed, very deformed. secondly, on the ships there is a whole system of heating, preparation and supply of hot fuel oil to the engine, which is powered by electricity, which is provided by conventional diesel generators on solar oil.

    What makes you think that the Jumo 205 engine is a trophy, the Design Bureau of Junkers-Motoren-Werke, worked in the USSR since 1920 and developed aviation diesel engines, Soviet specialists (the same Charomsky) worked and studied in this bureau, the result of the work of the bureau was production of two samples, V-shaped 12-cylinder (future V-2) and Jumo 205, in 1933, with Hitler's coming to power, the work of the bureau was curtailed, but several samples and documentation of both engines were left to the Soviet Union, and the Germans were V-shaped diesels they were not installed on the aircraft (high specific gravity, low power, low resource), but the Jumo 205 was installed on the Ju-86C in a small batch of the transport version, but then the Germans completely abandoned diesel engines (low specific power, low resource).

      The Ju-86 reconnaissance aircraft, on a diesel engine, flew until the age of 44, an altitude of 12-14 kilometers with a lie, was unattainable for fighters of that time. I came across high-altitude photos of Moscow, 44 years old, from these planes in the internet. Jumo-207 is considered the best aircraft diesel of those years.

          There is a photo of the Baltic states made with a Ju-86 with Yumo 205 engines, ours chased it for 3 minutes, 2 fell out at an altitude of under 10 thousand, the pilots crashed. The third one also fell out but resisted.

      Not only a design office.

      In 1923, the former Russo-Balt plant located on the Filyovskaya floodplain was transferred to the concession of the German aircraft manufacturer Junkers for 30 years for the construction of all-metal aircraft and engines for them.

    Some commentators talk about the aviation past of the B-2 tank with some disdain, they say, tank engineers could not cope on their own. There are several aspects here.


    Hmm ... What does the neglect have to do with it? Kharkov diesel workers really failed. In 1938, their motor did not pass the test. And there were a lot of reasons there, including the battle of vanities of three design organizations at once, which ultimately cost many a career, and some even their lives.

    Firstly, in Kharkov, the experience of diesel engineering consisted exclusively in the construction of low-speed marine engines.


    And nowhere in the USSR was there any experience in the development of tank diesel engines. At all. And no one else.

    Secondly, only the aviators at that time had at least some skills in creating high-speed diesel engines. And high-speed diesel engines for land vehicles have completely different requirements for design, materials, and mass-dimensional parameters. Therefore, it is quite logical that the AN-2 aircraft diesel engine solutions were taken as the basis for the B-1 design. Simply because nothing else was at hand, and the war was already so close.


    And who asked to make a high-speed diesel engine? Nobody asked. This is what the designers decided and did so. And no one took the AN-1 as a basis for the V-2. It's just that after the failure of the Kharkov design bureau in 1938, a whole group of specialists was sent to Kharkov from Moscow, from the Charomsky design bureau to "strengthen". With the requirement to fix it as soon as possible. And in the shortest possible time they actually made the tank AN-1, calling it B-2. It was a serious matter there, the execution was very likely.

    A PDP-diesel with direct-flow blowdown appeared in Kolomna, the author is the chief engineer of Kolomzavod Raymond Aleksandrovich Koreyvo.
    On November 6, 1907, the engine was patented in France, then it was demonstrated at a number of international exhibitions. After these demonstrations, G. Junkers began to produce similar engines and, according to Junkers' drawings, Nobel plants, including those in St. Petersburg. The claim submitted by Koreyvo was not even considered, since this was prevented by the managing director of the Kolomna plant A. Meshchersky, who did not want to quarrel with influential foreigners. In the Soviet Union, diesel engines of such a system began to be used after they got acquainted with the aviation diesel engines Junkers Jumo 205. How the American Fairbanks-Morse diesel engines adapted to the USSR on military boats supplied under Lend-Lease - on their basis, the most massive series of diesel diesel engines 2D100 were created (diesel locomotive TE3) and 10D100 (family of diesel locomotives TE10). Tank engines of the Plant im. Malyshev 5TD and 6TD are built directly according to the Koreyvo scheme.
    After 1917 one of the "Borodino" series motor ships was renamed "Engineer Koreyvo".
