"Roscosmos" recalled all the engines of the second and third stages of the carrier "Proton-M"

The management of Roscosmos decided to withdraw all engines of the second and third stages of Proton-M launch vehicles to the Voronezh Mechanical Plant (VMZ). The cause of the steel technology problems that were discovered during fire tests, reports Kommersant.

According to newspaper sources, “we are talking about RD-0210 / 0211 and RD-0213 / 0214 engines manufactured by the Voronezh Mechanical Plant: they are installed on the second and third levels of Proton, respectively.”

“The problem was revealed some time ago during the fire tests of one of the second stage engines: according to the results of the investigation of the causes of the incident, it turned out that the assembly of the product used illiquid components,” said the source.

In particular, instead of materials containing precious metals that should be used on this type of engine, “less heat-resistant materials were used, which are used in other types of engines produced at VMZ,” the article says.

This fact did not go unnoticed by law enforcement. Now the company employs employees of the FSB and the Investigative Committee.

“According to the documents signed by the inspectors, the engines are in perfect order,” one of the sources specified.

The decision to recall the engine made 20 January. “We are talking about all without exception engines for“ Protons ”, released at VMZ over the past few years. These are dozens of units, including those that have already been delivered to the Baikonur cosmodrome, ”said the source.

According to a source close to Roskosmos, “they corrected the situation at Vyksa with the Energomash Research and Production Association,” since it is believed that the situation with the quality and reliability of the engines produced is much higher.

“The contour of the integrated structure headed by Energomash includes the Chemical Automation Design Bureau, which is the developer of engines for the second and third stages of Proton launch vehicles and thoroughly knows the technical characteristics of the engines and the specifics of their manufacture. To remedy the situation that has developed at VSW, as part of the industry reform carried out by Roskosmos, we will conduct an audit and additional technical control of all engines that have already been produced at VSW, ”said Igor Arbuzov, general director of Energomash.

According to him, this measure "will accelerate the identification of the causes of the detected defects, their elimination and may lead to changes in the timing of launches of Proton and Soyuz launch vehicles."

According to the newspaper, this year, Roskosmos hoped to conduct 27 launches, no less than 8 of which fall on the Protons.

Yes, that's right, because GOST is a State mandatory standard that must be strictly observed! And TU-is an internal document at this enterprise or a departmental document into which, at the request and man-made need, changes and additions are made. We need, for example, alloy steel, and we accept changes in the technical specifications and stick some other one instead. I flew well, I didn’t fly, so here it is.

Here I do not understand! After all, in order to replace the material laid down by the designer with another one, it is necessary to issue a "Replacement Sheet", on which you need to collect a bunch of signatures - a designer, a technologist, a metrologist, a quality control department, suppliers, CIS and many others. If replaced without "Liszt" - this is a matter of jurisdiction, if with "Liszt" - to disperse all the signers, and also on trial for sabotage. But it looks like this situation has been dragging on for several years. I don't understand how this could have happened!

[Skeptic Self-Taught]

You do not swear with words like "Replacement Sheet" - USE graduates will not understand you unambiguously.
How did this situation happen? Yes, everything is simple - a supply graduate sits. who buys material from the same graduate manager. And they don’t understand that replacing one material with another is not a replacement for buttons on shorts. from actually all.

No, I think it’s not a matter of professionalism, it is a matter of rubles. I have already cited an example with our metro, where to save titanium bolts with alloy steel they were replaced, saving damn it, some burst, with the consequences, by the way, they did not build the metro in the city. They have been digging since the days of the USSR, and even now they promised to launch a short branch for the 300th anniversary of the city ... now we have the shortest metro in the world from one station used as an underground pedestrian crossing.

Yes, there is no need to be a specialist. GOST is a STATE standard, mandatory for all to whom it relates. And TUs are their internal standards for a particular company.

You are in many ways wrong. No need for interrogations with addiction. You just need to simply introduce the previously withdrawn military acceptance in the entire technological chain of production of both the product as a whole and all the elements. Manufacturers in the workshop, of course, will not, at their own peril and risk, change material or technology. In my time, this was formalized by Permission Cards, signed by everyone, from the designer to the head of the Quality Department and the military representative. And everyone had the right not to accept such an assumption. Even me, a simple lead constructor. No living soul could force me. What to speak of higher authorities, the Chief Engineer, and the Military Representative. The decision to start production was made only when the Military Representative received a certificate of complete equipment with both purchased and materials in the warehouse of the plant. EVERYTHING was checked. And at any stage he had the right to stop production. The notice was sent both to his military authorities, and to our ministry. Such products were recorded in the Plans of the Military-Industrial Commission, as well as, naturally, in the ministry, and the minister did not receive an enema for disruptions. The system worked perfectly.

Well, made a noise, and now a little different information.

In particular, instead of materials containing precious metals that should be used on this type of engine, “less heat-resistant materials were used, which are used in other types of engines produced at VMZ,” the article says.

The analysis showed that during the production of the Proton-M launch vehicles, solder was used that did not correspond to the design documentation. “In December 2016, the next tests of the second stage Proton-M engine were carried out. According to the test results, there are no comments on the operation of the engine. A detailed analysis revealed the use in the production of solder that does not correspond to the design documentation, "RIA Novosti quotes a message from Roscosmos.
Instead of the standard one, another, "more expensive solder with precious metal content" was used. “Since the discrepancy between the product and the design documentation was revealed, a decision was made to check the engines,” the state corporation said. "At present, specialists from Roskosmos, VMZ and NPO Energomash are working on determining the number of engines in which this solder is also used," the company said. All defective engines will be replaced. Roskosmos did not say how many engines could be recalled.

Refresh the waste paper in your head. At first they wrote about the printing of engines, and so fast that they fit in two days, now, it turns out only this powerful detail. Different sections of your mindset conflict with each other.

And what is it customary to be rude to go without understanding?
Well, if you need to chew everything, then please: I wrote about printing an engine in two days as an example - to show that new technologies can simplify production many times over. With the resources of Roscosmos, they should have implemented it a long time ago. And yes - the desk is small, so they make small engines. Roscosmos could do this on a larger scale.
I gave a second example of the real use of 3D printing to show that the large and most important elements of the engine ALREADY print, and these engines ALREADY fly. The combustion chamber is the most critical element of the engine, which is subjected to maximum temperature load.
Now hopefully understand?

During the fire tests, the nozzles of the gas generator burned out. The gas generator worked out the prescribed time. They began to look for the cause and found a substitute for the solder. An error occurred while receiving the solder in the pantry. The solders were silver but had different contents of poladium. Visually they could not be distinguished. They put the most expensive solder. Determine which engine it’s worth a gas generator with such solder cannot. Therefore, all the engines are removed. This is such an expensive mistake. According to Progress, the plant was found guilty as the plant was not unlocked. And the problem at the plant is the lack of sensible organization and management. Like everywhere in the country.

There is also such a problem in the defense industry as procurement by tender. Simply put, you receive material, according to the certificates you need it, but when you start the technical process, nothing happens. You can already say from your own experience that the supplied material is guano, but in chemistry. you cannot give the analysis! There is no reason, because the certificate. Because we admit that the certificate is a linden, and bought a full "ge" NIZZya, otherwise the nephew / matchmaker / godfather / brother will be guilty. It's easier to say that you don't know how to work in the shops. And the departments for quality management, lean production and compliance with environmental standards are multiplying, and technologists are normal and high-class workers, they finish working up to retirement and leave, and who are retired, they do not sign a new contract because they are tired. So now the simple worker will again be the guilty person on duty.
