Что-то мне тревожно
По данным телеметрии «Наука» подозреваются неисправности в топливной системе.
Российский модуль "Наука" (МЛМ-У), успешно запущенный вчера с космодрома Байконур и выведенный на целевую орбиту, обнаружил неисправность в топливной системе, сообщил N + 1 источник в ракетно-космической отрасли. Для выхода на орбиту и сближения с МКС «Наука» должна четыре раза включить двигатели; По его словам, из-за сбоя модулю может не хватить топлива для всех маневров. В пресс-службе Роскосмоса сообщили, что новых данных о состоянии МЛМ пока нет, информация о первой попытке включения двигателей может поступить после 15:00.
According to telemetry "Science" suspected malfunctions in the fuel system
The Russian module "Science" (MLM-U), which yesterday successfully launched from the Baikonur cosmodrome and injected into the target orbit, encountered malfunctions in the fuel system, said N + 1 a source in the rocket and space industry. To raise the orbit and approach the ISS, "Nauka" must turn on the engines four times; due to a failure, the module may not have enough fuel for all maneuvers, he said. The press service of Roscosmos reported that there is no new data on the state of MLM yet, information about the first attempt to turn on the engines may come after 15:00.
The Nauka module, which was originally created as a backup for the Zarya module, is to become the main platform for scientific experiments under the Russian program. He was supposed to fly to the station back in 2009, but the launch was repeatedly postponed for several reasons. Chief among them, causing the longest delay, is a manufacturing defect that left metal shavings in the fuel system. Removing it from the tanks and pipelines turned out to be a difficult technological task, we talked about this in more detail in the large material "Fatal shavings" .
The reason for the appearance of shavings was partly in the very design of the tanks: inside them there were thin steel "accordions" - bellows, which in zero gravity provide pressure in the tanks. After long attempts to get rid of the shavings, the specialists decided that it would not create problems if the tanks did not need to be refilled, and this operation would not be required after the module reached the ISS.
According to the source of N + 1 , judging by the telemetry information, too high pressure was created in the fuel system, as a result of which the bellows broke and the fuel flowed into the gas cavity behind the bellows membrane. This means that some of the fuel may not get into the pipelines and engines, which, in turn, jeopardizes the ability to reach the ISS. On the other hand, the source notes, similar telemetry data can create malfunctions in the fuel system valves.
According to him, the situation remains unclear, some time ago the engines were turned on for the first time on board the module, but it is still unknown whether the activation was carried out normally.
An indirect confirmation of the problems with MLM can be the information about the transfer of the Pirs undocking from the docking station, where the module is to be docked. It was originally planned for Friday evening, now, judging by the negotiations of the crew , it could be postponed until Saturday.
