An entry appeared on the official website of the state corporation Roscosmos that the S.P. Korolev Rocket and Space Corporation Energia (part of the state corporation) received a patent for the latest single-turn scheme for the flight of spacecraft to the International Space Station. The introduction of this scheme will allow manned or cargo ships to reach the station in just two hours, which is much faster, cheaper and more efficient than the four-turn scheme.
“We were issued a patent, since November 12 it has been included in the register of state inventions of the Russian Federation,” said Rafail Murtazin, head of the ballistics department of RSC Energia.
It is worth noting that space specialists from Russia have already begun working out the necessary elements for a single-turn system – the technology was tested during the flight of the Progress MS-17 cargo spacecraft, which went to the ISS in June-July 2021. Naturally, this is not the end of the development of the new scheme – they plan to continue testing it in June 2022 during the launch of Progress MS-20.
“We will prepare the conditions for carrying out a four-turn rendezvous scheme for the Progress MS-20 and, against its background, we will work out the elements of a single-turn scheme,” Murtazin added.
At the same time, according to the statements of Vladimir Solovyov, the general designer for manned space systems and complexes, the Progress single-turn flight scheme to the International Space Station is planned to be fully implemented from the beginning of 2023. Previously, starting in 2012, the Progress ships flew to the station in a four-turn scheme, which takes as much as six hours to reach the target. Prior to this, a 34-turn circuit was used, which took two whole days. Only in 2018 did the two-turn scheme come into play – it requires three hours for delivery to the ISS.
