St. Petersburg, April 8 – RIA Novosti. In the United States, where the Russian RD-180 rocket engines were supplied, they could not determine the composition of the alloy from which they are made, said Mikhail Kovalchuk, president of the research center of the ‘Kurchatov Institute. On Saturday, Kovalchuk delivered an open lecture at Peter the Great Polytechnic University titled “Nature-Like Technologies and Solutions to the Problems of the Modern World.” “Until now, the Americans have been buying our RD-180 rocket engines, … we have been selling them for many years. They take it apart (the engine – editor’s note), assemble it, disassemble it, assemble it, but they can’t make metal,” he said. According to Kovalchuk, difficulties in creating alloys for engine production are typical not only of the space industry, but also of the aircraft industry, which limits notably the number of countries capable of producing fighter engines. . “You, sitting in a wing-winged plane, never think that a turbine is spinning nearby. A turbine consists of many metal blades…it’s such a small piece of metal. and rotates in hot gas at a temperature of more than two thousand degrees … If a blade comes off, the plane collapses or collapses. But (a turbine blade) rotates for several … thousands of hours, the plane flies for many years, and why – because you can make an alloy. So not many people can do it even today,” he told the conference audience. Earlier in June 2022, Roscosmos Director General Dmitry Rogozin reported that the United States has four Russian RD-181 engines for Antares rockets, which launch Cygnus cargo ships to the ISS. Rogozin recalled that the state corporation, in response to US sanctions, stopped the supply of RD-180 and RD-181 rocket engines.
