The recently released footage showcases the hot-fire stand tests of RD-107A and RD-108A engines, crucial components utilized in the Soyuz-2.1a and Soyuz-2.1b carrier rockets. These tests rigorously evaluate various parameters such as thrust, fuel system efficiency, turbo pump performance, vibrational stress resistance, temperature tolerance, and time characteristics. Following the tests, the engines undergo disassembly, cleaning, and meticulous preparation for integration with the carrier rockets.
