Korolev's key partner in shaping the R-7's packet design
On 21 August 1957, the R-7 whose design Kryukov helped shape finally completed its planned flight.
Sergei Kryukov was a Soviet rocket and space-technology designer who helped define the R-7's overall form and its packet arrangement of four strap-on blocks around a central stage. If Korolev directed the programme as chief designer, Kryukov turned its concept into an integrated structure and working design through the project department he led. He later directed automated interplanetary-station and launch-vehicle work at the Lavochkin bureau and Energia. His career shows that the space programme was built not by a lone genius but by specialised collective design and production systems.
