The development of a concept design for assembling elements of spacecraft in orbit (hereinafter - the development of the Soyuz rocket and space complex) was prescribed by Resolution of the Central Committee of the CPSU and Council of Ministers of the USSR dated April 16, 1962 N 346-160.
Aerodynamic, structural tests, as well as studies of the heat and mass transfer of the ship and the entry body were carried out in the NII-88/TsNIImash.
The works carried out at the institute made it possible to engrain a number of recommendations for improving the aerodynamic and design parameters and for optimizing the low-conductivity coatings of landers. Structural (vibration and static) tests for the development of the Soyuz spacecraft, and then Soyuz M, Soyuz T, and Soyuz TM were conducted at TsNIImash in 1965, 1966, 1973, 1974, and in 1987-1989. The suite of strength studies of the Progress SC layout was run in 1988-1989 for the mockup of the new Progress M ship at the test facilities of TsNIImash in 1975-1976.
