The RD-215 (GRAU Index 8D513) was a dual nozzle liquid rocket engine, burning AK-27 (a mixture of 73% nitric acid and 27% N2O4 + iodine passivant) and UDMH. It was used in a module of two engines (four nozzles) known as the RD-216 (GRAU Index 8D514).[2] The RD-215 was developed by OKB-456 for Yangel's Yuzhmash R-14 (8K65) ballistic missile. Its variations were also used on the Kosmos-1, Kosmos-3 and Kosmos-3M launch vehicles.[1]
Versions
The family incorporate many versions:[1][7]
- RD-215: GRAU Index 8D513. Original design for the R-14 (8K65). Used also on the Kosmos-1 and Kosmos-3[2][1]
- RD-215U: GRAU Index 8D513U. Improved engine for the R-14U (8K65U).[1]
- RD-215M: GRAU Index 8D513M. Improved version used on the Kosmos-3M.[1]
- RD-217: GRAU Index 8D515. Modified design for the R-16 (8K64) first stage.
- RD-219: GRAU Index 8D713. Modified design for the R-16 (8K64) second stage.
Modules
These engines were bundled into modules of pairs of engines. The serial production modules were:[1][3]
- RD-216: GRAU Index 8D514. Bundle of two RD-215, used on the R-14 (8K65), Kosmos-1 and Kosmos-3 first stage.[2][1]
- RD-216U: GRAU Index 8D514U. Bundle of two RD-215U, used on the R-14U (8K65U) first stage.[1]
- RD-216M: GRAU Index 8D514M. Bundle of two RD-215M, used on the Kosmos-3M first stage.[1]
- RD-218: GRAU Index 8D712. Bundle of three RD-217, powers the R-16 (8K64) first stage.
