Thus, the RD-0107 was developed in the 1960 to 1961 period, based on the RD-0106 (GRAU Index: 8D715) engine that powered the SS-8 Sasin ICBM, also designed by OKB-154.

[4][10] For the crewed carrying Voskhod Block-I, a version of the engine that complied with the human rating 3K Regulations was needed.

A particular problem observed during acceptance testing were high frequency instabilities, particularly during the start sequence.

This allows it to work at relatively low inlet pressures without requiring additional booster pumps.

Even though the start instabilities were relatively rare at 1 in 60 to 80, and only on acceptance bench, great effort was made to eliminate the issue.

The lower section of the nozzle has no external lining, exposing the corrugated jacket to save weight.

Given the extreme temperatures at the throat section, this part is made of copper alloy with milled channels and an external lining.

A separate film cooling system is implemented though a different manifold and is injected though a circular slot upstream of the throat.
