               The development of RD-191 engine was begun at the end of 1998. This engine with afterburning of oxidizer-rich gas is intended for the family of the domestic Angara and Baikal launch-vehicles. The design of this engine also is based on a design of RD-170/171 engines. The RD-191 engine represents single chamber LPRE with vertically located TPU. Within 1999 the design documentation was issued, in 2000 the autonomous development of RD-191 engine units was started, the preparation of production is completed. In May 2001 the first development engine RD-191 was assembled. The first fire test of RD-191 engine was conducted
