The ORM-52 liquid rocket engine was developed in 1933 at the Gas Dynamics Laboratory led by Valentin Glushko. It became one of the most powerful high-thrust engines in the early ORM series. It worked on a mixture of kerosene and nitric acid, and developed quite a significant thrust for its time — 300 kgf. Because of this, the ORM-52 engine was used in one of the first experimental liquid-propellant rockets — RLA-2. According to the project, the rocket had to rise vertically, reach an altitude of 4 kilometers and then release a parachute with meteorological instruments located on its head. On the wave of success of the ORM-52 engine, some more powerful liquid rocket engines were developed after a series of tests: from ORM-53 to ORM-70, which could produce up to 600 kgf of thrust.
