The rocket is launched using liquid hydrogen and liquid oxygen cryogenic propellants. Rocket propellant is used as reaction mass ejected from a rocket engine to produce thrust . The energy required can either come from the propellants themselves, as with a chemical rocket , or from an external source, as with ion engines .

However, strontium was identified to be present in the red flares and signaling fireworks available in 2014. Due to these finding, the developers of the environmentally friendly red-light flare concluded that the development of environmentally safer flares was a necessity for users.
The GIRD X rocket was launched on 25 November 1933 and flew to a height of 80 meters. [24] In 1933 GDL and GIRD merged and became the Reactive Scientific Research Institute (RNII). At RNII Gushko continued the development of liquid propellant rocket engines ОРМ-53 to ОРМ-102, with ORM-65 powering the RP-318 rocket-powered aircraft. [18]
