QJ 20021-2011 (English Version) PDF

Scope: This standard specifies the general requirements, test preparation, test procedures and test result processing requirements for altitude control engine gas (nitrogen, air) injection high-altitude simulation tests. This standard is applicable to the gas ejection high-altitude simulation test of the storable propellant liquid rocket attitude control engine (hereinafter referred to as the engine). Attitude control engines such as air-conditioning, solid and gel can also be implemented by reference.
