Nomenclature rules for composite solid propellants (English Version)
As an upgraded version of the 1987 version of the standard, GJB 325A-2021 reflects the important development of binder systems and oxidizer combinations in the field of composite solid propellant technology in my country. The main technological evolution is reflected in:
Comparison dimensions | GJB 325-1987 | GJB 325A-2021 |
---|---|---|
Binder categories | 4 categories | 7 categories (newly added azide propellants, etc.) |
Code structure | Two-level numbering | Three-level numbering (adding modification serial number) |
Characteristic components | 3 standard combinations | 5 standard combinations + other categories |
The standard stipulates that the propellant code adopts the three-section structure of A-BC-DE:
A research institute developed a binder system.
Numerical code | Binder type | Typical application |
---|---|---|
404 | Polyether | Tactical missile booster |
413 | Azide | High-energy solid rocket |
410 | Hydroxybutyl | Booster stage of launch vehicle |
