the chamber walls are often employed, the required protection is
afforded by the propellant itself. These conditions determine the
choice of a suitable chamber material. Since the weight of the combustion
chamber has a decisive effect on the range of the rocket, the
walls should be as thin as possible. The use of thermally insulating
and reinforced (e.g., with fiberglass) inserts made of plastic materials
has already proved successful.
Standard combustion chambers and laboratory combustion chambers*)
have been developed for testing the behavior of solid rocket
fuels and for the determination of their characteristic properties.
Commercial Explosives
Gewerbliche Sprengstoffe; explosifs pour usage industriel
Explosives designed, produced, and used for commercial or industrial
applications other than military.
Compatibility
Verträglichkeit; compatibilité
Ability of materials to be stored intimately without chemical reaction
occurring.
Incompatibility may result in a loss of effectiveness or may be very
hazardous. For example, W Chlorate Explosives and W Ammonium
Nitrate Explosives are not compatible (formation of self-decomposing
ammonium chlorate). For compatibility testing W Vacuum Test.
Compatibility Group
Dangerous goods of Class 1 are to be assigned to a compatibility
group (A to H, J, K, L, N, S) characterizing the kind of good (A to N) or
the hazardous effects (S). A table in the transport regulations containing
the compatibility groups is the basis of the provisions for mixed
loading of Class 1 goods.
Composite Propellants
Verbundtreibsätze; poudres composites
Composite propellants are solid rocket fuels, consisting of oxygendonating
inorganic salts and a binder made of plastic.
