This article is mainly on developing a new pyrotechnic exhaust composition, which can efficiently extend range to the base bleed. The main component is obtained from the choice of oxidant, fuel, binder and additive of contained energy. The effects of combustion temperature, combustion rate are discussed from the measurement result of different formulae which burn on the condition of quiescence and rotating, and then a good composition is selected. And the mechanism reducing base resistance is studied in depth, the technology way reducing base resistance is discussed in theory. And then, the dissertation probes into the combustion law of the pyrotechnic exhaust composition, formula of combustion rate is inferred. |
