液体二茂铁衍生物系高燃速催化剂，具有良好的催化效果和热稳定性。以２，２－双乙基二茂铁丙烷（ＢＥＦＰ）与利用气流粉碎机制造的极细高氯铵（ＶＦＡＰ）为基础试制了高燃速高能推进剂。采用这种ＶＦＡＰ的推进剂，在燃烧压力为５ＭＰａ时燃速可达２０ｍｍ／ｓ，但压力指数升高。而采用ＶＦＡＰ与ＢＥＦＰ组合时，燃速可提高到４０ｍｍ／ｓ以上，且压力指数可降低到实用值。分析了ＶＥＡＰ的结晶及热分解特性，与平均粒度为０．１μｍ的超细铝粉（ＵＦＡｌ）和银丝组合，试制出可以直接浇注的燃速为１５０ｍｍ／ｓ以上的高燃速高能推进剂。
Liquid ferrocene derivatives are high burning rate catalysts with good catalytic effect and thermal stability. A high-burning-rate, high-energy propellant was developed on the basis of 2,2-bis-ethylferrocene propane (BEFP) and very fine ammonium chloride (VFAP) manufactured by a jet mill. Using this VFAP propellant, the combustion rate of 5MPa burning rate up to 20mm / s, but the pressure index increased. With VFAP and BEFP combination, the burning rate can be increased to 40mm / s or more, and the pressure index can be reduced to a practical value. The crystallization and thermal decomposition characteristics of VEAP were analyzed. In combination with ultrafine aluminum powder (UFAl) and silver wire with an average particle size of 0.1μm, a high burning rate high energy propellant with a burning rate of over 150mm / s .
