摘要： 为了研究凝胶燃料的流变机理和配方设计的基础理论，根据凝胶特殊的固-液形态，寻找凝胶化航空煤油RP-1需要的无机和有机凝胶剂，对其成胶机理、流变表征和稳定性进行研究，通过Brookfield流变仪测量流变参数，并构建出无机和有机煤油凝胶的HBE本构方程。结果表明:采用高速剪切分散比三辊研磨分散制备的无机煤油凝胶质量好；加入无水乙醇有利于凝胶剂A对煤油的凝胶化；无机煤油凝胶的物理稳定性受凝胶剂含量影响显著，实际应用选择6%和7%无机凝胶；所制备的煤油凝胶比典型的剪切变稀流体(0

Abstract: In order to research the basic theory of the rheological mechanism and formula design of the gel fuel，according to the special solid-liquid state of gel，inorganic and organic gel agents for gelation aviation kerosene RP-1 are searched and then the gelation mechanism，rheological characterization and stability are studied. Finally，the rheological parameters are measured by Brookfield rotational rheometer and the HBE constitutive equation is built. The results show that，the inorganic kerosene gel made by high speed dispersion has better quality than that made by three-roller grinding. The anhydrous ethanol is advantageous for the gelation of kerosene by gel agent A. The physical stability of the inorganic kerosene gel is affected by gel content significantly，6% and 7% inorganic gel will be chosen for use. The thinning ability of the kerosene gel prepared is stronger than that of the typical shear thinned fluid(0
