The mechanical properties of the aviation kerosene gels with hydroxypropyl cellulose as a gelator are studied by using a soft-solid tester. It is found that the contents of the components excepting the solvent and the gelator,including surfactants,stabilizers and other additives influence the yield stress of the gels significantly. The yield stress increases along with increasing the concentration of the gelator or that of the surfactant,OP-10. Introduction of the stabilizer C accelerates the formation of the gels and improves the performance of the gels subject to shear force.
