摘要
Abstract
To reduce the erosion of R2 high-energy propellant,a new composite erosion inhibitor based on silicon/modified na-no TiO2/paraffin was designed and prepared.The erosion-reducing performance of the new type of composite erosion inhibitor was studied by a semi-closed bomb test with the standard erosion inhibitor as the reference material.The erosion inhibition mechanism of the new composite erosion inhibitor was studied by scanning electron microscope-energy dispersive spectrum(SEM-EDS),and its effect on the static combustion property of propellant was investigated using a closed bomb test.The results show that the new composite erosion inhibitor has a significant effect on reducing erosion.The erosion inhibition rate can reach 34.24％when the addition of erosion inhibitor is 5％.Decamethylcyclopentasiloxane(D5)in the erosion inhibitor is decom-posed at high temperature,and the silicon oxide nanoparticles produced by the decomposition can effectively block the carburi-zation reaction by adhering to the inner wall of the erosion tube.Since R2 propellant added with the new composite erosion in-hibitor has higher combustion progressivity,the energy is released at the later stage of combustion which is beneficial to reduce the erosion.关键词
