多孔介质控制整装式含能液体燃烧稳定性的研究

设计了整装式含能液体燃烧推进模拟实验装置,采用可燃性多孔介质填充于液体发射药燃烧室中,开展了整装式舍能液体燃烧推进试验研究.结果表明:多孔介质可以控制整装式含能液体的燃烧稳定性,但与液体发射药的装填密度有关.当液体发射药的装填密度约0.52 g/cm3时,燃烧过程稳定,p-t曲线光滑;当液体发射药的装填密度大干O.58 g/cm'时,可观察到明显的压力振荡现象,且装填密度越大,压力振荡越强.

Study on Combustion Stable Control of Bulk-loaded Energetic Liquid by Using Porous Media

A simulated test device of combustion and propulsion of bulk-loaded energetic liquid is designed, the experimental research on combustion and propulsion of bulk-loaded energetic liquid filled by combustible porous media is developed. The results show that the porous media cancontrol the combustion stability of bulk-loaded ener-getic liquid, but it is related to loading density of liquid propellant. When the loading density is about 0.52 g/cm^3,the combustion process is stable, the p-t curves are smooth. When the loading density is more than 0.58 g/cm^3 , the pressure oscillation phenomenon is observed, with the increasing of charge density, the pressure oscillation is stronger.
