摘要：

For better combustion characters of rocket engine, the combustion performance of four high-energy-density liquid fuels and nanofluid fuel containing nano-sized aluminum particles were studied by using a model rocket engine. The combustion efficiency, mass / density specific impulse, ignition delay time, and the combustion products of nanoparticles were analyzed. The results show that in the air-to-fuel ratio of 1.6~2.0, the combustion efficiency and mass specific impulse of the four liquid fuels are in the order of QC>HD-01>HD03≈LGHD-03, whereas the density specific impulse is in the order of QC> HD-03≈LGHD-03>HD-01. In particular, QC shows outstanding propulsion performance because of the high density, high energy and high reactivity derived from its unique strained molecular structure. QC shows combustion efficiency of 91.5%, mass and density specific impulse of 230s and 2276N•s/m3 respectively. When 15wt% nanosized Al particles are added in QC, the combustion efficiency and mass specific impulse are decreased slightly, but the density specific impulse increased to 2340N•s/m3 and the ignition delay was shorted by 26ms. The solid product after the combustion contains carbon, Al2O3 and Al, with the combustion efficiency of Al as about 91%. QC containing Al NPs is a potential high-density liquid fuel. © 2019, Editorial Department of Journal of Propulsion Technology. All right reserved.
