High energetic nanoparticle as additives is of great significance for liquid hydrocarbon fuels that will exhibit high heat value and potential performance improvement in hypersonic and related combined circle propulsion system. In the study, the JP-10 slurry fuel containing 16 wt% aluminum nanoparticles was experimented upon a scramjet engine to investigate the combustion efficiency and engine performance in comparison to pure JP-10 fuel. It is the first to realize the stable combustion of hydrocarbon fuel containing nanoparticles in scramjet engine. The wall pressure profile and calculated Mach number along the combustor are firstly compared and analyzed with the equivalence ratio of 0.56, 0.73 and 0.91. At the equivalence ratio of 0.56, the addition of aluminum nanoparticles promoted the engine to transition from the scramjet mode to the dual-model ramjet mode in advance, and the wall pressure along the combustor path to increase significantly. The combustion efficiency data of the two fuels are calculated by one-dimensional impulse analysis method. The results show that the combustion efficiency of slurry fuel is significantly higher than that of pure fuel. Besides, the addition of aluminum nanoparticles also enhanced the density specific impulse. When the equivalence ratio is 0.56, 0.53 and 0.91, the density specific impulse of slurry fuel increases by 34.37%, 11.33% and 8.96% respectively. The above research indicates that the use of slurry fuel containing aluminum nanoparticles indeed improves engine performance and has great potential in engineering applications.

高能纳米粒子作为添加剂对液态烃燃料具有重要意义，液态烃燃料将在高超声速及相关的联合循环推进系统中表现出较高的热值和潜在的性能改善。在这项研究中，在超燃冲压发动机上对包含16 wt％铝纳米颗粒的JP-10浆状燃料进行了试验，以研究与纯JP-10燃料相比的燃烧效率和发动机性能。这是第一个在超燃冲压发动机中实现包含纳米颗粒的碳氢燃料稳定燃烧的方法。首先对当量比为0.56、0.73和0.91时沿燃烧室的壁压力曲线和计算出的马赫数进行了比较和分析。在当量比为0.56的情况下，铝纳米颗粒的加入促进了发动机提前从超燃冲压发动机模式过渡到双冲压冲压发动机模式，并且沿燃烧室路径的壁压显着增加。通过一维脉冲分析法计算两种燃料的燃烧效率数据。结果表明，浆料燃料的燃烧效率明显高于纯燃料。此外，铝纳米颗粒的加入也增强了密度比冲量。当当量比为0.56、0.53和0.91时，浆料燃料的密度比冲量分别增加34.37％，11.33％和8.96％。上述研究表明，使用含铝纳米颗粒的浆料燃料确实可以改善发动机性能，并在工程应用中具有巨大的潜力。
