针对各种温度、压力下，马赫数2．5流场中超临界煤油的超声速燃烧性能进行了实验研究。研制并测试了一个新型二级煤油加热系统，该系统能够把0．8kg的煤油在5．5MPa压力下加热至至950K而不产生严重的结碳。超声速燃烧试验表明，在相同的来流和燃料当量比条件下，超临界煤油的燃烧效率比室温煤油提高10％～15％，与氢气泡雾化的燃烧效率相当。 |

Characteristics of supersonic combustion by injecting supercritical kerosene fuel into a Mach 2.5 crossflow at various preheat temperatures and pressures were investigated experimentally. A two-stage heating system has been designed and tested, which can prepare heated kerosene of 0.8 kg up to 950 K at pressure of 5.5 MPa with minimum/negligible fuel coking. Supersonic combustion tests under the similar stagnation conditions and kerosene equivalence ratios demonstrated that the combustion efficiency when using supercritical kerosene injection increased approximately 10% -20% over that using liquid kerosene injection, while it was comparable to that using effervescent atomization. |
