在传统的再生冷却超燃冲压发动机中，燃料在冷却后直接进入燃烧室。本文提出，从第一冷却通道出来的高温高压燃料通过涡轮膨胀，将燃料的焓传递给工作后，可用于二次冷却。因此，反复使用燃料散热器（冷却能力）来间接增加燃料散热器。代替携带多余的燃料用于冷却或寻找任何新的冷却剂，用于冷却的燃料流量减少，并且机载燃料足以满足整个高超声速飞行器的冷却要求。首先定义了冷却和膨胀，其次定义了超燃冲压发动机的开放式冷却循环（OCC）。本文简要介绍了利用基本热力学原理对超燃冲压发动机OCC的性能潜力和科学可行性进行评估。结果表明，由于燃料散热器的增加和额外的功率输出，OCC比再生冷却产生更高的性能增益。
Abstract In a conventional regeneratively cooled scramjet, fuel directly enters the combustor after cooling. It is proposed in this article that high-temperature and high-pressure fuel out of the first cooling passage can be used for secondary cooling after expanding through the turbine and transferring enthalpy from fuel to work. A fuel heat sink (cooling capacity) is thus repeatedly used to indirectly increase the fuel heat sink. Instead of carrying excess fuel for cooling or looking for any new coolant, the fuel flow for cooling is reduced, and fuel onboard is adequate to satisfy the cooling requirement for the whole hypersonic vehicle. First are defined cooling and expansion and, second, cooling an open cooling cycle (OCC) for the scramjet. This article provides a brief description of the assessment of the performance potential and scientific feasibility of a scramjet with OCC using fundamental thermodynamic principles. The results show that OCC yields higher performance gain over regenerative cooling, because of the increase in the fuel heat sink and additional power output.
