| 摘 要： | 为了降低低温推进剂损耗，提高利用效率，降低发射成本，提出了4套运载火箭低温推进剂地面加注系统的冷量利用方案。基于热力学原理，建立了非稳态数学模型，并以能量品质高低作为衡量方案优劣的标准，通过实例计算对比分析了各个冷量利用方案的可行性。研究得出4套冷量利用方案从热力学角度出发都是可行的，其中方案A和方案D最优，方案A可应用在目前现有低温推进剂地面加注系统中，而方案D则可应用于未来重型运载火箭低温推进剂地面加注系统之中。

| Abstract: | In order to decrease loss of cryogenic propellants, enhance utilization rate, reduce launch cost, four schemes of cooling capacity utilization are proposed. Based on the principle of thermodynamics, unsteady mathematical model is developed. With energy quality as criteria of evaluating schemes, each scheme of cooling capacity utilization is comparatively analyzed by example calculation. The study shows that four schemes of cooling capacity utilization are all feasible from the angle of thermodynamics, of which the scheme A and the scheme D are optimal. The scheme A can be applied into the present ground loading systems of cryogenic propellants, and the scheme D can be applied into the future ground loading systems of cryogenic propellants for heavy launch vehicle. |
