| 摘 要： | 利用热力学第二定律的功势指标之一的推力功势,推导出了航空燃气轮机各部件的推力功势效率的表达式,分析了各种参数对推力功势效率的影响,提出了一个各种效率具有"同时归一"性的准则,从理论分析和数值计算上纠正了文献[2]中的一个错误。研究结果表明:推力功势效率不仅与部件效率有紧密的自然关系,还与其它热力参数(如压比)有内在的逻辑关联,与部件效率不同的是,推力功势效率更能从能源转化为有用功的角度统一地衡量航空燃气轮机的部件性能,为进一步研究各型航空燃气轮机的能源转化和利用的性能奠定基础。

| Abstract: | By using the thrust work-potential,one of the work-potential indexes in the second law of thermodynamics,derived was the expression of the thrust work-potential efficiency of various components in an aero gas turbine with the influence of various parameters on the above efficiency being analyzed and a criterion for tending to be one simultaneously of various efficiencies being proposed. As a result of the theoretical analysis and numerical calculation,an error in the reference literature [No.2] was correcte... |
