- 摘要:
- 随着巡航导弹的作战空域和飞行速度的不断增大，对液体亚燃冲压发动机的性能要求越来越高，亟待对冲压发动机性能的影响因素进行分析研究。通过对液体亚燃冲压发动机的工作过程进行详细的分析研究，编制了冲压发动机性能计算软件，利用该软件分析冲压发动机的各个关键组合件，如进气道、燃烧室、尾喷管以及燃油供应系统等各个组合件的性能对冲压发动机的推力和比冲性能影响程度的大小，以抓住影响发动机性能的主要因素，确定对发动机性能影响最直接的关键组件。计算分析结果表明，对冲压发动机性能影响最直接的因素是可调喷管的冲量效率，对冲压发动机的性能影响也是最大的。此外，涡轮的取气量、燃烧室的燃烧效率对发动机性能的影响也较大。
- Abstract:
- The requirement of performance for liquid ramjet is higher and higher with the constant increase of battle sky and flight velocity of the cruise missile. It is necessary to analyze and research the influence factors on the liquid ramjet performance. According to detailed analysis of liquid ramjet working process, the software of ramjet performance computation is programmed, and each key subassembly of ramjet is analyzed by using this performance calculation software. In order to make sure the primary factors and subassemblies that affects ramjet performance, the affection of every key subassembly (such as intake, combustion chamber, tail nozzle, fuel supply system, and so on) on the thrust and specific impulse of ramjet performance is determined. Calculation and analysis results indicate that the impulse efficiency of tail nozzle is the most direct and important affection factor on ramjet performance. Moreover, air flowrate that drives turbine, and the efficiency of combustion chamber are the more important factors that affect ramjet performance.
