数值仿真技术在航空动力研制中的地位和作用

Position and function of numerical simulation technology in aero-engine development

针对先进航空发动机的技术发展需求,提出了航空发动机数值仿真技术的定义和内涵。从专业、学科、空间、时间、工具等方面给出了航空发动机数值仿真技术的五个维度,从促进航空发动机研制模式转变等方面分析了其战略地位和作用。通过国外典型研究计划和实例分析了国内外发展现状,指出了我国在该技术领域的主要差距。提出要充分认识数值仿真技术在航空发动机研制中的重要地位和作用,尽快建设和发展属于我国自己的航空发动机数值仿真系统,建设面向全行业的“航空发动机数据库”。

The definition and implication of numerical simulation technology were proposed based on the technical development requirements of advanced aero-engines development.The dimensions of aeroengine numerical simulation technology were studied from specialty,discipline,space,time and tools,while the strategic position and function in promoting the transformation of aero-engine development method were analyzed.The disparity of numerical technology for aero-engine at home and abroad was discussed by analyzing the development status of typical foreign research plans and projects.It is proposed to fully understand the important position and function of numerical simulation technology in the aero-engine development,and to build and develop our own aero-engine numerical system and industry-wide “aeroengine database” as soon as possible.
