基于设计体系的高性能多级压气机综合设计技术

综合设计技术在压气机设计中的作用极其重要.压气机设计体系建设取得了很大进步,但目前尚没有1种设计体系能够自动完成高性能多级压气机设计,为此,需要设计者在设计中掌握并能够灵活运用综合设计技术.应用综合设计技术完成2个成功设计实例:改进设计20世纪80年末期的某4级轴流压气机的第2级,使整机绝热效率提高2.4％;21世纪初期综合运用已有设计技术完成整机绝热效率达0.9的某型5级轴流压气机设计.分析表明:设计者只有掌握了综合设计技术并能够熟练运用已有的设计体系,才能够充分发挥设计体系的重大作用,从而设计出理想的高性能压气机.

Integrated Design Technique of High Performance Multistage Compressors Based on Design System

The role of integrated design technique is very impotant in compressor design. Although much progress has been made on the design system, there is still not such a system that is able to perform a high performance multistage compressor design automatically. So the designer must master and use flexiblely the integrated design technique. Two successful design cases include overall adiabatic efficiency advancing 2.4 percent by modifying the second stage of a four stage axial compressor of the 1980s and adiabatic efficiency 0.90 obtained by five stages in 21st century. The analysis indicate that only if the designer master the integrated design technique and can use expertly the design system, the system can be made the best of in ideal high performance compressor design.
