Abstract: |
In this paper a reasonable technological programme and measures were established aiming at the structural characteristics and technical difficulties of inner-tailpipe nozzle of turbo fan engine. Forming process was optimized with numerical simulation software. Forming die, welding and electrical discharge machine special toolings were designed. Key technologies of inner-tailpipe nozzle were solved, and qualified products were produced. |
