In order to maintain the design point of compressor,total temperature,total pressure and mass flow before the guide blade,and total pressure of turbine outlet is raised by using spacial twisted and bowed guide blade,so that the thrust may be improved by reducing the nozzle throat area.

Design of automatic die carrier for assembling the bushings into guide sleeve;

Antifrictional & wear-resistant and low shrinkage Nylon composite for guide sleeve was prepared by means of blending antifriction & wear-resisting agent, talcum powder and PA6.
