Abstract:

A integral manufacture technical of large lengthdiameter ratio composites longtail nozzle was presented in this paper. The choice of materials，design of mould and manufacture techniques were investigated in details. The carbon/carbon throat and copper sintered tungsten nozzle were wound in the middle of longtail nozzle insulation ·Compare with the traditional manufacture technipues，the integral manufacture techniques could improve the production efficiency，quality reliability and integrity and reerosion capability.

Key words: longtail nozzle insulation, tape winding, ablative material, integral manufacture
