The advantages of the process are processing error and thermal deformation is small, standard capability is strong and the repaired nozzleperformance is clearly superior.
该工艺的优点是加工误差小、热变形小、规范性强、修复后的喷嘴性能明显优越。

It is shown that aerospike nozzleperformance losses caused by free stream primarily result from increase of lift body base drag and decrease of plug pressure distribution.
结果表明，外流造成的性能损失主要体现在运载器底部阻力增加和塞锥表面压强降低两方面。

The experimental results indicate that the tile shaped aerospike nozzle has good altitude compensation ability, and that the proper base bleed can promote the nozzleperformance.
