第231章 技术支持(2 / 2)

但是,yf90的前景显然不太乐观。

陪同林炬在这里的,就是曙光计划的总负责人佘院士。

佘院士:“yf77检测结果出来了,12处生产缺陷,7处设计缺陷,六院保证说6个月内解决好,但我还是觉得有些麻烦。”

岂止是有些麻烦!

林炬可是知道,yf77在原世界线,在2019年测试时还发生过故障,也是在这一年才彻底稳定下来,随后老长征五号才迎来了高频次发射时期。

可以这么说,在上个世界线,要不是yf77拖后腿,空间站应该在2020年之前就建成了。

所以虽然现在yf77因为曙光计划的高投入肯定也加大了人员和技术投入规模,但能不能提前三年变得可靠,实在是不好说。

氢氧发动机跟航天局似乎有点八字不合,yf77比冲、推重比、推力三大指标在直接上都显得有些落后,但还是磕磕绊绊,也不知道是哪里卡了。

但佘院士显然是预见了这一点,所以前几天一院就下了个订单,购买1台h240和一台h80。

显然如果yf77实在不够可靠,就用一台h240和一台h80取代长征十号二级和三级的发动机,但这是万般无耐之举,顶多用于第二次发射,后续尤其是正式登月肯定还是得用yf77。

长征十号的最大意义,是航天局用自研火箭把航天员送上月表,每一个字都很重要。

林炬:“新远会全力支持曙光计划,只要我们有的,都可以提供给长征十号,这样吧,如果yf77的设计和材料遇到一些困难,新远或许可以提供技术支持。”

“技术支持?”佘院士有些吃惊。

自从k120以后,新远再没有对外进行任何航天发动机技术交流,也不需要,他们的发动机技术高到惊人,就没见过失败!

但航天局对k120的评价极高,比冲高、推力大、推重比也高,体积还小,简直是一款精致的作品。

k120的潜力也很大,六院评估后认为如果继续提高燃烧室压力,稍稍放大喷管直径,可以发展出200吨级的单燃烧室大推力煤油机,只是这个计划被更强大的yf135取代了而已。

但即使是yf130和yf135,也依然带有k120的血统,可以说是传家宝了。

而对于航天局的技术支持林炬也没有太看重,航天局又不是没实力,而且在他们计划中为长征九号研制的yf90和yf79,尤其是后者闭式膨胀循环氢氧发动机,可以说是同级别世界最先进。

传统技术,就当推一把casa了。
