困扰中国多年仅次核武的第二大敏感技术,有盼头了!

2017-09-27 09:14:26   瞭望

美国航空发动机工业,之所以能克服重重困难、走在世界前列,与重视预先研究是分不开的。

现役装备必须考虑技术风险,预先研究是一个“试错”的过程,其意义在于发现新技术中可能存在的风险,从而克服风险。

然后,将有价值的技术储备下来,推动其进入实用阶段。

但是,由于前沿技术的不确定因素较多,因此,预研失败概率很高,投资风险也大。

可贵的是,美国人顶住了这种压力,允许“失败”,并且,不放弃失“失败”。

就这样,一些“失败”了的项目起死回生了。

如通用电气的YF120,它在F-22动力竞标中败北,但因为美国政府和军方的支持和呵护,没有死掉。

YF120失利的重要原因是采用了太多新技术,缺乏足够的验证。

军方并未就此放弃,而是通过IHPTET(综合高性能涡轮发动机技术)项目与通用电气展开合作,帮助YF120的诸多先进技术走向成熟。

F22战机的标准动力F119发动机正在测试

在IHPTET计划支持下,普·惠和通用电气等企业开发和验证了一大批先进的核心机技术,其中涉及涡扇、涡轴以及用于武器的小型一次性喷气发动机等诸多领域。

通过这项计划,美国的航空喷气发动机预研技术始终跟现役技术保持着合理的时间间隔,互相配合、互为依托,从而确保了技术领先优势。

“中国心痛”的四大病因

美国国家关键技术部计划说明书上这样写道:

“航空发动机是一个技术精深得使新手难以进入的领域,它需要国家充分开发、保护并充分利用该领域的成果,需要长期的数据和经验积累,以及国家大量的投入。”

确实,航空发动机作为尖端技术,仅凭行业部门的研发是远远不够的——如果没有国家的战略规划、大量投入、长期的数据和经验积累、以及核心技术保护和充分利用其成果,要想一蹴而就是不可能的。

回首中国,航空发动机也一直是困扰中国飞机的“心脏病”,我们的问题主要在于:

第一,缺乏战略规划布局。

建国初期,国家将有限的资金用于研发两弹一星,以在总体上解决国家最紧迫的安全问题。
