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

今天,中国航空发动机要拿出当年“两弹一星”的精神,集中力量对有决定性影响的核心技术进行攻坚,实现技术突破。

要知道,核心技术突破的意义不仅限于航空发动机本身,更在于核心技术的拓展和延伸。

举个例子,凭借空军投资以及GE9技术验证机和GE13核心机,美国通用电器公司研发出了F101发动机,应用于B-1“轻骑兵”轰炸机。

随后,以F101核心机为基础,通用电气发展出了F110和F118两款涡扇发动机。前者应用于F-14B/D、F-16C/D、日本F-2等多型战机,并成为普·惠F100的竞争对手;后者则成为美空军B-2隐形轰炸机的航空动力。

接着,通用电气公司又向商业领域拓展,大胆拿出F101核心机技术与法国合作,开发出CFM56高涵道比涡扇发动机,应用于A320系列,A340、B737、DC-8-70系列等大型商用客机,累计制造30000台,创造了非常可观的商业价值。

搭载CFM56发动机的波音737-800客机

不仅如此,通用电气又以J79为基础,改进发展出LM2500型和LM6000型船用燃气轮机,广泛应用于各类军舰、航空母舰、军用两栖舰船、以及游轮和多种商用运输船,具有极其丰富的潜在应用价值。

美国阿利伯克级导弹驱逐舰的LM2500燃气轮机就是从J79核心机发展而来

不过,航空发动机是当今世界上最复杂、多学科集成的工程机械系统,它的发展不可能一蹴而就。

国产发动机成熟,歼20换发,只是中国航空工业追赶世界最先进水平的一个开始。

未来,会有更多飞机搭载更强大的“中国心”一飞冲天。
