国之“神器”:来自C919和“天舟一号”的对话

2017-04-22 10:26:52   新华网

C919:锻造经济转型升级的“黄金龙骨”

天舟一号:拥抱“太空经济时代”的到来

在上海飞机设计研究院的工程师张建军等专家眼里,C919大型客机是不折不扣的“中国制造”。

C919整机产权属中方所有,研制的核心团队属于中国商飞公司,从设计、总装、试飞到销售等关键环节都掌握在中方手里,形成“中国设计、系统集成、全球招标,逐步提升国产化”的发展思路。

张建军认为,波音和空客也并非由一家一国独立制造完成。尽管C919不是100%纯国产,目前使用国外发动机,但预计3年后可换装国产长江1000A发动机。中方不仅独立完成C919机身与气动布局的设计与制造,在液压系统、起落架、辅助动力、电源系统等方面也深度参与,正在逐步吃透核心技术。

C919大型客机具有无可替代的开创性、奠基性和战略性,为我国持续发展不同种类、不同层级、不同用途的干线飞机打下基础,从而最终形成有国际竞争力的“国字号喷气客机家族”,使大飞机成为彰显中国装备制造实力的新名片。

专家认为,C919的研发,不但显著改善了我国民用航空工业发展的基础面貌,同时为我国经济转型升级在锻造着一根蕴藏巨大潜力的“黄金龙骨”。 H  伴随着C919大型客机项目的推进和我国喷气客机进入批产,我国民用航空产业链必将逐步发挥出巨大的经济潜力。商用大飞机产业将拉动航空发动机、高精数控、航电设备、冶金、新材料等上下游产业发展,创造万亿美元的产业链。

“天舟一号飞行任务作为空间实验室任务的收官之战、载人空间站工程的关键一战,是我国载人航天工程稳中求进的重要一步。”中国航天科技集团公司五院院长张洪太说。

“大型空间站建成后,我国载人航天事业会更加开放,有望产出一大批重大科学成果,突破一大批核心关键技术,获得无法估量的经济和社会效益。”

服务社会、造福人类,这正是中国建设空间站的目标和动力。天舟一号的成功发射为我国经济的持续高速增长、科技的快速发展、高端人才培养和综合国力的提升都有着巨大的意义。

空间科学研究的应用前景亦十分广阔。利用空间站开展空间生物学研究,可以为培育优良物种、探索疾病机理、研发生物药物、改进人类健康服务;开展微重力流体与燃烧研究,可以促进新型清洁能源开发、改善地球环境。
