让“中国之翼”翱翔天际

2017-08-10 05:32:29   中国青年网

经过首架机历练,装配一线积累了不少经验,但困难还是时不时“光临”。第二架C919飞机内外襟翼中间有安装电气设备的小舱,由于处在机翼后缘两块活动面中间,空间狭小,对它的结构加强成了装配中的又一难题。党员骨干雒学峰带领技术骨干从狭窄油箱钻进去操作,队员们笑称:“进去练瑜伽,出来洗桑拿。”

相邻的厂房内,第三架C919飞机生产正在进行。不同于前几架机,103架机前、中机身对接框制孔完成快速轻松,这得益于新技术的应用。机身对接班组党员班组长傅伟说,103架机首次实现柔性轨道制孔。前、中机身对接框制孔难点在确定孔位。按照以往做法,4名工人需花费一整天时间,先在对接框上打定位孔,再根据定位孔位置画线确定其余孔位。使用自动柔性轨道制孔设备后,只需将三维数模导入系统,设置定位孔位置,机器便可自行完成,全部工作3小时内即可完成,质量稳定性也优于人工。

年轻队伍挑起复材机翼制造大梁

复材制造技术是撬动先进民机制造发展的一个支点。复材机翼作为中国商飞公司重点任务之一,瞄准未来民用客机制造需求,自启动以来就备受关注。一支平均年龄不到30岁的队伍挑起了复材机翼制造的大梁。

为保证复材梁零件外形精度,机翼项目需引入牺牲层外形控制技术,该技术在公司技术储备中尚无经验可循。党员骨干魏冉、张联合、龚佑宏和技术骨干赵科新组成攻关小组,发挥各自的专业优势,迅速定位难点,在短时间内攻克。

复材机翼装配要进行多项技术检测,气密试验是重要一环。内外襟翼间有小舱,以往让个头小的技术工人从油箱钻进去,内部有问题只能根据工人的描述进行处理。能不能运用科技手段优化?微信群讨论中,有人提议在舱内安装摄像头,正负责AR虚拟现实系统的青年党员庞微建议把AR眼镜带过来试一试。果然,工人戴上AR眼镜进入油箱作业,其他技术人员就能通过平板电脑同步观看,“实时展示法”为气密试验成功立下了“汗马功劳”。

就是这样一群党员,他们用赤诚忠心传递梦想力量,用雷厉行动筑起钢铁长城。哪里有难关,哪里就有冲锋在前的党员,哪里有需要,哪里就有高高飘扬的党员攻关队旗。
