登顶“玉龙” 航空报社发文记直-10发动机研制团队

2017-06-08 15:42:40   中国航空报

“玉龙”发动机几乎是白手起家、从头做起。“无论身处何种条件,从没有人产生放弃的念头。没有条件就创造条件,不等不靠。我们坚持下来了,总算把发动机干出来了。”

参研人员已经记不清曾经多少次陷入技术难关无法突破的困境。副总师黎亮回忆起那段欢乐与汗水交织的岁月时说:“当年所里不具备大型运算的条件。为完成发动机数据计算工作,只好经常往返于长沙计算所和研究所两地之间。当第一台核心机设计工作宣告完成的那一刻,大家笑啊跳啊,高兴得说不出话。”

如果说试验是艰苦的,那么试飞更像是一场毅力的考验。在跟飞人员的作息时间表上没有双休日。只要有飞行任务,跟飞人员就得守候在现场,随时处于待命状态。有时为了排故,通宵奋战在现场。2007年,发动机试验发生涡轮叶片榫头裂纹现象,当时要求跟飞人员每5个飞行小时从发动机尾喷管用孔探仪对发动机涡轮叶片进行检查,连续两个多月工作没有间断。

要考核发动机的安全性、可靠性以及各种技术性能,就必须在高温、高寒等多种气象环境下,进行极限条件试验。夏季飞行的最好时间也是一天当中气温最高的时间。在发动机地面试验过程中,跟飞人员坐在一辆旧公交车改造成的测试车里。车内温度高达50摄氏度,跟飞人员好像刚从水里捞出来一样。发动机停止工作后,跟飞人员还要爬上飞机检查各个部件,完全不顾烈日炙烤。发动机高寒试飞主要在内蒙古进行,正遇上百年不遇的冰冻天气。试验现场没有专业的飞机暖库,试验都在零下三四十摄氏度的户外进行。在极端寒冷的条件下,跟飞人员连续20多天坚守试验现场,圆满完成高寒试飞科目。

经过艰苦卓绝的努力,“玉龙”发动机研制团队攻克了一系列关键技术难题,打破了国外严密的技术封锁,自主自立走完了型号研制全过程,在我国闯出了一条独立自主研发先进涡轴发动机的道路,在国内首次自主建立、应用并验证先进涡轴发动机研发体系。

“玉龙”发动机工程获国家科技进步一等奖

执著坚守忠诚不辱使命

执著坚守,体现了航发人忠诚使命、动力强军、科技报国的坚定信念和负重前行、奋力攻坚、百折不挠的拼搏精神。

放弃只是一瞬间,坚持却是一辈子。无论面临多大的艰难困阻,“玉龙”发动机研制团队坚持国家利益至上,始终站在捍卫国家和民族尊严的高度,不计名利得失,克服了常人难以想象的困难,承受着常人难以承受的压力,步履坚定地走完型号研制的全过程。
