徐立平,中国航天科技集团公司第四研究院7416厂高级技师。自1987年入厂以来,徐立平一直为导弹固体燃料发动机的火药进行微整形。在火药上动刀,稍有不慎蹭出火花,就可能引起燃烧爆炸。目前,“火药整形”在全世界都是一个难题,无法完全用机器代替。下刀的力道,完全要靠工人自己判断,药面精度是否合格,直接决定导弹的精准射程,0.5毫米是固体发动机药面精度允许的最大误差,而经徐立平之手 Xu Liping, China Aerospace Science and Technology Corporation Fourth Institute 7416 Factory senior technician. Since entering the factory in 1987, Xu Liping has been micro-plastic gunpowder for missile solid fuel engines. In the gunpowder, a slight accidentally rub the spark, it may cause a burning explosion. At present, “gunpowder shaping” is a problem all over the world and can not be completely replaced by a machine. Under the knife force, completely depends on the workers themselves to determine whether the accuracy of the drug face, the missile directly determines the precise range, 0.5 mm is the maximum allowable accuracy of solid engine drug face, and by Xu Liping hand
