记者:这么大的影响,动荡,对你们而言,还能静心地潜心设计吗?
程不时:大家是很认真,认真到什么程度我举个例子,第一次涉及到噪声问题,大家都没接触过,这怎么办,就跟民航联系了,从这个最基层的调查起,而且说噪声的来源是什么,最大的来源是这个发动机喷口,这个喷口后面喷出来的喷流,有一个三角锥,这个里面噪声是最大的,那么这个噪声到底有多大,我这个隔音要隔多少,把它隔掉,没有数据,那么他们进去测,我们搞噪声的那些人就去测,怎么测呢?往里拿着拾音器,一个杆子伸到前面,伸到噪声锥里面去,还不够近,还要往里走。
记者:危险吗?
程不时:那是怕危险,怕震昏,把人要震昏,震昏就倒在那里头出不来了,所以你用绳子绑住,这是最土的方法,简直是过泸定桥的办法。
就是在这样艰苦的环境中,程不时他们完成了一项又一项的技术革新。
程不时:比如说油量的移动的问题,我们这个飞机要装56吨油,要装到机翼里面,但是飞机在空中,它要倾斜的,它一倾斜,油箱就在里面晃荡了,油就流了,怎么保证继续供油呢,有个实验,要做一个真正的,机翼一样大的油箱,我们真的做了这么一个油箱,很大的,几十吨油装进去,然后让它在空中可以这样动,几个动作怎么做呢?我们工人工程师,他设计的时候,用三个点把它支起来,这三个点不同的移动,就可以造成几个角度的变化,你知道吧,后来航空部的副部长,搞技术的副部长,他一看这是开创性的,都没看见过的,他就是利用这个原理,利用创造性思维,他解决了这个问题,这个我后来到了美国,美国有个造大飞机的公司,我去看,他们做了一个实验,我看他们做,他们怎么做,机翼上吊很多钢索,然后这边拉那边拉,可以让它在空中变成各种形状,那比我们土多了。
