一门3兄弟皆为航天院士 2人曾在国防科大任教

2017-04-25 09:05:39   国防科大

他自学计算机语言,利用当时学院计算机系刚刚研制完成的441B-Ⅲ晶体管电子计算机,运用他刚研究出来的液体火箭发动机燃烧模型,对某型号发动机的燃烧过程进行数值模拟计算,与实际型号的试车结果非常接近。据此撰写的论文《自燃推进剂火箭发动机燃烧室设计简化模型》在1978年10月中国工程热物理学会成立大会暨第一次学术会议上宣读,同时发表了所有计算源程序。

这是国内应用燃烧模型在计算机上对实际液体火箭发动机燃烧过程进行数值模拟计算的第一篇论文,受到研制单位和学术界的高度重视。

在钱学森鼓励下研究发动机燃烧

1978年6月,长沙工学院更名为国防科学技术大学,学校组建了燃烧理论和热学教研室,庄逢辰被任命为室主任。为了提高国内燃烧理论研究的水平,他组织研究团队建设了研究性实验室,美国、英国和俄罗斯的燃烧理论和液体火箭发动机专家都前来参观。他还翻译了当时美国刚出版的作为大学生教材的《燃烧导论》一书,此书于1981年出版,受到全国同行们的极大欢迎。

1981年,钱学森第二次到国防科大指导工作,给学校提出了17项国防前沿迫切需要研究的课题,其中第一项就是液体火箭发动机燃烧。

会后庄逢辰得幸向钱学森请教问题。

钱学森对他说:“不同的推进剂燃烧性能不一样,你能否算一算?液体火箭发动机燃烧不稳定性也需要进一步研究,现在还没有掌握其规律。”

当时庄逢辰对钱学森说,“我大学学的是机械工程,后来调到动力机械系工作搞锅炉燃烧,现在又搞航天,是否行转得太多了。”

“学锅炉好啊!我大学学的是火车头,也是锅炉呢!”钱学森笑着说,“锅炉和液体火箭发动机只是研究的工程对象不一样,但很多基础理论是相通的。你不单可以研究液体火箭发动机燃烧,火箭导弹中的很多问题你都能够研究。”

这些话给了庄逢辰极大的鼓舞。

1983年,他邀请美国著名燃烧理论专家F.A.Williams来校讲学,举办了为期一个月的学习班。

1990年他将F.A.Williams1985年在美国正式出版的《燃烧理论-化学反应流动系统的基础理论》一书翻译成中文,并作为研究生教材,国外大学亦普遍应用此书作为研究生教材,被称为“天书”。
