    90后小伙成火箭專家!網友:這才應該是熱搜第一!

    發布時間:2019-07-31 來源:文明亳州

    今天,有一個叫做#90后小伙成火箭專家#的話題,在微博上引起了一些網友的討論,有的網友甚至留言說:這才應該熱搜第一啊!

    blob.png

    這個90后小伙,叫于新辰。

    于新辰畢業于清華大學工程力學與航天航空工程專業,畢業后來到大涼山深處的西昌發射場工作,參加并圓滿完成了包括“嫦娥三號”“嫦娥五號再入返回飛行試驗”“風云四號”“北斗三號”等重大任務在內的共計60次、80多顆衛星的航天發射任務,為我國航天事業作出了突出貢獻。

    他說:“閑下來的時候也想家,但是為了這份事業,我愿意堅守下去。”

    今年3月10日0點28分,在西昌衛星發射中心,我國長征系列運載火箭完成了第300次發射,將“中星6C”通信衛星送入太空進入預定軌道。3天后,《新聞聯播》播出了西昌衛星發射中心在衛星發射成功后,現場人員共同唱響“我和我的祖國”,向祖國表白的畫面。其中,就有于新辰的身影。

    于新辰,現任西昌衛星發射中心工程師、西昌發射場低溫動力系統指揮員。2011年清華大學畢業后,他懷著攜筆從戎、航天報國的志向來到大涼山深處的西昌發射場,在山溝里一待就是8年。

    立志航天事業

    ▲于新辰畢業照

    2011年,于新辰面臨畢業分配時,他認為在清華學習了四年的航天航空知識,祖國又處在由航天大國向航天強國邁進的重要階段,應該把所學所獲貢獻給我國的航天事業。“我就放棄了讀研的機會,直接來到大涼山深處的西昌發射場一線。”

    ▲于新辰接受媒體采訪

    于新辰在發射場的第一個崗位是電梯操作員,每天上班就是在電梯里接送上下塔架的人員到相應的樓層,工作簡單且枯燥,但他仍履行好自己的職責。2012年5月他被安排到火箭常規動力系統,成為一名普通的崗位操作手。“雖然只是做一些技術操作方面的活,跟理論專業相關性不大,但掌握這些基本操作是很有必要的,有利于以后成為指揮員時把握技術狀態。”于新辰笑著說。

    ▲認真工作中的于新辰

    通過一年時間的學習和工作,他完全勝任了該崗位,并擔任該系統箭上專業負責人。由于西昌發射場高密度任務的需求,他又再次被分配到火箭低溫動力系統擔任操作手。低溫動力系統涉及液氫液氧低溫推進劑的加注工作,低溫推進劑溫度極低且易燃易爆,測試流程復雜繁瑣,發射之前要連續精神高度集中、高強度工作8個小時以上,他在這個系統一待就是6年。

    ▲受到習近平總書記親切接見

    作為優秀科技人員代表,2018年新春之際,27歲的于新辰受到習近平總書記親切接見。“首長微笑著點頭說,年輕人已經擔任了骨干,很好。希望以后繼續努力。”于新辰回憶說,習主席的話很溫暖,讓他備受鼓舞。

    苦練真功夫

    液氫液氧低溫推進劑號稱“一粒米從一米高處掉落的能量就會引起爆炸”,稍有泄漏會造成難以預測的后果。因此,發射場對火箭的氣密性要求非常高。為練好氣密性檢查基本功,于新辰經常對照圖紙反復核對每一個接頭狀態,以至于后來閉著眼睛都能說出接頭的位置和細節,被同事們稱為“活圖紙”。

    另一方面,為了能快速發現可能存在的漏點,他在氣檢過程中常常仔細辨聽聲音,練就了“聽聲檢漏”的本領。

    ▲于新辰察看設備運轉情況

    2015年至今,于新辰已經17次擔任低溫動力系統指揮員,他對狀態的把控更加嚴格,先后組織排除加注管路漏氣、供氣壓力異常、排氣管路存在多余物等20余次典型故障和隱患。

    2018年8月25日凌晨,在指揮席已經通宵連續工作了8小時的于新辰突然發現傳感器顯示火箭三級發動機的關鍵元器件出口壓力值比指標要求偏高,而且持續升高。這個元器件直接影響三級發動機的正常啟動和關機,如果故障不能在1小時內排除,那么這次任務極有可能會終止,原定的兩顆北斗三號衛星的發射時間至少推遲7天以上,如果冒著風險發射,則極可能造成三級火箭不能工作,衛星無法入軌。

    ▲于新辰(中)在火箭發射前緊急處置故障

    十萬火急的情況下,技術人員圍在一起討論排故方案。嘗試第一個方案以后情況沒有好轉,嘗試第二個方案后壓力值繼續升高接近安全值上限,情況進一步惡化!這時還有5分鐘就到允許排故時間的后限,時間一分一秒地過去,指揮大廳寂靜一片。這時于新辰依據元器件的工程特性,認為提高元器件的入口氣體壓力,其出口氣體壓力應該會降低,他沉穩果斷地下達了提高入口氣體壓力的口令,這個參數在1分鐘內迅速下降至指標要求范圍內。就這樣,在距離允許排故時間后限只剩兩分鐘的情況下,于新辰成功指揮系統人員排除了這個關系任務成敗的故障,為任務的成功作出了突出貢獻。

    ▲清華大學校友與于新辰交流(沈志杰 攝)

    2018年,中國全年航天發射次數首次超過美國,位列世界第一。其中西昌發射場全年完成17次航天發射任務,超過往年發射記錄近一倍。中國奇跡的創造,源于無數像于新辰這樣的航天人的默默堅守和付出。

    希望成為“01指揮”

    由于工作繁忙,再加上交通不便利,于新辰一般每年回家一次。“去年爸媽來看我,住了一個星期。”說起這件事,作為家中獨子的于新辰很是開心。

    ▲于新辰回老家渦陽“傳經”

    為了不讓父母擔心,于新辰沒有完全透露自己的工作環境。除了地處偏遠,在低溫動力系統工作還是有一定危險性的,但對此于新辰顯得十分從容,“只要嚴格按照規程和要求去測試和操作,實際上是不會有什么嚴重后果的。此外,我們也是有相關預案的。”

    ▲于新辰(中)參加電視節目向全國觀眾普及航天知識

    于新辰在工作之余喜歡看書和跑步,但更多的時間還是花在了本職工作上。“可能跟性格有關吧,我不喜歡出去玩,平時經常在辦公室加班,想把工作干得更細一些。”于新辰說。

    ▲于新辰業余時間拼接航天模型

    作為西昌衛星發射中心最年輕的分系統指揮,對于未來他也有自己的“小目標”。每個在發射場系統里的人,都希望有機會能成為“01指揮”。對此,于新辰也不例外。“‘01’相當于發射場的指揮中樞,是指揮中心的大管家,能擔任這個崗位,一方面是能力的肯定,另一方面,也是一份榮譽。”于新辰說。

    ▲于新辰生活照

    面對西昌發射場的“扎根樹”,于新辰寫下:“繁星閃爍著/深藍的太空/那棵用信仰澆灌的樹/為我指明了逐夢九天的路……”

    航天事業是“萬人扛一桿槍”

    “心有所定,志有所立,事有所成。”

    行勝于言,是航天人最嘹亮的號角

    托舉嫦娥,助飛北斗

    一心想著做好崗位工作

    于新辰的航天夢想

    正在點滴落地生花
