四、關(guān)于航空火箭的作文?
托舉著“神舟”五號載人飛船的“長征”二號F型運載火箭在轟鳴聲中直沖藍(lán)天,把一條巨龍般的橘紅色烈焰留在秋日的戈壁長空。
乳白色的“長征”二號F型火箭起飛重量479。8噸。它是在“長征”二號E型火箭基礎(chǔ)上研制的以發(fā)射飛船為主要任務(wù)的運載火箭,1992年開始研制,1999年首發(fā)成功。此前,這種火箭已經(jīng)成功地將4艘無人飛船送入太空。
作為中國火箭家族中最重、最長的成員,“長征”二號F型火箭采用了55項新技術(shù),使它同時成為中國航天史上技術(shù)最復(fù)雜、可靠性安全性指標(biāo)最高的火箭。
這枚火箭首次采用了垂直總裝、垂直測試和船、箭、塔組合體垂直運輸?shù)摹叭埂睖y試發(fā)射模式,改變了過去水平總裝、水平運輸?shù)哪J?;首次采用遠(yuǎn)距離測試發(fā)射控制技術(shù),其中先進(jìn)的光電技術(shù)、自動控制技術(shù)和弱信號的遠(yuǎn)距離傳輸技術(shù)均達(dá)到國際先進(jìn)水平。
為了進(jìn)一步增大飛行中的安全性,它配置有專門的故障檢測處理系統(tǒng)和逃逸系統(tǒng)?;鸺诖l(fā)段和上升段發(fā)生故障時,能夠自檢測、自診斷,發(fā)出故障信息給逃逸系統(tǒng),逃逸系統(tǒng)隨即帶飛船離開箭體,從而保障航天員的安全。
“長征”二號F型火箭還首次研制了全冗余的控制系統(tǒng),實現(xiàn)雙套制導(dǎo)與穩(wěn)定控制技術(shù),其中雙CPU計算機、三余度伺服機構(gòu)和雙回路穩(wěn)定平臺技術(shù)均達(dá)到國際先進(jìn)水平。從發(fā)射“神舟”三號開始全面覆蓋系統(tǒng)的冗余控制大大提高了運載火箭的可靠性,為實現(xiàn)載人奠定了基礎(chǔ)。
為保證火箭高可靠性和高安全性,火箭電器系統(tǒng)就有近4萬個元器件。所有元器件都經(jīng)過了篩選和40多個回合的增長試驗,不僅要在模擬飛行環(huán)境下達(dá)到設(shè)計指標(biāo),而且在此基礎(chǔ)上要有裕度。比如,從火箭發(fā)射到飛船入軌只有短短的600秒,但火箭的可靠性增長試驗卻達(dá)到了546小時。這樣,就使“長征”二號F型火箭的可靠性指標(biāo)達(dá)到0。97,這就是說發(fā)射100發(fā)火箭只能有3次出現(xiàn)問題。同時,火箭的安全性指標(biāo)達(dá)到0。997,意味著1000次故障所采取的救助措施只有3次是不成功的。
總之,長二F型火箭是我國設(shè)計制造的世界最先進(jìn)的運載火箭之一。
