    宇航推進:國內第一家研發液氧甲烷發動機的公司要進軍產業上游

    2019-07-02 03:37:16 創業邦2019年5期

    侯長海

    宇航推進CEO 王明哲 宇航推進是目前國內唯一一家做全品類的火箭發動機的公司

    在2014年11月,國務院發布《國務院關于創新重點領域投融資機制鼓勵社會投資的指導意見》,首次提出“鼓勵民間資本參與國家民用空間基礎設施建設”。隨后,國內商業航天興起,一批商業火箭、衛星初創公司破土而出。

    而在商業航天產業鏈上游,國內動力系統卻面臨缺乏。一方面,來自長城工業集團《商業火箭發展應對策略研究分析》的數據顯示,我國“十三五”宇航型號國家任務發動機缺口仍近40%;另一方面,來自聯合發射聯盟(ULA)的數據顯示:一級火箭發動機占運載火箭全箭總成本超過50%,二級火箭發動機占全箭總成本近40%。

    成立于2018年8月的宇航推進是國內為數不多的幾家商業航天動力領域的公司之一,也是第一家研發液氧甲烷發動機的公司,與美國space X 的火箭發動機技術路線相同。其希望通過流程簡化、工藝設計改良等方式,為商業火箭、衛星等設備提供低成本、高可靠的發動機和動力系統解決方案。

    國內首家全品種火箭發動機

    目前,在國內商業航天領域大部分公司大多集中在商業火箭,其次是商業衛星,已公開的專業火箭發動機公司只有三家,分別是靈動飛天、慣性飛越和宇航推進。

    宇航推進CEO王明哲告訴創業邦(微信搜索:ichuangyebang),宇航推進是目前國內唯一一家做全品類的火箭發動機的公司,主要產品包括一級/二級/三級液氧甲烷發動機、姿軌控發動機以及其他非標型技術成果轉化等。其中,宇航推進率先研發的的是“滄龍”系列液氧甲烷發動機。

    目前,商業航天市場的火箭發動機主要分為固體火箭發動機和液體火箭發動機兩種。其中固體火箭發動機的特點是生產流程快、便于儲存,但推力小、成本高;而液體火箭發動機成本低、推力大,但研發流程冗長、不易儲存。美國的商業航天市場以液體火箭發動機為主流,而國內商業航天剛起步,商業火箭公司為在市場搶得先機,大多選擇自研或購買固體火箭發動機。

    王明哲表示,雖然現階段火箭公司大多選擇固體火箭發動機進行發射,但后續液體發動機將是必然選擇,主要原因是固體發動機的高成本在商業航天領域競爭力很低。在液體火箭發動機的路線上,宇航推進選擇的是液氧甲烷液體火箭發動機。王明哲表示,和液氧煤油等其他路線相比,液氧甲烷具有不結焦、成本低、易維護、無污染、來源豐富的特點,一公斤只需要幾塊錢,而且常溫條件下會迅速汽化,不會污染環境。

    “Space X的第一代發動機用的是液氧煤油,而且已經研發到極致,但是第二代發動機就換成了液氧甲烷,原因就是這幾個特點,更適合商業航天。”王明哲說。

    產品進度方面,宇航推進首批液氧甲烷發動機的研發設計工作已經完成,目前處于內測階段。預計2019年3月底,完成試驗廠房基建工程,5月完成綜合液流試驗臺設備安裝,明年6月首批產品將會正式投入市場。

    體制內追性能?體制外講成本

    王明哲告訴創業邦(微信搜索:ichuangyebang),目前國內尚沒有能夠用于商業航天的液體火箭發動機。原因是液體火箭發動機的研發周期較長,并需要相對較高的成本投入。

    軍用航天和商業航天是兩個概念。國家級的航天項目,大多是軍事、或是技術研發用途,其中的產品工藝無法直接復制到商業領域,比如長征三號運載火箭,成本高達3億人民幣,基本不適用于商業用途。

    關于成本控制,王明哲表示宇航推進會采用產品化思路,不會盲目追求性能,而是聚焦在低成本和可靠性上。產品研發上,不設計過多品種,只生產10噸和60噸運力的發動機,比如20噸、120噸的運力可通過組合來完成;同時,宇航推進研發一級和二級的火箭發動機時采用通用配件,降低整體成本;設計方案出來后,在每一個研發環節配備工藝人員,對生產工藝、成本控制上嚴格把關,盡可能簡化流程。宇航推進還自主研發了一套健康監測系統,用于實時監測火箭發動機的運行狀態。

    據了解,宇航推進將于近日開始燃氣發生器點火試驗。燃氣發生器是泵壓式液體火箭發動機中的關鍵部件,用于產生高溫高壓燃氣,驅動渦輪泵對推進劑進行增壓,增壓后的推進劑進入燃燒室燃燒,經噴管噴出,推動火箭升空。開展燃氣發生器點火試驗,意味著火箭發動機研制工作已進入最后測試階段。

    核心團隊方面,王明哲本人曾就職于航天科技集團六院、五院、一院總體部,從事航天型號研制超十年,帶領團隊參與我國液體火箭發動機、衛星、火箭等多個型號總體研制,一院長征獎獎章獲得者;?總經理郭利明曾就職于航天科技集團六院,從事空間飛行器軌姿控發動機研制和總體研制工作超十年,任工程組長和課題技術負責人;?副總經理李文鵬曾就職于航天科技集團第六研究院,從事液體火箭發動機生產試驗管理工作超十年,帶領團隊開展我國多個低溫液體火箭發動機研制管理工作,擁有廣泛的火箭發動機生產、試驗資源。

    宇航推進此前已完成由哈工大機器人集團領投的1000萬人民幣天使融資,目前正在進行Pre-A輪融資。
