中國航天科技集團(tuán)有限公司介紹,新一代運(yùn)載火箭長征十二號已完成各項(xiàng)研制工作,正在開展首飛箭的總裝總測,計劃2024年在海南文昌商業(yè)發(fā)射場,完成首飛箭的發(fā)射任務(wù)。
The research and development stage of the Long March 12, the latest model in the Long March family, has been completed, according to the China Aerospace Science and Technology Corporation (CASC). Assembly and testing of the first Long March 12 rocket is underway, and the maiden flight has been scheduled to take place this year at the Hainan International Commercial Aerospace Launch Center in Wenchang, Hainan province.
【知識點(diǎn)】
長征十二號運(yùn)載火箭是我國首型3.8米直徑單芯級液體運(yùn)載火箭,兩級構(gòu)型,一級采用四臺推力1250千牛的液氧/煤油發(fā)動機(jī),二級采用兩臺推力180千牛的液氧/煤油發(fā)動機(jī)。近地軌道運(yùn)載能力不小于10噸、700公里太陽同步軌道運(yùn)載能力不小于6噸。整流罩標(biāo)配5.2米和4.2米直徑,可根據(jù)不同任務(wù)進(jìn)行多尺寸適配。
長征十二號運(yùn)載火箭繼承現(xiàn)役長征系列火箭高效的單芯級串聯(lián)構(gòu)型,簡單、可靠、任務(wù)通用性好,提高了太陽同步軌道入軌能力和低軌多星座組網(wǎng)能力,進(jìn)一步完善和拓寬了我國新一代運(yùn)載火箭的型譜,助力我國航天運(yùn)輸體系的高質(zhì)量發(fā)展,將單芯級液體火箭運(yùn)載能力和大整流罩包絡(luò)提升了一個新臺階。
