原标题:中国长三甲系列运载火箭实现100次发射

中新网四川西昌4月20日电(郭超凯)北京时间4月20日22时41分,中国自主研制的长征三号乙运载火箭在西昌卫星发射中心点火起飞,成功将北斗三号系统首颗倾斜地球同步轨道卫星送入太空。中国长征三号甲系列运载火箭(以下简称长三甲系列火箭)的发射次数正式刷新为100次,截至目前,这是长征系列运载火箭家族中唯一达到百次发射的单一系列火箭。

据介绍,长三甲系列火箭由长征三号甲、长征三号乙、长征三号丙三种低温液体运载火箭组成。该系列运载火箭包揽了目前中国绝大多数高轨道航天器发射任务,是长征系列运载火箭高强密度发射的“主力”,不仅是中国目前高轨道上发射次数最多、成功率最高的火箭系列,同时也多次承担了商业卫星的发射任务,被誉为中国的“金牌火箭”。

“长三甲系列火箭100次发射的成功率为98%,这是和世界任何一个火箭型号发射成功率相比都名列前茅的成绩。”中国航天科技集团一院长三甲系列火箭总指挥岑拯说。

自1994年2月8日,长征三号甲火箭圆满完成首飞任务以来,长三甲系列火箭型号已经走过了辉煌的25年,在探月工程、北斗工程和国际商业发射服务中发挥了重要作用。

中国航天科技集团一院长三甲系列火箭总设计师、中国科学院院士姜杰在接受中新社记者采访时表示,在长三甲系列火箭100次发射中,有36次执行北斗工程发射任务,成功将44颗北斗导航卫星、4颗北斗导航试验卫星送入轨道(其中12次是“一箭双星”);有5次执行探月工程,成功将嫦娥一号、嫦娥二号、嫦娥三号、嫦娥四号、嫦娥五号载入返回飞行试验器送入地月转移轨道;有36次执行通信卫星工程,发射36颗通信卫星;有7次执行气象卫星工程,发射7颗风云气象卫星;有16次执行国际发射任务,发射16颗国际商业卫星。
