印度一枚搭载通讯卫星的运载火箭25日发射后不久失控并偏离航向。依照地面控制人员指令，火箭在空中“自爆”。一些航天技术人员说，这次发射失败是印度空间研究组织遭遇的“巨大挫折”。<br /> <br /> 这枚火箭为同步卫星运载火箭（GSLV）F06型，当地时间下午4时4分在位于印度东南部斯里赫里戈达岛的萨蒂什·达万航天中心点火升空，原定飞行19分钟后将卫星送入预定轨道。<br /> <br /> 印度空间研究组织主席K·拉达克里希南说，火箭“发射45秒后失去控制”，地面控制人员向第一级发动机发出指令，但火箭未按指令工作。<br /> <br /> 按照他的说法，火箭第一级在发射后50秒内表现正常，随后出现故障。发射后63秒，地面控制人员发出自毁指令，火箭在空中爆炸。监测系统显示，火箭残骸坠入孟加拉湾。<br /> <br /> 空间研究组织设立的故障分析委员会初步认定，发射失败与4台捆绑式液态燃料发动机相关。火箭发射0.2秒后，1台发动机失灵，仅3台正常工作，致使火箭飞行控制能力大幅降低。<br /> <br /> 发射后大约50秒，火箭飞行速度达到音速，但推力不足导致高度误差较大，气动载荷超过设计极限，因而无法正常飞行。<br /> <br /> 委员会认为，这可能是生产过程中疏忽所致，检查和验收试验等工序未发现这一安全隐患。<br /> <br /> 这是印度同步卫星运载火箭连续第二次发射失败。今年4月15日，印度首枚装配国产低温发动机的D3型同步卫星运载火箭点火8分钟后失控，原因是低温发动机未能成功点火。<br /> <br /> 印度国防问题分析研究所研究员阿贾伊·莱勒对卫星发射项目仍充满信心。他说，技术人员不久将重新发射一颗卫星。<br /> <br /> 印度近年加大太空探索力度，去年8月完成首次无人探月任务，计划2016年发射首个载人航天器。 </td></tr></table> </div> <div id="comment_716002" class="cm"> </div> <div
