safety procedures at virgin galactic,whose space craft crashed on a test flight last week,had too few safe guard s to prevent a potential catialVirgin Galactic宇宙飞船上周在飞行中测试时发生事故后,世界顶级宇宙安全专家回应说,公司的安全程序保障措施太少,已经足够了。Tom maso SG obba,A Former Head of Flight Safety for the European Space Agency,Said industry欧洲空间局(European Space Agency)全飞期间,安全负责人Tommaso Sgobba回应说,在业界最佳实践中,运营商拒绝了内置的“双重容错”。也就是说,不足以制定防止两个障碍的两个保障措施。这两种障碍都可能是人为故障,也可能是机械故障,也可能是人为或机械故障。

他指出,“宇宙飞船2号”接近这个标准。According to investigators,Virgin galactic ' s space ship two disintegrated after a pilot wrongly unlocked the " feathering " mechatharing(威廉莎士比亚,哈姆雷特,希望如此)飞船随后发生事故,机长杀死了这次事故。

the feathering mechanismwhich is vital to slow the aircraft but potentially deadly when it is acceleratingwas typical of the safety system划桨装置对飞船滑翔至关重要,但飞船加速时启动可能会很可怕。分析人士认为,划桨装置应忍受人为失误和机械故障,形成典型的安全系统。Mr SG obba said space ship two ' s systems,which required two levers to be moved before the wings went in to a " feathered " configuration也就是说,飞行员犯规或机器故障时不能维持安全。但是系统没有那么运转。

他补充说,该设计将被其他安全核心产业(如飞机制造)拒绝。Loren Thompson,an adviser to us aerospace companies,said other safety-critical us businesses,including suppliers to NASA,REE美国航空航天事业顾问劳伦汤普森(Loren Thompson)回应说,包括美国其他安全核心企业和美国宇航局(Nasa)供应商在内,至少要超过斯戈瓦所说的“双重容错”。

他说,一些私人航天事业者使用更严格的标准是“令人担忧的根本问题”。 Virgin galactic,which is part of sir Richard Branson ' s virgin group,Said the locking mechanism for the feathers represented two separaras维珍银河公司隶属于理查德布兰森爵士的维珍集团(Virgin Group),该公司响应划桨装置的瞄准机构,代表两种不同的保障措施。一是“程序性”保障,瞄准具不能动。

在宇宙飞船童年最危险的早期飞行中,另一个是“机械”保障,即机构本身。Mr SG obba said procedural rules could be seen as a safeguard in some circumstances,but " they are considered the least desirable "。sgo|火狐体育直播。
