波音研制超音速客机2小时从纽约飞到伦敦不是梦

网站介绍

  Earlier this year,a Norwegian Air flight said one of its crews set a record time for the fastest transatlantic flight by a subsonic passenger aircraft.
 
  本年早些时候,一架挪威航空公司的飞机说,其一名机组人员发明了次音速客机飞越大西洋的最快记载。
 
  The time:5 hours and 13 minutes,besting the previous record,which was three minutes longer.
 
  它用时5小时13分钟,比此前的记载快了3分钟。
 
  Not bad,but imagine boarding a plane in New York and arriving in London two hours later,about 1.5 hours faster than the time it took the legendary Concorde to complete the same journey on average.
波音研制超音速客机2小时从纽约飞到伦敦不是梦
  这很不错吧,但幻想一下,在纽约上飞机,两小时后抵达伦敦,比传奇的协和飞机完结相同旅程的均匀用时快了1.5个小时。
 
  This week,Boeing said it hopes to develop a passenger-carrying hypersonic airliner that would do exactly that,reaching speeds of Mach 5—about 3,800 mph,or roughly five times the speed of sound.
 
  本周,波音公司泄漏,它方案研制一种超音速客机,完结2小时从纽约到伦敦的飞翔,它的速度能到达5马赫——大约3800英里每小时或者说约是音速的5倍。
 
  Though still a preliminary design and without a name,Boeing said the aircraft could have military or civilian applications but won’t be in the sky for another 20 to 30 years.The company unveiled renderings of the proposed craft Tuesday at the annual American Institute of Aeronautics and Astronautics conference in Atlanta.
 
  波音公司表明,虽然这款飞机仍是初步设计,尚无姓名,可用于军事或民用,但在未来20到30年内不会呈现。周二,该公司在亚特兰大举办的美国航空航天研讨所年会上发布了这架方案中的飞机的效果图。
 
  “We’re excited about the potential to connect the world faster than ever before,”said Naveed Hussain,Boeing’s vice president of aeromechanics.“Although technology and regulatory challenges are ahead,Boeing has been studying hypersonics for over six decades,which makes us the right company to bring this technology to market when the world is ready.”
 
  波音公司航空力学副总裁韦德.侯赛因说:“咱们很快乐看到这种以空前的速度衔接国际的可能性。虽然未来还有技能和监管方面的应战,不过波音公司现已研讨超音速60余年,当全国际准备好时,咱们将是那个能让这项技能进入市场的公司。”
 
  Outside of the Concorde’s run between 1976 and 2003,supersonic travel has remained a largely elusive dream for commercial aviation,according to NBC News.
 
  据NBC报导,事实上,在1976年到2003年间,除了协和式飞机(一种中程超音速客机)在运转外,超音速游览仍然是商业航空中一个在很大程度上难以完结的愿望。
 
  If achieved—and if enough people are willing to pay for the pricey tickets—the rapid speeds could revolutionize world travel,experts say.
 
  专家表明,假如可以完结——且有足够多的人愿意为贵重的机票买单——那么高速度将会给国际游览带来革命性的改变。
 
  “It’s been a dream for a while now,”Stuart Craig,an assistant professor of aerospace and mechanical engineering at the University of Arizona,told NBC.“We’ve been striving for this hypersonic technology for the better part of half a century,but in recent years,advances in computational technology and materials technology have made it much more in grasp.”
 
  亚利桑那大学航空与机械工程助理教授斯图尔特.克雷格在承受NBC采访时说:“在半个世纪里,咱们一向在为更好地研制超音速技能而斗争。近年来,得益于计算机技能和资料技能的开展,咱们更好地把握了这项技能。”
 
  Supersonic air travel was a reality until 2003,when Concordes flying for British Airways and Air France were grounded,according to the BBC.
 
  英国航空公司和法国航空公司运用的中程超音速客机即协和式飞机在2003年中止运转,据BBC报导。
 
  British Airways said the plane was retired because of“commercial reasons,with passenger revenue falling steadily against a backdrop of rising maintenance costs for the aircraft,”the BBC reported.
 
  据BBC报导,英国航空公司表明,这架飞机退役的原因是“商业原因:客运收入继续下降,而飞机保护成本上升。”
 
  Seven years earlier,a Concorde made the trip between New York and London in two hours,52 minutes and 59 seconds,setting a record that remains,according to Reuters’news archives.
 
  依据路透社的音讯,7年前,协和式飞机曾以2小时52分59秒的速度完结纽约和伦敦之间的旅程,创下纪录并坚持至今。
