📖 逐句对照翻译
An experimental aircraft developed by a private American company broke the sound barrier during a recent flight test.
一家美国私营公司研发的实验性飞机在最近的一次飞行测试中突破了音障。
California-based company Boom Supersonic built the plane, named XB-1.
总部位于加利福尼亚州的Boom Supersonic公司建造了这架名为XB-1的飞机。
The company said the aircraft reached a speed of Mach 1.05 during a test on January 28.
该公司表示，这架飞机在1月28日的一次测试中达到了1.05马赫的速度。
The test flight operated from the Mojave Air & Space Port in Mojave, California.
这次试飞是从加利福尼亚州莫哈韦的莫哈韦航空航天港进行的。
Any speed greater than Mach 1.0 breaks the sound barrier and is considered supersonic.
任何超过1.0马赫的速度都会突破音障，被视为超音速。
The American space agency NASA explains that at sea level, the speed of sound is estimated to be about 1,236 kilometers per hour.
美国国家航空航天局（NASA）解释说，在海平面上，音速估计约为每小时1236公里。
In a statement, Boom Supersonic said the XB-1 demonstrator aircraft climbed to more than 35,000 feet before reaching Mach 1.0.
在一份声明中，Boom Supersonic表示，XB-1验证机爬升至超过35,000英尺的高度，随后达到1.0马赫的速度。
It recorded the speed within 11 minutes of taking off.
它在起飞后11分钟内记录下了速度。
The company also released a video feed of the supersonic test flight.
该公司还发布了这次超音速试飞的视频。
The company said in a press release, “Historically, supersonic aircraft have been the work of nation states, developed by militaries and governments.”
该公司在一份新闻稿中表示：“历史上，超音速飞机一直是国家层面的工作，由军队和政府开发。”
But the latest flight made the XB-1 “the world’s first independently developed supersonic jet” to break the sound barrier, Boom Supersonic said.
但Boom Supersonic公司表示，最近的这次飞行使XB-1成为“世界上首架独立研制的突破音障的超音速喷气机”。
The company’s founder and chief executive officer, Blake Scholl, said, “XB-1’s supersonic flight demonstrates that the technology for passenger supersonic flight has arrived.”
公司创始人兼首席执行官布莱克·肖尔表示：“XB-1的超音速飞行表明，客运超音速飞行的技术已经到来。”
Boom Supersonic launched in 2014 “with the goal of making high-speed travel mainstream and enabling a new world of human connection.”
Boom Supersonic成立于2014年，“旨在让高速旅行成为主流，开启人类互联的新世界。”
With that in mind, the company has been working to develop a supersonic passenger airliner called Overture.
考虑到这一点，该公司一直在努力研发一款名为Overture的超声速客机。
The aircraft would carry up to 80 passengers.
这种飞机最多可搭载80名乘客。
Boom Supersonic is one of several American companies seeking to develop supersonic flight vehicles.
Boom Supersonic是几家寻求开发超音速飞行器的美国公司之一。
NASA is also working on a supersonic aircraft in partnership with a U.S. contractor.
NASA还在与一家美国承包商合作研发一款超音速飞机。
The last time supersonic travel was available to passengers was 2003.
上一次乘客能够乘坐超音速交通工具是在2003年。
That is the year the Concorde – the world’s first supersonic passenger jet aircraft – stopped service.
那一年，世界上首架超音速客机——协和式飞机——停止了服役。
Britain and France jointly operated the Concorde.
英国和法国联合运营协和式飞机。
But the joint operation between British Airways and Air France suffered several business difficulties that led to the decision to stop flying the supersonic planes.
但英国航空公司和法国航空公司的联合运营遭遇了若干业务困难，导致决定停止超音速飞机的飞行。
Some of the difficulties were linked to publicity about a deadly Concorde crash in 2000.
一些困难与2000年协和式飞机致命坠毁事件的媒体报道有关。
That incident involved an Air France airliner crashing shortly after taking off from Paris.
那起事件涉及一架法国航空公司的客机从巴黎起飞后不久坠毁。
The crash claimed a total of 113 lives.
这次坠机共造成113人丧生。
Boom Supersonic says its planned Overture airliner will be designed to transport passengers from the U.S. East Coast across the Atlantic to Europe in about 3-and-a-half hours.
Boom Supersonic公司表示，其计划中的Overture客机将设计为能在约3个半小时内将乘客从美国东海岸跨越大西洋送达欧洲。
The flight with normal passenger jets takes about eight hours.
乘坐普通客机的飞行大约需要八个小时。
Amy Marino Spowart is the president and chief executive officer at the National Aeronautic Association.
艾米·马里诺·斯波瓦特是全国航空协会的总裁兼首席执行官。
She told The Associated Press the latest supersonic test flight suggests “the future of aviation is here and now.”
她告诉美联社，最新的超音速试飞表明“航空业的未来就在当下”。
Spowart added, “Not only is there hope for faster and better commercial flight, but Boom proves that it can be done sustainably.”
斯波瓦特补充道：“不仅更快速、更优质的商业飞行有望实现，而且Boom公司证明了这是可以可持续地做到的。”
Boom Supersonic has said its planned supersonic airliner will be designed to run on up to 100 percent sustainable aircraft fuel.
Boom Supersonic公司表示，其计划中的超音速客机将设计为能够使用高达100%的可持续航空燃料运行。
Such sustainable fuels are made from non-petroleum products, such as food waste or other biomass materials.
这种可持续燃料由非石油产品制成，比如食物残渣或其他生物质材料。
Both XB-1 and Overture are made mostly from a carbon-based composite material to provide “a strong, lightweight structure,” the company said.
该公司表示，XB-1和Overture主要由碳基复合材料制成，以提供“坚固轻巧的结构”。
NASA’s supersonic aircraft – built together with Lockheed Martin – is called X-59.
美国宇航局的超音速飞机——与洛克希德·马丁公司共同建造——被称为X-59。
It is also an experimental plane that is seeking to test the level of noise produced by supersonic travel.
它也是一架实验性飞机，旨在测试超音速飞行产生的噪音水平。
Currently, supersonic flights are banned over land because of the loud noise they produce.
目前，由于超音速飞行产生的巨大噪音，陆地上空禁止进行超音速飞行。
NASA has explained it plans to carry out testing this year of the X-59 aircraft, which has been designed and engineered to operate at lower noise levels than other supersonic aircraft.
美国国家航空航天局已经解释了计划在今年对X-59飞机进行测试，该飞机的设计和工程制造旨在使其运行时噪音水平低于其他超音速飞机。
The tests – to take place at supersonic test centers in California – are designed “to prove the quiet supersonic technology works as designed.”
这些测试将在加利福尼亚州的超音速测试中心进行，旨在“证明静音超音速技术按设计运行”。
NASA said that after that testing is done, the agency plans to begin community reaction studies, beginning in 2026.
NASA表示，测试完成后，该机构计划从2026年开始进行社区反应研究。
These will involve flying the X-59 over several cities and then asking people on the ground to share their thoughts on the level of noise they heard.
这些测试将涉及让X-59飞越几个城市，然后请地面的人们分享他们对所听到噪音水平的感受。
NASA has said the X-59 – which measures 30 meters long and nine meters wide – is expected to fly at 1.4 times the speed of sound.
美国国家航空航天局表示，X-59飞机长30米，宽9米，预计飞行速度将达到音速的1.4倍。
That is about 1,500 kilometers per hour.
那大约是每小时1500公里。
