That plane will fly as high as 55,000 feet – far higher than normal planes – and make a sound of only 60 decibels. That's far less than the 90 decibels thrown out by Concorde, and is roughly in line with a car on the motorway or a busy restaurant.
新型超音速飞机将在17000米的高空飞行,飞行高度比普通飞机要高得多,其发出声音只有60分贝,远小于协和式飞机的90分贝,与高速公路上行驶的汽车和热闹餐馆里的音量大致相当。
“Now you're getting down to that level where, as far as approval from the general public, it would probably be something that's acceptable,” said Peter Coen, project manager for NASA's commercial supersonic research team, in a new Bloomberg report.
美国航空航天局商用超音速飞机研究团队的项目经理彼得•科恩在彭博社的新报道中指出,“现在我们已经要成功了:只要公众同意,新型飞机就很可能被大家接受”。
If that allows the team to get approval, it hopes to have full-sized versions of the planes to try out by 2022.
如果该团队能得到公众支持,那么有望在2022年前对原型飞机进行测试。
