新东方快车 美国将着手研制超超音速飞机——“新东方快车”。随后,英国宣布将实施同样的计划。这有可能使今后20年成为自莱特兄弟发明飞机以来航空界变化最大的20年。 新东方快车发动机将以氢为燃料;起降将利用现有的跑道;其巡航速度为12马赫至20马赫,飞行高度为3万米至10万米(协和式的高度为1.8万米、波音747为1万米、DC——9为7500米)等。新东方快车的最为引人注目之处,自然是它那令人难以想象的速度了。它的最低巡航速度每小时1万公里以上;按最高速度,则绕地球一圈也不到两小时,这真要使人发出“地球太小了”的感叹。如今从华盛顿经纽约飞往东京,单程约12小时至14小时,超超音速飞机将使它所需的时间一下缩短
New Oriental Express America The United States will embark on the development of the supersonic aircraft - “New Oriental Express.” Subsequently, Britain announced that it will implement the same plan. This could make the next 20 years the most dramatic 20 years since the Wright brothers invented the aircraft. The new Oriental Express engine will be powered by hydrogen; taking off and landing will make use of existing runways; its cruising speed will range from Mach 12 to Mach 20 and flight altitudes will be 30,000 to 100,000 meters (Concord height 18,000 meters, Boeing 747 For 10,000 meters, DC - 9 for 7,500 meters) and so on. The most striking aspect of the New Oriental Express is, of course, its incredible speed. Its minimum cruising speed is more than 10,000 kilometers an hour; by maximum speed, it takes less than two hours to circle the Earth. This really makes people feel “the earth is too small”. Now flying from Washington to Tokyo via New York for about 12 hours to 14 hours a way, the Sonics will shorten the time it takes
