速度高达15倍音速计划投入7亿美元据美国《太空即时新闻》报道,美国航空航天局(NASA)目前正在与其他研究机构共同开发极超音速飞行器“超级X”,速度是音速的10～15倍,计划20年内使之成为现实。据报道,这种新型飞行工具将为国际旅行、商务和太空旅行带来无限前景从美国的机场起飞,在不到2小时内就能降落在世界上任何一个机场;或是从地面机场起飞,到国际空间站上游览一番再迅速返回地面。这些通常要花上几天或数周时间的旅行,将由于科技的发展而大大缩短。
NASA is currently working with other research institutes to develop the “Super X”, a supersonic aircraft, at a speed of 10-15 of the speed of sound, according to the U.S. space-time news report. Times, plans to make it a reality within 20 years. It is reported that this new type of flying tool will bring unlimited prospects for international travel, business and space travel from the United States airport, in less than two hours landed at any airport in the world; or take off from the ground airport, Visit the International Space Station and then quickly return to the ground. These trips, which usually take days or weeks, will be greatly reduced by the development of science and technology.
