自2012年起,NASA就开始研究各类民用超声速概念,能运载乘客并遵守民用航空在噪声领域的各项规定。最终,NASA在加利福利亚州和俄亥俄州对样机进行了风洞测试,并且美国航空航天管理局将民用超声速发动机的验证机项目纳入了其2016财年的预算。2020年,航空噪声管制将变得更加严格。因此,降噪率相对较低的涡喷发动机,典型的如超声速飞机上的发动机,必定难以满足这项新规定的要求。通用电气和NASA已于2014年完成了一个
NASA has been studying various civilian supersonic concepts since 2012 to carry passengers and comply with the requirements of civil aviation in the noise area. Finally, NASA conducted wind tunnel tests of prototypes in California and Ohio, and NASA included the civil supersonic verification program into its FY16 budget. In 2020, aviation noise control will become more stringent. Therefore, relatively low noise reduction turbojet engines, such as the typical supersonic aircraft engines, will certainly be unable to meet the requirements of this new regulation.
