以5倍于音速的飞行一直是人们带有科幻色彩的梦想,但随着相关技术的不断进步,这个梦想正在照进现实。美国洛克希德一马丁公司的工程师正在研制标志性的“黑鸟”远程侦察机SR-71的继任者SR-72,速度可达到6马赫,相当于每小时7350千米。6小时内环游世界“黑鸟”曾凭借3马赫的速度创造飞行速度纪录。设计上的SR-72速度是SR-71的2倍,可达到每小时7350千米。SR-72被形象地称之为“黑鸟之子”。它的飞行高度可以达到2.4万米,能够在6小时内环游世界,可以充当一个重要的作战武器。凭借惊人的速度,
Flying at 5x the speed of sound has always been the dream of people with a science fiction color, but as the related technology continues to evolve, this dream is being factualized. Engineers at Lockheed Martin are working on the SR-72, the successor to the iconic “Blackbird” long-range reconnaissance aircraft SR-71 that can reach Mach 6 at speeds equivalent to 7350 kilometers per hour. Travel around the world within 6 hours “Blackbird ” has created a speed record with Mach 3 speed. Designed SR-72 speed is 2 times the SR-71, up to 7350 kilometers per hour. SR-72 is vividly called “the son of blackbirds.” Its flight altitude can reach 24,000 meters, can travel around the world in 6 hours, can serve as an important combat weapon. With amazing speed,
