SR-72?只看名字就应该与大名鼎鼎的SR-71黑乌侦察机有关。美国《航空周刊》近期披露了洛克希德·马丁公司(简称“洛·马”)正在“秘密”研制的SR-72高超音速无人侦察机计划,而洛·马官网上也提及了这一报道。该报道指出,被称为“黑乌之子”的美军下一代高速侦察机SR-72将由洛·马下属的臭鼬工厂负责研发,用于承接上世纪70年代研制的SR-71的侦察任务。不过与有人驾驶、最高速度超过3倍音速的SR-71不同,SR-72为无人机,动力采用涡喷-双模冲压的组合发动机概念,能实现高超音速飞行,最高飞行速度可达6马赫,也就是声音速度的6倍,相当于现今第四、第五代战斗机速度的3倍,比一般的防空导
SR-72? Just look at the name should be with the famous SR-71 Black Wu reconnaissance aircraft. Aviation Weekly recently disclosed plans for the SR-72 hypersonic unmanned reconnaissance aircraft Lockheed Martin (“Loma”) is developing under the name of “Secrets,” while Lockheed Martin’s official website Mention this report. The report points out that the next U.S. high-speed reconnaissance aircraft SR-72, known as the “son of black and black,” will be developed by Lockheed Martin’s skunk factory to undertake reconnaissance of the SR-71 developed in the 1970s task. However, unlike the manned SR-71, which has a top speed of more than three times the speed of sound, the SR-72 is a drone, powered by a turbojet-twin-die ramjet engine concept that enables hypersonic flying at up to 6 Mach, which is 6 times the speed of sound, equivalent to the current fourth and fifth generation fighter speed 3 times faster than the average air defense guide
