US-developed missile can not intercept the fastest reconnaissance | Scientific exploration - explore areas Skunk Works (Skunk Works) was founded in 1943, is officially faa recognized faa nickname Lockheed Martin Advanced Development Project, which is world-renowned U.S. high fine tip aircraft "incubator" to act as a secret research program based aircraft, Lockheed Martin developed a number of famous aircraft products, including the U-2 "Dragon Lady" high-altitude reconnaissance aircraft, SR-71 "Blackbird" high-speed reconnaissance aircraft and the F-117 "Nighthawk" stealth fighter, F-35 "Lightning" II stealth fighter, F-22 "Raptor" faa stealth fighter and RQ-170 "Beast of Kandahar" stealth drones, faa etc. June Skunk Works leaked promo for the first time Lockheed Martin's sixth-generation fighter program.
Skunk Works developed SR-72 reconnaissance aircraft, said the biggest difficulty is to coordinate the work of state of the two engines, namely, how to make up the gap between the speed of the engine turbojet and scramjet between, because turbojet aircraft can only be accelerated to Mach number of 2.5, while the minimum ignition speed is usually for scramjet Mach 3 to 3.5. To this end Skunk Works spent seven years has finally achieved a major breakthrough in support of HTV-3X "black swallow" Project, developed a lower firing rate (less than Mach 3) of the scramjet , but also some other techniques can be used to enhance the performance of turbojet aircraft speed can make up to Mach 4.
