| 説明 | (National Museum of the United States Air Force collection, Wright-Patterson Air Force Base, Dayton, Ohio, USA)----------------------From exhibit signage:NORTHROP TACIT BLUEBuilt in the early 1980s in great secrecy, the revolutionary Tacit Blue aircraft tested advanced radar sensors and new ideas in stealth technology.Tacit Blue proved that a stealthy aircraft could have curved surfaces - unlike the faceted surfaces of the F-117 Nighthawk - which greatly influenced later aircraft like the B-2. Tacit Blue's design also minimized the heat signature emitted from the engines, further masking its presence. Tacit Blue was aerodynamically unstable, but it had a digital fly-by-wire system to help control it.With its low, "all-aspect" radar signature, Tacit Blue demonstrated that such an aircraft could loiter over - and behind - the battlefield without fear of being discovered by enemy radar. Using advanced sensors, it could also continuously monitor enemy forces (even through clouds) and provide timely information through data links to a ground command center. Moreover, these sensors functioned without giving away the location of the aircraft.The Tacit Blue aircraft flew 135 times before the program ended in 1985. The aircraft was declassified and placed on display at the museum in 1996.The Tacit Blue aircraft was nicknamed "The Whale" for its unusual shape. Also, the single engine intake on the top of the fuselage was reminiscent of a whale's blowhole.A plaque mounted in the cockpit recognizes these Tacit Blue pilots:Mr. Richard ThomasColonel Don CornellLieutenant Colonel Russ EasterLieutenant Colonel Keny DysonMajor Dan VanderhorstTECHNICAL NOTESENGINES: Two Garrett ATF3-6 high-bypass turbofan enginesDESIGN OPERATIONAL SPEED: 287 miles per hour / 250 knotsOPERATING ALTITUDE: 25-30,000 feetCREW: OneWEIGHT: 30,000 pounds---------------------- |
