Analysts say the U.S. Black Hawk helicopters crashed or invisible from the windscreen coating
crashed helicopter tail rotor strange five-leaf design, so invisible,” Black Hawk “Exposure in the world
no sound, without any warning. U.S. Seals fall from the sky, a successful raid and kill Osama bin Laden. All this may have benefited from the U.S. military’s top-secret weapons – stealth helicopter.
learned that this is put on invisible “vest” top secret U.S. military helicopter, had never been exposed to is an upgraded version of “Black Hawk.” The end of commandos in action after the bombing in which a helicopter crashed, precisely to prevent leakage of secret information.
strange helicopter crash leaves five tail rotor design, and it would rule out a U.S. military helicopter all open models. Photos show, the helicopter tail, tail boom and tail rotor hub fairing, swept wing and tail rotor stability, “dishwashing basin” cover (tail rotor has five blades) of the invisible structure is very obvious. In addition, the helicopter tail is also covered to reduce the infrared signature of a special heat-absorbing coating.
retired U.S. Special Forces pilots that the fuselage, nose and tail of many similar modular components so that the shape of this helicopter is very special. Former U.S. Defense Department official, deputy director of the Lexington Institute Daniel Gul said: “This is a new helicopter, you have not noticed it in time, came in front of you. The aircraft may fly very fast, can fly at low altitude, from a distance you could hear the sounds of it, so you react, it may be too late. “
United States,” International Defense Technology ” magazine editor Bill Sweetman estimates, which may be substantially modified after the MH-60-type “Black Hawk” helicopters. Stealth version of “Black Hawk” and use stealth technology similar to F-117 stealth fighter. Its shape with the traditional “Black Hawk” helicopters big gap between the chiseled edges and F-117 structure is very similar.
from the technical means, the United States to active duty secretive special operations helicopters and even specially modified to develop a new model, without any problems. At least the U.S. military through the development of “Comanche” This stealth helicopter, had accumulated a wealth of experience and technical reserves.
was canceled in 2004, “Comanche” RAH-66 stealth helicopter program, a stealth helicopter have been widely used technology. Compared with fixed-wing stealth technology, the helicopter usually pay more attention to noise and infrared signature. On the one hand, by increasing the main rotor and tail rotor blades to reduce noise; the other hand, can change the aerodynamics and flight control changes to reduce noise. Reduce the infrared signature of the measures is essential – “Comanche” RAH-66 Stealth helicopter once in the end beam with complex exhaust system.
cross-sectional area to reduce anti-radar, “Black Hawk” helicopters to transform the original windscreen. However, retired Special Forces pilot that, if added to the windscreen coating is likely to increase the pilots wearing night vision goggles when handling the helicopter more difficult. Some experts speculate that it is wind and cast coating affected the pilot’s attention, resulting in invisible “Black Hawk” of the fall.
recognized as a world power in helicopter production technology, such raid on bin Laden’s strategic actions, the U.S. stealth “Black Hawk” helicopter is still failure and exposure to the world. This fully shows that the helicopter modification or the birth of a new model of technology to face the extent of risk. Therefore, some experts believe that the development of the U.S. military no longer invisible, “Comanche” helicopter, largely for this reason.
