Stealth helicopters are helicopters that incorporate stealth technology to decrease an enemy's detection ability. [1] There are a diverse range of technologies used to achieve this decreased detectability; these have largely involved the reduction of several different signatures typically generated by a rotorcraft, including those of noise ...
Stealth aircraft are still vulnerable to detection while and immediately after using their weaponry. Since stealth payload (reduced RCS bombs and cruise missiles) is not yet generally available, and ordnance mount points create a significant radar return, stealth aircraft carry all armaments internally. As soon as weapons bay doors are opened ...
The Boeing–Sikorsky RAH-66 Comanche is an American stealth armed reconnaissance and attack helicopter designed for the United States Army.Following decades of study and development, the RAH-66 program was cancelled in 2004 before mass production began, by which point nearly US$7 billion had been spent on the program.
The presence of supersonic and jet-powered stealth aircraft such as the SR-71 Blackbird indicates that acoustic signature is not always a major driver in aircraft design, as the Blackbird relied more on its very high speed and altitude. One method to reduce helicopter rotor noise is modulated blade spacing. [49]
Journalists have noted design similarities between the RQ-170 and previous stealth and UAV programs such as the Lockheed Martin RQ-3 DarkStar and Polecat. [ 3 ] [ 4 ] An Air Force official said, "It's the same concept as [the RQ-3] DarkStar, it's stealthy, and it uses the same apertures and data links, only it's bigger."
(A stealth missile works in much the same way as an aircraft, employing stealth technology—radar-absorbing material, smooth surfaces, and a flat exhaust system—to make it less observable to ...
The newer, but still 1980s-era B-2 Spirit stealth bomber costs $150,741 an hour to fly. The older and notoriously hard to maintain B-1B Lancer swing-wing bomber costs the most of all at $173,014 ...
At times, the helicopters can fall back as much as a half-mile if the horses and burros are moving in the right direction. And over-populating, now or in the future, can threaten an entire herd or ...
