6th GENERATION STEALTH AIRCRAFT

Stealth aircrafts are aircraft that use stealth technology to avoid detection by employing a combination of features to interfere with radar as well as reduce visibility in the infrared visual, audio, and radio frequency (RF) spectrum. While no aircraft is totally invisible to radar, stealth aircraft prevent conventional radar from detecting or tracking the aircraft effectively, reducing the odds of a successful attack. Stealth is the combination of passive low observable (LO) features and active emitters such as Low Probability of Intercept Radars, radios and laser designators. These are usually combined with active defenses such as chaff, flares, and ECM. Stealth refers to the act of trying to hide or evade detection, For airplanes, stealth first meant hiding from radar. It is not so much a technology as a concept that incorporates a broad series of technologies and design features. This paper shows the development of stealthy airplanes which teaches several important lessons about technology. The first is that often many different technologies like Nano-Technology with Aerodynamics must be combined to achieve a desired outcome. An advance in one field, such as materials or aerodynamics, must be accompanied by advances in other fields, such as computing, constructing or electromagnetic theory. The second lesson is that sometimes trial and error techniques are insufficient and advances in mathematical theory are necessary in order to achieve significant advances. Finally, stealth teaches the lesson that technology is never static - a "stealth breakthrough" may only last for a few years before an adversary finds a means of countering it. So this paper deals with how to handle the Stealth. This paper also shows how and where to use Nano-Technology.
