Stealth
A complex design philosophy to reduce the ability of an opponent’s sensor to detect, track, and attack an aircraft. However, to make stealth work a combination of much technology is required to do so. First of all the wings of an airplane should be smooth and have no 90-degree angles. The engine is also buried inside the body of the airplane to make the airplane quieter. The air intake and exhaust duct are located on top of the aircraft to reduce the heat trail in case of heat seeking airplanes flying below. The most important technology of all is RAM. RAM is radar absorbent material that absorbs radar signals. RAM makes the size of an airplane appear to be the size of a bird if it was to be read on radar. Last of all, ECM is placed in the airplane to confuse radar operators through jamming and using ghost images. I’m sorry that I cannot provide you with more information about stealth technology but all of the other information about Stealth is confidential and my sources are very limited.
The History of Building the First Working Stealth Plane
As far as anyone could remember stealth was first used in World War II. During the time of World War II it was discovered that at above 20,000 feet the shadow of an aircraft could be seen, and it couldn’t be disguised. Engineers actually thought that bright white paint would actually work, but eventually they found out that it didn’t because of the sun. Plus, how the plane cast a shadow on the ground. However, later on engineers soon found out that all they needed was bright incandescent lamps placed under the wings and across the underside. With new light the aircraft were invisible for a few minutes during daylight recon missions, and so stealth was first used. Years later after World War II engineers and aerodynamicists were to build two airplanes called the U-2 and SR-71. These two aircraft were built to be invisible to radar detection which would allow them to spy on other countries. However, they did create the plane there were a few errors. For example, although the U-2 had a low RCS it didn’t have any speed at all. After the U-2 and SR-71, YF-11 project was born. YF-11 was to build the F-117A. Within two years the F-117A was created. This was the first working stealth plane that had a low RCS and was working correctly. For more information on the F-117A click on the button which says STEALTH PLANES.
