Stealth aircraft (stealth)
Technological developments continue growing at this time, competition is one of the technological advances of other technologies also continued to compete with each other. Scientists in their field of competition to create the technology that can emulate the results of an existing copyright technology is the part that is not separated from development.
Stealth technology is a technology now being widely developed in the use of technology in the military. This development includes war tools or radar transmitter and its instrumentalist to catch wave radar stealth tools.
In development, the stealth technology used in devices in aircraft, ships, and also missile (projectiles / weapons). Stealth aircraft (stealth) or called the plane is very quiet aircraft designed to absorb and deflect radar uses stealth technology, making it more difficult to detect. In general, the goal is to launch an attack while he was still outside enemy detection. F-117 Nighthawk is one type of stealth aircraft which used the United States Air Force in the Gulf War.
Stealth aircraft have the ability to avoid detection, visual detection, audio, heat sensors, as well as radio waves (radar). Visually, the planes more difficult to see if have same color as the background color (camouflage). In the audio, of course, trying to make the plane more calmly. In the heat sensors, aircraft are usually detected from the heat arising from the body or from the surrounding air temperature. Hottest part of the plane is usually a channel air exhaust or engine exhaust and the leading edge (the first part of the aircraft through the air). Heat from the exhaust can be reduced by mixing with a blast of cold air machine from the outside of the fuselage before exhaled out of the plane and extend the exhaust pipe (such as A-4 Sky hawk exhaust Indonesia which have longer than the standard version). Exhaust part is usually pursued by anti-aircraft missiles with infrared sensors. However, modern heat-seeking missile is now also having the ability to detect and chase the heat generated due to friction with the air surface of the fuselage.
Detection of radio waves is a way to prevent radio waves from the radar is not reflected from the body of the plane and returned to the radar. Radio waves can be absorbed if the coated fuselage RAM (radar absorbent material), is reflected in the other direction, or such that these waves become lost or mutually exclusive (this is what underlies the form of stealth aircraft which have a shape other than ordinary aircraft or a bit weird).
Stealth aircraft are usually not 100% undetectable by radar. But because it has the RCS (Radar Cross Section) is small, on the radar screen only visible for hordes of birds, not planes.
In the construction of the fuselage of the F-22 identified no two surfaces or lines that intersect perpendicularly. Front and rear side (leading edge and trailing edge), wing and stabilizer (tail) for example, tilted back with a certain angle. Fault wing and tail tip contour was not a ninety-degree angle. In fact, two vertical stabilizers attached to the fuselage with a tilted position, so that when viewed from the front or rear looks shaped "V".
Specific patterns in the construction of the F-22 aircraft are part of the implementation of stealth technology (stealth technology) on the Raptor. Sloping surface will deflect radar waves to bounce back is not caught by a receiver unit (receiver) radar. Conversely, the intersection is perpendicular to tend to create a flat surface which is a good reflector for radar waves. With the reflection of radar wave magnitude spend RCS (radar cross section), a factor which becomes a measure of how large the target object detected by radar, relegated to minimize the possibility of the existence detected plane.
However, with only regulate the outer shape of the aircraft; aircraft stealth characteristics will not be optimal. Besides being a radar wave deflection (probably) not fully effective there are also parts of the plane potential to be marker detection radar can not be reduced through the design of the fuselage, as part of the cockpit and engine. Therefore, the F-22 (and generally stealth aircraft), the implementation of stealth technology is done by combining various methods or ways.
The conclusion that can be obtained from the introduction of stealth technology, among others:
1. Fundamental principles of stealth technology that is by diverting or absorbing the radar so that the radar did not come back perfectly to the radar transmitter, so the tech stealth aircraft appeared on the radar screen is no longer shaped like a large aircraft but only small dots like a bird 2. Shape in the form of stealth aircraft technology unlike any other carrier aircraft, but made the arches in the form of sharp corners and area-arc radar so that the radar in order to reflect radar waves scattered arbitrary 3. Material coating material in aircraft stealth technology, there are materials that can absorb the radar so that the radar did not return to the radar transmitter is not perfect.
Introduction and information about stealth technology can inspire to complement or develop similar technology can create even more advanced technology anymore.
