The principle of Stealth Aircraft

In principle, so that the plane was a stealth (invisible) dalah how to reduce the Radar Cross Section (RCS), which appear on radar. Steps to be done is to make the design of the plane such that the surfaces of aircraft as small as possible reflect the emitted radar energy to be recaptured by the radar antenna. Even if necessary form the plane did not reflect radar energy. If reflected, labored to bounce radar energy is directed in another direction so that if one is caught again, at least only a small portion. For that, the plane made a strange shape not as usual. As an example, the form of B-2 aircraft which has a range that is as long range DC-10 aircraft but made for flat and curved shape in the middle of the body. With this form, in addition to the radar beam velocity is slowed down also gives the reflection effect in all directions.
Wing shape also affect the reflection of radar energy emitted. Form of the old wing straight into the side for example, provide a perfect reflection so that the aircraft is easily detected. on the screen, point the planes RCS looks great.
Given this, then people make sayung wings backward, indeed minimize the reflection but not satisfactory due to the greater RCS, then be made to Delta that makes most of the radar beam on the wing, largely exiled to the other direction. Then made the wings with crescent shape like those of the next-generation planes. By creating an arch in the wing, leading edge, then bounce the other way more perfect.
Another design is to form a plane-sided facet facets kubustik such as eye shape, as in the eyes of dragonflies. Forms are also found on the helicopter on the generation of 1980-1990's as the AH-1 Cobra and AH-64 Apache so that the reflection of radar is not returned to the radar antenna.
Then the general design of stealth aircraft does not permit the pylon or missile or rocket hanger suspended from the body and wings of aircraft such as encountered in the general plane. So that the missile was placed on the shelf-bomb (bomb bay) special.
Another way that is by using a special material known as RAM (Radar Anti-material) that be an energy absorbing material radar beam. The materials include epoxy composites graphyte form of carbon. Because of that, then do not terpantulkan radar energy.
Nevertheless, the bill still is not perfect to fool radar. For example, the F-117 stealth aircraft had been shot down by anti-aircraft missile SAM (Surface to Air Missiles) SA-2 Guideline of Serbia when the NATO air operation in 1999 during the Kosovo conflict.

Stealth aircraft

B-2 Spirit stealth stealth bomberPesawat (English: stealth aircraft) or aircraft called very silent [1] is an aircraft that is 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 that use the United States Air Force in the Gulf War. Stealth aircraft has the ability to avoid detection, both in visual detection, audio, heat sensors, as well as radio waves (radar). Visually, the plane is more difficult to see if has the same color as the background color (camouflage). The audio, of course, trying to make the plane more calmly. 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 typically the channel air exhaust or engine exhaust and the leading edge (the plane that first split the air). Heat from the exhaust can be reduced by mixing the spray engine with cold air from the outside of the fuselage before it is exhaled out of the plane and extend the exhaust pipe (such as A-4 Skyhawk Indonesia which have exhaust is 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 have the ability to detect and chase the heat generated due to friction with the air surface of the fuselage. Detection of a radio wave is to prevent radio waves from the radar is reflected from the fuselage and back to the radar. Radio waves can be absorbed if the fuselage is coated RAM (Radar Absorbent Material), is reflected in the other direction, or such that the wave is lost or mutually exclusive (it is this which underlies the form of stealth aircraft which have a shape other than ordinary aircraft or a little strange .) Stealth aircraft are usually not 100% undetectable radar. But because it has the RCS (Radar Cross Section) is small, only visible on the radar screen for hordes of birds, not planes.

Aircraft reconnaissance

Home Electric Canberra, one type of aircraft or aircraft reconnaissance fighter intai.Pesawat spies (recce or reconaisance) is an aircraft that is used to gather intelligence and surveillance and reconnaissance tactical or strategic positions or other countries opposed to the desired data.Usually there are two types of fighter aircraft such as this which reconnaissance aircraft and fighter aircraft dyang given a reconnaissance role.Reconnaissance Aircraft (Reconaisance) is usually used to collect data versus strategic reconnaissance data, has the ability to infiltrate and fly higher for the missile did not reach the opponent's defense. In its development of stealth technology is also applied to fighter aircraft of this type. Yet the sophistication of missiles and equipment that had opposed making not many countries that operate this type because the cost is too expensive and still vulnerable to missiles opposite example is the U-2 shooting case that infiltrated into the Soviet territory in the 1960s Making some countries use a satellite switch spy.In addition to reconnaissance aircraft specially designed range of U-2 and SR 71 Blackbird (USA), there are also reconnaissance aircraft that also serves as a good patrol aircraft patrolling the air and maritime patrols. This aircraft has a shape similar to civil aircraft or transport aircraft in general, but given the equipment and special equipment. Like the console radar, radome as a radar site in the form of a radar dish on the fuselage or other equipment which has the same function is more sensitive and powerful radar coverage far. The aircraft model is usually used as early warning aircraft (AWACS) or maritime reconnaissance patrol aircraft which also have special expertise to detect even destroy submarines. The planes such as this example is E-3 Sentry, EC-2 Hawkeye, RB-47, B 737 Surveillance (USA), CN-235 MPA (Indonesia), CN-235 Persuader (Spain), Atlantique (France), Il-76 Mainstay (Russia).There is also a fighter aircraft that were modified for the purposes of Reconnaissance. Generally used as a tactical reconnaissance. Equipped with sensors and special cameras such example is the MiG 25 R, RF-5 Tigereye.

History of flight

At first people used kites to scare-tactics to the enemy and to provide information about the position of both friend and foe alike, or even to frighten the enemy. This habit is carried out by the ancient Chinese. Then the kite is equipped with a man to know in detail the position of the opponent. Zeppelin airship invention and also color the development of military aircraft. Used starting from just reconnaissance and used as bombers to bomb enemy positions. Noted that utilize them are German zeppelin to bomb targets in Britain in World War I. In the journey made planes and developed for warfare and air combat battles in particular.

Fighter

Fighter aircraft are military aircraft designed to attack other planes in the air. Unlike bombers, designed to attack targets on the surface. Fighter aircraft are relatively small, fast, and agile. Fighter aircraft originally developed in World War I to face the bomber planes and hot-air balloon that began commonly used for ground attack and reconnaissance. The first fighter aircraft originally a double-wing wooden fed light machine gun. In World War II, more fighter planes made of metal, single-winged, and use machine guns that are embedded in the wings. After World War II, began to replace the turbojet engine piston engines, and missiles began to be used to replace the machine gun as primary weapon.
The classification was made based on the generation fighter aircraft. Use of this generation was originally used in Russian defense officials, who called the F-22 Raptor fighter aircraft the United States as a "fifth generation".
Fighter aircraft are used for war planes in the air. Generally, combat aircraft-shaped trim, can move swiftly, to bring canon (machine gun) as well as missiles and bombs, high-speed, equipped with avionics equipment for more than civilian aircraft / passengers such as radar that can detect opponents within the target distance and lock the opponent. Moreover, equipped with radar equipment humbug and vandals, until capable of "stealth" (stealth).
