Modern Technology At Stealth Aircraft


 Do you Know ??
Progress of time to make more rapid aerospace technology development, at present there are three strong sides in the world with highly advanced technology aircraft.

The first is of course the United States, second is Europe and most recently Russia. All three compete to create a fighter with more advanced technology than others.

For stealth affairs who led the United States remains, while Russia can not be considered lightly with maneuverability advantages.

Although America has also developed technology that is not less speedily maneuvers with Russia as the application of Thrust vectoring, which is where the "exhaust" the plane can twist into any arah.tapi between all these technologies will be discussed here is about how the aircraft got the nickname Stealth.

Russian stealth aircraft







There are a few recent American-owned aircraft in this category, namely the F-117, F-22, JSF F-35, and B-2.

For Stealth own affairs can in akali the manufacturer with a design which minimizes plane curve whose function is to minimize sharp angles that can be caught by the radar and appear at the RCS (radar cross section).

There are also the aircraft that has been lightly worn like F/A-18 Hornet (though not really because it has undergone an upgrade aging more than 30 percent) that covers some part on his aircraft with radar-like coating on the ends The main wing and part of his ruder.

How it Works Aircraft Using Stealth System ( invisible )


In the picture above A F-117 aircraft to avoid radar because the design of the aircraft has a minus indentation so that the radar is coming from the enemy will at pantulkan so that appears on the monitor RCS enemy is just the dot-dot (the dots) is very small which could be considered as hordes of birds and not the aircraft that was slipping.


Similar to the workings of Swallow


Aircraft without stealth system (invisible)


This second picture is an F-15 Eagle that the design has many sharp curves on her body so it can catch in the radar well and appear in the monitor as a dot-dot RCS fighters who infiltrate.

Maybe that's easy to picture why a plane can get away from security monitor enemy, however, an aircraft the F-117 proved to have weaknesses as well, during the Yugoslav conflict, the aircraft caught radar and missiles shot down by SA-3 SAM-made Russia.

It turns out that at the time of the crash of his bomb bay (door bomb) in an open, so maybe that's sharp corners which was caught by radar later in the attack with surface-to-air missiles (surface-to-air missile).

In conclusion, it would need improvement in each generation fighter aircraft, with the completion of a state party to reduce the number of fatalities is falling.

American Stealth aircraft






To achieve the "stealth" there are 3 methods are currently known:

    1. Engineering form (shape) as forms of F117.
    2. Engineering materials (radar absorbant material) as in U2 (early generations).
    3. Engineering other technologies: plasma stealth, the effect first appeared in the Russian sputnik satellite, but for the plane apparently still a secret.

However, his ultimate goal to be achieved besides stealth invisible on radar, also invisible to the eye (like a chameleon) and is currently in the research.

If no one ever appeared on National Geographic TV show about it, using laser technology and engineering materials to bend light that should be reflected so that the object behind the object become visible (objects become transparent).

Over time, radar technology was developed to be able to detect stealth aircraft, such as radar 'radio', acoustic, infrared radar, radar thermal (heat), weather radar (at least, can detect the air when the plane crossed tubulensi).
