how does a stealth aircraft work?i also want to know its features?

Answer 1

No stealth aircraft work the same. Every stealth aircraft is designed differently and is optimized for its role.
The f-117 was designed as an attack aircraft that did not have a radar or any other electronic equipment that could give it away. It used angular design to deflect radar away from the aircraft, and radar absorbent paint to help even more, but it is not perfect and the air force must use a piece of software to determine the path they must fly to stay a safe distance away from radars that can detect it. It also has a device which mixes cool air with the exhaust in order to make the infrared signature lower.
The B-2 bomber is a tactical nuclear bomber. It uses a form of radar that uses antenna mounted on the leading edge which makes it harder to triangulate its position.It need this radar in order to fly in close proximity to the ground if needed, and also for attacking targets that cannot be bombed using laser guided or gps bombs.
The body of the B-2 is made of dielectric material, which allows radar to pass through the skin. under the skin are special matrix's made of carbon which absorb and trap radar energy. this allows for the bomber to have a certain aerodynamic shape that would otherwise be non stealthy.
The most overlooked stealth aircraft is the B-1. It has radar absorbant paint tailored to absorb the radar frequencies used by fighters, and has its engines set behind a sepentine inlet to stop radar frombeing reflected off the blades of the engine. It also has the worlds most powerful jamming equipment, which is so powerful, it can actually jam all of the other equipment onboard the B-1. This was the first main line stealth aircraft, but this approach at stealth has been abandoned because the B-1's jamming actually alerts the enemy that there is something nasty nearby that is about to attack.
The Technology for the F-22 and JSF have not been released yet.
Something Id like to point out is that the US is not the only country with airborne and spaceborne radar. Russia, china, the UK, Germany, India, North Korea, Japan, South Korea, Taiwan, Saudi Arabia, Qatar, Italy, and at least 5 more countries have airborne radar. The US and Russia have spaceborne radar.

Answer 2

There are two basic methods at work in stealth technology. The first is the prevention of reflection by the use of radar absorbant materials and the avoidance, or masking, of typical reflectors like included corners and turbine blades. The second method is causing reflections to be at very specific angles which are not back towards emitters.

You can see this in the F117 which had a flat underside which would only reflect to a radar right below it, airborne radars would tend to have their signals reflected upwards and not back to the aircraft.

Infrared stealth is achieved by cooling and diffusing the engine exhausts.

Features? They are aircraft, they fly through the air and carries stuff.

Stealth is just a low observability technology, there is still some radar return, there is still some infrared emission. Passive methods aren't currently very effective, but as detector resolution improves so does the effectiveness of these systems. Sensitivity of IR sensors is increasing too. It's an arms race and today's magic bullet is tomorrow's old junk.

Answer 3

There are several methods an aircraft uses to be "stealth". A lot of them are classified, but some are well-known. First, it uses special coatings on its surface that absorb, rather than reflect the electronic beams projected at it from a radar source. Second, since the coating and other surfaces like the cockpit windows can't completely absorb the radar beam, the aircraft is designed with a lot of surfaces that scatter the beam so it doesn't reflect back to the source. You can see this on the F117 Stealth Fighter and the now-cancelled Comanche attack helicopter. They have all kinds of odd-shaped surfaces and zig-zag seams between things like the canopy, bomb bay doors, or landing gear doors and the fuselage or the landing gear doors and that reflect the radar beam in all sorts of directions. Third, the jet exhaust from the engines is mixed with cold ambient air in order to cool it down before it leaves the aircraft so that it is less-visible to heat-seeking tracking devices and missiles. Fourth, there are systems on aircraft that beam signals back toward the radar tracking device that jam, or confuse the enemy device, the electronic equivalent of spraying pepper spray in the eyes of a mugger. No aircraft are completely invisible, because they can be seen by the naked eye and heard by the naked ear, but the idea is to make the image that is picked up on tracking devices so small and hard to track that by the time the enemy figures out what is coming at them it's too late.

Answer 4

Like any other plane but the engines are hidden within the body to stop it from being trcked by heat seekers, there are 3 stealths that i know of, the F-117 NghtHawk stealth bomber,The B-2 Spirt stealth bomber and the F-22 Raptor stealth fighter. in the case of the F-117 and F-22 the plane is dimond shaped so it abbsorbes and makes the plane look like a big bird to radar.

Answer 5

It is designed to absorb signals that are emitted from radar antennas rather then reflect them. This is accomplished mostly by shape (sort of like a log periodic antenna) and type of paint. It can, however be detected by space based, or air born radar which does not look for a reflection, instead it looks for the signal to be missing. (I believe the US military is the only people with space based or air born radar) It can also be detected by passive radar. Passive radar is a system that collects all the forms of radio signals that are present in the air, and can tell when a plane flys through them.

Answer 6

It's designed in -- and the specifics are classified. Basically it's a combination of shape, materials, coatings, and engine exhaust masking.

Ahmadinejad? Thats a sneaky trick but we ain't gonna fall for it.
