Natural Science Forum / Physics / General Physics / July 2008? about the math behind stealth
I remembering watching a TV show about the creation of Stealth technology. There was a comment about how the engineers at Northrup pretty much had figured out how stealth worked mathematically. But, there was a piece missing. Apparently, there was a published Russian mathematician about "unifying" the magnetic & electrical field. Or some such theory that helped perfect the stealth technology. I'm trying to tap the wisdom of the group to see if anyone can provide a reference to this mathematician, his work, and help me research this. Thanks. -brad walker On Jul 17, 4:05 pm, brad2...@gmail.com wrote: > I remembering watching a TV show about the creation of Stealth > technology.

Think of a transmission line - you ened to terminate the signal so that there is no reflection. That's where the paint and no corners comes in.Finding the right materials is the tricky thing. Can't have been too difficult if the Yanks worked it out now can it? K. On Jul 16, 10:42 pm, kronec...@yahoo.co.uk wrote: > I don't think there is that much to it.

Well said, kronec! The Educational System here in the USA is abominable. People are constantly admitted for "Multicultural Equality", an Educational Mafia is primarily concerned with its own Jobs, Ingenious Imitation replaces Creative Genius, and so on. While almost every University in the U.K. has high standards in the sciences, mathematics, and engineering, the only USA Universities that even have tolerable standards are: Princeton, Stanford, Chicago, MIT, CalTech, U. Florida northern campuses, U. Maryland, Johns Hopkins U., U Texas Austin, U. California San Diego, U. Missouri Columbia, Rutgers U., U. North Carolina, and the Military Academies (regarded as a single entry) including West Point and Annapolis and the Air Force Academy. Harvard used to be good but is now dominated by social science and humanities departments, while U.C. Berkeley is in a similar difficulty or worse. I've recently removed U. Virginia and George Mason U. Virginia from my list of tolerable USA Universities. Osher Doctorow |I remembering watching a TV show about the creation of Stealth | technology.

"Stealth technology" is a buzz word for a radar mirror, the math behind it is this: http://aic.stanford.edu/jaic/img/jaic32-03-006-fig002.jpg On Jul 17, 12:05 am, brad2...@gmail.com wrote: > I remembering watching a TV show about the creation of Stealth > technology.

Well, the big piece missing is that they also figured out how radar iself work's mathematically. So stealth works's just like engineers at Northrup do. It's work fine until some other engineers invent GPS, Adaptive AI, Drones, and laser-guided bombs, > Apparently, there was a published Russian mathematician about > "unifying" the magnetic & electrical field.

The mathemtaical basis of stealth technology was derived by Pyotr Ufimtsev, "Metod Kraevykh Voln v Fizicheskoi Teorii Difraktsii (Method of Boundary Waves in the Theory of Diffraction), (Moscow: Sov. Radio), 1962. The 242 page dense mathematical treatise was publically released by the Soviets without classification.

On the same stealth subject, could someone comment on what the author says in this article... http://www.ocnus.net/artman2/publish/Defence_Arms_13/The_Plane_That_Would_Bomb_I ran.shtml He says, "An electric current runs from one end of the plane to the other. This forces radar that hits the plane to skim across the wings rather than bounce off and send a signal." Does this sound right? | On the same stealth subject, could someone comment on what the author | says in this article... http://www.ocnus.net/artman2/publish/Defence_Arms_13/The_Plane_That_Would_Bomb_I ran.shtml | He says, "An electric current runs from one end of the plane to the | other.

Unless the plane is a receiving antenna it sounds more like cannabis. Imagine you are in a darkened chicken coop with a flashlight and a catapult, trying to hit a flying chicken. You have some success until the chicken starts to carry a mirror which reflects the walls of the coop back at you. You can't see the chicken, instead you see the walls and ceiling of the chicken coop as you sweep the flashlight around, searching. That's one stealthy chicken. The stealth's flat surfaces are mirrors to radar, what you get back is reflected clutter that you cannot lock onto and recognise as friend, foe or chicken.
