From what I have read, there are a number of principles involved in stealth, beyond the pure math of the dissolution and refraction of waves.
The Nazis did build a couple of prototype 'flying wing' bombers in 44/45(?), and to save money, they types were made out of plywood. There was such
a serious shortage of aircraft metal that actual wood was easier to fabricate. By this point the Nazi's HAD developed a primitive radar copied from
the Brits. They were surprised that the ply structure had an extremely low signature.
Stealth, as far as I have read, didn't really crop up again until the Korean war, when automated radar-directed antiarcraft artillery became an
Much of the work was down in England and at groom lake. The way it was done is to build a scale model of the craft, place it on a pole angled toward
the radar source, and slowly rotate the model and check the signature. It turns out that the theoretical designs often have overtones that are
difficult to predict.
Someone on another site wrote that you can identify a stealth lab from these signs:
1. A large square or circular runway, with asphalt only 2 or 3 inches deep, incapable of supporting a large plane
2. a 5-20 ft. padded pole, often sticking up through a trapdoor, at one side of the field. This would make it unsafe to land a plane or helicopter
3. a movable tent or dome, possibly on a track, to cover the pole, so that the model, when in place cannot be seen by satelites.
The sources I was reading said that much of the model work was done in the U.K., at their premier pilot training facility (can't remember location)
where US pilots often are trained.
They also said that stealth is a craft rather than science; rt after the bomber went public, you notice that the air intakes for the engine had to be
retooled, and the lower edge of the 'glass' on the pilots canopy, which was originally straight, now has a sawtooth edge. The computers said it
wouldn't be a problem, and it wasn't in ground testing, but during flight the air rolling off of those surfaces changes the signature somehow.
I wish I could find the website again. Someone at ATS had linked it in a prior post. (not the Nazis, but the testing. I saw the Nazi stuff on the
