"Coal dust RAM" was just Horton trying to make himself look good in the 80s.
https://airandspace.si.edu/collections/horten-ho-229-v3/stealth/

quote:

Dobrenz and Spadoni explained that, "during our inspection of the Horten 229 at the Smithsonian museum, it appeared that a material similar to carbon black or charcoal was mixed in with the glue between the thin layers of the leading edge shape." After examining the aircraft, the men analyzed sections of the leading edges of the jet's center section using a portable radar reflectometer called the Next Generation Sensor. They compared the Horten data to a plywood sample 2 centimeters (3/4 inches) thick, presumably a 'control sample,' against which the Horten data could be compared. The findings revealed that:

"The Ho 229 leading edge has the same characteristics as the plywood [control sample] except that the frequency [do not exactly match] and have a shorter bandwidth. This indicates that the dielectric constant of the Ho 229 leading edge is higher than the plywood test sample. The similarity of the two tests indicates that the design using the carbon black type material produced a poor absorber."

Dobrenz and Spadoni use the term 'absorber' to refer to the ability of the Ho 229 leading edge to absorb the radar signal rather than reflecting it back to the antenna receiver. More absorption means less reflected signal and greater stealth. The authors assumed in their paper that crafts persons used the "carbon black material" to lower the RCS, however, our technical study findings described above found no evidence of carbon black or charcoal in the Horten jet.

Yea, if the don't lose a blade or have some other catastrophic failure from the impact, the newer drones control software is pretty amazing at recovering from things as long as they have a little bit of altitude to work with.

I noticed several of those incidents involve the drone basically running straight into a building or cliff or some such. Is that due to something in their guidance system glitching out and locking in a constant direction, or is it just the person steering it loving up?

Little bit of column A, little bit of column B.

There are some really bad drone pilots out there, but there's also some really glitchy drone software too. It's often impossible to tell in a video which was which.

Reading through German articles on that thing, "carbon-impregnated plywood" just seems be a reference to the carbon particles in the glue used to laminate the wings. Some sources claim this gave the laminate radar-absorbent properties. Here's a cross-cut:

Great dump!

On the Aussie theme, would anyone like some Connellan Airways (ConnAir) dumps/info? I'm good friends with the family and (with permission) post some cool stuff from the archives the family has. The Connellans are notorious for their pranks and a favourite while in school was being taken hook line and sinker with an old photo framed of the Concorde composited over Ares Rock with the ConnAir logo on it. They called it the Conncorde.

Not my photos but:









I'll touch base with them and see what stuff I can get.

So in the foreground, we have the XB-52. In the middle we have a B-36. Way off in the distance is an F-84. Parked almost off frame to the right is a C-97.

What the HELL is parked behind the port wing of the B-36? I've been searching for like an hour now. I'm normally pretty good at this.

for future reference, I don't know how two beers did it but I saw it had contrarotating props and searched for USAF planes with contrarotating props. Wikipedia had a list and it wasn't hard to spot the Super Savage when I got to that page.

From the wikipedia article on the XF-84H:

wikipedia posted:

Lin Hendrix, one of the Republic test pilots assigned to the program, flew the aircraft once and refused to ever fly it again, claiming "it never flew over 450 knots (830 km/h) indicated, since at that speed, it developed an unhappy practice of 'snaking', apparently losing longitudinal stability".[14] Hendrix also told the formidable Republic project engineer, "You aren't big enough and there aren't enough of you to get me in that thing again".
