I have – I *think* – just corrected an error in the listing that should open sales up worldwide. If some of all y’all furriners would like to take a look and see if it’s still unavailable, that’d be helpful. Note, though, that USBP#02 has been uploaded and is going through review… and – again I *think* – should be far better in terms of image resolution. If I get confirmation from a customer or three that #2 is better than #1, I will re-upload #1. I don’t know if previous purchasers can download the new, better version or not…

#2 took freakin’ *forever* to get properly formatted. I couldn’t find a way to get the “Caliber” converter on my computer to *not* reduce the image resolution, so I had to use the Amazon system directly, which meant uploading the thing and waiting for it to process, then looking through the annoyingly slow previewer for the innumerable and mysterious formatting issues. After around 20 cycles of this, I *think* I’ve got it hammered into shape with full-rez images. So while this is formatted and laid out differently from the standard PDF version, the image quality should be as good.

Unless something screwy happens (and, gosh, when has *that* ever happened), USBP#2 should be available on Amazon in the next some hours. I have high hopes of being asleep at the time.  So if you’d like to be the first kid on your block with a copy, or want to help out be getting a copy early and providing feedback (if so, thanks), just search for “US Bomber Projects” on Amazon.

 

My plan at this time is to keep publications at Amazon about five or six issues behind those on my website.

I have gotten some feedback by buyers of US Bomber Projects #01 on Amazon for the Kindle. Not a lot, but some. Half of the feedback is “Amazon won’t let me buy it because of where I am.” Hmmmph. I followed Amazons recommendations on pricing, and I guess that includes making it unavailable to all y’all non-American-types, even though I was pretty sure that the list of nations that it would be available in included the whole Anglosphere and then some. Or maybe it just takes longer to become available elsewhere. Hmmmph, I say.

Also: For USBP #02 on Amazon, I plan on tinkering with the format a bit. Nothing major, but I plan on trying to figure out why the filesize, an the imagery, got a lot smaller.

Also also: I went to Amazon and did a search on “bomber project” to see if and where USBP01 showed up. Turns out it’s right up there. Curiously, as you can see from the screenshot, USBP01 is listed as “#1 Best Seller in 30-Minute History Short Reads.” Woo! That was promising, so I spooled up the page that tells me how it’s selling, to see how many hundreds of copies it has sold to reach #1 status. Six!. Well… just “six.” Not “six hundred.” So I’m guessing that “30-minute short history reads” is a category that’s not exactly burning up the charts.

It’s in among some good company, at least. Pity about the dreary cover, I suppose.


 

The third October PDF Review has been posted over at the Aerospace Projects Review Blog. This describes wind tunnel testing of the XP-85 “Goblin”, specifically with the trapeze recovery system.

These PDF Reviews are brought to you by the APR Patreon. For as little as 75 cents per month, you can help me dig into the forgotten corners of aerospace history… and get yourself some goodies in the process. Head on over!

Many years back I was given a photocopy of a Soviet journal article describing a Soviet version of the WWII-era “Silverbird.” The Silverbird was the brainchild of Austrian rocket engineer Eugen Sanger and was a concept for a hypersonic rocket powered “spaceplane” capable of dropping bombs halfway around the world. In the years immediately after the war, the report Sanger wrote proved to be influential on policymakers and engineers, especially in the USSR.

This article describes a Silverbird modified with sizable ramjet engines mounted to the wingtips. Sadly, I can’t read a single word of Russian, so I can’t make heads or tails of it apart from the illustrations. One notation indicates that this may date from 1947. The vehicle described would seem to be the “Keldysh Bomber.”

I have scanned the article and posted it as a PDF on my Patreon for patrons at the $1.50 level (c’mon… that’s $1.50 a month! Mere pennies a day!).

I’ve uploaded a PDF file of some good diagrams of American aircraft Gatling guns to my Patreon “creations” page for all my patrons. Some years ago I made photocopies of these pages from… something. Clearly it was an Interavia publication, but I couldn’t tell you what with any certainty. A quick Google search indicates that the “Interavia Data” volume on “Aircraft Weaponry” is a good bet. if anyone knows for certain, I’d be happy to have some sort of confirmation.

The X-37B has been lurking in orbit since December, 2012 doing… whatever it was it was doing. Suspicions generally revolve around it performing recon missions of some kind. But it has returned at last to a safe runway landing. Some good photos from an just after that landing are here:

This is the second of four “PDF Reviews” I plan to have in October, to make up for the lack of any in September. The idea is to present interesting online resources for those interested in the sort of aerospace oddities that you can find in the pages of Aerospace Projects Review. This little project is supported through my Patreon campaign; at current levels, I’ll post two such reviews per month. If you’d like to see more, or just want to contribute to help me along, please consider becoming a patron.

This one is a bit different from usual. Instead of a report full of art and diagrams and charts and, well, sentences, this one has none of those. Instead, what it does have is 5,271 pages of data. Data, specifically, on the X-Y-Z positions of every single vertex of every single tile on the Shuttle. Of what value is that? Well, someone with a whole lot of patience could, I presume, feed this data into a 3D modeling program and produce a *really* accurate model of at least part of the Space Shuttle. So… knock yourself out.

Not long ago, I was alerted to a pair of eBay auctions for vintage blueprints of “Supersonic Escape Capsules.” The blueprints, produced by the US Army Air Forces, depict models of the capsules made from plexiglas and plywood. This would be generally interesting to me, but one of the diagrams seemed to indicate that the diagrams might not be what they said they were. Instead, it looked a *lot* like an aerodynamically improved “Fat Man” atom bomb. I suspected that what was for sale were actually test or display models of early atom bomb casings, intentionally mis-described for security reasons. I managed to score both blueprints with surprisingly minimal fuss.

Upon receipt of the blueprints, my suspicion that at least one of them depicts an evolved Fat Man seems to have been misplaced. Fat Man was about 60 inches in diameter; the model is 38.5 inches in diameter, which would make for an odd scale. But the idea of a supersonic escape capsule being studied in 1946 is also odd, since the USAAF was years from having supersonic aircraft. And the configurations don’t really seem to work as escape capsules; typically such things are the entire cockpit which can break away from the aircraft, but these would make for very unfortunate cockpits for supersonic aircraft. So at the current time I can’t quite figure this one out. I’ll continue to see if I can run down info on this, but leads are few.

I have not scanned in these blueprints yet. They’ve been folded up longer than most of the people reading this have been alive, so it’ll take a good long time to flatten them out and make them safe for scanning. But I’ve taken some photos, which I’ve made available in full rez in a ZIP archive for all of my APR Patreon patrons. The APR Patreon page is HERE. If you want to help preserve and make available obscure aerospace history items such as these, please consider contributing to the APR Patreon. For as little as $0.75/month, you can help out, plus gain access to a bunch of aerospace “rewards” like these. You can also help out by helping to spread the word.

The first “escape capsule” on a quite good vintage blueprint. The resemblance to “Fat Man” is obvious… but likely dubious. It’s a close match to the Davy Crockett warhead from a decade later.

One of the problems with photographing large format blueprints is the almost inevitable groupies. Cats like paper. Cats *love* crinkly paper. And 70-year-old vellum blueprints are the crinkliest of crinkly paper. Fortunately, no damage done.

I’d planned on having these done a few days ago, but as I’ve reported recently, CAD drafting has been difficult of late. Nevertheless I forged through, and here’s a preview of the next three things I plan to release.
