A recent series of patents has received some press, where some people suspect that this VTOL aircraft concept is a “flying car” from Google. The company is “Zee.Aero,” the inventor is Ilan Kroo, aeronautics professor on leave from Stanford.

The design features a multitude of small vertical lift fans and two forward thrust props. The vertical lift fans are each provided with an electric motor. The power would seem to be provided by a gas motor/electric hybrid system.

The system would seem to be fairly draggy, so it’s probably not intended for high speed. One of the patent illustrations shows one parked with folded wings in a conventional parking lot between two automobiles, indicating that there is some thinking that the inventors want this to be used as a “flying car,” It really doesn’t look roadable, so you’d have to land it at the destination. I shudder to imagine what would happen to one of these if left in a packed Wal Mart or Best Buy lot on Black Friday…

The complete rework of APR from the original release a decade ago is going a lot slower than I’d planned. A lot of people have asked for the original versions of the as-yet-unreleased issues of APR to be made available. I’ve been hesitant to do so, but… it’s just taking too long. So, I’ve taken the original Word files for the six issues of Volume 4 and the six issues of Volume 5, and made two PDF files from them. I’m making them temporarily available as two bulk sets. When the issues are re-released, these full-volume sets will be withdrawn. So, Volume 5 might remain available till the sun explodes, I dunno…

If you’re dying to get hold of the old-school APRs, here’s your chance. Remember, these are the *original* files from around 2002-2004, without any updates, edits or other changes. Errors, crappy formatting and all. A bunch of the individual old articles remain available as well.

A decade ago I released Aerospace Projects Review solely in printed form… in the form of simple 11X17 sheets stapled down the centerline. In recent years I’ve released it – and other aerospace documents – instead in PDF format, and also as a high-quality print-on-demand version. While the PDF versions are quick and cost effective, they don’t fit on a bookshelf. The Magcloud versions are good, but a bit limiting… one page size. No foldouts.

And one common feature of both PDF and MagCloud: They’re very “modern.” Most of the time, that’s just fine. But sometimes… old-school just seems a whole lot more appropriate.

I’ve picked up some old-fashioned report covers that use the folding metal prongs, the type that used to be pretty ubiquitous in aerospace offices. A generation and more ago, if you wanted to put out a report, or just bind together a bunch of stuff, this is what you’d use. In recent years, of course, these binders have fallen out of fashion, replaced with spiral bindings, 3-ring binders, or just plain scanned PDF documents and the like. It’s been a number of years since I’ve seen these things in the wild, either in office supply stores or in use. But they *scream* “this is how it’s done, son.” I’ve used large format versions of these on the recent X-20 Dyna Soar diagram set I out on eBay.

I’ve got the harebrained notion of making available a number of old reports, and things like Aerospace Projects Review, in this format. This is a lot of work (for me) compared to the PDF/print-on-demand options, but the end result is quite a bit different from the others. As a first test, I’ve re-worked the first four US Bomber Project issues into one publication, with the diagrams reformatted and rescaled for 11X17 foldouts. Here are photos of the first test :

Dsc_1010 Dsc_1009 Dsc_1007 Dsc_1006 Dsc_1008

If people are interested, I’ve already pulled out a fat stack of reports to release in this format (a number of Saturn program reports, aircraft pilots manuals, design studies, rocket engine manuals, etc.). Price would be variable, based on length, but they’d be less than a print-on-demand version, as well as including foldouts where appropriate. So, the question is… how much interest is there?

There is a bit more formatting needed for the US Bomber Projects version, obviously. Anyone want this prototype? Call it $20 plus postage.

Might come a time when I embark on true Aerospace Hispter Art Overload: using these binders to put together collections of cyanotype blueprints on vellum… that would be awesome.

United Tech produced some spiffy propaganda/PR back in the day. One thing I have is a surprisingly large book on the UA-1205/1207 solid rocket motor, used on the Titan IIIC. At the back of it is some very 1960’s artwork of proposed uses of the solid motors on variants of the Saturn I and Saturn V.

Selling this on eBay:

X-20 Dyna Soar Model 2050E diagram booklet

Here is a collection of 11X17 CAD diagrams of the X-20 Dyna Soar, specifically the final design, Model 2050E from 1963. These diagrams were created for issue V3N4 of Aerospace Projects Review; since this issue has not yet been published (and won’t be for a while yet), these will be the only copies of these diagrams out-and-about for some time. And if I get mashed by a Mack truck before V3N4… well, these will be the only copies out there, period.

These are bound in a 12X18 pressboard report cover with prong fasteners… outdated today, but appropriate for early 1960’s aerospace history. The collection currently has 25 pages, though this may change. Any additional diagrams that are finished prior to the end of the auction (I’d estimate one or two) will be added. The collection includes, but is not limited to: 1/48 scale 5-view diagram of the X-20 Dyna Soar, accurately showing the configuration of the metallic heat shields; several 1/72 layout diagrams of the X-20 with adapter and transstage; several 1/125 scale diagrams of the X-20/Titan IIIc launch vehicle, in different configurations; 1/175 X-20/Saturn C-1; 1/48 3-view of the “synergetic” configuration; numerous diagrams of various small space stations designed with operational Dyna Soar shuttle vehicles in mind; a scale comparison of the Dyna Soar with the ASSET test vehicle, the X-37B spaceplane and the HTV-2 test vehicle; separate 3-views of those other vehicles; and as a bonus, diagrams from issues V2N5 and V3N3 showing earlier versions of the Dyna Soar used as components of advanced launch systems such as the Aerospace Plane and the B-70 based Reusable Booster System.
