Thanks to ebay and my fabulously lean bank account, I have recently procured a number of items of potential interest:

“NASA Earth Orbital Space Station,” a poster-sized lithograph from McDonnell Douglas depicting a space station that tumbles for artificial-G.

“Re-Entry Payload Launch Vehicle,” A *brief* General Dynamics presentation on a vehicle to launch re-entry vehicles such as MIRV warhead shapes

“Proposed Development Program on Rocket-Type Missiles,” a 1948 Convair report on early ballistic/boost glide missile concepts, that would lead to Atlas. Includes some fantastic large format layout diagrams.

“Detail Specification for Consolidated Vultee Model 117 Airplane Class VR Transport Flying Boat,” August 1950, all the details on the then-brand new Tradewind.

“Detail Specification for Class VP Long Range Patrol Seaplane,” Consolidated Vultee 1946, all the details on a proposed flying boat patrol/bomber

32 issues of “Astronautics” magazine from 1957 to 1969, mostly 57-59 and 63 or so.

The lithograph and the reports will be scanned and put forward for consideration for monthly rewards; the magazines will have the interesting bits scanned and made available to the subscribers/patrons.

$200 a round rocketgun

Here’s something you don’t see too often… someone firing *numerous* rounds from a Gyrojet. Each of these .45 caliber rounds are solid propellant rocket units, last manufactured in the 70’s or so. They apparently run about $200 *each,* which makes me wonder if there might be a market for newly manufactured ammo. As a practical home defense, police or military weapon… the Gyrojet basically wasn’t. It took something like 50 feet for the round to reach maximum velocity, which means at close range it might just bounce off an opponent. But as a range toy they might be fun, especially if the cost per round could be dropped substantially. And there’s no reason why it can’t… sure, each round is more complex than an equivalent conventional bullet, but they are just some basic parts with 1960’s rocket propellant. And that last could doubtless be improved; better propellant, better grain design and better manufacturing of the nozzle plate could *really* boost performance.

The claim is made here that the Gyrojet was designed to be used in space because they were uncertain if conventional gunpowder firearms would work in a vacuum. This is untrue; nobody with the least bit of understanding of the chemistry of gunpowder and how guns work thinks that guns *won’t* work in space. However, conventional firearms do have three major issues for space applications:

Recoil.
Thermal issues: exposure to sunlight and vacuum means that small metal devices like guns heat up *fast.*
Vacuum issues: grease, gun oil and the like boil off quick, meaning they can’t be used in space.

The Gyrojet has far lower recoil than conventional firearms. And the Gyrojet is a far simpler mechanism, made largely from stamped metal sheet to far lower specifications. This means it can heat up without jamming, with virtually no need for lubricants. So the Gyrojet seems like it’d make a dandy sidearm for the USSF. Bump it up to .75 caliber and you have yourself a light bolter. And perhaps best: home manufacture of Gyrojets would be *easy.* A 3D printed Gyrojet, with some *basic* metal parts, would not only be easy to make, but with vastly lower forces imparted on it than a conventional firearm, it’d be far less likely to explode.

So… where are the new-manufacture Gyrojet rounds? At $200 a round for the vintage stuff, you can start off *real* expensive and still undercut the current market.

KSC Master Plan

Recently acquired at some cost, and finally fully scanned at some effort, is this 1965 “Master Plan” for Kennedy Space Center. It’s basically a book of maps of the region showing all aspect of the infrastructure. It’s in good shape and was scanned at 600 DPI rather than the usual 300, due to the fine quality of the maps. It will be in the next catalog for Patrons and Subscribers to vote on. It’s a little out of the usual for APR… it’s not about unbuilt aircraft or spacecraft; in fact, no aircraft or spacecraft designs are included. But it’s still an interesting historical artifact.

I also have a KSC Master Plan from the Shuttle era. Substantially larger format, with more conventional full-color maps. I haven’t scanned that due to the chore it would be to get done, but if this proves popular, I’ll get on it. I *also* have a large-format Master Plan for Ames Research Center.

New PBYs?

Color me not just skeptical, but damn near dismissive:

Reviving The PBY Catalina For Modern Warfare Is This Company’s Goal

I fully support the manufacture of newly designed, modernized PBY “Catalina” flying boats. Damned things were awesome 80 years ago; had I buckets of money, I’d fund the program myself. But *this* program does not inspire a great deal of (i.e “any”) confidence. All they show are a few *very* low re and simplistic CG renders of a modernized PBY… lacking the braces that kept the parasol wing from snapping off during maneuvers. I know materials have advanced a lot since the 1930’s, but come *on,* that design just don’t look right without those braces.

Recall that just over a year ago an Australian company said they were going to remanufacture the Grumman Albatross flying boat. The last “news” update to their website was December of 2022.

Bell D188A Art

A cutaway illustration of the Bell D188A VTOL strike-fighter from the late 50’s/early 60’s. This Mach 2 aircraft would have used 8 small turbojets… two lift/cruise in the tail, two vertically mounted in the forward fuselage for lift and two each in wingtip nacelles that could tilt for VTOL or horizontal thrust. Often referred to as the XF-109, it was only called that in Bell PR material.. it never officially received that designation. The artwork below was scanned years ago at the Jay Miller archives.

There is more available on the D188A in two sources I highly recommend (because I wrote them):

1: Aerospace Projects Review issue V2N4. Jam-packed with info, diagrams, artwork of this and several variants.

2: US Supersonic Bomber Projects Vol. 2, which uses the D188A as the cover image.

If you’d like the full resolution version of the cutaway artwork, it has been uploaded to the 2023-07 APR Extras Dropbox folder, available to all $4 and up Patrons/Subscribers. If you would like to help fund the acquisition and preservation of such things, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program.

Ryan X-13-like Tailsitter Interceptor

fighter No Responses »

Jul 032023

Ryan released this piece of art in 1958 depicting a tailsitter fighter somewhat like their X-13. However, this was clearly a much larger vehicle, operational rather than experimental. More than anything it resembles a slimmed-down and stretched-out Avro Arrow. It’s unclear that this was based on an actual engineering study, rather than artistic license.

This would seem to be an interceptor, presumably installed somewhere in Europe within hidden underground bunkers. It’s not at all certain to me that in the event of all out war there’d be any real point in having these aircraft be able to land vertically as their bunkers would probably be radioactive glass by they time they got home… and without the dedicated equipment needed to catch the aircraft, they’d be unable to land.

The X-57 won’t fly

A NASA article on the status of the X-57 “Maxwell” says that they’re wrapping up work on it, with no mention of it actually flying:

X-57 Project Creates Paths Toward Electric Aviation

The X-57 is a modification of an existing conventional aircraft to be all-electric. Lots of new technologies were integrated and apparently some useful advances were made, but the real issue remains batteries. Until the energy density of batteries gets a *lot* better, electric-powered aircraft are going to remain pretty niche. Flying the X-57 would be nice, but with the existing batteries it’s kind of dead in the water.

What would be great is if NASA kept working on the X-57 at a low level. The technologies onboard would be occasionally upgraded, and when meaningfully better batteries – or perhaps some sort of modular fuel cell system, perhaps, or indeed a small nuclear reactor (a man can dream) – become available, integrate them into the vehicle and at last fly it.

“XB-2002 Stealthawk”

Jun 272023

This popped up on ebay a few years ago. It purported to be a Boeing design for an advanced subsonic stealth bomber… but the design is, clearly, rather silly. Supposedly it dates from 1984 and was produced at, by and for Boeing, intended to be a decoy for the B-2 Advanced Technology (Stealth) Bomber competitors. I’m not sure Lockheed or Northrop would have looked at this and seen a serious design, however.

*Some* aspects of it seem like they might have been taken from an actual stealthy bomber design… the inlets and exhaust, indeed much of the middle part of the wing/body, look about right. But to stubby wing and especially the straight-vertical fins in substantial numbers are goofy aerodynamics and spectacular corner reflectors.

At least two of these were made and wandered out into the wild over the years.
