The USSF wants to actually be able to do their job. Could we see the return of the heady days of the Star Wars program? Now that we have actual almost-affordable and mostly-reusable space launch, we just might. Get ready for the pages of Aviation Week to be filled with artists concepts of space based lasers, neutral particle beams, orbital and cisluanr assets of all kinds. Can we even dream of manned nuclear powered spacecraft patrolling the spacelanes?

 

Of course, a lot will depend on November.

So after having the 3D printer for a while and running a *lot* of resin through it, I have achieved some good things. I’ve learned enough to know that there are some things that I plan on producing as full 3D-printed kits, some to be converted into metal castings. I have a few product lines that I want to do:

1: 1/285 (wargaming scale) “minis” of a range of appropriately sized unusual, rare, interesting and projected aircraft/spacecraft

2: “Mini”-sized, but of various scale, aircraft and spacecraft to go with each issue of US Aerospace Projects

3: 1/18 scale models of each American nuclear bomb/warhead/re-entry vehicle. This will range from the downright dinky to the “I’m not sure how to squeeze this out of the printer,” like the Mk 17 and the Flashback. I’ve successfully printed prototypes of the Fat Man and Little Boy A-bombs in 1/18, but they need to be revised.

4: Just whatever strikes my fancy by way of interesting aerospace/sci-fi concepts.

The eventual 3D printed kits will be pricier than if they were cast resin “garage” kits, but this will allow me to make them on demand. I hope there is interest in this sort of thing. To that end, and to help refill my depleted coffers, I’m making available a “crowdfunding” project with three levels. What you will receive are the actual 3D printed components. Each level builds on the prior… Level 2 gets you the Level 1 stuff, Level 3 gets you 1 and 2. No additional postage is required for continental US address… Hawaii, Alaska, Canada, the rest of the world, contact me and I’ll work out the additional postage cost.

Note: many of these are “prototype” kits, with revisions and improvements possible or even probable. And some of these are not planned to be released further. This will be your only chance to get them, at least in this format.

Level 1. You will receive:

1/285 X-20 Dyna Soar spaceplane
1/285 XF-103 Mach 3 interceptor
1/285 Project Pluto nuclear ramjet
1/285 X-15 set (X-15, X-15A2, X-15A3, X-15/SERJ)
1/18 Davy Crockett battlefield atomic warhead w/stand

Crowdfund level 1: $60 in the continental US:

——–


Level 2. You will receive:

1/18 US Atomic Artillery Shells w/stand
1/144 X-20 Dyna Soar
1/18 M61 Vulcan Gatling Gun w/stand
1/18 Mk 72 Nuclear Warhead/Re-Entry Vehicle

 

Crowdfund level 2: $100 in the continental US:

——–


Level 3. This part will not ship immediately, as some of it remains unfinished. You will receive:

1/285 XF-103 w/missiles
1/350 Orion Nuclear Pulse Vehicle (with stand… not yet finalized)
1/2000 Aldebaran Concept Vehicle
Cast Metal 1/285 X-20 + XF-103 + X-15 + Pluto: Depending on the success of the casting process. Not all are guaranteed.

 

Crowdfund level 3: $200 in the continental US:

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.

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.

In 1983 “Science Digest” ran an article that 13-year-old me lost his tiny little mind over. Illustrated by Rick Sternbach, designer of, among other Star Trek vehicles and artifacts, the USS Voyager, it described a series of possible means of interstellar travel. While the physics and engineering of some of them have proven dodgy in the years since (the Bussard ramjet has serious problems with the proposed magnetic fiend, the Enzmann starship has turned out to not be as well thought out as many had assumed, etc.), it remains a tantalizing glimpse of what might be. The article has been scanned in full color and made available to APR Patrons/subscribers at the above-$10 level.

 

If you would like to help fund the acquisition and preservation of such things, along with getting high quality scans for yourself, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program. Back issues are available for purchase by patrons and subscribers.

An interesting CGI video depicting three sizes of folding rotor tiltrotor High Speed VTOL from Bell. The concept is not new; actually building and flying one, though, would be. The designs shown are also not new; Bell has been floating them for a few years at least since late 2021.

Atlas launch to test inflatable heat shield

 

A United Launch Alliance Atlas 5 is scheduled to lift off from Vandenberg Space Force Base in California at 4:25 a.m. Eastern Nov. 10. The primary payload of the rocket is the Joint Polar Satellite System (JPSS) 2 weather satellite …

A secondary payload on the launch of JPSS-2 is Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID), a NASA technology demonstration. While JPSS-2 will be deployed nearly a half-hour after liftoff, LOFTID will remain attached to the Centaur until 75 minutes after liftoff, following a deorbit burn of the Centaur.

Shortly before deployment, LOFTID will inflate a reentry shield six meters in diameter. That heat shield will slow down the vehicle from orbital velocity to Mach 0.7 as instruments on board collect data on the performance of the shield. LOFTID will then deploy parachutes to slow it down for the rest of its descent, splashing down in the Pacific east of Hawaii to be recovered by a ship.

Inflatable heat shields have been studied since before humans flew into space. Normal heat shields need to withstand insanely high temperatures, requiring materials that are either insanely expensive and complex, or that involve complex, fragile and heavy active cooling systems (such as water cooling through transpiration), or which are ablative. The latter variety is technologically fairly simple, but ablatives tend to be heavy and they are labor intensive to apply and make reusability difficult.

With temperatures reaching several thousand degrees, inflatable materials would seem inappropriate for heat shields. But those high temperatures are not a mandatory feature of re-entry. To a first hand-wave approximation, the maximum temperature is proportional to the mass-per-surface-area of the re-entry vehicle. A one-ton vehicle is going to have to shed all of its orbital velocity, converting all that kinetic energy into thermal, regardless of the size or shape or cross-sectional area. The way that is done is by compressing the air the vehicle slams into; the heating isn’t due to friction, but to the compression of the gas. If you can spread that heating energy out wider… the gas doesn’t heat up as much per unit surface area. Heating can be reduced from the sort of thing that will melt tungsten to the sort of thing that can be survived by advanced polymer fibers. As a bonus, the inflatable shield, being far larger than the solid shield on the vehicle, provides drag all the way down. In principle it would be possible to dispense with parachutes, wings, retro-rockets, and simply drift down using the shield as an inverted parachute. This was the case for the Douglas “PARACONE” concept from the mid-1960s, designed for, among other uses, as an emergency “life boat” for astronauts in space. It would provide for a safe entry, deceleration and touchdown on either land or water.
