Here are some hypothetical subjects for metal casting as “minis.” I have three pages (standard 8.5X11) of diagrams, all depicting possible subjects at the size they would be at the stated scales. First page shows what I consider a number of interesting designs… not at a constant scale, but size.

 

 

 

Second page depicts a range of Project Orion vehicles again at a roughly constant size. Constant size means, hopefully, a consistent cost.

 

Third page shows two sets of 8. The US Bomber Projects #1 set has 8 bombers at roughly constant size; US Fighter Projects #1 set has the fighters all at the same scale. 1/285 at least used to be a kind of standard for wargaming, though I’m not sure how widespread it truly was.

 

Sets like USBP01 would probably all be at about the same price, but those like USFP01 might vary since some designs at quite a bit bigger. What I’m kinda hoping for is the individual minis being about $25 each, while the 8-sets be about $100 each. Thoughts?

 

These are of course not the full possible catalog, nor would all these here necessarily come to pass. And scales/sizes could vary substantially. A lot of it would depend on actually trying them and see what works, what fails spectacularly.

Bell-Boeing LHX Tiltrotor art

Artwork circa 1983 depicting a one-man combat tiltrotor tearing up a column of Soviet armor. At this time the Light Helicopter – eXperimental program included the possibility of tiltrotors as well as conventional choppers. In the end the RAH-66 won… and was then cancelled before series production. Tiltrotors showed promise, but also promised to be incredibly challenging for a single pilot to manage.

Rockwell Space Station: 1982

Published in a magazine in 1983, this artist depiction shows a concept for a 1982 space station by Rockwell. Clearly of the same *kind* of station as the eventual ISS, this is a simpler, smaller construct. However, it also includes a “cargo bay” modeled aft that of the Space Shuttle, allowing payloads (what appear to be temporary science modules) to be readily transferred back and forth.

But not on ebay yet. If any of these are of interest, let me know.

First Lunar Outpost artwork

In 1992 NASA had a flurry of PR about the “First Lunar Outpost” concept which would see the US return to the moon using large lunar landers launched by a single Saturn V derived heavy lifter. A fair deal of concept art was released; much of it used the relatively new technology of computer generated imagery. Five of these images recently appeared on ebay as 16X20 prints; what the heck, I went ahead and bought them. They arrived today and I was pleasantly surprised at the production quality. They weren’t simply printouts glued to cheap foamcore, but instead are very glossy, hard plastic bonded to higher quality foamcore.

I believe I’ll have these professionally scanned and made available to APR Patrons/subscribers.

Dual-fuselage DC-9

NASA artwork (probably 1970s/early 80’s) of a dual-fuselage DC-9. This would double the capacity while not doubling the weight; drag would go up, but so would aerodynamic efficiency due to increased effective aspect ratio of the wing, as well as being more structurally sound for the weight. The need for a pretty wide runway is something of a concept-killer, though.

Orion Space Battleship

With all the little publications I’ve written and illustrated, and all the years of blogging ABSOLUTELY BRILLIANT political opinions and the like, it seems that at least *one* of my efforts will go down through the ages: my design for the Orion Battleship. We know to a fair certainty that such a craft was designed in the early 1960s, and that a mockup the size of a car was built; we know some of the components and features of that design. But other than that… we don’t know much. The overall size and configuration are unknown. So, fifteen years ago when I was working on an article for Aerospace Projects Review about large Orion vehicles, I went ahead and made a speculative reconstruction design. I did my best with what was available… and in the years since, nothing seems to have come out to refute the design. I do not contend that the design is an accurate reconstruction; I was never able to get in touch with anyone who knew the Battleship design first-hand to confirm my reconstruction. I could well be *badly* wrong, especially since the descriptions of the original design tend to be second-hand. One day we might find out for sure.

But in the years since I showed my design to the world, I’ve seen it recreated here and there. It seems to be the accepted Actual Design.

Huh.

Behold:

That second video uses a model based on my design, more renders of which are HERE.

My renders – unimpressive even by 2009 standards – even made it into meme format:

B-1A concept art

Black and white concept art, Rockwell illustration from the early 70’s represents the almost-final B-1A configuration, from back when being very supersonic was the goal rather than being stealthy at low altitude. Most obvious differences between this and the as-built B-1A are the ride control vanes (the small canards) and the discontinuity in sweepback angle between fixed and movable portions.

Fairchild M-232

A late 1950’s project from Fairchild Aircraft for a STOL aircraft, the M-232. The propulsion system was fixed, but the wings were given large flaps that would direct the bulk of the propwash more or less downwards. Coupled with the extreme nose-up attitude on the landing gear, this would almost be enough for vertical takeoff and landing. An aircraft like this would be used in a role much like that of the OV-10 Bronco.

This came from a series of articles that have been scanned and made available as “Extras” to APR Patrons and subscribers at the $11 and up level. 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.

Forced deflection nozzles for ICBMs

There are several ways to accomplish the goal of extracting maximum performance from a solid rocket motor via the nozzle. The most common way – a convergent-divergent nozzle – is the standard for a reason: it’s the simplest, lightest most reliable way to do it. But there are alternatives that provide specific advantages. One of them is the “forced deflection nozzle.” Instead of a single circular throat, the nozzle has several; instead of directing the exhaust gas due aft, it forces it “sideways” to smack into the broader, shallower nozzle.

The advantages here:

1: The nozzle is sort of a hemispherical bowl, rather than a long, slim cone or paraboloid.

2: It provides some altitude compensation, similar to an aerospike.

There are also disadvantages, not least of which is that the throat is now under substantially greater thermal and dynamic forces. Few materials known to Man will be able to long withstand the high heat load and erosive forces. But in 1986, Aerojet proposed to develop such a nozzle for a singular purpose: to integrate into future ICBMs. The reasoning was… the bowl-like nozzle fits the bowl-like forward dome of the lower stage. Instead of a long interstage structure being required, the stages fit together neatly. in principle this would allow ballistic missiles to be more compact, shorter by useful distances. This is not very important for space launchers, but for missiles that need to fit into silos, submarines, bomb bays or Shuttle cargo bays, extra space means extra capacity.

 

 

Diagram showing a conventional 3-stage solid rocket ICBM against three concepts making use of the forced deflection nozzle. You could have a much shorter vehicle with equivalent weight and payload, or same-length boosters with 28.4% greater range for the same payload, or 33% greater payload for the same range.
