Possibilities of New Business Growth: Space Construction Facilities

Jan 052020

In 1985, Rockwell considered that there might be a market for space construction facilities for large orbital structure such as solar power satellites, large radio/radar antenna, SDI “elements” (likely references the relatively gigantic neutral particle beams, space based lasers and other “space guns” that were contemplated at the time) and other large structures. This capability was first contemplated in the mid 70’s for the SPS program, but did not really last much past the late 80’s when such vast structures were no longer really expected anytime soon.

B-1 Artwork: not the view you really want of a supersonic aircraft

Certainly a dramatic shot, and also a very final shot for a bug, bird or unfortunate parachutist.

This Rockwell illustration dates from the early 70’s and represents the almost-final B-1 configuration, from back when being very supersonic was the goal rather than being stealthy at low altitude.

Lockheed Composite Aircraft Art

Some years ago I scored some aerospace concept art off ebay. This is not an unusual occurrence; I’ve procured a great many lithographs there. But this one was different… it was the *actual* original painting created in the mid-60’s. At the time I couldn’t really get a good scan of it, but a change in scanners a while back, coupled with the recent move and revival of the “scan everything” project allowed me to finally digitize the thing.

The image depicted a composite aircraft that used stowable rotors for VTOL and hover like a helicopter, and turbofan engines for efficient fast forward speed. As shown here it is operating in Viet Nam in a combat search and rescue role, something the Lockheed CL-945 (a very similar design) was intended for.

The full image is far bigger (a bit bigger than 10X the linear dimensions than the version above) and has been made available as a thank-you to APR Patreon and Historical Documents Program patrons at the above-$10-per-month level.

Large format scanning in progress

As hinted at here and there, I’ve recently moved from rural Utah to non-rural elsewhere. One of the benefits of the move was that it put me a LOT closer to large format scanning services. Previously getting a large blueprint scanned meant several hours on the road and then a return several days later to pick it up; now the drive is a matter of a few minutes. Consequently, my rather extensive backlog of large format aerospace art and diagrams is finally getting scanned in bulk.

Behold some recent results, mostly involving early Titan III, Saturn and Dyna Soar studies:

Some of these will end up in the monthly “catalogs” for the APR patrons to vote on… and some will end up as “extras” for patrons, particularly for above $10-level patrons. If these sort of images are of interest, or if you are interested in helping to fund the preservation of this sort of thing, please consider becoming a patron, either through the APR Patreon or the Monthly Historical Document Program.

Additionally: if you have large format diagrams that you feel are of aerospace historical interest, let me know. I’m always in the market to buy, rent, borrow such things.

Possibilities of New Business Growth: Nuclear/Microwave Space Power Systems

By 1985, the Solar Power Satellite was essentially dead, killed off by the plumetting price of oil. But the technology developed for it was still valid, and Rockwell thought there might be a use for microwave power transmission systems. Their idea here was to use a space-based nuclear reactor – apparently something along the lines of the SP-100 – to generate electricity and then use SPS-derived microwave beaming tech to send that power to distant “customers” such as space stations and satellites. This would permit the customers to basically have nuclear power, but without the risks of having a nearby radiation source. The receiver would be much lighter than a PV array in terms of construction, and vastly more efficient, since all the energy coming in is of a single fixed frequency. A space station could presumably have a power receiver in the form of a mesh “net,” perhaps a single sphere a few meters in diameter at the end of a modest mast, capable of capturing dozens to hundreds of kilowatts of clean electrical power. This would lower the cost and mass of power systems compared to PV arrays… and it would greatly reduce the drag produced by those giant sails.

Rockwell suggested in 1985 that manned versions of their ballistic cargo return systems could be used to return astronauts from the space station in the event of an on-orbit disaster. Two concepts are illustrated (“ENCAP” and “SAVER”), one similar to the Douglas “Paracone” from the 1960’s, and a version using a balloon to provide drag. So presumably the cargo return system, illustrated with a lifting body diagram, would actually closely resemble one of these systems.

Spaceballs

A 1978 NASA artists impression (taken from ebay) depicting a “rescue ball” being used. This short-lived product was basically a space suit in spherical form, one that a Shuttle astronaut in shirt sleeves could enter relatively quickly in the event of an on-orbit disaster. Another Shuttle could send astronauts to collect the encapsulated and helpless astronauts and transfer them to a non-doomed shuttle. It was *kind* of a good idea, but once it was realized that the Shuttle takes *weeks* to prep for launch, the idea of using a Shuttle to rescue another Shuttle fell by the wayside. Instead of the crew of a stricken Shuttle relying on another Shuttle for rescue, official policy became la-la-la-I-can’t-hear-you and orbital rescue equipment became superfluous.

“Passenger Carrying Space Shuttle”

Here’s an article from “Future Life” magazine, May 1979, describing a Rockwell concept for a passenger module for the Shuttle. This could carry 74 passengers, a loadout that seems perhaps excessive until you realize that it was meant to transport the crews who would build the miles-long solar power satellites. If this concept is of interest, be sure to check out US Bomber Projects #06, the Solar Power Satellite Launch Special. There, another concept for a Shuttle “bus” was described and illustrated.

Possibilities of New Business Growth: Cargo Return From Orbit

In 1985, Rockwell considered the possibility of making a business of returning commercial cargoes from orbit. This is a tricky proposition: almost *nothing* in space is worth more returned back to the ground. Humans, of course, and highly hypothetical products made in zero-g… drugs, crystals, electronics. but none of those actually panned out: zero-g and/or high vacuum might produce some small benefit for various chemical processes, but terrestrial manufacture is so much easier and cheaper that nothing has so far come from on-orbit production

The description mentions a “ballistic cargo carrier,” but the piece is illustrated with a lifting body. This appears to be the same vehicle mentioned previously as a “hypervelocity research vehicle.” I don’t know if this means Rockwell gave thought to using the HRV as a cargo return system (if so, it would be an inefficient way to go) or if the HRV diagram was simply conveniently at hand. A ballistic capsule would probably be by far the best way to go for returning payloads that are relatively insensitive to g-forces. Cheaper, smaller, lighter and, importantly, cheaper than a lifting body.

Possibilities of New Business Growth: Telepresence Facilities

Nov 202019

In 1985, Rockwell wondered about whether there was a business case for space-based telepresence. At the time, the technology was relatively new, clunky, primitive; today it would be vastly superior and would only hardly ever attain self awareness and decide to overthrow its human masters. But nearly 40 years ago, the systems would doubtless have been slow, unwieldy and difficult to use effectively and reliably.

Up next: a spaceplane for cargo return! Stay tuned! Tell your friends! Invest now! The APR Monthly Historical Documents Program helps keep this sort of thing coming.
