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than 10X the linear dimensions than the version above) and has been made available as a thank-you to APR Patreon and Historical Documents Program patrons at the above-$10-per-month level. If interested in this piece 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preservation of this sort of thing, please consider becoming a patron, either through the APR Patreon or the Monthly Historical Document Program.

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preservation of this sort of thing, please consider becoming a patron, either through the APR Patreon or the Monthly Historical Document Program.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.
