In 1985, Rockwell ponders the business case for solar sails. Solar Sails, or “light sails,” had been around for a couple decades at that point, though purely as hypothetical constructs. Solar sails would really only be useful for interplanetary transits, which would of course limit the number of potential customers.
Below is an image taken from a history of the B-52, artwork depicting the YB-52 configuration packing a single Navaho cruise missile. Cool and all, but there’s something bugging me: I could *swear* that a year or three back I came upon or was sent a passel of images showing, among other things, the B-52 carrying Navaho missiles, in the form of both artwork like this *and* diagrams. But I have been unable to locate these images, whether due to them getting separated during the move, or misplaced/misfiled prior to the move… or them not having existed in the first place because my brain is having a little joke at my expense. Unfortunately my tiny little brain is incapable of letting go of missing things like this and it’s driving me buggo. Does this sound at all familiar to anyone?
In 1985, Rockwell International considered the business case of an advanced single stage to orbit vehicle. The design illustrated was a manned, winged horizontal launched, horizontal landing design with, oddly, air inlets on the upper surface. Unlike the “Orient Express” or NASP designs of the time, this design was not meant to lift off and accelerate to Ludicrous Speed using scramjets, but was to lift off and rather sedately rendezvous with a tanker aircraft. This… is a bit familiar.
In the late 1990’s I worked for Pioneer Rocketplane. Our plan was to design and build a spaceplane that would lift off from a runway under turbojet power, with fuel tanks full of RP-1 and oxidizer tanks full of very little. The vehicle would rendezvous with a tanker aircraft which would transfer not jet fuel, but liquid oxygen. This is because for best performance an RP-1/LOX rocket system needs a far greater mass of LOX than RP-1. So leaving the LOX tank basically empty (a small amount was carried to keep the tank pressurized and chilled) would allow the vehicle to lift off at lowest practical mass. This lowered the mass needed for the landing gear, and lowered the surface area needed for the wings, which of course lowered the mass of the wings. The rocketplane would tank up, separate from the tanker and fire its rocket engine. In the case of the Pioneer Rocketplane “Pathfinder,” the spaceplane would reach orbital altitude, but not orbital velocity. An upper stage would boot the payload into orbit; the spaceplane would return home, either gliding or under jet power. The Rockwell design illustrated below *seems* to have been meant to operate in a similar fashion, but with the spaceplane intended to put itself directly into orbit. Most likely it would have been LH2/LOX powered, probably with SSME derivative engines.
The description in the text, though, describes very different vehicles, using propulsion system best described as highly steeped in the hypothetical. Atomic hydrogen and metastable helium are great stuff if you can get them… and, basically, you can’t. Not with 1980’s tech, not with 2020 tech. Someday, maybe.
In 1985, Rockwell International contemplated the business case for Shuttle Derived Launch Vehicles. The specific design illustrated used the ET and SRB’s more or less stock, but the orbiter was replaced with a recoverable propulsion and avionics module. The payload came in the form of an upper stage with something very like the Apollo Command and Service Modules. This would probably have been for a lunar mission of some kind as a Shuttle-class booster is too big for a simple capsule mission to LEO. The basic design would have roughly performed like the presumably forthcoming SLS.
The USAF’s reference design for an operational space based laser missile defense platform, circa 1990. Details such as mass and dimensions remain elusive, although the fact that it was to be launched by a “Titan V” might be instructive.
Point the first: it’ll be a bit lax on the blogging for the next little while. Got stuff to handle. Not, not coronavirus… not yet, anyway.
Point the second: color me stunned, Boeing done failed another aerospace project.
In 1985 Rockwell thought that there might be a business case for a small unmanned spaceplane for recon purposes. At the time, the answer was apparently no… but within a few years Rockwell developed the “REFLY” spaceplane which, over a span of a couple decades, transmorgified into the X-37B which has flown a handful of top secret long duration missions.
A piece of Lockheed concept art circa 1966 depicting a concept for a stowed-rotor helicopter, capable of efficient hovering performance as well as efficient high speed forward flight. This design is related to though distinct from the design depicted in artwork HERE. Note that the backgrounds of the two paintings share a lot of similarities… same ground structures, same leaves in the lower right. I don’t know if this means that one painting was copied from the other, or if one painting was painted *over* the other. In which case… as noted on the other post, I actually own that other piece of artwork. Buried under that upper layer of paint might be *this* image. Ain’t no way I’m going to scrape the paint off just to check, but the technology exists to X-Ray it to look for what’s buried underneath. Not that I’m going to do *that* either…
This aircraft is shown operating in Viet Nam, in US Army colors. This would have irritated the hell out of the US Air Force; by 1966, the USAF was to have control of all fixed wing combat aircraft. The role for this aircraft in Viet Nam would have been search and rescue rather than the transport of troops or ground attack, but still the USAF would have objected.
This piece of art came from a magazine article published in 1966.

In the 1980’s, military spaceplanes were all the rage… at least on paper. In 1985 Rockwell International considered the possibility that there would be a profitable business case for a relatively small manned spaceplane that could serve as a rapid-reaction launch system for missions such as recon. Thirty years later the X-37 finally accomplished something sorta along those lines, though without the crew and rapid reaction.
A little while back I was contacted by someone who had an old display model of a Boeing Controlled Configured Vehicle bomber and wondered if I was interested in buying it. Interested? Yes. Able? No. But I was able to put the seller in contact with someone else who was able to procure it, so this Boeing CCV-100-2 wound up in a good home. More on the CCV-100-2 is HERE. Still no confirmation of the scale of the vehicle, sadly.
