In 1969, Maxime Faget of NASA-Manned Spacecraft Center (later renamed Johnson Space Center) produced a concept for a simplified version of the Space Shuttles then being designed. The idea at the time was that the Shuttle would be a two-stage vehicle, both being fully reusable manned flyback vehicles. The Orbiter would be much larger than the Orbiter that actually got built because it included substantial hydrogen/oxygen tankage. The boosters were generally *vast* vehicles larger than the C-5 Galaxy meant to fly higher and faster than the X-15. Optimistic to be sure. Faget’s “DC-3” design had the same basic architecture but attempted to produce a smaller, cheaper, less complex and more realistic design. The design, produced in-house at NASA, was picked up by both North American and McDonnell Douglas, who designed their own variations on the theme.

Here is the basic configuration of the NASA-MSC “DC-3:”

A photo montage of Boeing display models showing a range of launch vehicles intended to put the early (1959) Dyna Soar into orbit. The three at left are clusters of Minuteman ICBM boosters; the next two are larger solid rocket motor clusters. The next is a Saturn I booster, followed by an all-new recoverable liquid rocket booster, the Titan II and the Atlas/Centaur. The Titan II design was chosen, though it could not actually get the Dyna Soar into a true orbit. To do that, solid rocket boosters needed to be strapped to the sides of the Titan II… leading to the creation of the Titan III.

I’m terrible at posting updates on the latest rewards, but I do get every rewards package out on time. That said, APR Patrons and Monthly Historical Documents Program subscribers have just been sent the rewards for April, 202. This package includes:

1) “Flying Carpet Feasibility Study Submarine Carrier,” a full scan of the 1958 Boeing report on a series of submarines design to carrying Mach3+ VTOL strike fighters

2) “F10F Descriptive Data,” a full scan of a 1953 Lockheed document describing this competitors design

3) Diagram 35-17610, B-52 airdrop carrier aircraft for the Model 844-2050 X-20 Dyna Soar

4) A CAD diagram of a two-stage Rockwell Trans Atmospheric Vehicle using a ground effect machine first stage

If this sort of thing is of interest and you’d like to get in on it and make sure you don’t miss any of the forthcoming releases, sign up either for the APR Patreon or the APR Monthly Historical Documents Program.

All prior “back issues” are available for purchase by subscribers.

North American Rocket Transport

In 1965 North American Aviation produced a study for NASA about reusable space launch vehicles to support forthcoming expected space stations. Included within that study was an alternate use of rocket vehicles… point-to-point hypersonic commercial passenger transportation. This concept goes back to the late 1940’s and has continued to the present day, with the Elon Musk suggesting that the SpaceX Starship could be used for that purpose. The idea is interesting and it certainly *could* work. But could it be commercially cost effective? History with craft such as the Concorde and the Shuttle argue strongly against an early vehicle like this doing anything but losing truckloads of cash every time it launches.

From April 1959. Boeing won the competition to build the Dyna Soar with a desing that looked a lot *unlike* the Dyna Soar they actually started building; ironically, Martins design from December 1958 (working with Bell Aircraft) was far closer to the final Dyna Soar in configuration.

Once again Patreon seems to be becoming unstable. So I’ve got an alternate: The APR Monthly Historical Documents Program

For some years I have been operating the “Aerospace Projects Review Patreon” which provides monthly rewards in the form of high resolution scans of vintage aerospace diagrams, art and documents. This has worked pretty well, but it seems that perhaps some people might prefer to sign on more directly. Fortunately, PayPal provides the option not only for one-time purchases but also monthly subscriptions. By subscribing using the drop-down menu below, you will receive the same benefits as APR Patrons, but without going through Patreon itself.

Given the craziness going on, I decided that what the world clearly needs is something consistent. Like, say, me posting one piece of aerospace diagram or art every day for a month or so. So I’m going to do that. But in order to keep people from getting too complacent, I’m posting some of them on this blog, some on the other blog. Why? Because why not, that’s why. I’m slapping the posts together now and scheduling them to show up one at a time, one a day. Given the pandemic… who knows, this little project might well outlive *me.*

So, check back in (on this blog or the other) on a daily basis. Might be something interesting.

Possibilities of New Business Growth: Military Spaceplanes

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.

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.

Possibilities of New Business Growth: Cargo Return From Orbit

Nov 242019

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.
