Another rare piece of early Dyna Soar color art. This one shows the Dyna Soar heading to space atop the centaur upper stage of an Atlas booster. And if you think you are seeing corrugations on the back of the spaceplane, you are correct. At this stage in the design process the Dyna Soar *did* have some fairly massive, un-aerodynamic corrugations, and for the same reason why the SR-71 has corrugations on the wing: to allow for thermal expansion. Why exactly the Boeing Dyna Soar corrugations run crossways to the airflow, I’m a little unclear on. Terrible aerodynamics, but I imagine that’s just the way the structure wanted to flex.

The corrugations rarely appear on the usually simple diagrams you see of early Dyna Soar configurations, but they were there on full-scale mockups.

A piece of NAA concept art from the late 50’s or very early 60’s depicting a “space taxi.” Such devices were a common staple of space station thinking well into the 60’s, though it’s difficult to tell just how serious of a design this one was. The canopy, for example, seems an odd choice. The shape of the bubble and of the hatch indicates that this was not designed to hold pressure; the fact that the pilot is shown in a full space suit backs that up. It would make it difficult for the pilot to enter and exit the craft. And of course, the taxi is shown without reaction control thrusters, making it rather difficult to maneuver the thing. Very likely this is an artists fantasy done purely for marketing, showing people things they expect to see. Note, for example, that the space station appears to be cribbed directly from the Collier’s series. And if the station was rotating, that door would be in the *floor.*

Now available: two new US Aerospace Projects issues. Cover art was provided by Rob Parthoens, www.baroba.be

US Bomber Projects #20:XB-59 Special

US Bomber Projects #20 is now available (see HERE for the entire series). Issue #20 collects all the previously published articles and diagrams of the XB-59 antecedent designs and updates them. Additionally, more antecedent designs have been included as well as several designs that followed along after the XB-59. The biggest USXP publication yet!

USBP 20 includes twenty nine unique aircraft concepts (the usual issue of USXP has eight designs) from Boeing Models 484 and 701 showing how Boeing evolved the XB-59, their competitor to the Convair B-58 “Hustler.” Beginning with subsonic flying wings, the concept saw concepts both conventional and unconventional before eventually settling on Model 701-299-1, the final XB-59 design. This issue includes a half dozen Model 701 designs that followed along after the cancellation of the XB-59 program.

USBP #20 can be downloaded as a PDF file for only $8:

US Launch Vehicle Projects #04

US Launch Vehicle Projects #04 is now available (see HERE for the entire series). Issue #04 includes:

Space Carrier Vehicle: A US Army lunar rocket with 8 F-1 engines
Convair Reusable Helios: A stage-and-a-half monster with a gas core nuclear engine
Boeing Model 896-111: A 1980’s two stage transatmospheric vehicle
Project RAND Satellite Rocket 3-Stage: A 1947 satellite launcher
Convair Saturn V-R: An idea on how to make a fully reusable Saturn V first stage
Lockheed STAR Clipper: A 1968 stage-and-a-half lifting body Space Shuttle
Shuttle-C: The Shuttle derived vehicle design that came closest to being built
Titan III Growth/156-inch boosters: A more powerful version of the Titan III for Dyna Soar launch

US Bomber Projects #14: System 464L Special

USBP#14 brings together the competitors to Weapon System 464L, the first major effort in the Dyna Soar program. These designs were previously shown individually in prior issues of USBP; here they are brought together, with some updates, as well as a few extra diagrams and a section of diagrams formatted for 11X17 printing. This issue includes info and diagrams of the Lockheed, Republic, General Dynamics, McDonnell, Boeing, Douglas, Northrop, North American and Martin-Bell entries as well as their various booster systems. Also included are detailed diagrams of the ultimate Dyna Soar design, the 2050E.

USBP#14 can be purchased for downloading for the low, low price of $6.

In the footsteps of SpaceX: Chinese company eyes development of reusable rocket

A private Chinese company wants to build a reusable rocket that looks a *lot* like the Falcon 9. Refreshingly, they at least acknowledge that they’re basically copying SpaceX. It uses the same recovery system as the Falcon 9, roughly the same landing gear, same sort of grid fins for stability. Second stage looks pretty stubby, though. It’s a much smaller rocket than the Falcon 9, designed to put dinkysats into orbit.

Both US Launch Vehicles Projects #04 and US Bomber Projects #20 (XB-59 Special) are done and in the editing phase. I’m hoping to have them ready in the next few days.

A rare piece of color art of an early Dyna Soar being lofted atop an Atlas/Centaur. Color artwork of the Dyna Soar was created in some considerable abundance, but it was mostly reproduced in B&W, and its sadly rare for even those B&W reports to have been printed well, rarer still for them to have been scanned or copied well.

Currently on eBay is a nice wind tunnel model set of parts for the Douglas D852. The design is not immediately known to me, but I suspect it’s an early 60’s concept, perhaps a very early TFX (eventually the F-111) or some other variable-sweep fighter. Anyone know?

Recently on ebay were a set of 8X10 glossies, vintage Convair artwork depicting early spacecraft and launch vehicle concepts. I had my bid in… and was sniped in the last few seconds. Oh well. Anyway, one of the more interesting images was this one of the Convair “Helios” developed by or for Krafft Ehricke… a chemical rocket first stage equipped with wings for glide recovering and a nuclear powered second stage with a “tractor” arrangement to separate the nuclear engine from the payload – essentially a small manned laboratory to land on the moon. The second stage would unreel something like half a miles worth of cabling and drag the payload along behind it, relying on distance rather than physical radiation shielding. The second stage would take the payload all the way to the lunar surface, gently lowering it down at the end of the cables, then land Way Over There Somewhere. A modern design would, I would hope, include electrical cables and would serve as a power generator.

A middling-resolution scan of the same image was posted back in January. One day I shall get a clean high-rez version. If that day is a particularly glorious day, it will come not only with the other images created for the Helios project… but they’ll also be in color.

A great little video showing the C-5/Minuteman drop tests carried out in 1974. Two things in particular stand out: how quickly the project proceeded, and how spectacular some of the failures look. A third thing stands out: that there were spectacular failures and yet they quickly fixed their issues and move on to the next test.
