SpaceX has landed another previously-launched Falcon 9 first stage (it flew a resupply mission to ISS in February). It’s not there yet, but this sort of thing is becoming routine… which is fantastic.

Note that at about the 21 minute mark the grid fins begin to glow white-hot during entry. Which would certainly explain why they switched from aluminum to titanium for those fins.

Got them done a little early this time, so here’s a review of what the APR Patrons will be receiving:

Patrons will receive:

A proposal brochure on the C-135A cargo transport

A brochure about the Shuttle-C

A well illustrated NASA-produced booklet from the mid 1980’s describing the space station as them conceived

A large format diagram showing a wind tunnel model of the Titan III/Dyna Soar

A CAD diagram of the ca. 2001 Russian TsAGI Integrated Wing Body large passenger transport jetliner

If these are of interest, please consider signing on to the APR Patreon.

I have a number of new aerospace cyanotype blueprints available. Until I can repave the catalog page, I have slapped together a PDF catalog of the new items. Until Wednesday, I’m making these new 12X18 prints, as well as the earlier 12X18 prints, available. The earlier 12X18s are viewable HERE. The new items are in the following PDF file:

Cyan catalog addition 2017-10

If any are of interest, Paypal to the email address in the PDF file, and add a note in the order which items you want…. AND what your mailing address is (PayPal doesn’t automatically add the address to payments like this).

After Wednesday the prints will be again unavailable for a little bit while I retool and work on some things.

UPDATE: over for now. After some retooling I hope to have all the cyanotypes, small and large old and new, available for regular sale.

Elon Musk just gave a presentation in Australia, updating SpaceX’s plans for the interplanetary transporter. It seems they are indeed making some meaningful progress… with an aspirational goal of sending to of these rather gigantic landers to Mars in 2022 carrying cargo, and four in 2024… two of which are to be manned. Seems ambitious. But then… this is SpaceX, and they’ve accomplished some amazing things in the field of rocketry. if they’d just stop tinkering with that silly hyperloop and devote the effort and manpower to *this…*

It would be entertaining as hell of SpaceX gets the BFR up and running and shooting prototype interplanetary colonization ships to Mars before NASA even has the SLS ready to go.

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

 

USLP #04 can be downloaded as a PDF file for only $4:

Also recommended, these previous Specials:

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.

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.

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.
