Mar 312021

Just released, the March 2021 rewards for APR Patrons and Subscribers. Included this month:

Diagram/art: a large format scan of an artists concept of the XC-14. This was printed with a large number of signatures; they seem to be Boeing engineers.

Document 1: “Project Hummingbird.” An FAA document summarizing the characteristics of STOL and VTOL aircraft circa 1961, including bogh built and proposed types. This was scanned from a clean original!

Document 2: “The Thor Missile Story.” Old, old, incredibly old school media… a film strip propaganda piece about the statues of the Thor IRBM.

CAD diagram: the WWII era German DFS 228 rocket powered high altitude recon plane, proposed operational version.

If this sort of thing is of interest, sign up either for the APR Patreon or the APR Monthly Historical Documents Program.

Because I forgot to mention the January and February rewards… subscribers/patrons got these (new subscribers can order them as back issues):

January 2021: Titan IIIC/IIIM booster rockets; CAD diagram of Post-Saturn concepts; a Convair Heavy Bombardment Airplane brochure; a fractional XF-103 mockup review and technical description; a fractional Westland paper on VTOL; a General Dynamics report on a proposed turboprop transport for Saturn stages.

February, 2021: An Aerion SST brochure; a Lockheed SST diagram; Dornbergers report on a commercial rocket powered airliner (scanned from a clean vintage copy); an early Convair jet flying boat bomber brochure; a CAD diagram comparing General Atomics’ ten-meter Orions for the USAF and NASA.

Orbital HL-10 Artwork

Jan 192021

A ca. 1964 Boeing rendering of an HL-10-derived spaceplane in orbit. Numerous companies – Boeing, McDonnell, Lockheed, Northrop, etc. – contemplated the development of a logistics spaceplane based on the HL-10. The spaceplane itself would, rather like the X-20 Dyna Soar, have been minimally functional in space; most of the propulsion and power would have come from the attached adapter module. The conical adapter would have also carried the bulk of the vehicles payload to be delivered to orbit, and would be used to provide a de-orbit burn for the spaceplane. The adapter would therefore burn up on re-entry, leaving the lifting body to glide to a runway landing. The spaceplane itself would be crammed full of astronauts and the life support they’d need; there would generally be little capacity for anything else, certainly not payload going back downhill. This was fine, though, as there were few enough payloads other than humans that made sense to send *back* down the gravity well.

Stratolaunch starts building Talon hypersonic plane for Mach 6 flights

Construction is underway of an unmanned rocket-powered aircraft to be carried by the Stratolaunch “Roc” aircraft. The Talon-A is supposed to be something like the proposed X-24C… a lifting body hypersonic platform that can have various experimental units – including scramjets – attached to it. The Roc would be capable of carrying three Talon-A’s at a time, though it seems unlikely that there’s a really good reason to do so.

STAR Clipper art

Nov 112020

A black and white bit of concept art that was sold on ebay a while back showing the Lockheed STAR (Space Transport And Recovery) Clipper space shuttle concept from the late 1960’s. This was a promising concept that used a lifting body orbiter with a wide, flattened rear fuselage that was liberally covered with rocket engines (a large range of engines and layouts were considered, including liner aerospikes). The shuttle was filled with liquid oxygen tanks and some hydrogen tanks; the bulk of the hydrogen was stored in a large V-shaped drop tank. This component would have been larger but reasonably inexpensive, jettisoned after deletion to be destroyed during re-entry or splashdown in the Indian Ocean. The vehicle would have continued on to orbit using the propellant remaining in the internal tanks.

A vast amount of information on the STAR Clipper is available HERE.

The STAR Clipper lasted a lot longer than many contemporary designs and went through a multitude of design revisions. it always seemed like it should have worked reasonably well… and it had the benefit of being aesthetically beautiful.

APR: October 2020 Rewards

Oct 312020

Rewards have just been posted for APR Patrons/Monthly Historical Documents Program subscribers. Included:

1: “Manned Aerodynamic Reusable Spaceship (MARS) Vehicle Design” a 1962 Douglas report covering a single stage “orbital airplane” of impressive size and design.

2: “Pretest Information 3.3 Percent 624A Aerodynamic Heating Investigation, NASA Langley Unitary Plan Wind Tunnel.” A 1963 Martin report describing a test of the Titan IIIC/Dyna Soar configuration.

3: Official XB-70 General Arrangement Diagram

4: CAD diagram: a 1974 Lockheed concept for a subscale Space Shuttle Orbiter Mach 9 flight test model, to be dragged behind a YF-12C and booster by an “Avanti” rocket (modification of the D-21B’s booster) with an internal SRAM motor in the orbiter.

If this sort of thing is of interest to you, either because you’d like to obtain these documents or you’d like to help preserve aerospace history (or both) please consider signing on to either the APR Patreon or the APR Monthly Historical Documents Program.

DC-3 Artwork

Oct 252020

An artists impression of the “DC-3” Space Shuttle concept. This was a two-stage system using two manned flyback vehicles with straight wings and turbofan engines. It was intended to be a low-cost approach, disdaining high performance for simple design and – theoretically – easy maintenance. The orbiter here had two jet engines in the nose for landing and flyback range extension; aerodynamic fairing would cover the inlets until after re-entry, jettisoned once the vehicles had decelerated to below Mach 1. The straight wings would be easy to build and low in weight compared to large delta wings, but of course they wouldn’t provide the same amount of lift. Consequently, the orbiter would less “glide” during the initial re-entry than “belly flop.”

I’ve uploaded the full-rez version of that to the APR Dropbox, into the 2020-10 APR Extras folder. This is available to any APR Patron or Subscriber at the $4 level and above.
