Here are some screenshots snagged from a not-quite-final version of the book, showing the sort of content you can expect from the final product.
As before it is available for pre-order from both the publisher and from Amazon:

A photo taken from the first stage of a Saturn I showing the second stage’s six RL-10 rocket engines firings, boosting the S-IV stage towards orbit. Also visible are four orange-yellow exhaust plumes from ullage rockets… solid rockets that provide just enough acceleration to the stage to settle the liquid propellants at the bottoms of the tanks (otherwise the turbines might suck down vapor rather than liquid and that would be a Very Bad Thing).
Photo was from a 1965 magazine advertisement for Pratt & Whitney, manufacturer of the RL-10 engine. The full rez scan of the ad has been made available at 300 DPI to all $4/month patrons/subscribers in the 2021-10 APR Extras folder at Dropbox.

Yeesh. I continue to successfully get rewards out to Patrons and subscribers in a timely fashion… but I also continue to fail to publicize the fact. Last day of September, the rewards for that month were sent out. The September 2021 rewards included:
Diagram: “Early X-3 cutaway:” A large format cutaway illustration of a not-quite-final Douglas X-3 configuration
CAD Diagram: the command module of the Solem “Medusa” nuclear pulse propelled spacecraft
Document: a giant 1100+ page “Data Sheets for Ordnance Type Materiel,”1962 US Army “catalog”of pretty much all their stuff. Includes an illustration (often, though not always, including a basic diagram) and data for everything from trucks to tanks to bayonets to pistols to rockets.
Patrons should have received a notification message through Patreon linking to the rewards; subscribers should have received a notification from Dropbox linking to the rewards. If you did not, let me know.
If this sort of thing is of interest, sign up either for the APR Patreon or the APR Monthly Historical Documents Program.

Early/mid 80’s artwork depicting an X-Wing vehicle (a helicopter with very rigid rotors that could stop in flight to serve as wings). The text attributes this to Boeing-Vertol, but I could swear I’ve seen it attributed to someone else (Lockheed? Grumman?).
The X-Wing concept seemed to have great promise, but testing showed that, perhaps unsurprisingly, it had severe problems during transition. Had it worked, though, it would hve provided the high speed and long range of a conventional aircraft with the hovering efficiency of a helicopter.

A 1964 Boeing design for an orbital HL-10 derivative, to be used for space station logistics. This would be launched atop a Saturn Ib. Cargo would be carried up int he adapter, which would be expended; passengers would go up and down within the body of the spaceplane. A heat shield would cover the canopy until after re-entry.

My next book is slightly behind schedule, but it is coming. I was recently sent the first “proof” of the book after the graphic artists laid it out; a bit of tinkering yet, but it is nearing completion. I thought it might be interesting to post a shot of the last page.

The Baade Type 152 was an East German airliner, started 1955 and cancelled in 1961. It would have been a fantastic design immediately after WWII, but by the time it actually flew it was going up against far more modern designs such as the 707. Nevertheless, here’s an ad from 1960 trying to sell this dinosaur to the airlines of the world.

An animation of one of the Lunar Escape System concepts. The idea was that if the lunar module ran into some sort of trouble and couldn’t launch back into orbit, the ascent stage could be torn apart and jerry-rigged into a minimalist launch system… essentially a couple of lawn chairs stuck to a few propellant tanks and a rocket. Could it have worked? Sure. Would it have worked? Ehhhhhh….
If it’s “do this crazy thing or give up and die,” I can see the Apollo astronauts getting straight to work.
