Boeing Model 987-350

A bit short of a week ago I posted artwork of a “Boeing Advanced Fighter.” This led to the re-discovery of the actual model number 987-350 (I knew it some time back, but my brain is full I guess). And that led to the below CAD diagram, coming in just under the wire for a forthcoming book. The 987-350 was a tactical supercruiser; armament is unfortunately left a bit vague in the available documentation. The artwork depicts it with four folding-fin AGM-69 SRAM missiles; another diagram depicts it with two larger-diameter missiles of similar length. All were to be semi-submerged for low drag.

Document: “Standard Aircraft Characteristics – Convair Class VF Seaplane Night Fighter (SKATE)” diagrams and data for seaplane jet fighter

Document: “21St Century Aerospace – The 20th Century Challenge,” General Dynamics presentation, late 80’s about hypersonics/NASP. From photographs.

Document: “Prototype X-14 VTOL Aircraft,” Bell Aerospace presentation, 1971, on the “SeaKat” operational naval VTOL. From photos, but art and diagrams were also scanned for clarity.

CAD Diagram ($5 and up): XB-70 Valkyrie forward fuselage configuration

If you would like to help fund the acquisition and preservation of such things, along with getting high quality scans for yourself, please consider signing on either for the APR Patreon or the APR Monthly Historical Documents Program.

I’m at work on a new series of CAD diagrams (see HERE for the first run) to be released as PDFs formatted for printing at 18X24. For example, here are first drafts of a few:

Boeing Space Sortie (3 sheets)
Saturn C-8/Nova
Jules Verne’s “Columbiad”
A-12 Avenger II (2 sheets)
Lockheed CL-400 “Suntan”

All of these require a bit more dressing-up, as well as explanatory text. But I think they’re starting to look pretty good.

I’ve selected a fair number more to work on. If any of these are of particular interest, or if any of the many, many diagrams I’ve made over the years would be of interest, let me know.

Northrop Low Altitude Penetrator

An artist used my diagrams of the Northrop Low Altitude Penetrator (a concept that competed against the design that became the B-2) to create a full-color layout. I wish I could work in color half as well…

The CAD vector-PDF, released in May:

And US Bomber Projects #2:

Which resulted in this:

The artist (Kurt Beswick) bounced an earlier version of the art off me and we discussed it for a bit. It was my opinion that a stealth bomber like this specifically designed to fly at near-treetop level (200 feet) would either be in green camouflage, or F-117 Nighthawk black. What do you think?

I’ve recently figured out how to get reliably good-quality vector graphic PDF files from my AutoCAD diagrams.These differ from standard “raster” graphics like GIFs and JPGs in that they are composed of scalable lines rather than pixels; this means that they can be printed off at many scales and they’ll retain clarity.

I think a lot of the diagrams would look quite good printed in large format; I’ve previously mentioned that I’m working on a few diagrams specifically for printing off on large format (24X36) mylar, but I’ve others that I think would also look good scaled for 18X24. I’m making these first seven diagrams available, formatted and scaled for 18X24. They can be viewed on screen, printed on a standard printer or printed by a large format printer all with equal clarity.

If this idea appeals, be sure to tell your friends, family, foes, anyone you think might be interested. Also be sure to comment if there are any diagrams I’ve previously created for APR, USXP or elsewhere that you’d like to see in this format. Some of them would be best as multi-sheet diagrams. Suggestions on how to improve also appreciated.
