A Beech Aircraft Company concept for a civilian VTOL for the 1980s, from circa 1971. This would be a two-seater using tilt-ducts. This appears to be less “engineering” and more “art,” as there are some definite headscratchers about the design. Where are the engines? In designs such as these it/they are typically in the fuselage, driving the ducted fans with shafts. But no provisions for inlets or exhausts are evident. So the engines would probably be in the nacelles themselves but there doesn’t seem to be room for them. The cockpit canopy is expansive and would provide a *fantastic* view, but it seems to be sized only for people who have had their legs amputated. The configuration, unlike your average tiltrotor, seems perfectly capable of horizontal runway takeoffs and landings, but the use of skids rather than wheels would make that problematic. The disk loading would be impressively high, and the resulting blasts of air from the ducts would likely tear anything short of solid concrete to shreds.

The West German Weser Flugzeugbau revealed the design of the P 23 tiltrotor in 1963. This was to be a do-everything vehicle… civil passenger transport, cargo transport, troop transport, ground attack, flying crane. It was an attractive design with one turboshaft engine at each wingtip; the rotors tilted, but the engines were fixed. The engines also provided power to two smaller fans mounted in the tail for pitch and yaw control. Sixty years later, it still looks like it would fit well in the skies of today, and look futuristic doing so.

A video tour of the Hughes H-4 Hercules, the “Spruce Goose.” This would have been a hell of a plane had it been made available several years earlier, but by the time it flew it was not only no longer needed, it was obsolete. being made largely of wood, its durability out in the world would be questionable. During wartime this might have been a small issue; they probably couldn’t be expected to have a long lifespan. They’d get taken out by enemy action, by crashes and by wear and tear long before weather and aging would do them in. But in civilian service, the aircraft seems unlikely to have stood up well for long periods.

 

An all-metal version with turboprops? that might’ve been a hell of a sight to see all through the 1950’s.

Bell artwork circa 1983 depicting the proposed JVX tiltrotor, which would become the V-22 Osprey. The cockpit and the sponsons display the greatest obvious differences from the aircraft that would eventually be built, but the design seems to be largely just about there.

A circa 1983 illustration of the Bell JVX tiltrotor concept, folded for storage aboard an aircraft carrier. The JVX would be developed into the V-22 Osprey. The differences between this concept and the final vehicle are relatively minor, with the sponsons on the side, shape of the nose and apparently less-lifted tail being the most obvious.

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.

  • BIS “Daedalus” straship
  • Rockwell MRCC
  • Northrop Tacit Blue
  • Space Shuttle Main Engine
  • Boeing Bird of Prey
  • General Atomic 86-foot Orion
  • General Atomic Orion battleship
  • General Atomic 10-meter Orion
  • Martin SeaMistress
  • Space Launch System
  • Have Sting orbital railgun
  • Casaba Howitzer
  • X-20 Dyna Soar
  • B-47E
  • DB-47E/Bold Orion
  • DB-47E/RASCAL

  • Boeing Big Onion
  • Shuttle C
  • Rockwell Star Raker
  • Lockheed STAR Clipper
  • Lockheed SR-71
  • Lockheed A-12 (early canards)

I looked through a small fraction of my surprisingly vast pile of CAD diagrams for some I thought might look good in really large format.

Back in 2016 I released seven PDFs of CAD diagrams formatted for printing at 24X36 inches (those are shown after the break). This was another product line that didn’t exactly blow up the market, and no further diagrams were released. But now that I have two books of CAD diagrams released, and two more coming (and potentially more after that), I’m considering trying again. The Lockheed CL-400 Suntan, A-11, A-12, SR-71, YF-12, along with several B-47 and B-52 related designs are possible, as well as designs that aren’t from those books (X-20 Dyna Soar, several Orion vehicles, etc.). If this sounds interesting, let me know; if there is something specific you might be interested in, let me know.
