A combo of computer aided  design and machining with low-cost Chinese labor and an expansion in the market for model kits has in recent years led to the availability of model kits the likes of which would have been simply unthinkable when I was a kid. For example: the P.1000 “Ratte.” The Ratte was one of the goofier ideas to come out of Nazi Germany, a 1000 ton tank that used two U-boat diesel engines to haul around a turret from the Tirpitz-class battleships packing two 38-cm cannon. The idea – beloved of Hitler –  was clearly insane and while  some doodling on the concept was done, no evidence of serious engineering has come to light. It’s the sort of idea that would not be seriously contemplated either as a weapon of war or as a commercial high production run injection molded kits.

Except…

A few years ago, the Chinese model kit company “Takom” released an injection molded kit of the Ratte in 1/144 scale. Even at that small scale the model was good sized, because the design was just that insane. I was honestly a bit shocked that someone would go to the trouble of releasing a 1/144 scale kit of the Ratte. But now there’s this:

A Ratte in 1/72 scale, in a box big enough to make a dog house out of. The company behind this, Modelcollect (another Chinese company), has a whole range of truly befuddling designs. Not only perfectly understandable models like 1/72 B-52s and B-2s and, at long last, a 1/48 A-12 Avenger II, but also a bunch of WWII German tanks redesigned as walking “mechs.” I dunno. Well, the Japanese go bughouse for model kits of ridiculous giant fighting anthropomorphic robots, so maybe the Chinese like quadrupedal King Tiger tanks. Well, there are two billion Chinese, so it doesn’t take a big market share to still end up with a big market.

A photo found for sale on ebay a while back shows a display model (circa 1973) of a Rockwell International concept for a Grumman Gulfstream 2 corporate jet modified for VTOL capability. This was not meant to be an operational concept, but a research vehicle to demonstrate VTOL technologies and operations in a jetliner-like aircraft, with the potential to be implemented into larger passenger-carrying jetliners such as the DC-9. This would allow such airliners to operate from smaller airfields. But the fuel-hungry nature of VTOL aircraft put an end to such notions in the 1970s. This aircraft would have used lift fans in flattened pods on the wings (each pod containing two YJ97 GE-100 gas generating turbojets) and vectorable-nozzle forward-thrust fans (again with two gas generators), for a total of six jet engines.

Turns out that the “Museum of Flying” has on display a large model of the Douglas Model 2229 supersonic transport. This design was studied for the FAA in the early 1960’s, and would have gone up against the likes of the Lockheed L-2000 and the Boeing 2707… had Douglas not determined that SSTs were economically infeasible and dropped out early. Consequently, the 2229 is one of the more difficult designs to get any good data on. I’d love to get a bunch of photos of this model from every conceivable angle (especially orthogonal views) and, it at all possible (very likely not), I’d also love to get measurements.

Someone visited back in 2015 and posted a few photos:

For all I know the museum may also have a nicely detailed engineering study document tucked away in their archive, but I have no “in” there to find out.

Just slightly out of my means just at the moment, but it does appear to be a remarkable piece of work. The condition is a bit regrettable, but I bet in earlier days it was probably pretty close to indistinguishable from the real thing. If you have an interest in the NF-104 aerospace trainer, I guess you aught to have one of these.

A photo of a 1960’s Bell Helicopter concept for a high-speed tiltrotor. In this design the aircraft would operate in hover and low speed much like the V-22, but at higher speeds the prop-rotors would stop rotating and fold back to reduce drag. Forward thrust would be provided by pure jet exhaust from the convertible turboshaft engines within the fuselage.

I have uploaded high-rez scans of the color glossy photo to the 2018-08 APR Extras folder on Dropbox for APR Patrons at the $4 level and up.

If you are interested in this image and a great many other “extras” and monthly aerospace history rewards, please sign up for the APR Patreon. What else are you going to spend $4 a month on? Taxes? Bah. Invest in the APR Patreon instead.

For nearly fifty years, “2001” nerds like me waited for a decent, kinda-affordable model of the “Discovery” spacecraft. And last year Moebius  produced just that, a 1/144 scale injection molded kit that anyone with somewhere between $150 and $200 could get.

And now Kaiyodo has shown their 63-inch-long 1/96 scale Discovery, which will apparently retail in the area of $400.

Also coming is a 1/8 scale Space Pod complete with interior detail.

Modeling of all the parts is done. Some refinement is probable, as some of the bits shown here – the plumbing lines in particular – are pretty small. The plan is to include the walkway to connect the two vessels. In all likelihood the walkway will be a single solid-cast part.

Both vessels are modeled at a higher resolution than is necessary for 1/144. They’re be great at 1/72, perhaps even 1/48. but there are currently no plans for larger-scale (and much more expensive) kits.
