A 1953 General Electric study for a Convair C-99 cargo plane modified with nuclear turbojet propulsion. The pusher-prop engines were removed from the wing and replaced with a 65,000-pound AC-2 nuclear powerplant within the fuselage. This was equipped with two separate jet engines, giving a total sea level static thrust of 35,500 pounds. Two additional conventionally fueled J77 engines were mounted in the wings for takeoff thrust. A lead and polyethylene shielded crew compartment weighing 20,000 pounds protected the crew, giving radiation doses of 0.5 roentgen per hour.

A late 1970’s/early 1980’s design for a supersonic transport from Lockheed included an unusual engine layout… two turbojets on the underside, two turbojets on the topside. This would certainly prevent shockwaves from the inlet spike of one engine from interfering with the inlet of another nearby engine, but it would also make the engines on the topside somewhat questionable during high-alpha (angle of attack) flight, such as takeoff and landing. Note that the drawing wa made with an early CAD program.

A good scan of a bad photocopy of an advertisement published in Aviation Week sometime in the mid 1960’s shows a few depictions of rotating space stations. That was something American aerospace companies did back then… try to recruit employees with the promise of exciting things to come in the space program. Shrug. In this case, the stations appear to be single-launch designs that would expand or unfold once in space.

Anyway, this is a bit of further information related to a piece of artwork previously posted HERE.

Alex Tremulis was an industrial designer. Best known for designing the Tucker automobile, he spent WWII in the Army Air Corps at Wright Field designing advanced combat aircraft. One of the most interesting designs he produced was known as the “Zero Fighter,” a rocket powered interceptor which had a large booster rocket first stage.

I mastered parts for a kit of the Zero Fighter for Fantastic Plastic. FP has just released the 1/48 kit.  I understand that this is a limited run kit, so get yours soon…

The concept of an orbital fuel depot, supplied from Earth in order to fuel missions to Mars and the like, is not especially new. Shown below is a concept from General Dyanamics from 1963, depicting a toroidal propellant depot. A torus is a rather poor shape for such a thing… not only is it heavier than an equivalent-mass spherical tank, it also has substantially more surface area. But the advantage of this configuration is that it would easily pack in excess payload space aboard a partially-loaded Nova launch vehicle. Dimensions weren’t given, but maximum diameter would be less than 70 feet.

A few years back I received in trade a number of diazo “blueprints” (white paper, blue lines). tucked in among ’em were a number of SST diagrams, including two very large & detailed Boeing 2707 layouts… the original 2707 (swing wing) and 2707-200 (swing wing & canard). These were about 3 feet by 8… very big. And as with virtually all blueprints that were actually made to be used, they were folded, not rolled. Having been folded for 40+ years meant that they were a scanning nightmare… the paper was very stiff, and had it been fed through a  large format scanner it would have produced dismal results. The best way to deal with such prints is to unfold them an either compress them (impossible give the size) or roll them up, and leave them to st for several months. I rolled them up. And forget them for several *years.* Just found ’em again. They are fragile, but have “relaxed” from being folded, and are now happily cylindrical.

I think they’d make dandy cyanotypes. They would have to be smaller than the originals, however… 2 feet by 5. Anyone interested? They’d be pretty pricy, on the order of $80-$100. But you’d be the only kid on your block with one…

In the early 1960’s, NASA wanted the Nova rocket: a launch system capable of orbiting around one million pounds. The primary missions included manned lunar and Mars missions, space station launches, that sort of thing. But other missions were contemplated, including military missions. Information on these military missions is pretty lean. This is most likely due to the fact that Nova was a NASA project with minimal DoD input… thus there would have been minimal actual work done on military launch planning for Nova. Nevertheless, a few snippets of military Nova data have come to light from time to time.

A General Dynamics/Astronautics presentation to NASA in August 1963 had a few paragraphs and a few charts discussing military missions. Sadly there was little more; it is impossible to determine if these concepts were actually requested by NASA or not, and whether these ideas went any further. BAMBI (BAllistic Missile Boost Intercept), an anti-missile satellite system, was studied by General Dynamics at the same time as Nova, and has largely remained classified (or at least, little has been made public). Like the anti-missile satellites studied during the SDI program of the 1980’s, for BAMBI to have had a chance of success at taking out a massed Soviet ICBM strike, a large number of the satellites would be needed. In the NOVA presentation, 14 million pounds worth of satellites  – each weighing 4,000 pounds – were claimed as needed. In this case, launching 3,500 or so satellites would be a chore that Nova could handle easier than much smaller launch vehicles.

More unconventionally, Nova was also proposed as a logistics transport. In this case, it could be used to chuck a capsule across the planet sub-orbitally… a capsule with 2.5 million pounds of payload. Additionally, Nova could put a 1 million pound capsule into orbit; the capsule would de-orbit itself and land to disgorge infantry. Orbital systems were in a way prefered, as orbital systems meant that the Nova itself would go into orbit. This meant that the Nova could de-orbit on command an return to Earth at convenient locations for recovery; ballistic lobs would essentially throw the Nova away. The orbital capsule was at least illustrated with a drawing.

Finally, Nova could be used to launch offensive weapons. One million pounds were the weights given, so presumably these were meant to go into orbit. The weapons loads were remarkable, and more than a little spooky:

  • 10,000 megatons worth of nukes (speculation: 10,000 one-megaton warheads)
  • Enough chemical weapons to kill everyone in a 1,000 square mile region
  • Enough biological weaponry to kill everyone in a 1,000,000 square mile region.

Note… these weapons loads are for a single launch.

Not provide in the presentation – or anywhere else that I’ve seen – is NASAs reaction to the idea of using their rocket to launch a million square miles worth of biological horror.

Grumman 619 orbiter coming in for a powered (turbojet) landing. Note the white underside… it is very unlikely that the underside would actually be painted white (much less that it would survive re-entry); instead, this is almost certainly artistic license.
