I recently came across something on ebay that looked interesting; the buy-it-now price is a bit steep, so I googled it. Huzzah! It’s available online as a PDF. D’oh: my antivirus program freaked out that the connection to the university website is insecure. Huzzah! It has been archived on the Wayback machine.

This is a writeup, with photos and diagrams, of the July 11, 1962 news conference at NASA headquarters where the Lunar Orbit Rendezvous technique was described. prior to the the understanding was that the Apollo Command and Service Modules would land directly on the lunar surface; this sounds easy, but required a bigger booster than the Saturn V and would have put the astronauts far above the lunar surface (so far as I know, no determination of how exactly the astronauts were going to get some fifty or more feet down, and then fifty or more feet back up). LOR entailed the use of the Lunar Excursion Module,a small, lightweight spacecraft that could zip on down the the surface from lunar orbit and then hop on back up. Far less mass needed to go to the lunar surface, meaning the planned Saturn C-5 (later Saturn V) could take care of the whole mission in one shot. No need to assemble spacecraft in Earth orbit using multiple launches of hardware and propellant tankers.

Sep 232021

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.

L-2000 exploded view

Sep 102021

An exploded view of the Lockheed L-2000 SST project from the 1960’s. This was the second-place finisher in the contest to develop a US supersonic transport, losing to the Boeing 2707. The 2707 won in part because it had variable-sweep wings, giving it better low speed performance… but after the contest was won, Boeing’s design shed the overly-heavy variable geometry for fixed wings not unlike those of the Lockheed design. In the end that couldn’t save the 2707 from the chopping block. Many have wondered over the last half-century what might have happened had Lockheed won the contract instead. Perhaps the sky would be filled with SSTs. Perhaps the L-2000 would have been a failure of historic proportions, with prototypes crashing or exploding in flight. Or perhaps it would have turned out just like the 2707… once detailed development began costs would have ballooned, performance suffered and Congress simply walked away.

DC-X-200

The 1970’s saw a lot of airlines and airline manufacturers going to great lengths to economize, thanks in no small part to the spike in fuel prices and general economic downturn caused by the OPEC oil embargo. Some of this economizing came in the form of new “air bus” concepts to jam as many people as possible into mid-sized jetliners. Wide-bodied configurations were popular for that. McDonnell-Douglas proposed a new airliner in the mid-70’s that was derived from their long-range high capacity DC-10. The fuselage was cut short and stubby; the third turbofan at the base of the vertical tail was deleted. The wings and tail surfaces were all-new. This made it slightly more economical on a passenger-mile basis than the trijet, but also made it inappropriate for trans-oceanic flight since airlines were not yet ready to accept twin-jets for such routes. Intercontinental flight in twinjets would have to wait for the 777. McDonnell-Douglas figured that up to 278 passengers could be wedged into the available space… and that even more seats could be installed in the below-deck cargo bay.

SL-1: 260-inch solid rocket motor test firing

Jul 042021

Back when NASA dreamed big (the early 1960’s), there were many ideas for how to make really, REALLY big space launch systems. Solid rocket motors had a place at the time serving as either the first stage, or strap-on boosters for the first stage, for Saturn-class boosters. Most solid rocket production facilities are far from Cape Canaveral, so getting rockets from the manufacturer to the launch site could be a problem. Due to rail line restrictions, a case diameter of 156 inches was the limit: anything bigger wouldn’t fit through existing tunnels. But Aerojet and other companies had ideas for even bigger solids… I’ve seen drawings for boosters up to 396 inches in diameter, though 260 inches seems to be the largest given serious engineering.

In order to conveniently manufacture and transport these giants, Aerojet set up a manufacturing plant and static test site in Florida. Aerojet built several half-length versions of the 260-inch-diameter boosters, dug a hole in the ground, upended the rockets and fired them towards the center of the Earth, with the results being a small earthquake, a gigantic brown plume of solid rocket exhaust shooting into the sky and no production contract. The first test firing was in September, 1966, by which time NASA’s horizons had contracted substantially.

Solid rockets as an economical way to get to space, especially as a way to launch humans, is a technology whose day has passed. As military technology they remain as valid as ever; unlike liquid rockets, you can stuff a solid rocket into a silo and somewhat ignore it for years and then launch it on a moments notice. Having ICBM-sized boosters stocked up and stored away ready to launch a fleet of replacement GPS, communication and spy satellites when the Chinese swat our current fleet from the sky makes a lot of sense… but using solids to launch missions to the Moon or Mars is now a rather silly notion.

“Large Amphibian”

A 1980’s Boeing concept art depicting a passenger transport of 100 or so years in the future. It has a number of… interesting features including a front that opens up like an Arakeen Sandworm. The cockpit and a fair amount of space behind it hinge upwards to provide access to the sizable interior of the aircraft. The gigantic transparent canopies are certainly a remarkable feature. Even the passenger windows on the side are vast compared to the tiny human figures. The engines look somewhat small for the design, but at least they exhaust almost directly onto the vast canopy over the tail “lounge” area. Surely that’ll not pose any problems…

“Mastering the Transatmosphere”

Jun 192021

The June 1986 issue of “Air Force Magazine” had a cover article about the next big thing for the Air Force… aerospaceplanes capable of attaining orbit. Those who have been paying attention since 1986 might have noticed a dearth of aerospaceplanes, but at least the article has some spiffy cover art, along with interior art of what it claims is a 1965 McDonnell Douglas aerospaceplane. Two problems, though… McDonnell Douglass didn’t exist until 1967, and the art sure looks more like an SST to me. Shrug.

Anyway, I’ve uploaded a 300DPI scan of the article (and two ads… one depicting what appears to be a neutral particle beam space weapon, the other for a series of space-based nuclear powerplants) to the 2021-06 APR Extras folder on Dropbox, available to all APR patrons and subscribers.

Short PD.16

Jun 112021

The Short PD.16 was a circa 1957 design for a twin engined turboprop cargo/passenger plane. The configuration was similar to the Fairchild C-119, and would have been, by modern standards, an unusual passenger aircraft. Slow, voluminous, with (in one configuration) a cargo hold stuffed with cars and an upper deck filled with people in *luxurious* seating by modern standards, probably deafened and rattled. Half a dozen of one…

This was procured from eBay thanks to the contributions of Patrons and subscribers. The complete article has been sent to all patrons/subscribers at the more than $10/month level.

“Intercity Transport” art

May 142021

Another strange piece of 1970’s/early 1980’s Boeing art, this time depicting an “Intercity Transport.” What’s going on with that circular “inlet” on the rear upper fuselage? Damnfino. Just visible under the wing root is a low-set inlet, so that would seem to provide what’s needed for the propulsion system. If there was a vertical thrust system in the nose, and good low-speed control systems on the outer wings, then that circular inlet would be fore a VTOL system. But on its own? Hmmm.
