A 1970’s Boeing concept for a variable geometry supersonic transport. Once the Boeing 2707 was cancelled in the wake of the oil crisis, any further work on supersonic transports focused heavily on “how do we make this more fuel efficient.” One approach was to go back to variable geometry, which had been dropped from the SST program when the 2707-200 was replaced with the 2707-300. The swing-wing of the -200 worked wonders for the low speed performance of the aircraft, but played hell with cost and weight, enough so that the -300 had a fixed modified delta wing.

The solution shown below linked a few technologies. One concept that showed promise was the “oblique wing,” as tested on the AD-1. A single-piece stricture connected to the fuselage at a single pivot point; much lighter and simpler than a traditional two-pivot swing-wing. With sufficiently rigid structures – think “carbon fiber” – the forward-swept portion could remain reasonably flat even at high speed. But this concept went one step further and linked *two* fuselages to not only a single oblique wing, but also an oblique tail. This would put the “aft” fuselage behind the shock wave shed off the nose of the “forward” fuselage, greatly reducing drag. You’d have the capacity of two SSTs for the operating cost of little more than one. Neat idea… very complex. I’m not sure if it made it much further than preliminary wind tunnel testing.

Here are some screenshots snagged from a not-quite-final version of the book, showing the sort of content you can expect from the final product.

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.

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.

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.

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…

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.

Here is an incomplete look at the diagrams created for my first book, “Boeing B-47 Stratojet and B-52 Stratofortress; Origins & Evolution.” It can be pre-ordered either directly from the publisher (with publication expected in late September) or through Amazon (looks like they’ll have it two months later). It is also expected to be on certain store shelves… more on that when it’s confirmed.

A few of these diagrams will be compressed to several-per-page; a few of them here are already shown in multiple optional layouts. But there are also a dozen-ish diagrams *not* shown because they are incomplete as yet. This gives an indication of the size and scope of the project…
