Blended Wing Bodies
« on: August 16, 2007, 11:30:38 pm »
A preview of issue V1N3 of Aerospace Projects Review. The original version had an article on a single one of these BWB designs... the revised issue describes the lot of 'em.

And yes, they are to scale. One of these design is obviously... kinda big.

Is that top one the nuclear powered one?

Yup! VTOL, as well. Lockheed sometimes thinks big and nutty.

VTOL? Like take-off in a day?  :P
A 747 weights about 60 metric tons, this would be like a 1000-2000 metric tons (if not more)
The runway would be gigantic in length ( and width)
They could make a runway on top of this thing for other planes to take-off from :P
Nice to have such ideas :D

Version I saw was a seaplane as I recall.  As for using runways all you need is enough wheels to get the ground pressure down (see the Pelikan for example) and a wingloading to make the takeoff distance reasonable.  It's not rocket science.

5386 metric tons, actually.

And hense the hundred and fifty or so lift jets for VTOL operations.

Interesting you should say that. See the little fighter-sized craft near the port side of the nose? Well... guess where it and 23 of its closest friends were meant to operate from...

There's a picture around on this site of one in flight with four KC-135s DOCKED to the trailing edge.  :o

The great little book "Future Fighters" has a Lockheed painting of this critter. The books author speculates that it was to be a seaplane, but it was strictly land-based.

Yup. There were two versions of this, with that one being STOL rather than VTOL. Fewer lift jets.

First place I saw it back in grade school.  ;)

Jr. High for me. While the '40's and '50's were the Golden Age of "projects," I think the '80s was the Godlen Age of Current Projects Publications. The books published back then  were jam-packed with quality artists impressions of what was on the planning boards. Today there are *far* more bits of art available... but most of it is computer generated crap.

Something I've noticed is that as PowerPoint and similar desktop publishing programs became available, the quality of presentations has gone *down.* In the 1960s, if you had a presentation for the USAF on, say, your neato new fighter design, you had the art department put together a package of drawings and paintings. Today you cobble together some MS Paint sketches yourself. Bah.

The 80s were the years you could go down to Waldenbook almost every weekend and pickup a new book or two by Salamander Publishing and others.   :'(
