Description
The V-1000 was an all-metal jet-powered airliner of conventional layout, which in overall terms looked like a de Havilland Comet with a new fuselage or the Valiant. The fuselage section looks similar to any modern "narrow body" airliner, although the nose was a rounded ogive similar to the Comet's (a design note also copied on the Sud Aviation Caravelle). Although it may have looked similar, the V-1000/VC7 was designed for a six-abreast layout, and thus had a much larger diameter than the Comet.
The wing planform was largely that of the Valiant with engines embedded in the wing near the wing-root, which decreased drag but increased difficulty in maintenance and was later considered to increase the risk of fire. Later designs universally used podded-engines on pylons to address these concerns. The wing shared a number of design notes from the Vickers Valiant bomber. The tail surfaces were conventional, although the horizontal stabilizers had a pronounced dihedral to keep them clear of the jet exhaust.
The aircraft was designed from the start to mount the Rolls-Royce Conway engine, the world's first turbofan. The in-wing mounting dramatically limited the amount of bypass air, however, to about 25%. There are reports of a follow-on design, the V-1001, which would used under-wing podded engines instead.
Some of the design notes of the VC7 would go on to influence the Vickers VC10. In particular, the wing arrangement with the various high-lift devices proved useful in the "hot and high" roles the VC10 would later fill. Additionally, the VC10 was powered by the Conway, albeit in a higher-powered version with much greater bypass ratio.

“It [Egypt] has more wonders in it than any other country in the world and provides more works that defy description than any other place.”
—Herodotus (c. 484–424 B.C.)
“The Sage of Toronto ... spent several decades marveling at the numerous freedoms created by a “global village” instantly and effortlessly accessible to all. Villages, unlike towns, have always been ruled by conformism, isolation, petty surveillance, boredom and repetitive malicious gossip about the same families. Which is a precise enough description of the global spectacle’s present vulgarity.”
—Guy Debord (b. 1931)
“Whose are the truly labored sentences? From the weak and flimsy periods of the politician and literary man, we are glad to turn even to the description of work, the simple record of the month’s labor in the farmer’s almanac, to restore our tone and spirits.”
