A layout drawing of the Chance Vought Corp. V-460, a VTOL cargo plane design from the mid 1960’s. It was unusual in having a tailless configuration similar to some designs put forth by German aircraft designers at the end of the second world war, but with a multitude of fans embedded within the wings. The fans were themselves driven by gas pressure produced by gas generators (read: “small turbojets”) located above the fuselage, and ducted through the wings. With this arrangement, the thrust lines of the engines roughly parallel the center of gravity of the loaded aircraft (when vectored down for vertical thrust). Thus all engines are used for both vertical and horizontal thrust, theoretically making a lighter weight, more efficient propulsion system… at the expense of added complexity in the hot-gas ducting.
