A page of illustrations showing the engine operation for vertical thrust for the V-460, compared to several contemporary Chance-Vought designs with wholly different propulsion systems. Note that the V-460 used the most complex system of the bunch, including not only vectoring the thrust from the cold-gas fans, but also using ejector effect to increase thrust from the hot-gas turbojet exhaust. In the 1960’s, the ejector effect was considered very promising, with both the Lockheed “Hummingbird” and the later North American Rockwell XFV-12 built to take advantage of that. But both designs showed the serious limitatiosn of the ejector effect to produce added thrust… while it worked great in subscale models, once scaled up to full size the losses in the system were so bad that it tended to reduce total thrust, not increase it.
