Wing utilizes principle of lift created by air which is moved over airfoil, drawn or sucked, by propeller at rear of channel, creating powerful lifting force on wing before plane starts its forward roll; channel shape confines air within venturi so that flow depends only on suction of propeller for constancy and is not materially affected by wind changes; Wright Field engineer testified that, based on wind tunnel tests, channel wing was capable of direct lift; competition with helicopters seen.
