Positive lift vehicle

摘要

An air vehicle includes a body having a top and a bottom and a support platform for carrying cargo such a people or equipment. An impeller mounted on the body is powered, such as by a motor, for rotating so as to create low pressure on the top of the body relative to the pressure on the bottom of the body so as to create lift. The body may contain buoyant gas sufficient to aid in lift. Air from the impeller may be directed to directionally control the vehicle. A plurality of impellers may be used.
