  • Patent number: 6318489
    Abstract: A novel Ground Effect Machine capable of operating in low airflow and low air-pressure conditions. By using an air bladder, partially filed with liquid, in lieu of a skirt, the invention is able to reduce airflow, and consequently maximize the lift provided by air pressure pump, thus minimizing the amount of air pressure required. In addition, by alternating between positive and negative air pressure within a pressure chamber beneath the ground effect machine, the invention may lift and transport heavy loads or securely fasten the ground effect machine to the floor surface.
