External air is caught by the lift fans and pushed underneath the craft’s hull into the space defined by the aluminium hull, the ground surface and the flexible hovercraft skirt.
Increasing lift fan speed results in higher volumes of air entering the skirt causing inflation and an increase in trapped air pressure, raising the hull of the craft above the surface.
As the air pressure increases further the craft reaches its full hover height and air starts to escape underneath the skirt. The hovercraft on full hover is almost friction-less over the surface.
High volumes of air is pushed through the hovercraft’s ducted thrust propellers to provide the propulsion over varying surfaces such as water, ice, sand, mud, weed, debris and obstacles.
