  • Patent number: 9758144
    Abstract: A hovercraft includes a lift air supply source having a dynamic air flow area in communication with a central lift air chamber to provide continuous air flow to the central lift air chamber and a static air flow area in communication with an inflatable skirt extending around a periphery of the hovercraft. Air flow from the static air flow area enters the skirt to replenish air leaking from the skirt. The static air flow area has less air flow than the dynamic air flow area. The static air flow area is located at a higher position than the dynamic air flow area to reduce the likelihood of water entering the inflatable skirt when the hovercraft is operated on water.

  • Patent number: 9751401
    Abstract: A torque distribution control system comprises a torsion unit for detecting traction on wheels of a primary driving axle that is continuously engaged with a drive source or a source of torque power. The amount of traction detected is converted to a signal with variable signal strength, the signal strength correlating to the amount of traction detected by the torsion unit. The signal strength capable of being adjusted automatically based on select parameters and/or manually based on a driver's input. And, in response to the signal, actuators engage and control operations of the vehicle such as the drive source, a braking system, and/or an axle clutch, with the level of engagement dependent upon the signal strength.
