  • Patent number: 8322647
    Abstract: An aircraft includes a housing and a powerplant coupled to the housing and configured to rotate a drive shaft around its longitudinal axis. The aircraft may include at least one lift fan assembly coupled to its housing and including a gearbox and at least one lift fan. The gearbox is coupled to the drive shaft and configured to transfer rotational energy from the drive shaft to the lift fan or fans. The lift fan assembly or assemblies may include at least two pivot assemblies, the first pivot assembly configured to pivot the lift fan assembly on a first axis and the second pivot assembly configured to pivot the lift fan assembly on a second axis that is substantially perpendicular to the first axis.
    Type: Grant

  • Publication number: 20050034647
    Abstract: The invention is Hull Suspension Technology (HST), a specific technology which incorporates mechanics and hydrodynamics to allow the bottom rear part of the vessel hull to fluctuate up and down to counter water surface and stabilize vessel movement while the vessel is in operation. HST also utilizes hinges to mount the stern and bow hulls together efficiently, and implements shock absorbers in its design, which dampen the impact of outside factors and streamline the overall movement of the vessel during operations.
