20100263955 | SURFACE EFFECT SEA TRAIN - A multiple unit surface effect vehicle movable through an aquatic environment is provided including connected units and lift fans. The multiple unit surface effect vehicle may further include a coupling system and/or a plurality of skirt portions connecting one of the connected units with another of the connected units. The multiple unit surface effect vehicle includes the connected units connected to form a continuous movable unit movable in an aquatic environment. Each connected unit includes a forced air containment chamber defined within each of the connected units. The forced air containment chambers of each of the connected units are connected to form a continuous pressurized air cushion. The lift fans force air into the forced air containment chamber to pressurize the continuous pressurized air cushion. | 10-21-2010 |
20090166498 | Trailing edge blade clamp - A blade clamp for a helicopter blade having a width and leading and trailing edges includes a first clamping part, a first flexible liner attachable to the first clamping part, a second clamping part, a second flexible liner attachable to the second clamping part, a hinge mechanism to pivot the first clamping part and the first flexible liner with respect to the second clamping part and the second flexible liner and a connector provided opposite to the hinge mechanism. The flexible liners evenly distribute clamping force upon the blade clamp to prevent damage to the blade. The hinge mechanism allows the first and second clamping parts to open wide enough to safely and easily accommodate a helicopter blade during removal and installation of the blade. | 07-02-2009 |
