Abstract
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.
