A lightweight wind turbine blade formed with a truss support structure assembly of composite truss joints including composite spar and cross members attached to and supporting in spaced relation a spine of lightweight rib panels. The rib panels are oriented in parallel spaced relation from one another and individually molded with perimeters defining individual areas of curvature for the finished blade assembly. The truss support structure is covered with a lightweight fiberglass or hardened fabric skin attached to and fitted on respective rib panel edges forming an airfoil structure.

We claim: 1. A method for operating a wind turbine, comprising:carrying multiple wind turbine blades with a spindle,transmitting loads from at least one of the wind turbine blades to the spindle via a truss structure that includes a wind turbine blade skin, a plurality of spaced-apart wind turbine blade rib panels positioned within the skin, multiple spars connected to and extending between neighboring rib panels in a spanwise direction, and multiple cross members extending diagonally between neighboring spars; andsubjecting the wind turbine blades to cyclically varying gravitational loads by rotating the spindle about a generally horizontal axis.
