Abstract
Segmented wind turbine blades with truss connection regions, and associated systems and methods are disclosed. A wind turbine system in accordance with a particular embodiment includes a wind turbine with a first segment having a first position along the longitudinal axis and having a first internal load-bearing structure for which non-truss structure elements carry at least 90% of the shear loads in the first segment. The blade further includes a second segment having a second position along the longitudinal axis and having a second internal load-bearing structure for which non-truss structure elements carry at least 90% of the shear loads in the first segment. A connection region between the first and second segments includes an internal load-bearing truss structure connected between the first internal load-bearing structure and the second internal load-bearing structure.
