| 摘要 | Wind turbine blades with layered, multi-component spars, and associated systems and methods are disclosed. A wind turbine blade system in accordance with a particular embodiment includes a first blade segment having a first spar element that includes first planks having a first thickness and a first plank composition, and a second blade segment having a second spar element that includes second planks having a second thickness and a second plank composition different than the first plank composition. The second blade segment is joined to the first blade segment at a joint, and, in particular embodiments, an overall product of thickness and elastic modulus of the first planks is approximately equal to an overall product of thickness and elastic modulus for the second planks. | ||
