An automated, inspection system that includes a robot with a closed loop control system that includes multiple Nondestructive Testing (NDI) modalities for complete through-thickness inspection of structures (e.g., wind turbine blades, aircraft, pressure vessels, pipelines, ships). The robot can be programmed either by a user or another inspection system to automatically move to a user-specified location, or a series of locations to complete a scan inspection of the area. The inspection region (size) is also automated via a user-specified input, other inspection system, or through other pre-programmed coverage patterns. Closed-loop control software allows the robot to automatically return to the location of any damaged region, identified during the inspection, so that the location can be marked and appropriate maintenance actions can be taken.

Systems and methods for remote, automated non-destructive inspection

The present disclosure is directed to towerless vertical-axis wind turbines with pre-tensioned rotors. The present disclosure is further directed to a vertical-axis wind turbine (VAWT) with supported blade ends (e.g., Darrieus type) which replaces the center tower with tensioned supports, such as tensioned guy wires, and blade pre-load.

Towerless vertical-axis wind turbine

Various technologies described herein pertain to a vertical axis wind turbine blade configured to rotate about a rotation axis. The vertical axis wind turbine blade includes at least an attachment segment, a rear swept segment, and optionally, a forward swept segment. The attachment segment is contiguous with the forward swept segment, and the forward swept segment is contiguous with the rear swept segment. The attachment segment includes a first portion of a centroid axis, the forward swept segment includes a second portion of the centroid axis, and the rear swept segment includes a third portion of the centroid axis. The second portion of the centroid axis is angularly displaced ahead of the first portion of the centroid axis and the third portion of the centroid axis is angularly displaced behind the first portion of the centroid axis in the direction of rotation about the rotation axis.
