Abstract: An ultrasound scanning assembly is configured to inspect a structure, such as a composite winglet of an aircraft. The ultrasound scanning assembly may include an outer ultrasound probe configured to be positioned on an outer surface of the structure. The outer ultrasound probe may include a phased array transducer having a plurality of transducer elements. An inner ultrasound probe may be configured to be positioned within the structure opposite from the outer surface. The inner ultrasound probe may include a single element transducer configured to receive ultrasound signals transmitted by the phased array transducer.

Abstract: In accordance with one or more aspects of the present disclosure, an apparatus for inspecting a part having a non-linear cross section includes a stationary sensor element including at least one phased array sensing unit, each of the at least one phased array sensing unit having a shape that is geometrically complimentary to the non-linear cross section of the part, and a support for the part having the non-linear cross section, the support comprising a drive assembly configured to move the part relative to the stationary sensor element, through an inspection beam emitted from the at least one phased array sensing unit.
