Abstract: An electrical interconnect including an electrically conductive male interlock having a substantially flat base portion and a longitudinally extending locking member, and an electrically conductive female interlock having a first retention groove in a support member, the first retention groove for receiving and retaining the locking member on the support member. At least a portion of the locking member is disposed on a surface of the female interlock and slidably received in the first retention groove to form a first locked position so as to enable electrical conduction.

Abstract: In one aspect, a spinner fairing includes a base configured to be fixed relative to a hub system; a movable spinner assembly movable relative to the base; the movable spinner assembly comprising a first movable member and a second movable member. Each first and second movable member being selectively configurable between a closed position and a contracted position, in which the movable spinner assembly has a decreased shape and/or volume. In another embodiment, a spinner fairing can include at least one static member and a moveable member. In still another embodiment, a rotor head fairing assembly includes an upper housing and a lower housing coupled to a hub system; the upper housing including an upper movable member; the lower housing comprising a lower movable member. In yet another embodiment, a rotor head fairing includes at least one moveable upper housing and lower housing.

Abstract: A thermally conductive curing process adds conductive additives to create pathways for dissipating heat during a curing process, thereby reducing the cure time, increasing the output capability, and reducing cost. Conductive particles or short fibers can be dispersed throughout the resin system or composite fiber layers in pre-impregnated or RTM-processed composite material. By disposing conductive particles or short fibers in a resin as part of the curing process, heat generated during the curing process can dissipate more quickly from any type of composite, especially thick composites. Conductive additive examples include multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWCNTs), graphene/graphite powder, buckyballs, short fibrous particulate, nano-clays, nano-particles, and other suitable materials.
