Abstract: A battery housing includes a first casing and a second casing. A side wall of the first casing is provided with a limiting groove along an axial direction of the first casing. A guiding rib is protrudingly provided on the outer wall of the first casing along the axial direction of the first casing. An inner wall of the second casing is protrudingly provided with a limiting protrusion corresponding to the limiting groove along an axial direction of the second casing. A side wall of the second casing is provided with a guiding groove corresponding to the guiding rib along the axial direction of the second casing. When the second casing is sleeved on the outside of the first casing, the limiting protrusion is engaged in the limiting groove, and the guiding rib is engaged in the guiding groove.

Abstract: A scoop inlet for a turbomachine. The turbomachine includes a core engine casing relative to a centerline extending the length of the turbomachine. Further, the core engine casing at least partially defines a bypass flow passage. The scoop inlet includes an inlet at the core engine casing in fluid communication with the bypass flow passage. The inlet includes a mouth fluidly coupling the bypass flow passage to a cooling system. The mouth receives bypass bleed air from the bypass flow passage and defines a width in a circumferential direction relative to the centerline. The scoop inlet also includes a bypass bleed duct defined through the core engine casing. The bypass bleed duct fluidly couples the mouth to the cooling system. In addition, the scoop inlet includes a plurality of droplets at the mouth of the inlet partially extending from the mouth into the bypass flow passage.

Abstract: A cable bushing assembly and a method of sealing a cable penetration through a housing are provided. The bushing assembly includes an interior shell, a central cavity and at least one aperture between a first face and a second face. At least one cable passes through the bushing assembly. The bushing assembly also includes an exterior shell at least partially circumscribing the interior shell. A clasp is located between the interior shell and the exterior shell to prevent separation of the exterior shell from the interior shell. Packing material seals the at least one cable within the interior shell. A method of sealing a cable penetration includes providing a housing with an opening, inserting a bushing assembly into the opening, and securing the cable bushing.
