Abstract: Described herein are aircraft, comprising rear spar integration assemblies, and methods of manufacturing these aircraft. Specifically, an aircraft comprises a keel beam and a center wing box, comprising a rear spar. The rear spar is attached to the keel beam using a rear spar integration assembly. The assembly comprises a rear spar stiffener, attached to the rear spar, and having a stiffener load axis. The assembly also comprises and a keel beam fitting, attached to the keel beam, and having a fitting load axis. The rear spar stiffener is also attached to the keel beam fitting, e.g., using splice plates. More specifically, the fitting load axis is offset relative to the stiffener load axis along the primary axis of the aircraft. This offset is designed to compensate for a bending moment at the keel beam-rear spar interface, which allows reducing the size and/or the number of fasteners needed.

Abstract: A drinking cup filter assembly for inhibiting a user's mouth from contacting a drinking cup includes a shield that has a first portion being spaced from a second portion to define a cup space between the first and second portions. The shield can be suspended on a lip of a drinking cup having the lip being positioned in the cup space. The first portion and the second portion inhibit a user's lips from contacting the drinking cup when the user drinks. The first portion has a plurality of fluid inlets and a fluid outlet to pass a beverage in the drinking cup through the fluid inlets and the fluid outlet. In this way the user can drink the beverage. A filter is removably positioned within the first portion of the shield to filter the beverage.
