Abstract: Apparatus, systems, and methods provide for a zero-moment fitting for securing a fluid conduit to a structure. According to various embodiments, a fitting may include a spherical bearing and a bearing housing. The spherical bearing may include a conduit aperture for receiving a fluid conduit through the spherical bearing. The bearing housing may be configured to encompass and retain the spherical bearing within the bearing housing, allowing for rotation of the spherical bearing within the bearing housing. The bearing housing may be fixedly attached to the structure to secure the fitting to the structure.

Abstract: A method, computer program, and system for generating computer-based models of seats on a passenger compartment floor plate from a first document are provided. According to an exemplary embodiment of the invention, a first document defining a plurality of seat positions and seat identities associated with the seat positions is received. Dimensions according to seat identities are extracted. A model of the seats affixed with fasteners to the passenger compartment floor plate based upon the seat positions, the extracted dimensions, and seat identities is generated. Loads on the fasteners generated by subjecting the model to an acceleration of a known magnitude and direction are simulated and stored.
