A computer-implemented method for designing a pin joint having a bearing member and a pin member received within the bearing member is provided. The method includes receiving, via a Graphical User Interface (GUI), at least one input related to one or more pin joint configuration parameters. The method includes receiving, via the GUI, at least one input related to one or more pin member design parameters. The method includes receiving, via the GUI, at least one input related to one or more bearing member design parameters. The method includes calculating a set of design parameters of the pin joint based on the inputs related to the pin joint configuration parameters, the pin member design parameters, and the bearing member design parameters. The method includes generating an output design of the pin joint based on the comparison between the calculated set of design parameters with a set of predefined design parameters.

A retaining assembly secures an equipment item within an aircraft galley compartment. The retaining assembly may include a turn button assembly including a turn button connected to a front edge of the galley compartment to secure the equipment item within the galley compartment. The turn button rotates between a first position for allowing insertion or release of the equipment item from the galley compartment and a second position for securing the equipment item within the galley compartment. A turn button recess on an inner surface of a panel door that is coupled to an edge of an opening for the galley compartment receives the turn button of the turn button assembly when the turn button is in the second position to allow the panel door to fully close over the opening for the galley compartment.

A fracture-resistant double shear joint including a clevis having a first end defining a first bore and a second end defining a second bore, and a reaction load member defining a third bore, wherein the first bore, the second bore, and the third bore are colinear. The fracture-resistant double shear joint can further include a first spacer positioned within the first bore, a second spacer positioned within the second bore, and a shear pin positioned within each of the first bore, the second bore, and the third bore. The shear pin may include an outer cylinder, an inner shear bolt threaded on both ends, and nuts at either end that engage the threads. The nuts may be tightened to place the outer cylinder in compression. The spacers in the first and second bore may include a low friction liner that interfaces with the outer cylinder of the shear pin. The ends of the spacers may be set back from the ends of the first and second bores (that are next to the third bore).

A hinge assembly such as a lead-lag hinge can include a hinge pin assembly. The hinge pin assembly can include an outer cylinder, a shear pin that extends through the outer cylinder and having a first threaded end and a second threaded end, a first nut threaded on the first threaded end and a second nut threaded on the second end. An opposing force between the first nut and the second nut applies a compressive stress to the outer cylinder that may increase a resistance of the hinge pin assembly to wear and damage. In the case of complete failure of the outer cylinder, the shear pin can maintain structural integrity of the hinge pin assembly and of the hinge assembly.

A rail for a cable tray having opposite longitudinal ends includes a generally vertical web having opposite upper and lower ends, an upper flange at the upper end of the web, and a lower flange at the lower end of the web. A splice plate retention groove outboard of the vertical web and generally adjacent at least one of the opposite longitudinal ends of the rail is configured to receive a splice plate therein to facilitate positioning of the splice plate on the rail.

A fastener assembly includes a plunger, a grommet, and a lever arm. The plunger may include a head, a tip portion, and a longitudinal centerline axis. The grommet may be configured to receive the tip portion of the plunger. The tip portion of the plunger may be axially movable relative to the grommet between a latched state and an unlatched state. The lever arm may be coupled to the plunger between the head and the tip portion. The lever arm extends from the plunger at an angle relative to the longitudinal centerline axis, with the lever arm being actuatable to switch the fastener assembly from the latched state to the unlatched state, according to various embodiments.

A structural supporting bearing is comprised of a flange with a hole in the center and a cylindrical hollow tube. The cylindrical tube section is inserted through an appropriately sized hole in hollow fiberglass plastic tubing. The flange creates a stop for the cylinder against the outer wall of the tube. The length of the cylindrical tube is sized to approximately one-half the cross-section of the tube, so as to allow a similar bearing to be mounted to the other side of the tube. A plurality of other structural members is placed over the flanges as desired. The aforementioned assembly is configured to receive a suitably sized bolt through it and be secured in place with a receiving nut.

In an illustrative embodiment, an aircraft galley ducting assembly provides airflow to at least one compartment of an aircraft galley monument. The ducting assembly may include a supply air duct that provides a supply airflow path to a compartment that includes an inlet port mounted to a compartment surface. A return air duct may provide an exit airflow path for return air that has circulated throughout the compartment and includes an outlet port mounted to the compartment surface. An airflow adjustment apparatus with an airflow adjustment surface is positioned within the supply airflow path of the supply air duct or the exit airflow path of the return air duct to cause a modification of airflow properties for air passing across or through the airflow adjustment surface.

Wall blocks, veneers, veneer connectors, walls, and methods of constructing walls are provided. More particularly, the invention relates to constructing walls in which a veneer panel is attached to a wall block with a connector and in which the front faces of the veneers have a desirable texture.
