Abstract: An aircraft refueling system (10) includes a master controller (12), a fleet controller (14) in communication with the master controller, a platform controller (18) in communication with the fleet controller, and a fuel control system (16) in communication with the platform controller. Embodiments of an aircraft refueling system may include a primary pressure controller (20), a secondary pressure controller (22), a programmable logic controller (24), and a data logger controller (26). The master controller may be configured to receive and analyze data from at least one of the fleet controller, the platform controller, and the fuel control system; and to modify operational parameters or upgrade the fuel control system based at least in part on the analysis of received data.

Abstract: A coupling assembly (10) may include a first member (20) and a second member (40), a release sleeve (110) movably connected to the first member, a retainer sleeve (70), and a spring (100). The second member includes a second member flange (50). The spring may be configured to apply a spring force to the retainer sleeve. The spring force may biases the retainer sleeve into a positive engagement with the second member flange.

Abstract: A temperature monitoring system includes an enclosure, an external temperature sensor, and an internal temperature sensor. The enclosure may be explosion-proof, and may include a controller and an internal display disposed within the enclosure. The external temperature sensor may be configured to detect an outside temperature, and the internal temperature sensor may be configured to detect a temperature inside the enclosure. Upon the external temperature sensor and/or the internal temperature sensor detecting a temperature that meets or exceeds a set or specified value or limit, the system may be configured to implement an action or order. In an embodiment of the system, the system may be configured to stop fueling in the event that the external temperature sensor and/or the interior temperature sensor detect a temperature that meets or exceeds a certain temperature.

Abstract: A fluid coupler includes a housing with an inlet port and an outlet port, a piston disposed in the housing and configured to control fluid flow between the inlet port and the outlet port, and a piston retainer disposed in the housing. A piston may include at least one radially-extending support member, and the radially-extending support member may include an aperture. The at least one radially-extending support member may be substantially planar.
