Abstract

Embodiments include a modular fuel pump apparatus for an aircraft refueling chassis and related devices, systems and methods. In one exemplary embodiment, a pump module includes a hydraulic motor driven by a hydraulic pump connected to a chassis motor. A chassis engine is operated at a substantially constant RPM, which causes the hydraulic pump to output hydraulic fluid to the pump module at a substantially constant hydraulic pressure. The speed of the hydraulic motor can be varied by a proportional flow control valve disposed between the hydraulic pump and the hydraulic motor, thereby varying the speed of the fuel pump and the flow rate of the fuel. A controller is configured to operate the pressure control valve such that the flow of the fuel is maintained at a predetermined flow rate.

Abstract

According to various embodiments, apparatuses and methods for providing a control system for aircraft refueling trucks is provided. The control system is configured for facilitating remote troubleshooting of one or more safety mechanisms associated with a flow of liquid fuel from a refueling vehicle to an aircraft, and analyzes data to determine whether one or more parameters associated with the one or more safety mechanisms have been satisfied. Once determined, the control system may generate a status for one or more selectable status indicators associated with the one or more safety mechanisms and display a visual representation of a particular safety mechanism associated with the selected status indicator The visual representation may include an image representing at least a physical location of the particular safety mechanism relative to the refueling truck so as to facilitate remote troubleshooting of the particular safety mechanism.
