Abstract: A thermal management system includes a closed-circuit refrigerant system to circulate a refrigerant fluid. The system includes a compressor to compress a flow of the refrigerant fluid. The system includes a condenser coupled to the compressor. The system includes a receiver to store at least a portion of the refrigerant fluid. The receiver is coupled to the condenser. The system includes a pump to circulate the refrigerant fluid through at least a portion of the system. The pump is coupled to the receiver. The system includes a flow control device to control the flow of the refrigerant fluid to an evaporator. The flow control device is coupled to the pump. The evaporator extracts heat from at least one heat load that is in thermal conductive or convective contact with the evaporator.

Abstract: A directed energy system includes a gimbal assembly that includes a turret configured to rotate about a first axis, and a directed energy head coupled to the turret and configured to rotate about a second axis that is orthogonal to the first axis. The system further includes an optical fiber spooling ring comprised of a fiber cable at least partially threaded through the gimbal assembly and including a plurality of optical fibers configured to transmit optical energy. The optical fiber spooling ring includes a plurality of 360 degree rotations of the fiber cable.
