    Abstract: The disclosed technology can be implemented to provide a method of determining a thermal conductivity of a sample. The method includes controlling a thermal source to increase a temperature of the thermal source to an elevated temperature above a phase change temperature of a phase change material, placing the sample between and in thermal contact with the phase change material below the phase change temperature and the thermal source to allow a thermal conduction from the thermal source to the phase change material through the sample to increase an initial temperature of the phase change material to the phase change temperature to cause the phase change material to transition from a first phase to a second phase, performing a measurement on at least one of the sample or the phase change material, and determining the thermal conductivity of the sample based on the measurement.

    Abstract: The range of energy transmissions or bursts (e.g., the range of high power microwave (HPM) directed energy weapons) may be increased using multiple sources (e.g., multiple HPM sources). For instance, according to techniques described herein, the individual sources may be fired at precise times such that the electromagnetic pulses are efficiently generated by each source and accurately add waveform peaks on the target. One or more aspects of the described techniques achieve sub-nanosecond timing accuracy by placing an HPM source, ultra-stable clock, and a laser pulse detector on each HPM weapon platform. For instance, the array may be triggered by firing a laser pulse at the target from one platform. By timing the firing of each HPM source based upon when the reflected laser pulse arrives at each platform as measured by the clock, the HPM pulses may arrive on target more accurately (e.g., more simultaneously).

    Abstract: Fuel isolation systems, apparatuses and methods are described. In some embodiments, a system comprises a fuel tank, a fuel pump, an engine, a firewall, a fuel line from the fuel tank to the engine, a connector coupled inline with the fuel line on a cold side of the fuel line, a normally closed valve coupled to the connector, an air feed line coupled to an ullage of the fuel tank and to the valve. In the event of an engine fire condition, a control unit outputs signaling to turn off the fuel pump and open the valve to introduce air from the ullage into the fuel line. The introduced air provides a siphon break in the fuel line such that the fuel cannot be siphoned and the only fuel that can pass the firewall is the remaining fuel in the fuel line downstream of the connector and the introduced air.

    Abstract: Features for in-flight recovery of an unmanned aerial vehicle (UAV). A towline may be deployed by a host aircraft in-flight in order to recover a target UAV that is also in-flight. A reel on the host aircraft may pay out the towline having a fitting thereon. A catch on the target UAV may engage with the fitting on the towline, and the reel may then retract the towline to thereby pull in the target UAV to the host aircraft. The target UAV may then securely attach with the host aircraft.
