Abstract: A system for manufacturing a thermoplastic object may include a robotic arm configured to dispense thermoplastic material, a support apparatus, a computing device and an imaging system. The imaging system may scan thermoplastic material dispensed by the first robotic arm and create a three-dimensional scan model. The model may be compared to a computer model profile to determine if the dispensed material requires adjustment. If the dispensed material requires adjustment, the computing device may adjust the robotic arm or the support apparatus.

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: A radome structure for a multilayered broadband radome structure is described. The radome structure may include a central core layer comprising a first dielectric constant, an interior intermediate core layer adjacent to an interior side of the central core layer, comprising a second dielectric constant less than the first dielectric constant, an exterior intermediate core layer adjacent to an exterior side of the central core layer, comprising a third dielectric constant less than the first dielectric constant, and an interior outside core layer adjacent to an interior side of the interior intermediate core layer, comprising a fourth dielectric constant less than the second dielectric constant. In some examples of the radome structure described above may further include an exterior outside core layer adjacent to an exterior side of the exterior intermediate core layer, comprising a low dielectric constant.

Abstract: This patent document relates to systems, structures, devices, and fabrication processes for ceramic matrix composites suitable for use in a nuclear reactor environment and other applications requiring materials that can withstand high temperatures and/or highly corrosive environments. In one exemplary aspect, a method of joining and sealing ceramic structures is disclosed. The method comprises forming a joint of a ceramic structure and an end plug using a sealing material, wherein the end plug has a hole that goes through a top surface and a bottom surface of the end plug; filling the ceramic structure with a desired gas composition through the hole; heating a material into a molten form using a heat source; and directing the material into the hole, wherein the material solidifies to seal the end plug.

Abstract: 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.

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: Magnetic antenna techniques and devices are disclosed for operating at an RF or microwave frequency by using a magnetic antenna structure having a spatially varying property that varies spatially from one location to another location in at least a portion of the magnetic antenna structure. Such a spatially varying property can be reflected in various ways, e.g., a spatially varying geometry profile in part of or the entirety of the magnetic antenna structure, a spatially varying antenna material property in a spatially uniform geometry or a spatially varying geometry. The disclosed technology also provides magnetic antenna structures based on splitting the componentry for transmission and reception so that each can be individually optimized.
