Abstract: The present disclosure relates to a coherent aperture array system for steering an optical source beam. The system may have a plurality of spaced apart, steerable emitters each being able to be mechanically aimed at a remote target location to steer portions of the source beam toward the target location. Each steerable emitter has a subaperture controllable independently of a remaining reflective surface of its associated steerable emitter, to receive and reflect a subportion of the source beam portion. The subportion forms a sense beam which is reflected toward a phase imaging system. A separate reference beam is created from the portion of the source beam travelling toward each steerable emitter. Each sense beam and each reference beam are thus associated uniquely with one of the steerable emitters. A phase imaging system is responsive to each of the reference beams and the sense beams, and determines phase differences between the portions of the source beam being transmitted from each steerable emitter.

Abstract: Fuel rod designs and techniques are provided to encapsulate nuclear fuel pellets in nuclear fuel rods. The tubular cladding in the disclosed fuel rods includes silicon carbide and a metal filler structure formed of a metal that becomes molten during a nuclear reaction of the nuclear fuel pellets and located inside the tubular cladding to include a metal tube that fills in a gap between the nuclear fuel pellets and an interior side wall of the tubular cladding and structured to include a closed metal end cap at one end of the nuclear fuel pellets to leave a space between one end of the interior of the tubular cladding and the closed metal end cap of the metal filler structure as a reservoir.

Abstract: Systems and methods are described for a satellite control system that exhibits improved stability and increased efficiency by implementing a non-linear dynamic inversion inner-loop control algorithm coupled with an eigen vector outer-loop control algorithm. Thus, the attitude determination and control system (ADACS) may operate using commands to rotate directly about an eigen vector. Additionally, the outer-loop control system includes a feed-forward control element to enhance pointing accuracy when tracking moving targets.

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: 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: 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 are disclosed. In one aspect, a ceramic composite structure is provided. The structure comprises a chamber including an external shell and a hollow space inside the external shell. The external shell includes an inner composite layer including a first composite structure, a middle composite layer placed outside of the inner composite layer, the middle composite layer including a second composite structure that is different from the first composite structure, and an outer monolithic layer that has a spatially uniform material property and placed outside of the middle composite layer.

Abstract: Magnetic antenna techniques and devices are disclosed for operating at an RF or microwave frequency by using a magnetic antenna structure that is configured to have 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 spatial varying property can be reflected in various ways, e.g., a resonator located in part of the magnetic antenna structure, or a spatially varying geometry profile in part of or the entirety of the magnetic antenna structure.

Abstract: An energy efficient and lighter-than-air high altitude platform (HAP) is disclosed that allows for sustained station keeping at high altitudes of about 50,000-80,000 feet for prolonged periods of time. The HAP includes an aerodynamically streamlined body that may have the topology of a torus. The body may be inflated with a lighter-than-air gas in an amount sufficient to provide lift to the high altitudes. The HAP has a duct extending through the pressurized body that diverts flow through the duct and reduces aerodynamic drag. The HAP may include one or more propellers situated in the duct to provide propulsion and maintain a given location of the HAP relative to ground. There may also be a control system, a solar energy collection system, an energy storage system, and/or any of a variety of payloads to accomplish various tasks, such as communication and/or situational awareness applications.
