Abstract: A wind estimation system for an aircraft includes a first sensor configured to sense a first position associated with an aircraft control component in a wind condition, a second sensor configured to sense a first configuration associated with a rotor system of the aircraft in the wind condition, and at least one controller in communication with at least one of the first sensor or the second sensor. The at least one controller is configured to determine a tip-path-plane angle of the aircraft based on the first position and the first configuration, and determine at least one of a current wind speed or current wind direction based on the tip-path-plane angle.

Abstract: Provided herein are various enhancements for waveguide structures used in radio frequency feed components. In one example, an apparatus includes a septum polarizer having first feed ports and a common port, a high-pass filter coupled to the common port of the septum polarizer, and a multi-port orthomode transducer (OMT) coupled to the high-pass filter and providing an antenna port. The apparatus also includes hybrid couplers coupled to low-pass filters fed from the multi-port OMT, and magic tee elements cross-coupled to the hybrid couplers and providing second feed ports.

Abstract: Provided herein are various enhanced systems, apparatuses, and techniques for optical communication among a constellation of satellites. One example includes establishing an initial cross-connect configuration comprising optical communication links among a constellation of satellites. In the initial cross-connect configuration, the satellites can optically communicate with both adjacently positioned and non-adjacently positioned satellites in the constellation. The satellites obtain angular states of the optical communication links resultant from orbital motion of the satellites. When angular states of a portion of the optical communication links reach an exclusion range, the satellites establish a subsequent cross-connect configuration to avoid optically communicating within the exclusion range.

Abstract: A system includes a first structure having an upper surface coupled to a second structure by a fastener assembly including a bushing positioned within an opening in the upper surface of the first structure. An inner opening of the bushing defines an inner diameter, and a fastener is at least partially positioned within the bushing. An outer surface of the fastener defines an outer diameter of the fastener. The bushing and the fastener are configured such that a space between the outer surface of the fastener and the inner opening of the bushing defines a gap which increases in size in a direction extending from the upper surface to the lower surface of the first structure.

Abstract: Technology is disclosed herein to generate an indication of a potential that a lightning event will result in ignition based on satellite data. In an implementation, a computing system obtains data associated with a lightning event. The data includes a location of the lightning event and one or more measurements of the lightning event captured by a sensor. The computing system identifies characteristics of the lightning event based at least on the one or more measurements. The computing system predicts the ignition potential of the lightning event based at least on the lightning characteristics and the fuels characteristics.

Abstract: According to an embodiment, a method includes removing a last feed forward layer from a pre-trained neural network. The method further includes appending the pre-trained neural network with a secondary last feed forward layer configured to output a plurality of parameters. The method further includes updating each one of the plurality of parameters by: 1) multiplying each one of the plurality of parameters by a first factor to produce a plurality of resultant parameters; and 2) adding a second term to each one of the plurality of resultant parameters, wherein both the first factor and the second term vary due to backpropagation. The method further includes using a loss function to determine the distance between a known class embedding and an input from an input dataset. Lastly, the method includes updating one or more weights associated with the number of variables in the pre-trained neural network.

Abstract: A system includes a robotic arm, a rotisserie control linkage, and a computer system. The robotic arm includes a touch probe and laser head. The rotisserie control linkage is configured to couple to a transport cart. The computer system is communicatively coupled to the robotic arm and the rotisserie control linkage and is configured to control the system to probe, using the touch probe of the robotic arm, a transparent outer layer of an aircraft canopy located on the transport cart in order to determine surface measurements of the aircraft canopy. The computer system also controls the system to ablate, using a plurality of predetermined parameters and the laser head of the robotic arm, an interface layer located between the transparent outer layer and the aircraft canopy, wherein movements of the robotic arm during the ablation are based on the surface measurements.

Abstract: A rotor blade includes a spar with forward end, an aft end, and a substantially oval cross-section. The cross-section includes an upper portion tapering from a first thickness to a smaller, second thickness beginning between about 55% and about 65% of the distance to the aft end from the forward end and ending between about 65% and about 75% of the distance to the aft end measured from the forward end, and a lower portion tapering from a third thickness to a smaller, fourth thickness beginning between about 55% and about 65% of the distance to the aft end from the forward end and ending between about 65% and about 75% of the distance to the aft end measured from the forward end. The rotor blade further includes an upper blade skin, a lower blade skin, and a leading edge sheath.
