Lightning Strike Protection Material Assembly, System, and Method of Using the Same
There is provided a lightning strike protection material assembly including a lightning strike expanded metal foil layer with a lightning strike expanded metal foil, and including a resin infused scrim layer having a non-metallic scrim infused with an infused resin having a tailored viscosity and a tailored cure profile. The lightning strike protection material assembly is configured for laying up on, and co-curing with, an uncured composite laminate assembly having a plurality of structural ply layers preimpregnated with a structural resin. The structural resin has a structural resin viscosity and a structural resin cure profile that are different from the tailored viscosity and the tailored cure profile, to prevent mixing of the structural resin and the infused resin during co-curing, to allow the infused resin to effectively encapsulate the lightning strike expanded metal foil, and to provide a defined resin boundary. A cured lightning strike protection composite structure is formed.
There is provided a modified modulus composite laminate system including a composite laminate assembly having structural ply layers preimpregnated with a structural resin. The system includes a surface layer applied to the composite laminate assembly, and having a modified modulus less than, or equal to, a ply modulus, a surface layer coefficient of thermal expansion different from a ply coefficient of thermal expansion, and a surface layer coefficient of moisture expansion different from a ply coefficient of moisture expansion. The system has at least one secondary coating applied to the surface layer. The modified modulus of the surface layer is modified to be greater than, or equal to, a secondary coating modulus. The surface layer creates a stress relief and an integrated dampening between the secondary coating and the structural ply layers, to provide an increased microcracking resistance and a minimized structural degradation of the modified modulus composite laminate system.

An assembly that is operatively connected with a connection assembly to a turbine engine of an aircraft. The assembly includes an accessory gearbox with a body configured to be connected to the connection assembly and mounting pads spaced about the body. A first accessory is mounted to the body at a first one of the mounting pads. A second accessory is mounted to the first accessory with the first accessory and the second accessory in a stacked arrangement.
Techniques for identifying a fault in a circuit. These techniques include measuring at least one of a first voltage drop or a first resistance, across a first circuit, using a load tester providing a first load greater than zero, and measuring at least one of a second voltage drop or a second resistance, across the first circuit, using the load tester providing no load. The techniques further include determining that at least one of: (i) a difference between the first voltage drop and the second voltage drop, or (ii) a difference between the first resistance and the second resistance, exceeds a pre-determined threshold value, and, based on the determining, identifying a fault in the first circuit.

SYSTEM AND METHOD FOR DETECTING AND AVOIDING CONFLICTS ALONG A CURRENT ROUTE OF A VEHICLE
A system and method for detecting and avoiding a conflict along a current route of a vehicle is described. In some implementations, the system accesses or determines trajectories of the vehicle and a plurality of nearby moving objects, the trajectories being determined forward in time. Next, the system performs a comparison of the trajectories, and, predicts one or more conflicts between the vehicle and corresponding ones of the nearby moving objects. The system then determines the most-imminent conflict and selects a maneuver to avoid the most-imminent conflict. The system includes a user interface, where a specific resolution to the conflict is displayed. The specific resolution includes a direction in which to turn the vehicle and the magnitude of heading change. In some alternative implementations, the specific resolution is transmitted to a guidance system of the vehicle where the resolution is automatically executed by the guidance system.

The coating system comprises a first layer comprising a chemical blocker configured to prevent transmission of at least one of ultraviolet light or visible light within desired wavelengths, and a second layer thereover and in contact with the first layer and configured to reflect infrared components of sunlight. The second layer comprises a colorant configured to reflect the infrared components of sunlight, wherein the first layer is positioned between the second layer and the composite component.
A pose estimation system comprising a computer system and a pose estimator. The pose estimator is configured to estimate initial point cloud colors for points in a colored point cloud of a surface of an object using frames in a video of the object and initial pose estimates for the object in the frames; adjust the initial pose estimates using the frames and the colored point cloud to form updated pose estimates; and determine updated point cloud colors for the points in the colored point cloud using the frames in the video and the updated pose estimates. The pose estimator is configured to repeat adjusting the updated pose estimates using the frames and the colored point cloud and determining the updated point cloud colors for the points using the frames in the video and the updated pose estimates until the updated pose estimates meet a threshold.
A barrier system is configured for a cargo compartment of an aircraft. The barrier system includes a base configured to be supported on a floor of the cargo compartment. A divider wall extends upwardly from the base. A closeout membrane extends around one or more portions of the divider wall. The closeout membrane is configured to sealingly engage one or more portions of the cargo compartment. The barrier system is configured to be moved within the cargo compartment to provide an isolation zone within the cargo compartment.
The present disclosure provides a tool for tightening or loosening nuts (e.g., B-nuts that couple aircraft fuel lines). An apparatus includes a crowfoot, a clasp, and a first gear.
