Active surface structures comprise an exposed surface, a controlled group of MEMS (micro-electro-mechanical system) actuators, and a controlled region of the exposed surface corresponding to the controlled group. The controlled region has a first state, and a second state that is less textured than the first state. Active surface structures may be part of an apparatus that includes a controller and/or one or more sensors. The controller, sensors, and the controlled region may form a feedback loop in which the active surface structure is actively controlled.

Actively controlled surfaces

Active superhydrophobic surface structures are actively-controlled surface structures exhibiting a superhydrophobic state and an ordinary state. Active superhydrophobic surface structures comprise an outer elastomeric covering defining an exposed surface, a controlled group of MEMS (micro-electro-mechanical system) actuators at least covered by the elastomeric covering, and, a controlled region of the exposed surface corresponding to the controlled group. The controlled region has a superhydrophobic state in which the controlled region is textured. The controlled region also has an ordinary state in which the controlled region is smooth (i.e., less textured than in the superhydrophobic state). Active superhydrophobic surface structures may be part of an apparatus that includes a controller and/or one or more sensors. The controller, sensors, and the controlled region may form a feedback loop in which the active superhydrophobic surface is actively controlled.

A system for determining an optimal clocking orientation of an object at which to attach mating structure to the object includes a plurality of radiation devices, a plurality of transceivers, and a processor. The radiation devices are mounted on the object which has an as-designed object configuration. The transceivers are configured to generate distance measurements between the transceivers and the radiation devices at different clocking orientations of the object. The processor is configured to determine, based on the distance measurements, as-built object configurations corresponding to the different clocking orientations of the object. The processor is configured to compare the as-built object configurations to the as-designed object configuration and determines an optimal clocking orientation at which the as-built object configuration has the smallest deviation from the as-designed object configuration.

System and method for determining an optimal clocking orientation of an object

A system for determining an optimal clocking orientation of an object at which to attach mating structure to the object includes a plurality of radiation devices mounted on an object, a plurality of transceivers configured to emit radiation toward the object, and a processor. The object potentially has a first as-built object configuration that differs from an as-designed object configuration. The transceivers continuously generate distance measurements between the transceivers and the radiation devices during rotation of the object. The processor continuously determines, based on the distance measurements, additional unique as-built object configurations corresponding to changing clocking orientations of the object during rotation. In addition, the processor continuously compares the first and the additional as-built object configurations to the as-designed object configuration and, after completion of the rotation of the object through at least a portion of one revolution, determines an optimal clocking orientation at which the as-built object configuration has the smallest deviation from the as-designed object configuration.

Dynamic dimensional measurement system

Methods and systems for monitoring an integrity of electrical connectivity between a repair patch and a parent structure include providing the repair patch with an embedded sensor configured to detect electrical conductivity. The repair patch includes a ply of conductive material that overlaps a portion of a conductive layer of the parent structure. A baseline set of sensor data is acquired from the sensor indicative of an electrical connectivity between the ply of conductive material of the repair patch and the conductive layer of the parent structure. One or more additional sets of data may be obtained from the sensor and compared to the baseline set of data to determine an integrity of the electrical connectivity between the ply of conductive material of the repair patch and the conductive layer of the parent structure.

Detection and assessment of damage to composite structure

An edge stabilizer for a composite structure includes an elongate edge support segment, defining a geometric shape of an edge of the composite structure, and a connector, configured to attach the edge support segment to the edge of the composite structure. The edge support segment comprises first and second halves configured to attach together around the edge, each half including a shoulder, opposing mating relationship of the shoulders defining a slot for receiving the edge. The edge stabilizer can be part of a system for stabilizing an edge of a composite barrel section. The system can also include a moveable cart, the barrel section being supportable upon the cart.

An apparatus and method for installation of a frame assembly to a body may include a tooling assembly configured to support a frame assembly, the tooling assembly being positioned with respect to a body, wherein the frame assembly is positioned with respect to the body at a plurality of predetermined engineering locations.

A method and system for monitoring a mandrel. A first plurality of transmitting devices is positioned with respect to the mandrel. Signals from a portion of the first plurality of transmitting devices are received at a receiving device. The signals are processed to determine a configuration of the mandrel.

Mandrel configuration monitoring system

A barrel assembly for a composite structure includes a barrel of composite material, a first end ring, and a mid support. The barrel of composite material has a first end, an interior surface and an outer surface, and the first end ring is removably attached to the first end. The first end ring has a perimeter that is substantially congruent with the first end, and is configured to maintain a shape of the barrel. The mid support is removably disposed within the barrel, and has a plurality of spokes extending outwardly from a central hub to contact the interior surface, to maintain a shape of the barrel.
