摘要： A spark containment cap for forming a sealed cavity around an end of a fastener protruding from a structure is disclosed having a cap body with an annular base terminating at a rim which surrounds an opening into an air cavity arranged to enclose the end of the fastener. An annular sealing volume extends around the rim arranged to receive an annular bead of a curable sealing material around the opening into the cavity to provide a seal between the cap body and the structure to seal a volume of gas within the cavity. An engaging feature is configured to engage with the end of the fastener to prevent rotation of the fastener relative to the cap when the end of the fastener is received by the cap. A fastening system, a joint, an aircraft and a method of securing a fastener and a spark containment cap to a structure are also disclosed.

摘要： A method of joining a first workpiece to a second workpiece is disclosed including securing a spark containment cap to the first workpiece, the cap comprising an electrically insulating washer and a cap body defining an air cavity. Once the cap has been secured, a tail of a fastener is inserted into the air cavity through the second workpiece, the first workpiece and the washer. Upon tightening the fastener, the tail of the fastener urges the washer against the first workpiece and the first and second workpiece are thereby clamped between the washer and a head of the fastener so as to form a joint. Advantageously, it has been found that forming a joint in this manner can help to better protect the joint from the effects of electrical arcing.

摘要： A fastener assembly includes a bolt having a head and having a shank. The shank defines threads, the bolt defines a channel which extends circumferentially about the bolt, and the head defines multiple head channels with a first end of each of the multiple head channels in communication with the channel and a second end of each of the multiple head channels in communication with an outside of the head positioned at a top surface of the head. The fastener assembly further includes a sleeve having threads compatible for engaging the threads of the bolt. The sleeve includes a portion of the sleeve including an annealed material and multiple slots defined through the sleeve. With the bolt positioned within the sleeve, each of the multiple slots defined through the sleeve is positioned in communication with the channel.

摘要： A system includes a fuel level sensing probe inside a fuel tank and an exciter wire bundle to connect the fuel level sensing probe to a power source outside the tank. The exciter wire bundle includes an excitation wire and a grounded guard wire. The excitation wire and the grounded guard wire each include a resistive non-metallic wire. The system also includes a return signal wire bundle to connect the fuel level sensing probe to a device configured to measure a quantity of fuel within the tank. The return signal wire bundle includes a return signal wire and a grounded guard wire. The grounded guard wire of the return signal wire bundle and the grounded guard wire of the exciter wire bundle are configured to shield the return signal wire from electromagnetic interference. The return signal wire and the grounded guard wire each include a resistive non-metallic wire.

摘要： A static eliminator (10) includes: a first conductor (11) that is electrically connected to at least a part of a static elimination target object (1); and a dielectric shell (15) that forms, between the first conductor and the dielectric shell, a first space (13) in which a gas (12) providing a condition of lowering a discharge starting voltage is sealed. The dielectric shell is exposed to an external space (9), as examples may be dome-shaped, spherical, ellipsoidal, or semi-ellipsoidal, and may be translucent.
