A two-piece, one-sided-installation fastener system may have an internally-threaded sleeve having a shank and a sleeve head. The fastener system may include an externally-threaded core bolt having a frangible driving provision and a core bolt head.

Method of installing a structural blind fastener

A fastener insertion system, for use with an assembly stack-up, includes a fastener and an end effector. The end effector includes a drill bit for drilling a hole through the stack-up, a probe for determining a stack-up parameter, and a fastener feed head for installing the fastener into the hole and applying rotational torque to complete fastener installation. The fastener insertion system also includes a processing device and an angle sensor communicatively coupled to the processing device and to the end effector. The processing device is programmed to measure, with the rotation angle sensor, the angular displacement required to complete fastener installation and to transmit a signal representative of the measured angular displacement from the angle sensor to the processing device. The processing device is also programmed to compare the measurement of angular displacement required to complete fastener installation to a range of angular displacement indicative of correct fastener installation.

Systems for in-process quality control during drill-fill assembly

An aircraft comprises a secondary support structure and a nut plate engaging the secondary support structure. The nut plate includes at least one locator protrusion engaging a mounting hole in the secondary support structure to constrain motion of the nut plate along the secondary support structure. The nut plate further includes means for additionally constraining motion of the nut plate away from the secondary support structure.

Structural blind fastener and method of installation

A fastener system for composite structure provides electromagnetic energy protection by incorporating a self-aligning head (SAH) fastener having a head with a spherical engaging surface and a shank extending from the head for insertion through a hole in a composite structure and a self-aligning self sealing (SASS) washer having a throat receiving the shank and a spherical mating surface interfacing with the spherical engaging surface of the head.

Self-aligning sleeved protruding head fasteners with electromagnetic effect protection features

An aircraft comprises a secondary support structure, and a nut plate engaging the secondary support structure. The nut plate includes at least one locator protrusion engaging a mounting hole in the secondary support structure to constrain motion of the nut plate along the secondary support structure. The nut plate further includes means for additionally constraining motion of the nut plate away from the secondary support structure.

A method for assembling a structure is described. The method includes locating a position in an assembly stack-up where a one-sided fastener is to be installed, drilling a hole through the assembly stack-up at the position, countersinking the hole to a specified depth, operating a calibrated probe to determine at least parameter associated with one or more of the hole and the stack-up proximate the hole, inserting the one-sided fastener into the hole, applying a rotational torque to the one-sided fastener to complete installation of the one-sided fastener, and comparing a measurement of angular displacement required to complete installation of the one-sided fastener to a range of angular displacement indicative of correct installation of the fastener.
