Filed:

Aug 10, 2021

Appl. No.:

17/398459

Inventors:

- Bethesda MD, US
Jeffrey T. Drewett - Kennedale TX, US
David Haynes Coleman - Fort Worth TX, US
Daniel John Flanagan - Fort Worth TX, US
Steven E. Twaddle - Aledo TX, US

International Classification:

B23K 26/402
B23K 26/12
B23K 26/035

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.

David Haynes Coleman - Fort Worth TX, US
Stuart C. Street - Aledo TX, US
Steven E. Twaddle - Aledo TX, US

International Classification:

B08B 1/04

Abstract:

A system includes an abrasion component containing an abrasion pad configured to clean a faying surface of a nutplate and a shaft attached to the abrasion pad and configured to rotate the shaft and the abrasion pad during cleaning of the nutplate, which includes abrading the faying surface with the abrasion pad. The system further includes a base configured to attach to a pressure applicator, and the pressure applicator, which is configured to attach to the base, hold the nutplate such that the faying surface is capable of contacting the abrasion pad during the cleaning of the nutplate, and apply pressure to the nutplate such that the nutplate contacts the abrasion pad during the cleaning of the nutplate. Furthermore, the abrasion component is configured to rotate the abrasion pad within at least one of the base and the pressure applicator during the cleaning of the nutplate.

International Classification:

F16B 37/04
B24B 41/047
B24B 41/06

Abstract:

A system includes an abrasion assembly containing one or more abrasion pads configured to clean a faying surface of multiple nutplates, and a shaft attached to at least one of the abrasion pads and configured to rotate some or all of the abrasion pads during cleaning, wherein cleaning includes abrading the faying surfaces with the abrasion pads. The system also includes a base configured to attach to a pressure applicator, and a pressure applicator configured to attach to the base, hold the nutplates such that the faying surface of each nutplate is capable of contacting one of the abrasion pads, and apply pressure to the nutplates such that each of the nutplates contact one of the abrasion pads during the cleaning. Furthermore, the abrasion assembly is configured to rotate the abrasion pads within at least one of the base and the pressure applicator during cleaning.
