Abstract
This paper gives an outline of testing carried out in conjunction with Electroimpact to support the introduction of the A319/A320/A321 and A340-500/600 Panel Assembly Cells in Broughton, UK. Testing compared the percussion insert/EMR swaging of lockbolts with existing hydraulic installation methods. Tests included pre-load tension tests, ultimate tension load tests, tension fatigue tests, high-load lap shear fatigue tests, static lap shear tests, a pressure leak test, and metallurgical examination.
Fastener configurations tested covered diameters from 1/4, 5/16, 3/8, and 7/16 of an inch. Joint materials conformed to ABM3-1031 (7150-T651 plate), stump-type lockbolts to ABS0550VHK (Huck LGPS4SCV), and collars to ASNA2025 (Huck 3SLC-C). Some pull-type lockbolts to ABS0548VHK (Huck LGPL4SCV) were also tested as noted.
