LISI#OneSide:
assembly automation
Presented at the Paris Air Show in 2015, the OPTIBLIND™
fastener is in its industrial optimization phase. Designed for
automated assembly process called “One side” – the robot
acts outside the structure only – this new fastener meets the
cost reduction and increased production rates requirements
expressed by aircraft manufacturers. The OPTIBLIND™
fastener guarantees the same performance as current “dual
access” fasteners. LISI AEROSPACE’s efforts also focus on
industrial validation and optimization of assembly sequences.
The division has invested in its own development cell which
is based at KUKA Systems near Bordeaux. The ROBOID
project aims to measure the assembly gains from these new
technologies under real industrial conditions.
Gains / Benefits
- Automated or manual installation
- Replaces “dual access” fasteners
- Integrated control system
A new technology for lightning currents
conduction
The use of carbon composite materials in the structure of
new generation aircraft sets new constraints for lightning
strikes resistance. LISI AEROSPACE has developed since
2008 an initial technology for sleeved fasteners called
STL™, which is specially adapted to highly loaded areas with
restricted access. Our continued investment in the field has
allowed the emergence of alternative technologies for the
more accessible areas. A unique combination of coatings
on our interference-mounted fastening systems PULL-IN™
/ PULL-STEM™ allows us to maintain good conductivity
of the assembly while improving the friction coefficient,
which facilitates installation in the structure. The A350
wing junctions are now fitted with fasteners designed with
“HI-KOTE™ coating stripes” technology, qualified with Airbus
in 2016. Several other applications of this technology are
under study with our aircraft manufacturer customers.
Gains / Benefits
- Conductivity / Evacuation of lightning currents
- Secure interference installation
- Weight and cost savings compared with sleeved fasteners
