LISI 2016 ANNUAL REPORT
Fuselage insulation
blanket fasteners
LISI AEROSPACE’s research teams have developed new
fastener systems to maintain the insulation blankets installed
on the aircraft fuselage. These fasteners insure among other
functions blanket positioning during 5 minutes under extreme
circumstances to allow passenger evacuation in case of fire
from the outside of the aircraft. Developed on the basis of a
stamping technology mastered by the City of Industry site,
these new fasteners mounted on the new Chinese C919
aircraft (pending certification by COMAC), also provide
significant weight savings compared to systems already on
the market.
Gains / Benefits
- Resistance to fire requirements
- Weight saving
Composite polymers
clipnuts
LISI AEROSPACE is a leading supplier of clipnuts. They are
widely used in structure, systems and interiors of aircraft.
Previously offered in their metal versions, they are now
available in composite versions. The digital simulation skills
of LISI AEROSPACE applied to polymers were used to develop
a clipnut version made of TORLON™ nonmetallic materials
that can replace a variety of existing metal clips. These HPP™
(High Performance Polymer) clipnuts retain their performance
in the harshest environments (230°C/450°F). They also limit
the risk of damage to the aircraft structure at the time of
installation and allow standardization of references, enabling
our customers to maximize volumes and reduce their
inventories.
Gains / Benefits
- Weight saving
- Robust installation
- Protection of aircraft structure
