“The
power
of digital tools
and methodologies developed
internally in this area contributes
to the technological expertise
of LISI AEROSPACE”
The Pylon Front Secondary Structure
for the Airbus A330neo
is a structural element located at the junction
of the engine nacelle and pylon of the aircraft.
The manufacturing tools of this subassembly,
developed in Argenton-sur-Creuse, were designed
using numerical simulation tools.
Shortening production tooling development
The pre-series of this highly technical subset, located at the
junction between the nacelle of the aircraft and the pylon (which
connects the engine and the wing), were produced following a very
tight development schedule in 2016 on LISI AEROSPACE’s site
at Argenton-sur-Creuse. Numerical simulation tools developed
over several years within the division were implemented for the
first time to develop the tooling necessary for the production of
this subset consisting of complex geometry skins, stiffeners and
assembly fittings made of hard materials. This new approach
combining our historical expertise with digital tools allowed us to
meet our schedule by avoiding long and costly iterations.
A team in project mode
Amultidisciplinary team, bringing together specialists in stamping,
tooling design and experts in numerical simulation, was set up
in project mode to develop this new tooling design approach.
By sharing expertise and using numerical simulation, the team
was able to solve every technical and industrial challenge of this
assembly and meet the customer’s deadline. When several test
phases were previously necessary to develop such type of tooling,
this pylon structure tooling was completed right the first time.
The power of digital tools and methodologies developed internally
in this area contributes to the technological expertise of LISI
AEROSPACE to develop such structures. This new approach
makes it possible, as part of a vertical integration approach, to
achieve considerable logistical and economic savings, for the
benefit of the division’s major customers, making a difference
today on that type of market.
