LuFo VI-3: AirTiMe – Project Number 20A2201B
Due to the high wing aspect ratio, particularly in the outer wing region, structural heights are significantly reduced. These low structural heights lead to situations where standard rivet spacing for connecting slats to their kinematics can no longer be maintained.
Therefore, IMA has set the goal of developing certifiable bonded joints. The integration of crack-stopping elements made of ductile materials serves to divide the bonded area into two separate load paths. In addition to coupon testing, detailed modeling provides the basis for demonstrating certifiability.
Beyond the attachment of the kinematics to the slat structure, the kinematic system itself poses significant challenges. Due to the low structural heights, existing and proven kinematic concepts cannot be applied.
To support Airbus in its development efforts, IMA aims to test a high-lift system for the wing leading edge on a ground-based test rig.
