Films and Coatings for Lightning Strike Protection
LORD Corporation Copyright 2012
Fly lighter, manufacture with less.
16. UltraConductive Performance
• Lightning Strike Tests: Passes Zone 1A and Zone 2A with no puncture of thin
gauge carbon fiber panels.
• Weight savings: Direct and indirect weight savings with areal weights of 140
gsm and 190 gsm requiring less paint surfacer weight as well.
• Surface Finish: Improved surface finish over heavier expanded metal foil
solutions
• Manufacturing: Improved throughput by reducing surfacing and “metallization”
joining steps required with expanded metal foils.
• EMI Shielding: Enables composites to approach shielding levels of aluminum
skin
• Secondary Properties: Equivalent or superior to expanded metal foil in tests
including: corrosion, wear resistance, paint adhesion, solvent resistance, UV
Resistance, thermal cycling and mechanical fatigue.

Modeling for Real-Time Flight Simulation
• Pilots are increasingly being trained
in simulators
• Current sims are excellent for normal
flight conditions, but not for stall and
post-stall
• Recent high-profile airliner accidents
provide strong impetus for flight sims
to be reliable for stall recovery
training
• Stall aero/flight models for real-time
calculation being developed at NC
State under NASA Langley funding
• PhD research of Ryan Paul (Advisor:
Dr. Gopalarathnam)
• Potential for training UAV pilots in off-
normal flight conditions and in
turbulence
