P.A.S.S. – Piezo Anti-Ice Smart Skin for Composite Aircraft Wings
A lightweight, low-power de-icing and anti-ice solution for unmanned composite aircraft.
P.A.S.S. – Advanced De-Icing for Composite UAVs
The P.A.S.S. system is a next-generation MFC-based de-icing and anti-icing solution designed specifically for unmanned aircraft with composite leading edges. Engineered to be lightweight, low-power, and retrofittable, P.A.S.S. provides an efficient alternative to traditional de-icing methods.
With most modern UAVs built from full-composite materials, long-duration missions often require reliable ice detection and mitigation systems that won’t add excessive weight or energy consumption. Unlike conventional de-icing systems that rely on heat or strong mechanical forces, P.A.S.S. prevents ice buildup without compromising structural integrity. This is achieved by seamlessly integrating Smart Material’s Macro Fiber Composites (MFCs) into the composite laminate, eliminating the risk of thermal stress or material fatigue.
Key Advantages of P.A.S.S.
PASS has been tested extensively in ice tunnels during the past years and has currently a TRL8 status.
Proven Reliability
Successfully tested in extreme conditions (-20°F, 180 knots) for dependable ice protection.
Lightweight Design
Adds minimal weight (0.3 lbs per linear foot), preserving aircraft efficiency and performance.
Energy-Efficient
Requires only 1.6 W/ft in anti-ice mode, reducing power consumption for long-duration missions.
Long-Lasting Durability
Withstands 1,500+ flight hours in icy conditions, ensuring longevity and reliability.
Continuous Protection
Anti-ice mode can remain active throughout the entire mission, providing uninterrupted ice prevention.

MFC P2 and P3 type
d31 effect – Contractor
P2 and P3 MFCs use d31 effect for actuation and contract up to 750ppm when operated at the maximum voltage rate of -60V to +360V. Both P2 and P3 MFCs are most commonly used for energy harvesting (PEH) and as strain sensors.
MFC Custom Design
In addition to manufacturing Macro Fiber Composite™ in a variety of standard sizes, we also offer numerous specialized MFC layouts. Specialty MFCs have more complex designs, including arrays of single MFCs, and also allow electronic components to be integrated with the MFC.
