Engineered into the material

The performance is not a coating or an add-on. It comes from the layup itself.

Ice forming on a monolithic carbon-fibre propeller blade in flight
Passive de-icing

Sheds ice. No added energy.

The smooth, low-porosity surface of monolithic carbon fibre limits ice adhesion. Frost forms, then sheds in flight. No heaters, no power draw.

Monolithic carbon fibre

No foam core. No delamination.

Zero moisture

No swelling, no performance loss.

Low acoustic signature

Tip speed under 0.55 Mach.

Thermal-optimised motors

Sustained high-load duty cycles.

One range, every mission

Select a mission to see the propulsion that fits it.

Agriculture

High endurance for large-area spraying.

Long flight times and steady thrust keep coverage rates high across hectares of crop, day after day.
