Description
HELIX propellers have been built since 1990 using composite materials such as carbon
fibre, epoxy-resin, epoxy resin foam and aluminium.
This combination of materials provides:
- High Thrust
- Low Noise
- Durability

2-blade and 3-blade propeller of type H30F
The propeller blades are made from several layers of woven carbon fibre, reinforced with
different sorts of carbon fibre tapes. They are bonded with epoxy resin foam reinforced
by glass fibre. This method of construction ensures that the load is distributed throughout
the whole surface of the blade and dissipates vibration.
