Conception

The conception of a new propeller starts from the specification. For a customised propeller, this is provided by the customer; for a standard propeller the specification is established in collaboration with our engine-manufacturing partners.

Starting from the engine data, our propeller design software enables us to define the aerodynamic and structural characteristics of the propeller, and provides a 3D definition file of the propeller compatible with most CAD software.
Manufacture

From the 3D definition file we develop the CNC command files which shape the blades, or form the mould for carbon blades.

Wood composite blades are cut on our 12-headed CNC, ensuring a high production rate. Metal and carbon propellers are made by our partners who specialise in aircraft components as sub-contractors to companies such as Airbus.
Finishing and inspection

After the blades have been shaped, they are sanded and balanced by craftsmen who have over 10 years experience in this work.

Depending on the material used and the intended purpose, various finishing treatments are applied, such as reinforcement by glass-fibre layers, anti-UV, erosion or abrasion protective coverings, anodisation etc.

The propellers are balanced at each stage of the finishing process.

Inspection tools specially developed for this purpose ensure that the propellers conform to specification.
