Our teams offer a top-of-the-range, tailor-made service to support you in your projects according to your specifications (pleasure, workboat and defence vessels…) to exceed performance requirements. SDS drives are designed and manufactured in Cannes France.

FIRST STEP : TECHNICAL STUDY AND FEASIBILITY

On-site engineering, R&D department

Our engineers and designers integrate the specifications provided by our customers in order to propose the SDS model adapted to the characteristics of the vessel and the performance to achieve.

We work closely with our customers, shipyards, engine manufacturers and international naval architects on each case for the best solution for the implementation of the SDS on the ship.

Our engineering department is equipped with the latest CFD, CAD, CAD and CAM softwares.

The constant effort in research and development by FRANCE HELICES has improved the efficiency of the surface propellers up to 10% during the last decade. The surface piercing propeller FH5SSP model shows an efficiency above 75% in cavitation tunnel tests.

Once the SDS model is confirmed, we start assembling the SDS and manufacturing the surface piercing propeller. Every vessel has its own calculated propeller.

MAIN STEPS : PROPELLERS MANUFACTURING

Pattern making for casting

A state-of-the-art 3D printer allows us to manufacture these blade models on site according to the 3D patterns provided by the engineering department. This large-scale 3D printer is designed for high performance industrial application (up to 1m3). Every surface piercing propellers are custom made.

Foundry

These patterns are then used to create the moulds according to different techniques. We give a high priority to the quality of the selected metals to ensure endurance and optimal quality of your propulsion. A high-strength Nickel-Bronze-Aluminium alloy will then be casted into these moulds. Depending on the alloys, the metal is casted at casting temperatures ranging from 1200°C to 1600°C in our top quality partner foundries.

Machining on a 5-axis CNC milling machine

Our latest generation of digital Computer-Aided Manufacturing (CAM) tools increase productivity and the quality of the finished product. The numerical simulation of machining operations is integrated into the engineering department before production.

The surface piercing cast propellers are machined on our CNC milling machines with a high degree of accuracy to the nearest hundredth of a millimetre according to class S of ISO 484-2:2015.

Dynamic balancing

Dynamic balancing of the surface piercing propeller is done on the electronic balance according to ISO 484-2:2015, class S.
Dynamic balancing rotates the propeller to determine if a correction is necessary to eliminate any vibration and obtain a propeller that meets the required tolerances.

LAST STEPS : QUALITY CONTROL AND PACKING

Quality control carried out throughout the various manufacturing stages and in accordance with ISO 9001:2015, guarantee the end user optimal quality.
FRANCE HELICES controls and issues a final inspection by electronic pitchometer according to ISO 484-2:2015 class S standard.

Before being packed our SDS are systematically tested on a test bench for a last quality control.

Our propulsion systems can be certified by the main classification societies: Lloyds, RINA, BV, ABS, CCS…

International shipment

Our SDS drives and surface piercing propellers packaging crates are compliant with NIMP15 norm.
Transport is determined according to your needs (air, boat, train, road).
