The E-Props propellers are fully made in France, in the E-Props workshops, in Provence. The 1700 m² worshops are equiped with 12 CNC machining centers. The company has developed more than 140 propellers models (2017-12-16).


E-Props propellers CARBON range are designed and manufactured to be very light and strong. Materials and manufacturing process have been validated by many tests.

- made in carbon braid, with continue fibers between upper and lower surfaces of the blade

- epoxy resin

- foam core with internal spar (D-Box)

- blade's foot with titanium ring inside

- 100% carbon, no metallic part = no galvanic corrosion

- internal shielding of the blades : injection at the leading edge of a special resin with Nanostrength® (ARKEMA product : high kinetic energy absorption capacity) => See the page LEADING EDGE PROTECTION

- the epoxy resin is including a high resistance to UV additive (UVA and UVB). Blades are polished with a perfect finition.

- unique ref number on each blade for traceability (RFID chip inside)


The HCF (Helical Continuous Fibers) process, specifically designed by E-PROPS, ensures an exceptional strength of the 100% carbone + epoxy resin blade, from leading edge to trailing edge, from blade's foot to tip.

Blades and Hub : RTM (Resin Transfer Molding) manufacturing. This process is used by Airbus for some critical carbon parts on the liner aircraft. It is realized by following a strict cycle of temperatures. The baking of carbon parts allows to improve certain properties, in particular mechanical and of resistance under hot conditions (carbon hubs : max T° resistance = 120°C for reduced engines and 170°C for direct drive engines).

The workshop has two rooms : a medium-temperature / small steam room capacity and a high-temperature / big steam room capacity, both managed by computer.

To assure a strict quality control and the reproducibility of the production, the components are exactly weighed very throughout the manufacturing. 15 weighings are necessary for a propeller for Ultralights / Aircraft.


E-PROPS ensures the production monitoring by RFID and KANBAN method. These methods and tools optimize the manufacturing quality, reassure and fluidify the supplies, allow the real-time follow-up of the production process, the traceability of all the manufacturing steps, and offer a set of successful and reliable indicators.




E-PROPS : production monitoring by RFID and KANBAN



The company is using 12 CNC machining centres, including one innovative custom-made 8-axis centre with laser scanner and a professional 3D printer.

- Centrifugal load test of a carbon E-Props propeller (propeller for direct drive engine)

Results : safety coefficient = 7,2. The system carbon hub + blade can hold 6 times the maximal load during 1 hour without any damages (EASA CS-P asks only 2 times for certified propellers).
