E-PROPS : Workshops and Production Means


E-PROPS's headquarters, research office and ultra-modern workshops are located on Sisteron airfield LFNS (town : Vaumeilh), North of Sisteron, Alpes de Haute Provence - exactly between Grenoble et Marseille, at an altitude of 535 m.
The industrial area has an access to the 1000 m runway.

eprops company workshops
All the buildings of the industrial zone (7000 sqm) belong to the company Hélices E-Props.

In the E-PROPS company, everything is thought and implemented to design and produce propellers with the smallest impact on the environment : ultra-light propellers and carbon parts, manufactured following an eco-responsible approach in energy-plus buildings (photovoltaic panels on the roofs, geothermal energy...).

You are welcome to visit our workshops !

1 - Present workshops : 3000 m²


Workshop 1 (1600 m²) :

eprops company workshops

- Different and dedicated workshops: propellers workshops, prototyping, mechanics, electronics for a production capacity of 75000 blades / year
- 12 machining centres, including an innovative 8-axis centre with laser scanner to analyze blades and hubs
- a high-temperature furnace and forming dies for Titanium leadinf edge protection
- 2 ovens medium temperature / small capacity and one oven high temperature / big capacity
- A lathe and a conventional milling machine
- Some welding systems
- Offices and meeting room

Workshop 2 (900 m²) :

Storage zone for airplanes

Workshop 3 (500 m²) :


eprops company workshops

- A fatigue tests bench, to stress the blade with alternating bending, to reproduce the engine's torque, and to establish the real propellers' potential
- A traction tests bench : 40 tonnes hydraulic cylinder. High : 3,5 m. Weight : 300 kg
- Other tests benchs, for many different mechanical tests.


2 - Workshops under construction : 4200 m²


In June 2021, Electravia was awarded the "France Relance" Plan - Territoires d'Industrie. A significant grant is being provided to the company to help rapidly build a new 4200 square meter smart and eco-responsible factory, including CNC machining centers, robots and additive manufacturing machines. These new workshops will enable the hiring of 35 new employees, bringing the company's workforce to 70. Within 3 years, the company plans to triple its current turnover and to increase its production from the current 45,000 carbon composite parts per year to over 150,000.

3 - Means of production


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.

eprops kanban

In July 2017, E-PROPS has implemented two new production equipment :
- a 8-axis machining centre to allow the dimensional analysis, the rectification and the finish of the carbon parts automatically, without dismantling of the part. It is equipped with a directional spindle programmed according to the digital definition of the part, with a wide tool store. The precision of measure by the scanner laser is of 5/100th of millimeter. The scanner sweeps the carbon part, the program recognizes it according to its database, then the different tools come to make all the finishing work: deburring, cut, drilling, sanding and polishing. All the stages between the molds and the stock are automatic. A robot arm presents the parts to the machining centre.


- a professional 3D printer, in order to realize equipments, molds, prototypes and of pre-series parts, as well as lighter functional components. This technology is going to allow E-PROPS to design and to make parts with complex geometries or aerodynamic properties difficult, even impossible, to make with traditional methods.

... that is the necessary means for conception, tests, manufacturing and marketing of E-Props propellers

4 - Localisation : Sisteron airfield


The company HELICES E-PROPS is located at the edge of the Sisteron - Vaumeilh airfield (LFNS), 10 minutes flight south of Gap-Tallard.
The grass runway is 1000 m long, with a 700 m acceleration strip.
This airfield, managed by the Gliding Club, is for restricted use. However, it is possible to land there without prior request to come and see the based companies (E-PROPS, restaurant): a permanent NOTAM authorizes access to aircraft without formalities.

NOTAM :
LFFA-D0092/22
Q) LFMM/QFAXX/IV/NBO/ A/000/999/4417N00556E005
A) LFNS SISTERON VAUMEILH
B) 2022 Jan 20 00:00 C) 2022 Jul 19 23:59
E) EXTENSION DE L'USAGE RESTREINT AUX AERONEFS UTILISANT LES SERVICES
DES ENTREPRISES SITUEES EN BORDURE DE L'AERODROME.
"EXTENSION OF RESTRICTED USE TO AIRCRAFT USING THE SERVICES OF COMPANIES LOCATED ON THE EDGE OF THE AIRFIELD"

It is therefore not necessary to contact the DGAC or the airfield manager before landing. Just check that the NOTAM is active.
In case of possible radio contacts, specify that you come to see E-PROPS.
For propeller assemblies or controls, come directly to the front of the ELECTRAVIA - E-PROPS hangar by following the taxiway (do not pay attention to the yellow crosses drawn on it).
If possible, please notify the E-PROPS team of your visit a little in advance.
Have a good flight!

To come by road (coming from Sisteron) :
North of the town of Sisteron, first follow the D1085 road towards Gap.
After the commercial zone (Super U, Brico Dépôt...), take the direction La Motte du Caire - Vaumeilh, east on the D4.
Drive 2.3 km and turn left following the direction Vaumeilh - Thèze, still on the D4, towards the North. Sisteron airfield is indicated.
Continue on this road for 3.2 km, straight ahead, following the direction of Thèze, without turning towards Vaumeilh-village.
The first entrance of the airfield (on your left) goes to the Gliding Club and the restaurant.
The second entrance, 270 m further north, still on the D4, leads to the ELECTRAVIA - HELICES E-PROPS Industrial Zone.
