WORKSHOPS

 

 

ELECTRAVIA's headquarters, research office and workshops are located on Sisteron'airfield LFNS (town : Vaumeilh), north of Sisteron, Alpes de Haute Provence - exactly between Grenoble et Marseille.

 

 

ateliers E-PROPS workshop

 

The premises are perfectly functional: workshops and offices on one side, big storage zone for planes near the door looking onto the runway. The roof is equipped photovoltaic panels.

 

 

Ultra-modern main workshop (1200 m²) :

- Different and dedicated workshops: propellers workshops, mechanics, electronics for a production capacity of 18500 blades / year

- 12 machining centres, including one 8-axis centre with laser scanner to analyze blades and hubs.

- 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.

- A system of electronic sensors (accelerometers and strain gauge), which is settled on the propeller's hub. A wireless connection Bluetooth allows to get back the data on a computer in the plane.

- A steam room medium temparature / small capacity

- A steam room high temperature / big capacity

- A lathe and a milling machine

- A TIG welding system

- A cabin of painting of 15 m²

- An assembly hall

- A storage zone for operational planes (400 m²)

- Offices and training room

 

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

 

 

 

In September 2014, a new 500 m² hangar has been built on the same aera, for tests and for special propellers production.

 

In August 2015, the company has bought an ultralight with a Rotax 912S; this airplane will be equipped with innovative instruments (DAU : Data Acquisition System) to record all propellers parameters in all flight configurations, to propose ever better propellers.

 

In July 2017, E-PROPS has implemented two new production equipment :

- a machining centre custom designed and built 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 brooch on 5-axis 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 ts 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 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 propellers for leisure aviation !
