The company E-Props, world leader in carbon propellers for paramotors and well placed for microlight and LSA propellers, currently has 45 employees. Based at Sisteron airfield, 87% of its propellers are exported to 84 countries.
At the end of 2021, E-Props began two certification procedures. First, the application to the DGAC & OSAC for a Production Organization Approval (POA) according to the EASA Part 21 G regulation. The certified parts will be manufactured in the new 4,000 square meter factory that is currently being built, including several CNC machining centers, robots and additive manufacturing machines. In this positive energy building, everything is designed and implemented to design and produce propellers in an eco-responsible approach.
At the same time, E-Props has applied for Type Certificates from the EASA for some E-Props models suitable for use on certified aircraft. The first range to be certified will be the Durandal range: 3-blade carbon-titanium ground adjustable propellers (weight 2 kg), designed for gear-drive engines. The summer has been dedicated to testing: 50 hours of flight, vibration tests, traction, bending and torsion tests. Then it will be the turn of the Glorieuse range, Constant Speed carbon-titanium 3-blade (4 kg) for Rotax 4-stroke.
Work is in progress with the certifying agencies. The company plans to apply for a Design Organization Approval (DOA), which will give it greater independence in the certification of its future propellers. E-Props is currently working on a number of models, particularly for direct drive engines and turbo-prop engines.
