2 - Summary

Created in 2008, the company Helices E-Props designs, tests and manufactures Hi-Tech Carbon propellers for light aviation: Aircraft, ULM, Paramotors, UAVs and Multicopters, as well as many other carbon parts.
The team of 34 aeronautical engineers and technicians produce more than 45000 propeller blades per year in ultra-modern 2200 m² workshops located at the Sisteron aerodrome, Provence, France (LFNS).
E-Props are the lightest propellers in the world.
In just a few years, E-Props has become the world leader in propellers for paramotors.
Thousands of E-Props propellers, very solid & very quiet, offering exceptional performance, certified ASTM F2506-13, are now in use in 80 countries.
Today, Helices E-Props is the first French equipment manufacturer in non-certified aviation (turnover, production of parts, number of employees, export countries).

3 - Brief History

The ELECTRAVIA - E-PROPS company is also known for its electric motorizations systems developed for leisure aviation : engines, controllers, dedicated instruments, batteries BMS and dedicated propellers, as well as for aircraft equipped with these new successful and silent propulsion systems made between 2008 and 2014.
During 6 years, 70 aircraft with electric engines have been developed by the team, including the famous "ELECTRA" (1rst worldwide 100% electric aircraft, 1rst flight in December 2007), the CRI-CRI Cristaline (1rst worldwide electric twin-engines, world speed record for electric aircraft from 2010 to 2018), the E-FENIX (1rst worldwide electric two-seater paratrike), the E-SPIDER (1rst worldwide electric two-seater paramotor), the ELECTRO-LIGHT (electric motoglider range 1h30)...
At the same time, the E-PROPS propellers, first made of wood and then quickly made of carbon, met with increasing success.
At present, the company has temporarily suspended its works on electric systems, while waiting for batteries allowing a bigger range. The team is now dedicated to the design and manufacture of E-PROPS high-tech carbon propellers and certain other carbon aeronautical parts. Since 2018, E-PROPS offers 4,400 models of ultra-light propellers for paramotors and has become the world leader in this type of propeller. In 2020, a range of more than 100,000 references of hi-tech carbon propellers for Aircraft / Ultralights was released.

Design in digital wind tunnel, optimization with the LmPTR software, elaboration of manufacturing's processes, tests (numerous!) and materials choices, implementation of tools and equipments, brought out of the first models, ground tests then in flight tests : ELECTRAVIA carbon propellers have required 3 years of relentless works, 7 days a week, to succeed in finalizing them. Many tests, some failures, some successes, then still tests, compelling periods followed by discouragement's moments, to obtain at the end an efficient manufacturing"s process and very light and efficient carbon propellers. The propellers of 3rd generation !

- June 2012 : first flights and presentation in a big airshow (Mondial de Paramoteurs de Basse-Ham 2012) of the 1rst electric powered 2-seaters paraglider, the E-SPIDER, with QD2 E-PROPS propeller.
