2 - Summary
Created in 2008, the company Helices E-Props designs, tests and manufactures Hi-Tech Carbon and Carbon-Titanium propellers for light aviation:
Aircraft, Ultralights, Paramotors, UAVs.
The team of 51 aeronautical engineers and technicians produce more than 50000 propeller blades per year in ultra-modern 7200 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.
40 ultralight and airplane manufacturers have chosen E-Props to equip their aircraft.
Thousands of E-Props propellers, very solid & very quiet, offering exceptional performance, certified ASTM F2506-13 and EASA CS-22J, are now in use in 84 countries.
Today, Helices E-Props is the first French equipment manufacturer in non-certified aviation
(turnover, number of parts produced, workshop area, number of employees, export countries).
The company is targeting EASA POA Part 21G certification in 2023 to produce certified propellers. First propeller certified by EASA : DURANDAL-3 (March 2023)
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.
The team is now exclusively dedicated to the design and manufacture of its E-PROPS high-tech carbon propellers.
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.
In 2022, E-Props has started the process with EASA, DGAC and OSAC to certify the production (Production Organisations Approval Part 21G)
and some propeller models according to the EASA CS-22 standard.

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 !
