E-PROPS PROPELLERS for DRONES :
The development of new aircraft such as drones and different types of big multicopters requires ultra-light and highly resistant propellers with very good
efficiency. To meet this need, E-PROPS has developed a range of fixed and adjustable pitch carbon propellers
, ideal for prototypes and series.
The E-PROPS are available for gear drive combustion engines and for electric engines.
The ELECTRAVIA - E-PROPS team is known for its electric motorizations systems developed for leisure aviation (engines, controllers, dedicated instruments, batteries BMS, special propellers),
as well as for aircraft equipped with these new successful and silent propulsion systems made between 2008 and 2014.
During 6 years, more than 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)...
The ELECTRAVIA engineers have developed controllers and batteries BMS, have integrated engines and adapted airframes of different aircraft. As they didn't find specific propellers for electric
engines on the market, they also have designed, tested and manufactured propellers specially adapted to this type of engines.
From 2014, the company has temporarily suspended its electric motorisation activities, pending the availability of batteries with greater autonomy and a recharging time more
suited to aeronautical use.
The E-PROPS team is now solely dedicated to the design and manufacture of its propellers.
Today, this great expertise combined with the means implemented to produce carbon propellers allows E-PROPS to participate in many innovative aircraft projects,
as a supplier of ultra-light and extremely efficient mechanical propulsion solutions.
E-PROPS, a major global player in the aircraft carbon propeller sector, is involved in many innovative drones and multicopters projects.
Confidentiality does not allow to mention most of these projects here for the moment.
