Electric aircraft

BL1E Electra
French BL1E Electra F-PMDJ: the first registered electric aircraft in the world. First Flight in Dec, 2007

Electravia, organized as an association called APAME, first flew its "Electra" electric-powered open-cockpit airplane on Sunday, 23 December 2007 at Aspres sur Buech airfield, Hautes Alpes, France. Test pilot Christian Vandamme flew the strut-equipped aircraft for 48 minutes, covering 50 km (31 mi). The BL1E "Electra" is powered by an 18-kW (24 hp) disk-brushed electric engine driven by a 47 kg (104 lb) KOKAM Lithium-Polymer battery power pack.[7][8][9] The BL1E "Electra is the first registered aircraft in the world powered by an electric motor with batteries.[10]

MC15E Cri-Cri

On 5 September 2010, pilot Hugues Duval established a world speed record for electric aircraft with his twin engine MC15E CriCri “E-Cristaline”. The aircraft was equipped with Electravia engines, controllers, batteries and propellers. During the Pontoise Air show, a top speed of 262 km/h (141 kt) was recorded by Aero Club de France organizers. Then, on 25 June 2011, during the official flight presentation at 2011 Paris Air Show (Salon du Bourget), Duval established a new world record of 283 km/h (175.46 mph)[11]

Since 2008, Electravia designs and manufactures full carbon propellers for aviation, including fixed pitch, ground-adjustable pitch and variable pitch models. A complete range of propellers for paramotors, ultralights, aircraft and UAV is made in the 1,700 m² workshop on Sisteron's airfield (LFNS). E-Props propellers claim to be the lightest on the market.[13][14] Usage is restricted to visual flight rule conditions, bad weather flying is not allowed by the manufacturer.[15]
