with ELECTRAVIA propulsion system
flight test campaign above Sisteron's airfield (LFNS)
Previously, this aircraft was equipped with a Geiger-Eck-Flytec electric propulsion system.
Now the MC30E Firefly is equipped with a complete electric propulsion system ELECTRAVIA :
- engine and controller E-MOTOR GMPE 102 (maximum power 26 HP)
- custom-made propeller E-PROPS designed for this aircraft
- specific instrumentation on OLED screen, with data recorder
- Lithium-Polymer batterie of 4,7 kWh (KOKAM cells, BMS & PCM Electravia), 33 kg, endurance 55 minutes.
- special optimized engine fairings in order to reduce form drag and interference drag and optimize system's performances.
Empty weight of the aircraft incuding batteries : 113 kg (248,6 lbs)
Between 1rst and 3rd of August, 7 fight tests have been realized. Data are extrated from specific instrumentation developped for this aircraft and this application.
First tests results are very encouraging :
- max climb rate : 6 m/sec / 1.181 ft/mn
- max. horizontal speed : 220 km/h / 119 kt at 3000 ft
- take off run : 62 m / 189 ft
- noise level at take off : 52 dB/A
During passage 150 m vertical airfield, the noise generated by this electric aircraft is lower than the ambient noise in the campaign around.
In comparison with a MC30 Firefly with a 26 CV four-stroke engine :
- max climb rate increases by 41%
- max. horizontal speed increases by 10%
- take off run is reduced of 38%
- noise level at take off is reduced from 61 to 52 dB/A (- 9 dB/A)
In February and September 2012, 4 FAI world records have been established by Jean-Luc Soullier with his MC30E.
Those records are the first in this new FAI subclass RAL1E.
Those records are not the maximum the
pilot could do with this electric aircraft :
He has reached this altitude with only 35 Ah of the 60 Ah he had on the batteries, and the maximum speed was only on a 50 km circuit and not the maximum speed ha could have reached (about 220 km/h).
The pilot has choosen to do such records now and to increase them in the coming months...
