3rd Quarter 2013Electrical switching & drive systems & components
At the Parisian Le Bourget air show, Siemens, EADS and Diamond Aircraft showcased the next generation DA36 E-Star with a serial-hybrid electric drive. This drive concept enables quiet electric takeoff and a reduction in fuel consumption and emissions of up to 25%. The second generation aircraft has proved that this technology is suitable for commercial use. The aircraft exhibited at the Le Bourget air show successfully completed a one-hour maiden flight in June. Thanks to the innovative integrated drivetrain from Siemens, it was possible to reduce the empty weight of the motor glider by 100 kg compared with its predecessor in 2011. This means the aircraft has a realistic capacity and range as expected from a commercial aircraft.
The propeller of the motor glider is electrically driven by a hybrid system consisting of an integrated drive system from Siemens and a generator that is powered by a small Austro Engine Wankel rotary engine. The DA36 E-Star 2’s drive system provides an output of 80 kW during takeoff and a continuous output of 65 kW. The electric motor weighs just 13 kg. At 5 kW/kg, its specific continuous output is twice that of the first prototype and about five times greater than that of a typical industrial electric motor. The power electronics and gearbox are integrated into the electric motor. For takeoff and climbing, additional energy is drawn from a battery which is recharged during cruising.
“The technology is scalable and will soon be making its way into small aircraft and in the future, commercial aircraft with 50 to 100 passengers,” said Ralf-Michael Franke, CEO of Siemens Drive Technologies division.
