construction
The low- wing aircraft with cross tail has a rigid nose wheel landing gear. In the structure of the CFRP rectangular wing with swept back outer surfaces, four cylindrical hydrogen tanks are integrated in the direction of the span , which together with the reserve tanks in the end lobes hold 25 kg. A fuel cell with two stacks of 100 kW rated power is located in the tip of the fuselage, and an accumulator with 8 kWh capacity is behind the cabin. Two Siemens SP70D electric motors in gondolas above the wing drive three-bladed traction propellers.
