2023 Elektra Solar Elektra One Solar

Extremely low noise level

Less than 50 dB noise level (German LTF-UL 2020) – moderate rainfall noise. Operation in noise protected areas possible.

Operational costs

45 EUR/h (OPS version), aircraft depreciation cost, electricity & battery, maintenance, insurance.

Redundancy

Dual redundant propulsion system. Each of two subsystems is composed of motor, motor controller, battery. Dual redundant power supply for avionics & autopilot. In case of failure of motor, motor controller, battery or all of them in one subsystem, the aircraft is able to climb with at least 1.5 m/s.

In case of OPS, double redundant electronic flight instruments.

In case of UAS, triple redundant autopilot system composed of flight control computer (FCC), navigation sensors, air data system. Double redundant actuators.

Solar system

The solar system serves as a range extender. It is composed of solar generator & solar converter (maximum power point tracker). The solar system is connected to the batteries & propulsion unit so that the solar energy can be used for the motor directly, for charging batteries or for both in parallel.

Optionally piloted system (OPS)

Elektra One Solar OPS is equipped with autopilot system. The pilot can switch to the autopilot mode & can fly a mission completely autonomously including take-off & landing. The flight mission can be defined by means of a special software before the flight & changed or adapted during the flight from the cockpit or from the ground control station. Elektra One Solar OPS can be delivered for operation without pilot in the cockpit.

Unmanned aerial system (UAS)

Elektra One Solar UAS is equipped with a triple redundant autopilot system. By removing the instrument panel, flight controls, canopy, seat & seat belts, the empty weight of the aircraft is reduced by 20 kg, allowing an increase in payload or battery capacity.
