Solar-powered ULM aircraft Elektra One OPS

single-seatelectric motorinstructional

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 and 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 and 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 and solar converter (maximum power point tracker). The solar system is connected to the batteries and 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 and can fly a mission completely autonomously including take-off and landing. The flight mission can be defined by means of a special software before the flight and 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.
