2023 Elektra Solar Elektra Two Solar

OPS version

Elektra Two Solar OPS can be operated conventionally by a regular pilot or an autopilot for the entire flight from takeoff to landing. 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. The solar system extends the flight endurance & range.

UAS version

The Elektra Two Solar UAS (unmanned) is based on the OPS version. Removing some parts like the instrument panel, flight controls, canopy, seat & safety belts reduces the aircraft weight by 20 kg allowing for increasing the payload or battery capacity. The UAS version is designed to fly up to 20 km altitude.

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.
