Designed for optionally piloted stratospheric missions up to 70.000 ft. altitude.
Elektra Two Solar OPS (Optionally Piloted System) was designed to be used as unmanned electric-solar airplane for stratospheric missions at 70.000 ft. altitude. In direct sunlight it is possible to fly day and night, whereby of course the payload is limited. The aircraft will be delivered in optionally piloted version with the cockpit for one pilot. The autopilot can be activated and deactivated by the pilot. Having pilot inside the aircraft, the autonomous operations without special permissions for UAVs are possible.
The power is provided by combined solar and rechargeable batteries. The electrical energy is summarized at a junction point between the engine and the battery. As long as the energy consumption of the engine is higher as the energy provided by the solar cells the battery has to provide the missing additional energy. If the engine is using less energy as the solar cells provide, the batteries where charged until they are fully charged.
The electrical power unit has double redundancy and is composed of two systems working in parallel. Each of the two systems is composed of one electrical motor, motor controller and battery with battery management system. Two electrical motors are mounted on one shaft, forming a double-redundant engine unit.
The aircraft was developed for fully autonomous navigation. The control can be done either from the cockpit and / or from the ground station.
