A current collector has a sliding contact for making electrical contact with a conductor profile of a conductor line and an antenna for insertion into a longitudinal slot, running in a longitudinal direction of the conductor line. The sliding contact and the antenna can be moved jointly towards the conductor profile in a feed direction by a feed device of the current collector. A conductor line has a conductor profile running in a longitudinal direction, having an elongate cavity and a longitudinal slot adjoining the cavity and running in the longitudinal direction. The conductor profile has at least one sliding contact groove for the sliding contact of the current collector. The antenna is mounted on the current collector so as to be moveable with respect to the sliding contact in the feed direction, and the conductor profile has at least one spacer slide surface running in the longitudinal direction, for a spacer slide of the current collector.

Disclosed are aircraft configured to perform tethered and untethered flights as well as methods of operating such aircraft. During a tethered flight, the aircraft is connected to a power line using its connecting module. While tethered, the aircraft can receive electrical energy from the power line and use this energy for propulsion and/or storage. The aircraft comprises a propulsion module for providing vertical and horizontal thrusts. In some examples, the aircraft comprises a transport module. The transport module may be removably attached to the propulsion module and be replaceable with another transportation module. During an untethered flight, the electrical energy is supplied to the propulsion module from a battery and/or a generator on board of the aircraft. The untethered flight capability can be used for landing and takeoff, flying away from power lines or when the power line is not operational, and other like examples.
