Aircraft for use as e.g. polar station, has flap rotatable around perpendicular axis or four flaps positioned at different sides of aircraft, where pump transfers light gas from upper side to lower side of partition wall

摘要

The aircraft has a volume (10) separated into upper and lower parts by a partition wall (11). An opening flap is provided at an end and below a pump (15). The flap is rotatable around a perpendicular axis or four flaps are positioned at different sides of the aircraft. A pump transfers light gas from upper side to lower side of the partition wall during damage of the upper part and with losses of the light gas. An independent claim is also included for a solar wind power plant formed with solar cells and wind power plants.
