Lighter than air aircraft or balloon

摘要

The aircraft includes a gas-tight inner casing and a light outer casing (28), whose top section is made of photovoltaic solar cells (26). The outer light casing has carrier elements, to which is secured at least one load and personnel cabin. At least a part (15) of the top section (14) of the light casing of the upthrust body consists of photovoltaic solar cells (13), or is covered with such, with the cells forming together a supply installation (12). The supply unit is in an electric connection to an accumulator (16), or an electric drive unit (10) for positioning a device of the aircraft. If an inner, rigid framework is used, the photovoltaic cells are located on the section of the light casing covering the framework top.
