BALLOON EQUIPPED WITH A CONCENTRATED SOLAR GENERATOR AND EMPLOYING AN OPTIMISED ARRANGEMENT OF SOLAR CELLS TO POWER SAID BALLOON IN FLIGHT

摘要

A balloon comprises an envelope containing a lifting gas and a concentrated solar radiation solar generator. The solar generator includes a reflector, one or two arrays of photovoltaic solar cells forming a first active face directed towards the reflector and a second active face directed towards the exterior of the envelope of the balloon. The reflector, the first active face and the second active face of the array of photovoltaic cells are configured so as to ensure the first active face and the second active face of the array both generate electrical power provided that the rollwise solar misalignment of the reflector is smaller than or equal to 10 degrees in absolute value.
