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 (202) comprises an envelope (4) containing a lifting gas (6)and a concentrated solar radiation solar generator (8).The solar generator (8) includes a reflector (10), one or two arrays(204) of photovoltaic solar cells forming a first active face (208) directedtowards the reflector (210) and a second active face (36) directed towardsthe exterior of the envelope (4) of the balloon.The reflector (10), the first active face (208) and the second activeface (210) of the array (204) of photovoltaic cells (206) are configured so asto ensure the first active face (208) and the second active face (210) of thearray (204) both generate electrical power provided that the rollwise solarmisalignment of the reflector (10) is smaller than or equal to 10 degrees inabsolute value.
