Abstract
Lighter-than-air (LTA) systems and methods. The LTA may include a super-pressure balloon (SPB). A plurality of tendons may extend around and bias the SPB to a pumpkin shape. The SPB may use a compressor to provide a variable amount of ballast air by pumping in or expelling out ambient air. A zero-pressure balloon (ZPB) may be attached with the SPB. The ZPB may provide lift for the system. The SPB may include lifting gas and ballast air to provide both lifting and descent functions. The LTA may include a payload.
