MATHEMATICAL MODEL AND COMPUTER PROGRAM FOR THE ASCENT AND DESCENT OF HIGH-ALTITUDE TETHERED BALLOONS. SCHEDULE SUB-LINE ITEM 1AD
Abstract
The results of the preliminary study indicate that it is feasible to launch and retrieve high-altitude balloons under certain conditions. It was shown that a 30 million cu ft balloon can be launched in a Summer I-75 percent wind profile at 2000 ft/min, and retrieved in the same wind at -200 ft/min with 20 percent of the helium valved off. Although launch and retrieval are possible in the Winter I wind profile, it is more restricted. The 79 million cu ft balloon in the Winter I 25 percent wind show results similar to the 30 million cu ft balloon in the Summer I 75 percent wind. The results of the feasibility study can be used as preliminary design criteria for components of the tethered balloon-systems-balloon, tether and winch.
