White Star’s not working with off the shelf balloons though– they’ve got a bigger goal: DIY tropospheric superpressure balloons. these will be capable of multi-week flights, if successfully built. Dan Bowen’s talk– Jump to 3:30 into this talk, and see the superpressure tetroon discussion. 5:40, discussion of Rochte’s designs.
My balloon guide’s rigging is for short flights in confined urban areas. We’re going to use a different rigging for aerial photography.
One corner of the balloon is used for filling, and is tied off, like a trash bag. A second corner is re-enforced, and a loop of tape attached. To the tape is tied a short length of line. The knot used is aBowline.
Helium can lift approximately 65lb. per 1000 cubic ft. from the images in the video, the balloon was no more than 12ft in diameter, or approximately 900 cubic feet. The boy, the balloon, and all the equipment can’t weigh less than 65lbs. Next time you want to wast millions of public money, do the math first.
