Reel-up and -down system for balloon-borne instruments
Abstract
Balloon-borne winches were developed in order to observe stratospheric vertical microstructures. Kevler rope (1 mm diam) suspending payload instruments is wound on a spool through a ropeguide. Accurate reel-down depth can be measured by counting the spool rotation and the ropeguide turn. In the first flight of September 1982, four cycles of 600 m reeling of a 6 kg payload were performed. After that, the battery consumption was much improved by utilizing a deccelerator and a hysteresis brake. The improved type of winch has succeeded in reeling up and down a 12 kg payload through 1 km for three cycles at 24 km level in September 1983.
