Winch Launch Safety Study

A Yahoo groups forum on Glider Winch engineering. Some posts review tension control, ?? ....... http://dir.groups.yahoo.com/group/wi...eer/message/36 http://dir.groups.yahoo.com/group/wi...eer/message/38 and even one thinking about using battery power? http://dir.groups.yahoo.com/group/wi...eer/message/40 Did anyone get a electric battery launch before? There is a German made electric winch called the ESW2B that essentially runs on battery power, albeit an array of 12 volt lead-acid ones. They need to be constantly charged up while in use, either from the mains or a portable generator. I believe that you can't do too many launches per hour without boiling the battery acid. A winch needs at least 300hp or 230kW to launch a modern two-seater glider, so it's a bit too much for normal mains electricity! Derek Copeland
