We have a project that deals with ballistic glider designs. We've tested with designs that were of paper cones, weighted front and back using paper clips. However, our best achieved height-to-distance ratio was 1:1... we need it to at least 1:2. We were wondering what other ballistic designs would enable a 1:2 height-distance ratio? The parameters: no wings/fins/propellers no motors/prefabricated parts, etc. totally ballistic flight characteristics The flight vessel is released by hand at a height of 5.5m and must 'glide' to a target 12m away. Thank you for all suggestions!!
