Tipperons
WE'RE ALL FAMILIAR with ailerons, their function, effects and shortcomings. Many of us have heard of entire wings rotating slightly in opposite directions to achieve the same effect without some of the shortcomings of ailerons. Either of these systems provides response improvement with a significant efficiency loss. Tipperons give further improvement in response with far less efficiency loss. Tipperons are a refinement of the rotating-wing principle, a refinement in both efficiency and simplicity. Instead of the entire wing rotating, only a short section of the wing tip rotates. On a glider of 100-in. wingspan, a 12-in. section of each tip will do just fine. Polyhedral is not recommended. Less than normal dihedral is recommended. Use shoulder-mounted wings.
