Abstract

One important aid for sailplane pilots planning their flights is the speed polar. Despite very detailed methods of calculation, up to now one can only determine rather exactly such curves by experiments. But the classical ways for this task require special flight tests with a lot of time; so one can only measure few gliders. In addition, the results have inaccuracies, which vary with time as well. Therefore a new method ascertaining the speed polar is desirable which can be simply applied and can be permanently used aboard many sailplanes. The following three sections of this paper contain basic ideas for this aim.
