Original abstract
The contribution is aimed on the study of a tail, which is occurred in the draft tube of a turbine, when turbine is running out of its best efficiency point. The equation of the tail in Lagrange's coordinates are introduced. The shape of a tail is studying, on the basis of mathematical model, in dependence of specific energy. The conditions of stability of the tail are derived with dependence of boundary conditions.

Přednáška je zaměřena na studium copu, který vzniká v savce turbiny při práci stroje mimo optimum. Jsou sestaveny pohybové rovnice copu v Lagrangeových souřadnicích. Na základě matematického modelu se studuje tvar copu v závislosti na měrné energii. V závěru jsou odvozeny podmínky stability copu v závislosti na okrajových podmínkách.
