The invention is an Exit Stay Apparatus with Intermediate Flange for Francis and propeller hydraulic turbines. The purpose of the invention is to improve the effec-tiveness of known Exit Stay Apparatus (U.S. Patent #,6,918,744, 07/2005, for Hy-draulic Turbine and Exit Stay Apparatus therefor) in eliminating the axial central vortex and, therefore, in increasing the efficiency and decreasing the flow pressure pulsations in draft tube cone at off optimum operating regimes. The new Exit Stay Apparatus has an intermediate flange between exit stay crown and periphery and two sets of exit stay vanes crown exit stay vanes secured to the exit stay crown and the intermediate flange and peripheral exit stay vanes secured to the intermediate flange and following to the periphery. When installed in the turbine the peripheral exit stay vanes are secured at the periphery. There are more crown exit stay vanes than the peripheral exit stay vanes and then profiles are longer than the profiles of the peripheral exit stay vanes. The Exit Stay Apparatus with Intermediate Flange is expected to have the same peak efficiency as known Exit Stay Apparatus.
