Control systems of Kaplan Turbine
 Pavelka, František ; Kárník, Jan (referee) ; Fic, Miloslav (advisor)
The main objective of this bachelor´s thesis is to list briefly the most common types of water turbines and explain the construction and especially regulation of Kaplan water turbine. Second task is to describe individually both regulatory mechanisms and movements in the machine during the regulation by distributor and by blades of runner wheel. The next intention is to describe the influence of regulation on the efficiency curve and further briefly explain and compare the modern control systems of turbine regulation with the old way using the centrifugal regulator.

Fuel Supply Regulation of Turboshaft Engine
 Ondráček, Vladimír ; Hubáček, Tomáš (referee) ; Dundálek, Radim (advisor)
Elaborated project gives a complex design of backup hydro-mechanical unit for fuel supply of turboshaft engine TS 100. Required function of backup unit is to secure basic function of engine TS 100 over failure of primary electro-mechanical fuel system. Backup hydro-mechanical unit consists of hydrostatic fuel pump, centrifugal regulator, valve of maximum and minimum pressure, switch valve and signalization of activation hydro-mechanical unit. Parameters of hydro-mechanical unit are designed considering requested rotations speed of output shaft of engine and its allowed fluctuation. Calculation of basic parameters and dynamical calculation of behavior of the system regulator with engine is made in program DYNAST Shell. Additional calculations were made in program Microsoft Excel. Own design of hydro-mechanical unit is made in 3D design software Pro/Engineer.
