Aircraft Hydraulic Systems
Puller, Tomáš ; Vaněk, František (referee) ; Třetina, Karel (advisor)
Work "Hydraulic system of aircraft" is focused on the issue of hydraulic transmission of forces to control the airplane. The first and second part summarizes the main characteristics of hydraulic systems and the basic physical properties of liquids.The third section describes various components of hydraulic systems and their characteristics. The fourth part contains a description and diagrams of different types of hydraulic circuits and the fifth part describes types of servocontrol systém of aircraft. In chapters 6 and 7 are descriptions of hydraulic systems of two Czech airplanes, L - 159 and L – 410. The next part contains statistical summary of power installations in small and medium-sized airplanes, and comparison of properties of different forms of transmission power. Finally, the evaluation of the statistical summary is carried out.
Mechanical construction of hydraulics arm
Vodrážka, Jakub ; Březina, Lukáš (referee) ; Věchet, Stanislav (advisor)
This bachelor’s thesis deals with design of a hydraulics arm. The main purpose of this hydraulics arm is the possibility to use it in education project which is a part of hydraulics systems lessons. This arm consists from few parts which are connected together by rotary joints. This arm is actuated by linear hydromotors, furthermore there is a magnetic position sensor. Autodesk Inventor 2008 was used during the arm design process. There are three main parts in this work. First part deals with fluids systems, the second part shows the position sensor properties and the last part presents some cases of arm design with deformation verify. A lot of supplement is presented at the end of this work as pictures of the model of the arm or pictures of some parts of the model.
