Derating on the low voltage devices with a thermal trip unit
Dobrovolný, Jakub ; Vetiška, Vojtěch (referee) ; Dostál, Lukáš (advisor)
Electrical devices are secured as not to injure living creatures via electric current and damage or destroy machinery due to the effects of electric current. Circuit breaker is a device responsible for protection of an electrical circuit against damage. The main aim of thesis is the correct function of the thermal trip unit when it exposes to the thermal warming. The thermal trip unit is depended on heating of a bimetal before overcurrent flow. The goal of thesis is temperature and voltage drop profile from measured values. Verification of the measurement is done in SolidWorks Flow Simulation software. According to simulations are determined currents for correct function of the thermal trip unit in different temperatures of an environment. The most important result of the thesis is correct setting of the operating current in the circuit breaker.

The tail unit desing
Holiš, Michal ; Zablatzký, Jiří (referee) ; Vaněk, František (advisor)
In this bachelor’s thesis is created an overview of possible patterns, designs and mechanisms conductive to stability and reduce the physical demands placed on pilot. Introduction is dedicated to accession of terms, that is necessary for further understanding or just occur in text. In thesis are further discussed patterns, where are mentioned its advantages and disadvantages. Next chapters describe types of balance and derating of the rudder. Last two chapters describe internal construction of empennage and its fixation to fuselage.
