Development of the aircraft control devices
Stanislav, Filip ; Zikmund, Pavel (referee) ; Daněk, Vladimír (advisor)
This bachelor thesis handles by literature research the development of airplane control devices since end of the 18th century. The principle of airplane control using three rotational degrees of freedom is known since beginning of 20th century, but there were many attempts to find this principle more than hundred years ago. The three axis control system was used for the first time by Wright brothers and has been used since then. The particular design of the airplane control surfaces is nowadays selected with regard to aerodynamical properties with requirements of minimum weight and adequate strength. An increasing control forces on control stick and pedals in airplane cocpit due to demanding requirements to maneuverability and speed of flight do not allow pilot comfortable and easy driving. Therefore it is necessary to influence this forces. In the text there are described possibilities of influencing them such as problems of feedback from control surfaces to pilot. This thesis gives a comprehensive overview of development of airplane control principles and gives the summary of classical and unconventional airplane control devices.

Position measurement
Marek, Michal ; Klusáček, Stanislav (referee) ; Beneš, Petr (advisor)
This paper describes the possibility of measuring plane controls deflection. It also analyzed a number of principles displacement sensing. Subsequently, it was chosen triangulation distance sensor and this sensor was carried out measurements.

Manufacturing inaccuracies influence on an appearence of the additional moment on a sailboat rudder
Kazda, Adam ; Fic, Miloslav (referee) ; Štigler, Jaroslav (advisor)
This Master’s thesis is dedicated to a generation of an additional torque, which can occur due to the inaccuracy of the manufacturing. This issue is inspired by a real case from 2013. In this work CFD modeling is used to investigate three different sources of the additional torque: misalignment of the rudder, deviation of the propeller shaft and asymmetry of the rudder. A simplified 2D simulation is done for all three cases. This simulation is more suitable for a jet powered boat. Therefore the asymmetry of the rudder is investigated also in a 3D case, where the rotational component of the flow behind the propeller is included.
