Materials for space technology
Bačová, Alena ; Tříska, Václav (referee) ; Petrásek, Miloslav (advisor)
This master´s thesis is dealing with an analysis of materials used for space technology. The thesis is divided into eight main parts. The first part defines space technology. The second part introduces the issue of designing satellites and planning the space mission. The third part describes the effects of the environment on space technology before launch, during launch and flight, in space, and during atmospheric entry. The fourth part introduces the most used standards in Europe for the space industry. The fifth part analyses materials and their application in the space industry. The sixth part provides an overview of aerospace materials tests. The seventh part analyse processes and damage of material during and after the impact of a small object. The last part is devoted to the preliminary design of the device for a more accurate analysis of the behaviour of the material during the impact of a small object.

Design of the six seat helicopter with one turboshaft engine
Nasibullin, Bulat ; Tříska, Václav (referee) ; Petrásek, Miloslav (advisor)
The aim of this work is to develop a preliminary design of a six-seat helicopter with a turboshaft engine. The preliminary design of the helicopter consists of processing statistical data on similar helicopters, which are then, based on the specified requirements, used to estimate the basic weight parameters of the helicopter, the main geometric parameters and to determine the type and power of the propulsion unit. It consists of calculations of basic geometric parameters of the aircraft and engine selection. Part of another solution is the aerodynamic calculation of the supporting rotor, from which both the performance of the helicopter in suspension and in forward flight flow. In a special part of the project, the attention is paid to the system of balancing the reaction torque, in this case fenestrone and the solution is supplemented by some specific means installed on the tail beam, which help to balance the reaction torque and improve the directional control parameters of the helicopter.
