Cosmic debris, or cosmic debris, is a term used in astronautics to describe all anthropogenic inactive cosmic bodies, fragments and remnants of objects created by the decay of space technology, which has been launched into orbit by man. The cosmic splinters are characterized by the uncontrolled movement of fragments with high velocities, and thus high kinetic energy. With the development of cosmonautics and its gradual integration into everyday life, the increasing amount of space debris poses a serious problem threatening the future of space missions. Thus, humanity is currently facing a potential threat, in the form of the prevention of spaceflight and the use of space technology for many generations. The aim of the work would be to design a device (interception satellites) for active reduction of already formed cosmic fragmentation, for example after an orbital collision or explosion of other objects. Another possible goal is the use of this device, in the form of an active shield, protecting sensitive elements of space technology. The satellite would take up a position to protect another space object in the event of an imminent collision. Thus, all the kinetic energy generated by the impact would be absorbed by the capture satellite and the main important body would not be destroyed (eg Hubble Telescope, ISS, etc.)
Vehicles moving at high speeds cause turbulent flows in the environment around their bodies. The individual components of the vehicle (rear-view mirrors, antennas, aerodynamic elements, etc.) can further influence this flow locally with a significant impact on the formation of aerodynamic sound. The aim of the dissertation is to research the problem of the interaction of moving bodies in a gaseous environment with an impact on the formation of aerodynamic sound sources and the subsequent propagation of sound in the surrounding acoustic environment. The result of the work is a methodology suitable for the analysis of the influence of individual body components on the generation of aerodynamic noise of the moving vehicle. Research activities include the developement of a physical description of aerodynamic processes, the design of discretization approaches and the development of algorithms for evaluating the solution of a given physical problem. The use of available software resources (e.g. OpenFOAM, ANSYS CFX, ANSYS FLUENT, ADAMS, ACTRAN, etc.) and the creation of new algorithms in programming languages (e.g. Python, Matlab, Fortran or C) is assumed. The results will be verified by technical experiments. The work will be solved in cooperation with ŠKODA AUTO a.s. During the study, close cooperation with an industrial partner and real application of work results are expected. The study includes participation in international conferences in the field, publications in journals and possibly an internship at a world-renowned research facility abroad. Those interested in studying should present basic theoretical knowledge of aerodynamics and the ability to work with CFD programs.

Fuel systems of small turbine engines use various methods of fuel supply to the combustion chamber, so there are different fuel nozzle designs, such as pressure swirl nozzles (simplex / duplex), evaporator tubes, spraying rings or airblast nozzles. Fuel nozzles are a very important part of the whole system, their proper function is a must to ensure sufficient engine efficiency and the fuel nozzle requirements are very high.

Experimental investigation is based on the use of pin-on-plate simulator. The attention will be paid to titanium and cobalt alloys with consideration of DLC coating.
The topic of the thesis is the development of a digital car twin for the development and testing of autonomous vehicles and ADAS systems.
The impellers of modern turbomachines, such as turbochargers, are constructed in an integrated disc and blade design, resulting in low internal damping values and high resonant stresses. The topic of the dissertation is therefore focused on the research of unconventional approaches to reduce the amplitudes of forced oscillations of rotors. The topic is supported by the Josef Bozek National Center of Competence for Surface Vehicles.
