1. Impacts of the re-categorization of wake turbulence separation minima on flight operation environment of the Vaclav Havel international airport in Praque.

   Actual development of new technologies and measuring methods of wake turbulence as well as wake behaviour measurements require re – categorization of aircraft (see RECAT project/ICAO). The proposed work is to analyze the impacts of the process on safety, aerodrome capacity, and time delays under conditions of the main Czech civil aerodrome flight operation.

2. Analysis methodology of stiffness characteristics of the aircraft hydraulic and electric actuartors

   Currently the hydro and electro-mechanical actuators are starting to use in the construction of power and control systems of aircraft. These actuators must have the required static and dynamic properties in terms of of transmission displacements, forces and powers. Their activities affect the flight characteristics of the aircraft and safety of flight. The goal will be to propose a methodology and analysis of dynamic stiffness characteristics of actuators with theoretical analysis, modeling in Matlab-Simulink and experimental measurements on real actuators.

3. Numerical modeling of the influence of the material interface on failure of composite materials

   Composite materials might my generally perceived as a construction, which consists of two or more different homogenous materials combined together in order to improve their mechanical properties. On these bases, usage of the conventional materials can be further enhanced in the engineering practice. Nevertheless, the problematic part is the internal brakeage of the interface. From the macroscopic point of view the composite material may appear intact, but inside the composite can be developed damage, which may significantly decrease its mechanical load capacity. This damage is generally not visible and is difficult to detect. The most important role in this case plays the interface between the constituents and prediction of the failure becomes rather complicated. Many analytical approaches based on the continuum mechanics have been derived to estimate the effective mechanical properties of the nonhomogeneous materials. However, connection between materials is presumed to be perfectly bonded and effect of the failure of the interface is not captured. In case that interface is weak, mutual interface may fail during the duty cycle. Then, the composite structure is no longer compact although the limit state of the individual materials has not been reached. The opposite case might be that one of the constituents has already been locally damaged, but, due to the strong interfaces, the composite structure is still being compact from the macroscopic point of view. The weaker constituent still particularly can carry the external load even though the overall load capacity of the composite structure might be decreased. Taking into account all previously mentioned effects, analytically estimated material characteristics might be affected by neglecting the interface failure and may not exactly correspond to reality. Finite element method can be advantageously used to solve such a problem. If material characteristics of each constituent are available and the design of the composite is well known, the effective material characteristics can be estimated using the numerical modeling. Furthermore, composite material can be more precisely optimized in order to enhance their applicability and the basis of the internal failure can be investigated in more detail. The main scope of this dissertation thesis is to investigate the effect of the interface of composite materials using the numerical modeling based on the finite element method. To goal is to contribute to the better understanding of the chosen composite materials and their failure. Methodology, which will lead to the more accurate estimation of the mechanical properties, will be carried out. These procedures will be based on numerical modeling of failure of the composite structures. If the process of the failure will be known, recommendations to the composite design in terms of load capacity and reliability can be made.

1. Active control of vortex structures to reduce the drag acting on a car

   The main goal of this PhD thesis is to develop an active control of the rear vortices in order to increase pressure on the rear of a car and therefore lowering the pressure drag generated in this area. In principle, dissipating vortices should decrease pressure in the rear end. Vortex dissipation can be carried out by geometrical changes in order to dampen or eventually by prohibiting the growth of vortices. Further proposal is moving vortices with opposite phase together resulting in lowering of energetic consumption of the vortices. To solve this task is important analyse present state from the start. For this will be used properly selected CFD tool. Because of low level of numerical dissipation seems s to be a good choice for description of flow especially: Partially Averaged Navier-Stokes (PANS) and Detached Eddy Simulation (DES). Optimal CFD tool with the proper turbulent model will be chosen during solving the task. In advance is expected zeta-f turbulent model. For visualization of the vortex structures is necessary properly set up postprocessing tool.
