Issued topics of Doctoral Study Program
- Adaptive flow control based on local pressure distribution over wing
Main objective of Ph.D. study is closed loop active flow control concept feasibility study. The particular concept should be based on direct pressure field monitoring in the vicinity of the wing surface and consequent manipulation instead of conventional flow control based on state variable changes (e.g. accelerations, angular velocities etc.). The study would be focused on following main areas: - analysis and selection of most appropriate actuator system - analysis and selection of most appropriate sensors for pressure distribution monitoring - control law definition (based on measured parameters) - design of demonstrator for wind tunnel testing Main tools used thorough the study should include theoretical research of current state of the art, numerical modelling of concept, laboratory tests of concept demonstrator and if possible demonstration on small UAV.
- Analysis and modeling of stiffness characteristics of hydraulic and electric actuators in the aircraft control system.
The current trend in the construction of small transport aircraft, equipped with automatic control systems, is to use of hydraulic and electrical control units for the control surfaces of the airplane. These aggregates are the high demands on weight, energetic and dynamic properties. When analyzing systems control of the airplane it is necessary to consider the effects of aero-elastic phenomena in the construction of aircraft and flight modes. The negative effects of these aeroelastic phenomena can extend to accidents airplane. Inclusion of hydraulic or electric actuators to the airplane system control creates significant additional risk of such aeroelastic phenomena developing. The aim of this thesis is to make the effect of stiffness properties of hydraulic and electric actuators for aircraft aeroelastic phenomena. Based on theoretical analysis and modeling of the properties actuators control devise a methodology for assessing their effects on the generation of hazardous aerodynamic phenomena. It is also necessary to focus attention on methodology of experimental determination of the stiffness characteristics
- Damage tolerance properties of integrally stiffened structures and possibilities of their improvement.
The role of integrally stiffened components in aircraft structures is increasing due to reduction of assembly operations and manufacturing costs. Examples of such components are integrally stiffened skin panels of aircraft fuselage and wings made by high speed machining. The integrally stiffened panels have not so good resistance to crack growth comparing built-up riveted panels. A possible way how to improve damage tolerant performance of integrally stiffened panels is the application of composites and adhesive bonding technology for local stiffening of structural components. From technological point of view the method is based on application of hybrid adhesive bonded joints of metals and composites. The aim of the research: The aim of the research is to achieve data about influence of design, technological and operational factors on the strength and life of hybrid composite/metal joints and to verify influence of local stiffening with the application of composite materials and adhesive bonding technology on fatigue crack growth.

- Impelementation of bionic principles in adaptive flow control
Analysis of bionic principles of flight, boundary layer control, lift control and other by birds, insects and fishes for its use in adaptive flow control in aerospace and automotive applications. Design of particular system inspired by those principles, its numerical optimization and experimental validation in wind tunnel and possibly in flight.
- Safety/Reliability Assessment Methods and their application on "More-Electric Aircraft" Concept
Modern trend in the development of systems for aircraft is towards so called “More-Electric Aircraft” (MEA) concept. Replacement of mechanical, hydraulic or pneumatic systems by electrically controlled systems is key characteristic of this concept. Major goal of the work is to analyze current trends on this field and to select suitable systems for adaptation to MEA concept. Activities related to the work include: assessment of forces and power necessary to replace functions of selected aircraft systems by electric components, development of safety/reliability assessment methods and related certification issues.
