- 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

- Composite structures under dynamic loading
Currently, behavior description of metal structure under dynamic loads is standard, with evaluation of the cyclic load or impact problems and structure warping during crash. The aim of the work should be FEM modeling system of structure behavior describing the real behavior under dynamic impact and design of damping elements ensuring the protection of the crew of the aircraft on impact. As part of the work is expected wide research of the present state, mastering the available standard FEM solvers, design methods, proposal of modeling and evaluation methods, and demonstration on real part of the structure.

The goal of doctoral studies is technology development of non-contact vibration measurements of an aircraft structures with regard to solving aero elastic phenomena in flight. Student will perform a search in the area of frequency analysis and existing resources to solve mechanical vibration and aeroelastic phenomena and will propose their own procedures.
The solution will actively utilize the available measuring equipment of Institute of Aerospace Engineering. PhD student can handle the technique of non-contact measurement and provide a new method of frequency analysis with applications to the aircraft structure.
- Optimization for unconvection energy resources and power Unit
DP is targeting to optimize the basic aerodynamic, geometric and mass characteristics of the aircraft with unconventional energy resourcesfor the LSA to GA CS 23 category
- 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.
- Technologies for safe UAS operations under bad weather conditions
Rapid development of drones (unmanned aerial systems) and their commercial use lead to the need for research of related problems, to ensure safe operation of drones. One of key problems are operations in all weather conditions, limits for UAS operations, and enabling technologies.
Proposed work will include analysis of weather conditions and its influence on operations of UAS. In addition, detailed research of technologies enabling operations in bad weather conditions, which are suitable for application on UAS, is expected. This will include also detailed hazard analysis and safety assessment for proposed solutions. The research will lead to formulation of one “priority problem”, with the target to develop technologies dealing with identified problem (i.e. sets of sensors, …). Developed technologies will be supported by experimental evaluation.
- Topologi optimalization of structure produced by Additive Layer Manufacturing
As part of the development of advanced technologies, nowadays the significantly driven methods as Additive Layer Manufacturing starts to be used, which enable the production of complex shapes that cannot be produced by standard machining or molding techniques. The legitimacy of these new technologies requires a true optimization design process.
As part of the work is expected mastering commercially available FEA systems and their coupling to the optimization procedures, or define a custom optimization process, taking into account the benefits and limitations of ALM technologies.
