Introduction of the Research Group

Department established 75 years ago as Department of Aircraft, works as leader in country and internationally recognised partner on teaching and researching the aeronautical sciences including the design, investigating the aerodynamics, study the flight performance, flight dynamics and control, operation (flight operation, maintenance and repair), the working group strongly cooperates with on the working groups of department and takes part in many different national and international (EU supported9 projects. The working group successfully develops the new, disruptive technologies, identification, evaluation and applicability of new technologies, estimation of technology life, electric and hybrid- electric aircraft, studying the flight performance of the hybrid air vehicles, innovation operation concepts, safety and security analysis, impact estimation. Strong competences of the working group are the model formation, development of the mathematical models, simulation, especially implementation of the numerical methods, based on systems theory and system engineering approaches and using the life cycle impact assessment in design, and flight testing.
