The Aerospace Research and Test Establishment (referred to by its Czech initials, VZLÚ) is a national centre for research, development and testing in the field of aeronautics and space. The main mission of VZLÚ is to generate new knowledge and transfer it into industrial practice, as well as to provide its partners with maximum support in the development of new products. As a multi-discipline research organisation, VZLÚ exploits synergic effects and also contributes to the progress of the automotive, rail, defence, security and power industries and civil engineering. VZLÚ supports a wide range of disciplines necessary for the development of products related to the aviation industry. Activities in this area comprise aerodynamic design, CFD calculations, flow simulations, flight dynamics and complex testing of aircraft in wind tunnels. VZLÚ is also one of the pioneers for space research in the Czech Republic and develops scientific instruments for space experiments and surveying. Main engineering services provided for space sector include stress analysis, thermodynamic simulations, thermal analysis, reliability analysis, design and development of electronic systems. VZLÚ uses its expertise in the field of aerodynamics for the development of unmanned aerial vehicles (UAVs) and propellers, and provides a wide variety of research, development and testing for aircraft turbine engine producers.
