VZLU was founded to support Czech aviation. The main research and development activities are directed towards innovations that are useful in the aerospace industry. Services and newly developed technologies provided by VZLU can often be exploited outside aviation branch as well.

For the aerospace industry, VZLU provides and maintains a wide range of expert disciplines necessary for aircraft development. The centre disposes of extensive infrastructure including a number of unique workplaces, such as wind tunnels for aerodynamic experiments or large structural test laboratory.

Among the important disciplines in VZLU is considered aerodynamics. Activities in this area comprise of aerodynamic design of aircraft, CFD computations and flow simulation, flight dynamics, and complex testing of aircraft in wind tunnels. An important part of the work consists of the optimization of wings and lift mechanization, including the evaluation of the propulsion unit - airframe interactions with other parts of aircraft. The area of ​​internal aerodynamics is applied in the development of aviation propulsion units and their components. This work includes advanced CFD simulations and technically very demanding developmental work using the VZLU´s experimental research infrastructure. Within the R&D activities are developed new codes and software to address specific aerodynamic tasks.

In the field of aircraft propulsion, VZLU focuses mainly on technical solutions and technologies for the gas turbine engines. Research and development activities are oriented on combustion chambers, design and lifetime of key aviation components such as turbines and compressors, etc. For domestic and foreign manufacturers VZLU carries out a number of demanding experimental activities that are inevitable for engine development. On top of engines related work, VZLU is involved in the development of some aircraft systems, usually in co-operation with Czech manufacturers (OEMs) of the a/c systems.

Another important discipline is strength of aircraft structures. VZLU performs strength analysis, FEM calculations, developmental and certification strength tests of airframes or individual subassemblies of the airplane. The structural tests include mainly static and fatigue life tests. The solved research topics deal with areas of impacts to aerostructures and other structural damage, new methods of NDT inspection and SHM monitoring of aircraft structures, the use of new materials for primary and secondary aircraft structures,  new test methods for certification, etc. Testing laboratories also provide testing of material samples and their detailed analysis, incl. so called “coupon testing”. Part of the strength of structure activities is the multidisciplinary assessment of the dynamic behaviour of aviation structures. These include aeroelasticity analysis and ground vibration tests (GVT).

VZLU deals with the use of composite materials in aircraft structures. R&D activities are mainly focused on the development of infusion-based, cost-effective production technologies that do not require autoclaves, so called "out of the autoclave" technologies. Research includes the use of heat-resistant composite materials and other developed unconventional material systems (e.g. geopolymers). The advantage of VZLU is the possibility of own manufacture of test samples and structure demonstrators and their detailed testing and analysing using experimental infrastructure of VZLU.

VZLU uses its knowledge of aerodynamics, metal and composite structures for development of unmanned aerial vehicles (UAV, UAS, RPAS and other types of drones).
