Aerodynamic testing has been a primary
method of assessment and verification of the aerodynamic
models for many years. This is essential
for modern aerospace, automotive and construction
engineering as all kinds of objects such as aircraft
and space vehicles or buildings and bridges
can be tested in this way. A wind tunnel examination
enables determining the aerodynamic forces
acting on a given structure. Such knowledge is
particularly useful for calculating the strength of
structures especially during high-speed winds.
The values of aerodynamic forces are also used to
reduce the intensity of flow energy around objects,
moving elements in particular by developing their
geometry as close as possible to the ideal shape [1,
2]. Aerodynamic tests are carried out all over the
world, particularly in research centres [3]. Also,
Lublin University of Technology examines aerodynamic
flow around a wind turbine and airfoils.
The results presented in this paper were developed
during the realization of the project funded by the
Polish National Science Centre. The paper discusses
the partial results of the related wind tunnel
study done for airfoils with additional active airflow.
The project’s main assumptions, test preparation,
bench design and test results are given in
the further section in the paper.
