Objective of the study was to analyze ski jumpers’ actions in the flight phase; to examine the possibilities of constructing a simulator (wind tunnel) and determine the peculiarities of its use in simulation exercises.
Methods and structure of the study. The main research method applied in the study was the analysis of scientific and methodological literature, which was carried out with allowance for the structural features of modern ski jumping complexes and coaching experience.
Results of the study and conclusions. Simulation exercises are the main means of formation of technical skills in athletes. They closely approximate the competitive exercise structure.
Modern simulators create the conditions of the acceleration and take-off phases. Yet, there are no ready-made solutions for practicing the flight phase, which is only possible in conditions of real trampoline. At the same time, it was found that foreign athletes try practicing the flight phase in a horizontal wind tunnel. However, the airstream in such tunnels is different from the naturally moving airstream on the trampoline in the flight phase.
One of the possible solutions to this problem could be the design and construction of a special simulator - a wind tunnel that would simulate the real trampoline conditions, creating moving airstreams with changing angles. Similar designs are used in parachute trainings when practicing Wingsuit flights.

Keywords: ski jumping, simulation exercises, flight phase, airstream, wind tunnel, simulator.
