The use of pressure weapons in Brazil for sporting purposes has been growing every day. However, the lack of information about these equipment both on the part of the manufacturers and in the literature itself leaves a gap in athletes who wants to know more about their armaments. In that regard, raising different parameters of these armaments becomes important for the growth and development of sports that involve pressure armaments. In the proposed work, it will focus specifically on Airsoft armaments, a sport that at first became known for simulating military combat but which nowadays has several modalities. At the end of the work, it is expected that the simulated results found will be close to the physical quantity that are possible to be evaluated, whether this evaluation is carried out experimentally or through a comparison with other systems.
