This paper tracks the variation of dynamic pressure, velocities, Reynolds number of the airflow in different areas of the outer shell following the flow direction. This study is based on the simulation obtained using Fluent 6.3 program for different air flows dislocated by the propeller based system (0,5–1,0 m3/s) for 0° and 45° flaps angles. In the air flow direction four random areas where chosen and the mentioned parameters values where determined, thus obtaining the way these parameters vary. This analysis allows an interpretation of the influence some physics and mechanical parameters have on the flow.
