Since the parachute descent is more complex, the cost dropped and other tests designed to be very large,simulation studies with a very large parachute design significance.Parachute canopy breathable fabric has great influence on the parachute descent, The purpose of this study is to consider the case of breathable fabric, parachute simulation study to explore and study the impact of the round parachute fabric breathability steady decline stage, breathable fabric will parachute into account is a major feature of the simulation. The simulation results show the feasibility of this article parachute simulation research methods, and by the results of comparative analysis, found breathable fabric canopy has an important effect on the parachute drop after full phase. As appropriate to improve fabric permeability, can reduce the drag coefficient, reducing the pressure difference between the upper and lower surface of the canopy, reduce flow separation vortex phenomenon, increasing the stability of the parachute.

The simulation of canopy fabric air permeability’s influence on the round parachute during the landing process
