Description In this research a pyramid shaped parachute inspired by the design of Da Vinci is analyzed using computational fluid dynamics. The effects of Reynolds number on the pyramidal parachute is analyzed with and without vent holes. The Reynolds number is varied from 1×104 to 1.5×105, and the drag coefficient varies, beyond which the drag coefficient remains constant. Vent holes are provided at the apex of the canopy, the ratio of vent area to the base area is increased from 0% to 10%. moment coefficient values for canopy with varying vent ratio is obtained for different angle of attack to find the static stability of the parachute. It is seen that the canopy with vent ratio of 6% is more stable than the canopy without vent. The oscillation of the parachute is obtained by fluid structure interaction between the fluid and structural mesh. The oscillation of parachute with 0% vent hole ratio and 6% ratio is obtained.
