Numerical Predictions of Flow Over Drag Parachute

Nor Azwadi Che Sidik, Aman Ali Khan

Abstract

This paper presents numerical predictions of drag parachutes using commercial software. Two models of drag chutes with different projected area were selected to examine their flow dynamics parameters such as drag coefficient, drag force and flow characteristics downstream the drag chutes. Turbulent ranges of flow speed were considered. It was seen that the improved version of drag chute gave more stability in flow dynamics compared to the conventional type of drag chute.
