Abstract

Based on arbitrary Lagrange-Euler method, a vortex ring parachute simulation model was set up, and its inflation was studied under the condition of infinite mass and low-speed airflow. Through changing line length, canopy area and airflow velocity, the inflation processes were simulated, and the time-histories curves of projective diameter and spinning rate were obtained. The influence of structure parameters and airflow velocity on parachute motion characteristics was analyzed. The results show that the limit spinning rate of vortex ring parachute increases with the difference increase of trailing-edge pitch line and leading-edge pitch line. With smaller canopy area and larger airflow velocity, the opening time and steady time of the parachute are shorter, and the limit spinning rate is higher, which is good for inflation and improving kinematic stability.
