[0002] Skydiving is a complex sport in itself, and military skydiving is more demanding because it involves a large number of military personnel skydiving continuously. After the skydiver leaves the plane, if the main parachute is not opened, the skydiver will continue to rotate in multiple dimensions under the action of the airflow. In this process, how to resist dizziness and how to calmly complete the action of opening the auxiliary parachute are training projects that must be carried out on the ground.
