| Abstract: | In order to make the object with a round parachute fall safely in the shortest time, a method of multiple opening and closing parachutes in the air is proposed, each opening or closing of the parachute is controlled by the control system, and the mechanical structure suitable for multiple opening and closing of the round parachute in the air is designed. The algorithm in the control system can calculate the point at which an object needs to open or close a circular parachute, based on the height of the object when it is about to fall, the maximum falling speed that the circular parachute can bear and the safe falling speed of the circular parachute, the control system allows the round parachute to be timed to open or close. The simulation results show that the proposed method can make the object with circular parachute fall safely in the shortest time. |
