Research on Optimization Design of Parachute Suspension Points for a Certain Pod Airdrop

During the airdrop test of a certain pod, the parachute system located at the tail provides deceleration function. The suspension point of the parachute system is an important part for transmitting loads during the descent process of the pod, and the transmission path of the suspension point load is related to the attitude stability of the Pod-Parachute-Combination (PPC) after parachute deployment. This article evaluates the attitude stability of the pod after parachute deployment by combining the flight path angle and the attitude angle of the PPC. Finally, the simulation results are verified by combining experimental images. The research results indicate that when using double suspension points, the attitude stability of the PPC is good, which can provide a reference basis for the suspension point design of subsequent pod airdrop tests.
