Airdrop systems are widely used in aerospace fields such as a landing and recovery equipment. The LS-SDYNA was used to simulate the landing process, and to compare the performance of the airdrop system under the rigid and soil ground. Meanwhile, the effect of different lateral wind velocities on the airdrop impact performance was analyzed. The results show that the difference of the maximum overload of the cargo is very small between the case of the rigid and the soil ground when the airdrop system only strikes the ground perpendicularly; the difference is much greater and the deformation effect of soil ground is significant under lateral wind conditions.
