The purpose of this paper was to simulate and explore the influence of gust on the airdrop trajectory of airdrop airbag. The impact of gust on the traditional airdrop was studied, and the airdrop accuracy with and without gust was analyzed respectively using the Simulink module of Matlab software. The impact of the vertical gust on the trajectory deviation was a horizontal deviation to the left direction of approximately 600 m. The impact of the horizontal-right gust was a horizontal deviation to the left direction of >3 km, and the impact of the horizontal-left gust was a horizontal deviation to the left direction of >2 km. In conclusion, the horizontal gust had smaller effect on the airdrop trajectory, while the horizontal-right gust had the largest effect on the airdrop trajectory.
