The life-saving parachute is a rescue tool designed to save the pilot's life and ensure safe landing in emergency situations on aircraft. During its development, it is essential to evaluate the parachute deployment process and overload conditions. Considering the influence of wind speed and direction on the performance evaluation of airdrop tests for life-saving parachutes, this paper investigates the effects of wind speed and direction during airdrop processes on the straightening velocity and inflation time to fullness of the parachute. Through a combination of simulation and experimental methods, we analyze the impact patterns and propose corresponding correction methods. These efforts aim to provide technical guidance and theoretical support for accurately assessing the performance of life-saving parachutes in airdrop tests.
