	abstract = {The parachute inflation process is a typical time-varying, non-linear and fluid-structure coupling problem, especially inairdrop condition. For its complexity, numerical model of the inflation process is a big challenge, and most of the modelsestablished before still have room for improvement. There were two common problems that the first one was ignoranceof inertia force of canopy and line, and the second was that took stretch speed as the initial airdrop speed in modelling.Thus, a modified finite element model for canopy inflation process based on ALE (Arbitrary Lagrange Euler) method wasestablished   that   the   inertia   force   of   canopy   and   line   was   taken   into   consideration   and   the   initial   airdrop   speed   wasestimated   and   adjusted.   The   opening   load   in   finite   mass   situation   during   deployment-inflation   process   of   C-9   typeparachute was calculated. The result was compared to experimental data and calculated data of unmodified models. Itwas indicated that the opening load and peak time of modified model was the closest to experiment and the snatch loadwas   also   calculated   and   confirmed,   so   that   the   correctness   and   rationality   of   the   model   was   verified.   Then   the   factorinfluence   of   inertia   force   and   initial   airdrop   speed   was   analysed,   which   provided   a   reference   for   parachute   numericalmodelling.},
