A method for analyzing the ejection performance of a projectile ejection mechanism considering an additional load of the present invention comprises: dividing a launching tube (10) accommodating a projectile (1) into a first chamber (20) and a second chamber (30), physically defining conditions generated in the first and second chambers (20, 30) when ejecting the projectile (1) in consideration of an additional load, and mathematically modeling a projectile ejection mechanism by a physically defined equation to determine the design parameters of the projectile ejection mechanism based on the additional load; and applying the design parameters to the input conditions of a performance analysis program built in a gas generator missile launcher simulator (GGMLsim) program to allow a GGMLsim to analyze the performance of the projectile ejection mechanism with an empirical equation, instead of a flow analysis code, for which a large amount of computational complexity is required. In particular, analysis time can be reduced, and design parameters can be easily analyzed while obtaining the analysis result of the performance of a projectile ejection mechanism considering an additional load.
