One of the most important problems in the development of air weapons is the separation of air weapons from the aircraft. Carrying out this type of tests is expensive, time-consuming and dangerous, so separation and prediction of the trajectory of air weapons using numerical simulation becomes an important part of the study. In this work, a full-scale model of F-18 and a full-scale model of air weapons GBU-31 JDAM were used to test the planned trajectory of separation of air weapons from the wing. The transonic flight mode with Mach number M = 0.962 was considered. The Navier-Stokes and Euler equations were used for numerical modeling, considering the effect of the fluid viscosity effect on the flight path of air weapons during separation from the wing.
