Mathematical modeling of safe payload separation using logos software on chimera-type grids

Abstract

Abstract 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.
