Mathematical modeling of a system of vortices formed at the entrance to a subsonic air intake

Abstract

The paper analyzes the reasons for the premature  decommissioning of engines due to the ingress of foreign objects (FO). One of the main ways of getting FO – a surface vortex-is highlighted. The results of mathematical modeling of the degree of influence of a number of factors on the  characteristics of vortices formed at the entrance to an isolated air intake are presented. The article presents a comparative analysis of the results of mathematical and experimental  modeling.
