Numerical study of a set of screen-exhaust devices taking into account the influence of the helicopter main rotor

Abstract

The results of a numerical study of the flow of exhaust gases in screen-exhaust devices tested on a helicopter with TV3-117 engines are presented. As a result of the study, an analysis of pressure losses and flow structure was performed. According to the results of calculations and modeling, the direction of further calculation and experimental studies aimed at improving the flow part of the screen-exhaust device was determined
