RESEARCH ON THE INFLUENCE OF STRUCTURAL PARAMETERS OF FUME EXTRACTOR ON ITS PERFORMANCE ON THE TANK USING ANSYS FLUENT SOFTWARE

Abstract

This paper focuses on studying the influence of certain structural parameters of fume extractor on its performance of the 125mm smoothboregun 2A46-M on the tank T90S. Using numerical methods, interior ballistics calculations for the gun are conducted to determine input parameters for the simulation. A simulation model of the gas extraction process for the fumeextractor was developed using the module Fluent of the Ansys Workbenchsoftware. Based on this model, the study examines the effects of variables such as the number of intake-exhaust holes, the inclination angle of these holes, the installation position of the fume extractor, the size of the intakeexhaust holes, and the shape of the exhaust holes on their operationalefficiency during firing. The results of the investigation provide essential reference parameters for calculating and designing fume extractors for the tank-mounted cannon of the tank T90S.
