Investigation of influence of geometrical parameters of slide valve of guide vanes on engine operation instability ТV3-117

Abstract

As part of the study of the engine ТВ3-117 stable operation issue, the influence of the spool hydraulic dis-tributor geometric dimensions on the dynamics of the guide vanes regulator is investigated. Scheme and princi-ple of operation of guide vanes hydromechanical regulator are described. A mathematical model is presented, which allows to obtain static characteristics and to analyze dy-namic characteristics of the guide vane regulator, to check the probability of changing the regulator dynamics when changing the parameters of the hydraulic distributor spool.
