Analysis and Consideration of the Geometry of a Control Unit Operating Elements in Modeling of Dynamic Processes in Hydroautomatic Systems

In this paper, the modeling of dynamic processes occurring in hydromechanical control systems of aircraft engines with allowance for the geometry of the operating elements of the control devices is considered. A mathematical description for various configurations of the operating slots of the control throttle valves and accounting for these design features in a mathematical model of an isodromic regulator are provided. The effect of throttle element slot configuration in an aircraft hydraulic system is discussed. The effect of the geometry of the spool valve hydraulic booster on the dynamics of the power plant with a detailed description of the study results is demonstrated.
