Параметрическая оптимизация имитационной модели гидравлической установки для самолетов пятого поколения

Abstract

The article explores the use of mathematical modeling tools to determine the parameters of effective ground-based mobile hydraulic systems for fifth-generation airplanes capable of creating the necessary pressure in the hydraulic actuators of glider controls. Based on the analysis of factors that ensure the magnitude of the hydraulic fluid pressure, an imitation model of ground mobile hydraulic systems has been developed and a mathematical model has been formed on its basis reflecting the relationship of the required pressure with the capabilities of the ground mobile hydraulic system. The mathematical model is written in the form of a nonlinear conditional optimization problem, the solution of which allows us to find the optimal installation parameters: the rotational speed of the drive motor and the displacement of an axial-piston pump.
