Temperature Simulation of Aviation Engine Oil Supply System
This article introduces the thermodynamic characteristics of the aviation engine oil supply system,establishes a temperature simulation model of the engine oil supply system based on Amesim software,calculates the flow rate,pressure,and temperature distribution at key nodes of the system at different engine speeds using the simulation model,and analyzes the influence of oil temperature on oil supply pressure,as well as the influ-ence of oil flow rate and engine speed on the outlet oil temperature of the bearing cavity.The calculation results show that the oil supply pressure decreases with the increase of oil temperature;The outlet oil temperature of the bearing chamber decreases with the increase of oil flow rate and increases with the increase of engine speed.This article provides important means and methods for the design,optimization,and performance analysis of aviation engine oil systems.
