Определение допустимого значения теплосъема топливомасляного теплообменника в зависимости от режима работы разрабатываемого ГТД

Abstract

The oil system is one of the main internal cooling systems of the gas turbine engine. It provides heat removal from the lubricated friction units of the engine. Heat exchangers are used to remove heat from the oil on the engines. The main parameter characterizing the efficiency of a heat exchanger is the amount of heat removal, depending on the design of the heat exchanger, the working area of the heat exchange surface, the properties of the liquids used, their pumping and temperatures. During the development of the oil system of the aviation gas turbine engine, a problem arose in overheating of the fuel and insufficient cooling of the oil. This was due to incorrect heat dissipation parameters. As a result of the correctly provided parameters, the radiator confirmed the required characteristics and received permission for the use of the engine under development.
