Abstract
1. Способ охлаждения газотурбинных двигателей при аварийном (внезапном) выключении энергетических установок, заключающийся в том, что измеряется частота вращения ротора (роторов) двигателя, температура масла на выходе из газотурбинного двигателя или на выходе любой из его опор, и формируется управляющее воздействие на исполнительный орган-стартер системы запуска газотурбинного двигателя, момент включения которого определяется в зависимости от типа, применяемого на двигателе стартера (воздушный, гидравлический, электрический), во время выбега ротора (роторов) газотурбинного двигателя при его аварийном (внезапном) выключении система автоматического управления энергетической установкой выдает команду на включение стартера, который приводит во вращение ротор (ротора) двигателя с частотой вращения n, в течение времени τ или до достижения температуры масла на выходе из газотурбинного двигателя или на выходе любой из его опор величины, исключающей коксование масла, при этом топливо в камеру сгорания двигателя не подается. ! 2. Способ охлаждения газотурбинных двигателей при аварийном (внезапном) выключении энергетических установок по п.1, отличающийся тем, что в случае применения на газотурбинном двигателе электронногидравлической или электрической системы запуска возможно регулирование частоты вращения ротора газотурбинного двигателя n в зависимости от изменения температуры масла на выходе из газотурбинного двигателя или на выходе любой из его опор. ! 3. Способ охлаждения газотурбинных двигателей при аварийном (внезапном) выключении энергетических установок по п.1, отличающийся тем, что в случае применени�1. The method of cooling gas turbine engines during emergency (sudden) shutdown of power plants, which consists in measuring the rotational speed of the rotor (s) of the engine, the oil temperature at the outlet of the gas turbine engine or at the output of any of its bearings, and a control action is formed on the executive the starter body of the starting system of a gas turbine engine, the moment of switching on of which is determined depending on the type used on the starter engine (air, hydraulic, electric), during the run-out of the rotor (s) of the gas turbine engine during its emergency (sudden) shutdown, the automatic control system of the power plant issues a command to turn on the starter, which drives the rotor (rotor) of the engine with a speed of n for a time τ or until the oil temperature at the outlet from a gas turbine engine or at the outlet of any of its supports of a value excluding coking of oil, while fuel is not supplied to the combustion chamber of the engine. ! 2. The method of cooling gas turbine engines during an emergency (sudden) shutdown of power plants according to claim 1, characterized in that in the case of using an electronic hydraulic or electric starting system on a gas turbine engine, it is possible to control the rotational speed of the rotor of the gas turbine engine n depending on the change in the oil temperature at the outlet from a gas turbine engine or at the outlet of any of its supports. ! 3. The method of cooling gas turbine engines during emergency (sudden) shutdown of power plants according to claim 1, characterized in that in case of application
