The application belongs to the field of aero-engines, and in particular relates to a countermeasure method for abnormal rotation of aero-engines. Including: Step 1: Obtain the test run steady-state data; Step 2: Obtain the abnormal rotation identification time; Step 3: Obtain the characteristic value of the abnormal rotation identification; Step 4: Establish the abnormal rotation fault criterion; According to the data, the disposal countermeasures after the abnormal reversal occurs. The method for dealing with the abnormal rotation of the aero-engine of the present application can quickly identify and take disposal measures when the abnormal rotation is found, so that the engine can avoid running at low speed and high temperature, ensuring the safety of the engine; it can greatly reduce the wear and tear of machine parts and the degree of secondary damage such as blade damage, while retaining evidence for troubleshooting to the greatest extent, providing an effective means for reducing losses.
Description
technical field [0001] The application belongs to the field of aero-engines, and in particular relates to a countermeasure method for abnormal rotation of aero-engines. Background technique [0002] When the engine is working normally, its control system will limit the engine speed or temperature to the specified state according to the position of the throttle lever; At this time, the control system still controls the engine state simply according to the throttle position, and it is necessary to increase the fuel supply to the combustion chamber, which will cause the engine temperature to rise or even exceed the allowable temperature of the thermal parts, mechanical wear or blade damage, etc., seriously endangering the work of the whole machine Safety. Therefore, it is necessary to establish rapid identification and fault handling countermeasures for abnormal reversals. At present, when an abnormal rotation occurs, only after the exhaust gas temperature exceeds the limit v...
