Online disposal system for metal chips in lubricating oil of helicopter engine

Abstract

The invention discloses an online disposal system for metal chips in lubricating oil of a helicopter engine. The online disposal system comprises a pulse energy storage device (1), an ablation device (2), a detection device (3), the engine (4), a comprehensive display system (5), an ablation disposal switch (6) and a metal chip alarm device (7). The pulse energy storage device (1) is used for storing and releasing energy. The ablation device (2) is used for ablating the metal chips. A flight crew manually controls the number of times of ablation of the metal chips through the ablation disposal switch (6). The metal chip alarm device (7) is used for fault alarming. According to the online disposal system, ground offline detection and lubricating oil spectral analysis caused by alarming faults of the metal chips are reduced and avoided, the maintenance workload of a helicopter is reduced, and aborting caused by the alarming faults of the metal chips is avoided.

Description

technical field [0001] The invention belongs to the field of helicopter flight health diagnosis, and in particular relates to an online disposal system for metal shavings in helicopter engine lubricating oil. Background technique [0002] The metal filings in the lubricating oil of aero-engines contain a large amount of information reflecting the working status. The monitoring and online disposal of metal filings in the lubricating oil have become the main technical means to ensure the healthy operation of the new generation of engines at home and abroad. Metal shavings monitoring can provide real-time data for the monitoring center of the engine health diagnosis system, provide information on deep damage hidden in the engine, and at the same time perform trend analysis, early warning and online disposal of the wear state to ensure the healthy and efficient operation of the engine. [0003] The online disposal technology of engine metal shavings is still blank in domestic av...

Problems solved by technology

Magnetic detection technology generally needs to be combined with lubricating oil spectral analysis technology for off-line detection of metal shavings. The off-line detection method has a long cycle, high cost, cumbersome measurement methods, and human factors.

[0004] During the flight of the helicopter, when the metal shavings content of the engine reaches a certain level, an alarm message is issued. According to the emergency procedure, the helicopter should fly with one engine and land as soon as possible. The maintenance work such as off-line detection and lubricating oil spectrum analysis on the ground has seriously affected the safety of the helicopter. sex and combat ability
