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 swarf content in the transmission system reaches a certain level, an alarm message will be issued. According to the emergency procedure, the helicopter should fly with one engine and land as soon as possible. The maintenance work such as offline detection and lubricating oil spectrum analysis on the ground will seriously affect the use of the helicopter. Security and Training Capabilities

Embodiment Construction

[0018] The present invention will be further described in detail below in conjunction with examples, but the embodiments of the present invention are not limited thereto.

[0019] The on-line disposal system for metal chips in the helicopter transmission system of the present invention mainly realizes the functions of on-board energy storage, energy release and metal chip ablation through the pulse capacitor technology; through the integrated design of the energy storage and ablation device on the machine, it realizes the metal scrap on the helicopter. Chip online ablation automatic control mode.

[0020] Such as figure 1 shown. The transmission system of the helicopter adopts the on-line disposal system of metal shavings. The implementation of the system mainly includes: pulse energy storage device 1, ablation device 2, metal shavings alarm device 7, and electrical circuit test button 8.

[0021] The pulse energy storage device 1 is installed near the transmission system mo...

Abstract

The invention discloses an on-line processing system for metal chips in the lubricating oil of a helicopter transmission system, which includes a detecting device (3), a transmission system (4), a comprehensive display system (5), an onboard power supply (6), a pulse energy storage device (1), an ablation device (2), an electrical circuit testing button (8) and a metal chip alarm device (7), wherein the pulse energy storage device (1) is used for storing energy and releasing energy; the ablation device (2) is used for ablating the metal debris; crew members test the integrity of an electrical circuit through the electrical circuit testing button (8); and the metal chip alarm device (7) performs fault alarm. The on-line processing system of the present invention reduces and avoids ground off-line detection and lubricating oil spectral analysis caused by metal chip alarm faults, reduces the maintenance workload of a helicopter, and avoids the air abort due to the metal chip alarm faults.

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 lubricating oil of a helicopter transmission system. Background technique [0002] The metal shavings in the lubricating oil of the aviation transmission system contain a large amount of information reflecting the working status. The monitoring and online disposal of metal shavings in the lubricating oil have become the main technical means to ensure the healthy operation of the new generation transmission system at home and abroad. Metal shavings monitoring can provide real-time data for the monitoring center of the health diagnosis system of the transmission system, provide deep damage information hidden in the transmission system, 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 transmission system. ...
