Aircraft engine lubricating oil consumption abnormity monitoring device and monitoring method thereof

Abstract

The invention discloses a monitoring device and a monitoring method for abnormal lubricating oil consumption of an aircraft engine. The monitoring device comprises an engine lubricating oil quantity parameter acquisition module, a lubricating oil quantity abnormity monitoring logic module, a lubricating oil quantity abnormity warning message generation module, a lubricating oil quantity abnormity warning message transmission module and a lubricating oil quantity abnormity monitoring parameter setting and display module. The engine lubricating oil quantity parameter acquisition module acquires lubricating oil quantity parameters of an engine and transmits the lubricating oil quantity parameters to the lubricating oil consumption abnormity monitoring logic module, and after the lubricating oil consumption abnormity monitoring logic module monitors a lubricating oil consumption abnormity event, the lubricating oil consumption abnormity warning message generation module is activated to acquire state parameters related to lubricating oil consumption abnormity and generate a message. And the message is transmitted to a ground system through a lubricating oil consumption abnormity warning message transmission module. The method is used for discovering abnormal events of the lubricating oil quantity of the engine, early warning crew and a ground system in time, and providing analysis data of the abnormal events.

Description

technical field [0001] The invention belongs to the field of civil aviation transportation, and in particular relates to an abnormal monitoring device for lubricating oil consumption of an aircraft engine and a monitoring method thereof. Background technique [0002] Most modern civil aircraft use turbofan engines (referred to as turbofan engines) as their main source of power and electricity. The turbofan engine has the characteristics of high take-off thrust, low exhaust speed and low noise. Road composition. The gases passing through the combustor form a high-temperature, dense, high-pressure gas stream, which then spins the turbine. The rotating turbine outputs torque through the rotor to drive more turbines and fans to rotate, obtaining more gas to generate thrust. [0003] The lubricating oil system is one of the core systems of the turbofan engine. It plays a vital role in the efficient operation of the turbofan engine as follows: [0004] 1) Lubrication: lubricat...

AI Technical Summary

Problems solved by technology

[0015] The outstanding disadvantage of this method is that the discovery of the problem is seriously delayed. Once it occurs, it means that the failure loss is a foregone conclusion with a high probability

[0017] The outstanding disadvantages of this method are: inaccurate monitoring, inconvenient monitoring, and lagging monitoring

For international flights, it may be affected by the company's cost strategy, and the long data transmission may take several days to be transmitted back. Even in an emergency, the airline engineer must go to the foreign site to obtain the data in person

In addition, the abnormal oil consumption that does not trigger the cockpit effect may also be neglected to monitor

[0023] The above methods of abnormal oil consumption monitoring all have the situation of "untimely and inaccurate information transmission, large information granularity, and many risk points of manual operation", which makes it difficult for the preventive maintenance of the engine, and even worse Faults lay hidden dangers
