Embodiment 1

[0029] figure 1 It is a flow chart of the steps of a method for monitoring the performance of an integral drive generator provided by an embodiment of the present invention, as shown in figure 1 As shown, the method may include:

[0030] Step 101. Obtain operating data of the overall drive generator, the operating data corresponds to a real-time flight segment and at least two historical flight segments.

[0031] IDG is an important component of aero-generators. It is a high-priced aviation material, and it is expensive to repair after a failure. In the embodiment of the present invention, data analysis can be performed on the operating data such as the temperature, vibration frequency, and power generation frequency of the IDG, to predict the occurrence of failures, and to take preventive maintenance measures in advance, such as lubricating oil service or replacement, so as to prolong the life of the IDG on the aircraft. Longer on-wing use time, avoiding damage expansion of...

Abstract

The invention provides a method and device for monitoring the performance of an integrally driven generator, belonging to the field of aviation. The method can acquire the real-time flight segment of the overall drive generator and the operating data of at least two historical flight segments, and then determine the first trend parameter of the operating data in the first number of flight segments, and the second number of flight segments. The second trend parameter, and then determine the discrete parameter between the first trend parameter and the second trend parameter, and monitor the performance of the overall driving generator according to the operating data, discrete parameters, etc., wherein the first quantity navigation The flight segment and the second number of flight segments respectively include real-time flight segments and different numbers of historical flight segments. The performance of the overall drive generator can be monitored through the discrete parameters, and the short-term change trend and long-term change trend can be compared, so as to predict the fault more accurately. Whether it will happen, to carry out preventive maintenance, improve component reliability, reduce maintenance time, cost, etc., and improve aircraft operating efficiency.

Description

technical field [0001] The invention belongs to the field of aviation technology, and in particular relates to a method and device for monitoring the performance of an integral drive generator. Background technique [0002] IDG (Integrated Drive Generator) is an important component of an aero-engine, and the normal operation of the IDG is a necessary guarantee for the normal operation of the aircraft. [0003] After the aircraft fails, the IDG operation data collected during the flight can be obtained, such as pressure, temperature, vibration amplitude, vibration frequency and other data, through which the cause of the IDG failure can be analyzed to determine the fault Type, cause of failure, etc., to design a maintenance plan to solve IDG failures. [0004] However, the maintenance cost of fault repair after IDG failure is high, and the maintenance after IDG failure also makes the reliability of IDG components low, and the aircraft cannot work normally during the failure a...
