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 an overall driving generator performance monitoring method and device, and belongs to the field of aviation. According to the method, operation data of a real-time leg and at least two historical legs of the overall driving generator can be acquired, and then a first trend parameter of the operation data in a first number of legs and a second trend parameter of the operation data in a second number of legs are determined; then discrete parameters between the first trend parameters and the second trend parameters are determined, the performance of the overall driving generator is monitored according to the operation data, the discrete parameters and the like, and the first number of legs and the second number of legs comprise real-time legs and historical legs of different numbers respectively; the performance of the whole driving generator is monitored through discrete parameters, and the change conditions of a short-term change trend and a long-term change trend can be compared, so that whether a fault is about to occur or not is predicted more accurately, preventive overhaul is carried out, the reliability of components is improved, the maintenance time and cost are reduced, and the operation efficiency of an airplane is improved.

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 operating 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...
