A New Method of Aircraft Engine Calibration

Abstract

The invention discloses a new method for aircraft engine calibration, which calculates the working range of historically calibrated engine parameters, fits the central curve of the working range, and uses the engine parameter ground detection equipment to directly write the curve as the standard model value curve of the same type of aircraft. into the engine parameter converter. The invention directly writes the standard model value curve into the engine parameter converter through the engine parameter ground detection equipment, replaces the traditional engine parameter calibration method, saves labor costs, improves work efficiency, and has better practicability.

Description

technical field

[0001] The invention belongs to the technical field of aircraft engine parameter calibration, and in particular relates to a new method for aircraft engine calibration. Background technique

[0002] Engine parameter calibration is an essential and important process in the commissioning phase of the warehouse after the current aircraft assembly is completed. Since there is a large error between the measured value and the standard value when the engine parameters are not calibrated, the engine parameters must be calibrated after the engine is installed for the first time or replaced. In this way, in the process of use and maintenance, it can be more realistic and accurate to monitor whether the state of the engine is normal, or if some parameters are found to be close to the edge of failure, the engine can be inspected and maintained in advance in time to kill the failure in the bud. Ensure the reliable performance and stable life of the engine, and ensure the...
