| description | The present invention relates to a method for detecting performance of the lubricant cooler in aircraft auxiliary power unit APU, comprising: acquiring APU-related messages within a time period; obtaining the operation parameters of the (APU) lubricant cooler, the operation parameters comprise: lubricant temperature (OT) and load compressor inlet temperature (LCIT); the revised lubricant temperature (OT) is obtained by the following formula: the revised lubricant temperature = lubricant temperature (OTA) - the load compressor inlet temperature (LCIT); determining the performance of the APU lubricant cooler is in stable phase, decline phase or malfunction phase according to the change trend of the revised lubricant temperature (OT) with respect to time. |
