Abstract

A wireless engine monitoring system (WEMS) including an engine monitoring module mounted directly on an aircraft engine that records, stores, encrypts and transmits full flight engine data. The system is preferably connected to a full authority digital engine controller / engine control unit (FADEC / ECU) and can record several hundred engine parameters at a preferred sampling frequency of about one second. The engine monitoring module is preferably formed as a miniature module mounted directly within the engine cowl of the aircraft engine, with a conformal antenna. The monitoring module can also upload data for onboard processing.

Description

Background technique [0001] The Federal Aviation Administration and other international aviation regulatory agencies require commercial airlines to monitor the health and status of aircraft engines. Any health and status information is used to determine the current performance of the aircraft engine and determine whether maintenance is required. Due to data delays, the existing technology is limited, and the limited amount of collected data limits the analysis. Generally speaking, the state-of-the-art monitoring system is used to measure the total amount indicator. Any resulting maintenance actions are reactive. For example, when an airplane has risen to 1,000 feet after takeoff, some prior art systems only take "snapshots" of basic engine parameters. The data is limited to one time slot during the flight and is not real-time. This data never provides an analysis of the complete state of engine performance during flight. Therefore, the prior art engine analysis system cannot use a...
