Embodiment Construction

[0020] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing preferred embodiments of the invention. However, the invention may be embodied in many different forms and should not be construed as limited to only the described embodiments. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Like reference numbers refer to like elements throughout, and prime notation is used to indicate similar elements within alternative embodiments.

[0021] The present invention is a wireless engine monitoring system (WEMS) that may use the basic components of the ground data link unit disclosed in the '165, '179 and '734 patents incorporated by reference. The system of the present invention reduces the functionality and size of the WEMS module, is mounted directly on the jet engine, and is preferably interfaced wi...

Abstract

A wireless engine monitoring system (WEMS) includes an engine monitoring module that is mounted directly on an aircraft engine and records, stores, encrypts and transmits full flight engine data. The system preferably interfaces to the Full Authority Digital Engine Controller / Engine Control Unit (FADEC / ECU) and can record hundreds of engine parameters with a preferred sampling frequency of about one second. The engine monitoring module is preferably formed as a miniaturized module directly mounted on the aircraft engine within its cowling and has 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 condition of aircraft engines. Any health and status information is used to determine the current performance of the aircraft engine and determine if maintenance is required. Existing techniques are limited due to data latency, and the limited amount of data collected limits analysis. In general, the aggregate indicators are measured using state of the art monitoring systems. Any resulting maintenance actions are reactive. For example, some prior art systems only take a "snapshot" of basic engine parameters when the aircraft has climbed to 1000 feet after takeoff. This 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, advanced predictive and diagnostic techniques are not avail...
