Engine Health Diagnostics Using Radar
Abstract
This paper reviews the work undertaken by the Advanced Technology Center to demonstrate that low power microwave radar can be utilized for condition monitoring of a jet engine. The impact of a damaging item of FOD on a highly stressed compressor blade or HCF may often not produce visible damage, but the impact will have altered the stress within the blade. This can drastically alter the life of the blade and possibly instigate early fatigue failure, often with catastrophic effect. This paper postulates that the EHDUR system could be used to monitor both the engine intakes for FOD ingestions and the compressor stages for changes in there vibration characteristics. The system can be easily fitted to engine test rigs by utilizing existing inspection ports. To date the sensors have in excess of 300 hours of rig time.
