Radio Frequency Sensors to Locate and Measure Compressor Blade Vibration
Abstract
In this proposed effort, we intend to investigate a non-contact, Radio Frequency(RF) multiple-input multiple output (MIMO) array-based method for monitoring compressor vibrations, including during flight, that has potential to offer a significant advancement in engine health monitoring. A goal of the effort is to develop methods for sensing, characterizing and localizing vibrations from blade and stator airfoils. The effort will involve the build-up of a rig with means to induce vibrations at various locations within the compressor; the build-up of a sensor array at microwave and mmwave frequencies, and the development of detection, characterization and classification algorithms. RF measurements will also be conducted in higher-TRL rig environments.
