Abstract
Not Available We propose to develop an optical profilometer that can quantitatively measure the shape of compressor blades in an operating turbine engine. The instrument performs the measurement using a single pulse of light and can therefore, freeze the motion of the blade. This instrument can be used to identify the mode shape of operating compressor blades and therefore determine strain due to vibratory excitation. High cycle fatigue due to resonantly excited vibrations is a leading cause of failure in aircraft and power plant turbines. This information can be used to study prototype engine components as well as to monitor the health of operating machinery. During Phase I we will analyze several opto-mechanical designs, select the most appropriate, construct a breadboard, and demonstrate ultra-fast profilometry measurements. Careful attention is placed on developing a robust system that can operate under the harsh thermal and vibratory conditions of an operating turbine. We will work closely with engineers at a leading engine manufacture to develop a prototype design commensurate with the industry's measurements needs and compatible with existing engine access constraints. In Phase II a full scale probe will be constructed and demonstrated on an actual operating engine.
