High-Resolution Non-Intrusive-Stress-Measurement-System (NSMS) Sensor

The goal of this project is to develop a magnetic sensor that will accurately detect the time-of-arrival of turbine engine blades from outside the engine case and from standoff distances from the first stage fan via the inlet aperture, with the intent of achieving performance comparable to the Generation 4 NSMS optical probes. Phase 1 will focus on the key elements of the sensor in order to prove the feasibility of the technique. Phase 1 will concentrate on two primary issues: 1) the standoff distance, and 2) the accuracy and resolution in blade time-of-arrival that could be achieved by the NSMS electronics.BENEFITS: A reliable NSMS sensor with standoff capability and high resolution would be of significant benefit to both the military and the civilian turbine engine market, as well as to the stationary power generation market.
