Non-Intrusive Stress Measurement System for Small Turboshaft Engines

Hood Technology, along with its partner Williams International, propose to develop, test and supply a Non-Intrusive Stress Measurement System (NSMS) designed specifically for small turboshaft engines. This system will address the issues of these small engines at the sensor, acquisition and software levels, providing a non-proprietary, commercial-based NSMS system tailored for this class of powerplants. The development and live engine testing of a system designed specifically for these engines will produce a common sensing and acquisition platform across a wide variety of applications; create sensors tailored to the temperature, high stress and small installation space required for these engines; develop software and hardware capable of acquiring the low-level and high frequency resonant mode signals peculiar to small turboshaft rotors; and provide a commercial, non-proprietary system capable of delivering NSMS Generation 4 resolution while measuring tip timing and tip clearance both in the laboratory and eventually on operational engines.
