Purdue researchers develop sensors to detect and prevent turbine engine failure

Researchers at Purdue University have developed a monitoring system that could prevent disastrous failures in gas turbine engines.

The technology uses pressure sensors to detect rotor forced response vibration, one of the most common causes of premature blade failures in gas turbine engines. This vibration can be so intense that it affects the engine’s ability to function correctly.

“The flow field inside a gas turbine engine is very complicated and noisy,” says Purdue researcher Yujun Leng. “The key challenge is how to filter our all the noise and just listen to the sound produced by the blade vibration.”

According to researcher Nicole Key, pressure sensors are already included in most gas turbine engines for other purposes, so the Purdue technology can be implemented to measure and monitor blade vibration efficiently and at a low cost.

“With the help of big data analytics, the blade vibration information can be used to predict the possible engine failure and optimize preventive maintenance schedules,” says Key. “This technique has great potential to be used as a real-time blade vibration health monitoring system for the gas turbine engines used in both aviation and power generation.”

The researchers have filed a provisional patent for the technology through the Purdue Research Foundation Office of Technology Commercialization, and they are now looking for partners to further develop and commercialize the technology.
