Reliable and stable operation of jet engines is crucial for safety. A jet engine undergoes several measuring campaigns throughout its lifecycle to prove that it meets all the requirements.
Our single-crystal PiezoStar ultra-high temperature pressure and acceleration sensors are specifically designed for jet engine testing, which is performed during the research and development phase. It includes vibration and pressure pulsation measurements in hot environments up to 700°C (1.300°F) and provides the engineering team with important information about the operating condition of the jet engine as well as with a basis for further developments.
This particular type of testing is performed after manufacture and also after any major overhaul work. Later in the jet engine's lifetime, for example, the same high-temperature sensors are used in an end-of-line performance test to verify proper functioning of the engine.
