High-temperature resistant pressure transducer for monitoring of gas turbine combustion stability
The state-of-the-art concerning gas turbine combustors for propulsion and power is marked by the strong R&D effort over the two last decades on low-emission technologies and optimised system performance. The well-known industrial problem that lies behind is the bridle of performance and danger for the combustor integrity due to combustion instabilities that can appear at such operating conditions, achieving critical levels of noise emission, vibration and heat release near the walls. Combustion instability is a multi-parametric problem, which involves a complex coupling between the system acoustic properties, the chamber flow dynamics and the instantaneous and local thermodynamic. This aspect has encouraged the R&D on active control with successful applications on power gas turbine. One critical aspect of combustion monitoring is the sensing: a measurement technique placed onboard shall survey in real-time one significant parameter on combustion stability, here the unsteady and this under aggressive conditions as high pressure ratio, high temperature, presence of a flame, vibration, corrosion, start and stop.

Combustion analysis via the spark plug bore
In close cooperation with Bosch and AVL, Piezocryst Advanced Sensorics has developed a novel spark plug series with integrated pressure measurement function for engine design and quality control. The partners have contributed their respective know-how to this cooperative venture (ignition from Bosch, application from AVL and sensor from Piezocryst). Special priority was given to the achievement of a high-quality pressure signal without the need for an additional bore in the engine. For this, completely new design approaches were pursued in order to solve the problems of extreme miniaturization.

New piezoelectric pressure sensor
Piezocryst of Graz, Austria, was formed in 2003 as a spin-off from AVL and has taken 50 years of experience in sensor development and production to offer the gas turbine marketplace a high-temperature pressure sensor — the type P-2 that can be mounted close to the gas turbine combustion chamber.
Such a position enables the ability to monitor, in a very precise way, pressure pulsations that are induced by firing a very lean fuel/air mixture as required to minimize emissions.
