Abstract

Developments made at the Institute of Jet Propulsion and Turbomachinery of the Technical University of Aachen on the topic of miniaturized multihole pressure probes to be utilized in transonic turbine flows are presented. The main emphasis is on the numerical description of the flow around the probe head. A very efficient tool, the panel method, was used to calculate the pressure distribution on the surface. By the aid of this method the design process of a pneumatic multihole pressure probe can be supported. The influence of some geometry variations on the flow around the probe head is investigated, and the probe coefficients are presented and discussed
