Abstract
In a method and apparatus for measuring pressure, sound and vibration, particularly for the flow analysis on missiles or airplanes, a sensor device which is used to sense pressure or sound waves, is linked to a structure of a structural part in order to measure forces acting upon the structural part surface. The sensor device is arranged completely inside the structure of the structural part or on the rear side of the structural part surface. In particular, the sensor device may comprise a piezoelectric foil which is situated under the structural part surface.
