Measuring device of the sound field radiates in a turbomachine, in an anechoic chamber.

摘要

The device has a portal frame (10) supporting a set of microphonic sensors transversally distributed with respect to an axis (XX) of a turbomachine, where the portal frame is in the form of a circular arc. The portal frame rotationally and/or translationally moves between an upstream position of the turbomachine and a downstream position of the turbomachine. The frame is provided with temperature measurement sensors and air speed measurement sensors.
