Abstract
Turbomachine du type comportant une pluralité d'aubages placés sur le trajet d'une veine d'air ou de gaz délimitée par une paroi symétrique selon l'axe, ladite paroi 10 présentant des orifices 13 communiquant avec une cavité 11 extérieure à la veine d'air, de structure générale symétrique, ladite cavité étant reliée à au moins une canalisation 4, caractérisée par le fait que des moyens de rupture de symétrie sont prévus à l'intérieur de ladite cavité, par exemple sous la forme d'une portion de tube 15 montée dans la canalisation 4 de façon à faire en partie saillie à l'intérieur de la cavité 11.
