摘要
The blade (10) has a set of aerodynamic surfaces such as a pressure face (18) and extrados (20), and an electroacoustic source (14). The electroacoustic source is provided with two emissive surfaces (30, 32) that form an integral part of the aerodynamic surfaces of the blade. The electroacoustic source is arranged such that the emissive surfaces vibrate in phase during operation. The electroacoustic source is provided with a transducer i.e. piezoelectric actuator (22), that is mounted in a cavity (12) of a body (11) or metal structure of the blade.
