Cheeseman Award Paper: Bluecopter Demonstrator: The State-of-the-Art in Low Noise Design
Authors / Details: Sascha Schneider, Rainer Heger, Peter Konstanzer, Airbus HelicoptersAbstract
The present paper intents to present the state-of-the-art in current rotorcraft noise reduction technologies using the example of the innovative BLUECOPTER demonstrator (Figure 1). All described noise reduction features, notably the active rudder and the Fenestron® noise measures such as the advanced rotor blades, the evolved stator design and the innovative Fenestron® lining concept, contribute to the challenging and ambitious objective of reducing the noise emission of the rotorcraft directly at the source in a wide range of operationally relevant flight states. The paper incorporates results from the latest BLUECOPTER acoustic flight test campaign in final configuration and demonstrates the exceptional low noise signature of the BLUECOPTER demonstrator in various flight conditions.
