Low-noise propeller design for future regional aviation
Low-noise designs are needed if turboprops are to be the future of regional flight. This makes initiatives such as those within the Europe’s Clean Sky 2 IRON project coordinated by CIRA crucial without compromising on performance. The project has a focus on the design and testing of propellers, setting the ambitious target of a 6 dB near-field noise reduction at cruise compared to a baseline design. Preliminary results indicate that the high-level objectives of the project are on track and that the innovative propellers have significant noise reduction.
