Development of Low-Noise High-Pressure Fans for Ship Collective Protection II: Engineering Development
Abstract
The focus of development of these high-pressure vaneaxial fans for ship collective protection systems (CPS) was on redesigned impellers and stators to increase aerodynamic efficiency and lower the acoustic noise levels produced by the fans. The sound power generated by these fans was been reduced by over 12 dB and the energy consumption by over 20%. The rotors have been designed and fabricated to comply with new factor of safety requirements being proposed for all vaneaxial CPS fans. To validate the suitability of the design for ship applications, a high-impact shock test was conducted with the fan operating at 3,600 rpm. Strain measurements from fan rotor blades were correlated with FEA predictions to validate the design.
