Design Manufacturing of Low Noise Compact Axial Fan

Source summary

Develop a compact low-noise axial fan for airborne communication equipment. The source constrains size to 60 by 60 by 38 mm, mass to 175 g, operating airflow to 60 CFM at 300 Pa and noise to 65 dB(A), while allowing some relaxation of peak airflow. It specifies aircraft-compatible supply options and temperature ranges; speed control is desirable. Operating airflow must not be sacrificed merely to meet noise targets.
