Karpovich, E. A., Zanegin, S. Yu. Low-Speed Open-Type Wind Tunnel with a Large
Diffuser Divergence Angle for Propeller Testing // Vestnik of the Moscow Aviation
Institute. 2025. Vol. 32, No. 4. P. 31-41.
This article outlines the design of a compact open-circuit wind tunnel, featuring a centrifugal blower and a wide-angle diffuser, specifically intended for propeller testing. The wind tunnel is capable of
accommodating propellers up to 20 inches (0.508 m) in diameter and achieving a maximum test-section velocity of 20 m/s (72 km/h). It operates using aa15 kW motor that drives the blower at 960 RPM.
