deHavilland Low Speed Wind Tunnel
University of Glasgow
The University of Glasgow de Havilland wind tunnel has a test section of 2.74 m x 2.1 m x 5 m. It has a platform 6-axes load cell beneath working section, and various capacity load cells. Data Acquisition: 192 channel simultaneous data acquisition (16 bit) at up to 500kHz. 64 channel simultaneous data acquisition (24 bit) at up to 128kHz. Outputs: Forces & moments, pressure, velocity (Stereo PIV for high resolution over large area – up to 1m x 1m).
