Abstract
Unsteady Pressure Measurements In The NAL 1.2m Trisonic Wind Tunnel Indicated That Levels Of Test Section Flow Unsteadiness Are Relatively Higher As Compared To Similar Tunnels. Such High Pressure Fluctuations Are Not Acceptable And Therefore To Be Attenuated. Acoustic Duct As An Insert To The Settling Chamber Has Been Designed And The Details Of Construction And Anticipated Performance Are Presented.
