Subsonic Wind Tunnel Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-13362
Indian Lab Suppliers supplies the Subsonic Wind Tunnel (Product ID: 13362) as part of its electronics engineering lab equipment range. It is a suction-type, open-circuit subsonic wind tunnel with a 0.3 m square test section for teaching and basic aerodynamic research.
Quick Answer
Air enters through a 1.5 x 1.5 m bell mouth and dust filters, passes a settling chamber with a 200 mm deep honeycomb and three bronze screens, and is accelerated through a 25:1 contraction into a 0.3 x 0.3 x 1.5 m test section with glass side windows. A six-bladed 0.6 m axial fan driven by a 20 kW, 1500 rpm thyristor-controlled DC motor gives 0-60 m/s, with mean flow uniformity within ±0.25%, total head variation within ±0.5% and longitudinal turbulence within 0.15%. A side-wall three-component strain gauge balance measures axial force (±50 N), normal force (±200 N) and pitching moment (±15 N m) on a NACA 0012 symmetric aerofoil with surface pressure taps. A PC system with touch-screen panels sets the fan speed, drives the motorised probe traverse, scans the pressure taps and plots results.

Where This Is Used
Experiments cover static and total pressure, Pitot velocity measurement, fan speed against air speed, aerofoil surface pressure, lift, drag and pitching moment, and wake surveys. Related: Wind Tunnel System (Product ID: 13364) and Supersonic Wind Tunnel (Product ID: 13366). The tunnel needs a three-phase supply installed by an electrician; keep the fan safety screen fitted and use the emergency stop before any work inside the tunnel.
