Subsonic Wind Tunnel

Code: PN# RA-WT-30

The RA-WT-30 SUBSONIC WIND TUNNEL is a tool used in aerodynamic research to study the effects of air moving past solid objects. A wind tunnel consists of a closed tubular passage with the object under test mounted in the middle. A powerful fan system moves air past the object. The test object is instrumented with a sensitive balance to measure the forces generated by airflow. 

Features 

  • Static pressure in a reduced cross-section
  • Determining the volume flow with a Venturi tube
  • Determining the wind speed with a pressure head sensor
  • Measuring the air resistance (drag) as a function of the wind speed
  • Drag coefficient: Relationship between air resistance and body shape
  • Plotting pressure curve on an airfoil profile
  • Recording the airfoil profile polars in a wind tunnel
  • Measuring students' own airfoils and panels in the wind tunnel
  • Verifying the Bernoulli equation
  • User Manual
  • Lab Manual (detailing equipment setup and experimental procedures for each experiment)
