Ae 460 Lab

The first and foremost procedure for this lab is to be familiarized with the lab equipment. The principle components to be interacted in this lab is the work station, the wind tunnel, the AOA adjusting handle, the airfoil with tufts, and the wind tunnel frequency controller. Switch the control mode for the tunnel frequency controller to be LOC or local of local control would be used instead of remote control. Make sure that the tubes are connected in a way such that the air and pressure should be transmitted without being obstructed. After familiarized with the lab instruments, the LabVIEW program for AE 460 should be started. Then, the current ambient pressure, the current ambient temperature, and a calibration coefficient for dynamic pressure correction, q correction factor, should be inputted into the program under the …show more content…
Start the testing procedure by pressing start button on the tunnel frequency control by pressing up and down buttons and increase rpm until the free stream velocity in the test section of the wind tunnel reaches 100 ft/s. For the free stream velocity to reach 100 ft/s, the rpm setting of the frequency control should be approximately 1100 rpm. Please be aware that the rpm setting for this experiment should never exceed 1500 rpm for this lab. Should the free stream velocity reaches 100 ft/s, revolve the AOA control handle until the AOA indicator shows -6 degrees. After making sure that the free stream velocity is not changed due to the blocking effect, record down data both in the LabVIEW program by pressing Record Data Point button and in the data table on paper. If the free stream velocity is changed by the blocking effect of the change of AOA, modify the rpm settings of the tunnel frequency control accordingly. Observe the surface flow by scrutinizing the location, direction and movements of the tufts; take pictures of the tufts to record down the result of surface flow
