MAE 357 SEC 205 Experimental Aerodynamics I NCSU Alejandro Merizalde Tunnel and Pressure Transducer Calibration In this experiment, one undergoes the procedure of calibrating the N.C. State Subsonic Wind Tunnel by analyzing the test section velocities and Scannivalve pressure transducers. Procedures and Results obtained through out the process are discussed in detail and illustrated using Tecplot360.

Apparatus and Procedure The N.C. State Subsonic Wind Tunnel is composed of a low speed loop system and with a DC motor at one end. In the converging area of the wind tunnel, the pitot-static tube sits hanging from the ceiling facing the incoming wind pressure. A water manometer and a pressure transducer are setup directly to the wind tunnel in order to obtain data. Similarly, a computer setup outside of the wind tunnel is connected to the P305 inside. The Diaphragm Pressure Transducer used is the Validyne Xder P305D. As described by the manufacturer, this “Pressure Transducer is designed for direct application in DC strain gage instrumentation systems which require low pressure ranges not generally available in strain gage transducers. Functionally, it is a direct replacement for a strain gage transducer, providing a 5 mV/V nominal DC output over an excitation range of 5 to 12 Vdc. “ In order to turn on the Wind Tunnel, on must activate the five different levers in ascending sequence. At this point the Wind Tunnel is on and the blades begin to turn. For
