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
