4.5 m×3.5m Low Speed Pressurized Wind Tunnel(FL-9)




FL-9, a low speed pressurized wind tunnel, is the unique low speed wind tunnel with high/variable-Reynolds number test capability in Asia, and its overall performance reaches international advanced level. Aviation Key Laboratory of Science and Technology on High Speed and High Reynolds Number Aerodynamic Force Research basing on FL-9 meets low speed high Reynolds number test demands of aircraft development.

Main Performance:

Test section size:4.5m×3.5m
Pressure: 0.1MPa (Atmospheric pressure) ~0.4MPa
Max velocity:130m/s (Atmospheric pressure), 90m/s (0.4MPa)
Max Reynolds number: 9.3×106


Fixed Mach/Reynolds number test, Full model/half model/component force test, Unsteady flow test at high angle of attack, Hinge-moment test, Propeller slipstream test, Parachute test, Model deformation test, Flow visualization and measurement, air intake test, LDV, TSP, PSP etc.
