1.2 m Trisonic Wind Tunnel (FL-2, FL-60)




FL-2 and FL-60, with the same test section size, are mainly used to perform high speed aircraft aerodynamic test.
FL-2, a blow down trisonic wind tunnel, is one of four Chinese 1.2m test section trisonic wind tunnels and important research facility of Aviation Key Laboratory of Science and Technology on High Speed and High Reynolds Number Aerodynamic Force Research. FL-60, a blow down trisonic wind tunnel, is mainly used to test M2.0~4.0 supersonic aircrafts including near space aircraft, aerospace plane, missile etc., besides, industrial test of subsonic, transonic and supersonic aircrafts below M2.0 .

Main Performance:

Test section size:1.2m×1.2m
Nozzle: solid nozzle (FL-2), flexible nozzle(FL-60)
Mach number:0.3~4.0(FL-2: 0.3~2.0, FL-60: 0.3~4.0)


Conventional force test/pressure test, Air intake test, Unsteady flow test at high angle of attack, Dynamic derivative test, Large amplitude oscillation test, External Store force test, Component force test, Hinge-moment test, Half model supporting, Aeroelasticity Simulation, CTS, PSP, TSP, IR, Schlieren and etc.
