The development of helicopter vertical flight test rig in Φ5m vertical wind tunnel

Helicopter vertical flight test rig was developed in Φ5m vertical wind tunnel of Chi na Aerodynamics Research and Development Center. The helicopter vertical flight test rig has the abilities of remote control on rotation speed, tilt angle, collective pitch and periodic pitch. Blade tip Mach number similarity test can be conducted with rotor model of 2m to 3m diameter. Ac- cording to the test data acquired, the helicopter vertical flight test rig has good ability and per formance of rotor model vertical flight testing. It can be used to conduct helicopter vertical flight performance test and flow mechanism research.
