Embodiment Construction
[0017] The invention includes steering gear, deflectors and transmission connecting rods. Several deflectors are arranged in parallel, and are installed in the duct through the rotating shafts at both ends of the deflectors. Adjacent to each other, the output shafts of the two steering gears are respectively connected to different transmission linkages through rotating rods, and one transmission linkage is hinged to a set of curved rods fixed on the deflectors to drive the angular deflection of the deflectors. Different steering gears are controlled to adjust the deflection of each set of deflectors, and through the cooperation of the two sets of deflectors, different direction control of the ducted airflow is realized.
[0018] When the angle between the guide vanes of the two groups is 0°, the guide vanes are completely closed in the duct.
[0019] The deflector airfoil is a low-speed symmetrical airfoil of the NACA series.
[0020] Each deflector is connected to the duct w...
