Embodiment Construction
[0032] This embodiment is a continuous transonic wind tunnel airfoil dynamic experiment average angle of attack adjustment mechanism, including a base, an oscillation shaft support 15 , an oscillation shaft and an oscillation shaft adjustment plate 7 . The base is divided into an arc base 9 and a horizontal installation platform 16 ; the oscillation axis includes a first oscillation axis 4 , a second oscillation axis 6 and a third oscillation axis 8 . in:
[0033] The horizontal installation platform 16 is fixed on the upper surface of the arc base 9 by screws; the arc surface of the arc base is in contact with the surface of the wind tunnel rotating window casing, and is fixed on the inner surface of the wind tunnel casing by bolts. Three oscillating shaft supports 15 are arranged outside the two ends of the wind tunnel rotating window 11, and the oscillating shaft support located outside one end of the wind tunnel rotating window is used to support the first oscillating shaf...
