Telescopic spoiling device for wind tunnel test

The invention discloses a telescopic spoiling device for wind tunnel test, comprising a windbreak base plate and wind field adjusting units. Each wind field adjusting unit includes a motor component which is fixed on the windbreak base plate; two telescopic plates are mounted on the windbreak base plate; the telescopic plates and the motor components are positioned on the same side of the windbreak base plate; the two telescopic plates are positioned on the two sides of the motor components respectively; the telescopic plates are parallel to the windbreak base plate and are slidably fitted tothe same. The telescopic spoiling device for wind tunnel test has the advantages that the motor components on the windbreak base plate are controlled to drive the telescopic plates to expand and contract through rotation of screws so as to change the specific states of the wind field adjusting units at different heights and positions, so that a wind field is adjusted; the adjusting process is convenient and takes short ti
