The invention discloses a self-adaptation system for detecting anti-wind capability of an unmanned plane. The self-adaptation system for detecting anti-wind capability of an unmanned plane includes a wind field analog apparatus and an anti-wind test system, wherein the wind field analog apparatus provides a wind field environment with changeable direction and wind speed for the anti-wind test system; the anti-wind test system includes an unmanned plane test mechanism and a control feedback system; the unmanned plane test mechanism includes a support frame for fixing an unmanned plane, a flexible mechanism which maintains the support frame to rotate freely, a mobile platform for bearing the flexible mechanism, and a support base for supporting the mobile platform; the control feedback system includes a control system, a wind speed feedback unit for detecting the real time wind speed, and an unmanned plane attitude and heading reference unit; and the control system receives the data from the wind speed feedback unit and the unmanned plane attitude and heading reference unit, and according to the real time detection wind speed and the detected flying state of the unmanned plane, changes the wind speed and wind direction provided by the wind field analog apparatus and determines the maximum wind speed which can be resisted by the unmanned plane.
