The invention discloses a flying wing layout aircraft wind tunnel test body freedom degree control device and a use method thereof, and relates to the fields of airplanes, machinery and mechanics, in particular to the technical field of wind tunnel tests of airplanes. The degree of freedom of pitching, yawing and rolling of the wind tunnel test of the flying wing layout aircraft can be controlled without changing the experimental state of the aircraft. The body freedom degree control device comprises a coupler, a packaging shell, an electromagnetic clutch and a transmission shaft, the electromagnetic clutch is divided into an upper piece and a lower piece, the lower piece is fixedly installed at the bottom of the packaging shell, the upper piece is annular, and the top end of the transmission shaft is detachably connected with the coupler. The bottom end of the transmission shaft is inserted into the upper piece and rotates synchronously with the upper piece. The middle of the transmission shaft is rotationally connected into the packaging shell through a bearing. When a wind tunnel test is carried out, the pitching freedom degree can be suddenly released and locked under the condition that the load borne by a test prototype is not changed.

    本发明公开了一种飞翼布局飞机风洞试验体自由度控制装置及其使用方法,涉及飞机、机械、力学领域,特别涉及飞机的风洞试验技术领域。可以在不改变飞机所处实验状态下,控制飞翼布局飞机风洞试验的俯仰、偏航和滚转自由度。所述体自由度控制装置包括联轴器、封装外壳、电磁离合器以及传动轴,所述电磁离合器分为上下两片,下片通过固定安装在封装外壳的底部,并且上片为环形,所述传动轴的顶端与联轴器可拆卸的相连接,所述传动轴的底端则插入上片中与上片同步旋转;所述传动轴的中部通过轴承转动连接在封装外壳中。本发明进行风洞试验时,可以在不改变试验样机所受载荷的情况下对俯仰自由度突然释放与锁定。
