摘要：【中文】本发明实施例提供一种大中型飞机的双铰链方向舵结构，包括：前方向舵(1)和后方向舵(2)；前方向舵(1)连接在飞机的垂直安定面后缘悬挂支臂上；后方向舵(2)连接在前方向舵(1)上。该双铰链方向舵结构由前方向舵结构与后方向舵结构两部分组成，后方向舵的偏转角度为前方向舵的2倍。该双铰链方向舵结构增大了方向舵的舵面面积和偏转角度，提高了飞机的航向修正和转向速度。 【EN】The embodiment of the invention provides a double-hinge rudder structure of a large and medium-sized airplane, which comprises: a front rudder (1) and a rear rudder (2); the front rudder (1) is connected to a suspension support arm at the rear edge of a vertical stabilizer of the airplane; the rear rudder (2) is connected to the front rudder (1). The double-hinge rudder structure consists of a front rudder structure and a rear rudder structure, wherein the deflection angle of the rear rudder is 2 times of that of the front rudder. The double-hinge rudder structure increases the control surface area and the deflection angle of the rudder, and improves the course correction and the steering speed of the airplane.
