The invention discloses a fixed-wing aircraft which comprises an aircraft body, a flight control computer, an attack angle sensor, a sideslip angle sensor and a slope sensor are arranged on the aircraft body, and the attack angle sensor, the sideslip angle sensor and the slope sensor are connected with the flight control computer. The main wings are symmetrically installed on the two sides of the aircraft body, and the front edges of the main wings are swept back. The rear edge of the main wing is swept forward; pneumatic control surfaces which are controlled by a flight control computer to deflect are symmetrically mounted at the rear edge positions of the main wings on the two sides; tail fins which are controlled by a flight control computer to rotate are symmetrically mounted on the two sides of the tail of the aircraft body, and the rotating axes of the tail fins are swept back; the sweepback angle of the rotation axis of the tail fin is larger than or equal to the sweepback angle of the front edge of the main wing, and the chord plane where the tail fin is located is parallel to the chord plane where the front edge of the main wing is located or the included angle between the two is smaller than 15 degrees. Effective yaw stabilization and yaw control of the fixed-wing aircraft under the condition of no vertical empennage can be realized through pneumatic surface control in all the modes.

    本发明公开了一种固定翼飞行器,包括飞行器本体,其上设有飞行控制计算机及与所述飞行控制计算机连接的迎角传感器、侧滑角传感器和坡度传感器;主翼对称安装在所述飞行器本体两侧,且其前缘后掠;所述主翼后缘前掠;在两侧所述主翼的后缘位置处对称安装有通过飞行控制计算机控制偏转的气动控制面;在所述飞行器本体尾部两侧位置处对称安装有通过飞行控制计算机控制转动的尾鳍,所述尾鳍的转动轴线后掠;所述尾鳍转动轴线的后掠角大于或等于所述主翼前缘后掠角,所述尾鳍所在的弦平面与所述主翼前缘所在的弦平面平行或二者夹角小于15°。本发明在前述所有模态中均能通过气动面控制实现无垂直尾翼条件下对固定翼飞行器有效的偏航安定和偏航操纵。
