The invention discloses a retractable strake wing of an empennage-free body fusion layout aircraft, and belongs to the field of aerodynamic layout design of aircrafts. The retractable edging wings are located on the two sides of a fuselage of the wing body fusion layout aircraft and are retracted and released by rotating around a shaft. The horizontal projection of the retractable edging wing in the folded state is defined by three side lines. The outer side line, far away from the symmetry plane of the fuselage, of the horizontal projection is an arc line and coincides with the ridge of the side edge of the fuselage, the distance L1 between the two end points of the arc line is 0.4 L, and the distance L2 between the end point, close to the wing root, of the arc line and the front edge point of the wing root is 0.02 L. And the length L3 of the straight side at the rear part of the horizontal projection is 0.16 L. The inner side line of the horizontal projection close to the plane of symmetry of the fuselage is a straight line. L is the horizontal projection length of the chord line of the wing root. While the low-speed large-attack-angle lift force of the whole aircraft is increased, the head-up torque can be generated, and the torque balancing difficulty is reduced. The structure is simple, and the whole-machine structure weight can be effectively reduced.

    一种无尾翼身融合布局飞机的可收放边条翼,属于飞行器气动布局设计领域。所述可收放边条翼位于翼身融合布局飞机机身两侧,通过绕轴旋转进行收放。所述可收放边条翼收起状态下的水平投影由三条边线围成。所述水平投影远离机身对称面的外侧边线为弧线,且与机身侧缘棱线重合,所述弧线两端点之间的距离L1=0.4L,所述弧线靠近机翼翼根的端点与机翼翼根前缘点的距离为L2=0.02L。所述水平投影后部直边的长度L3=0.16L。所述的水平投影靠近机身对称面的内侧边线为直线。所述的L为机翼翼根弦线的水平投影长度。本发明增加全机低速大攻角升力的同时,可产生抬头力矩,降低了力矩配平难度。结构简单,可有效降低全机结构重量。
