The invention discloses an aircraft elevator with a T-shaped microstructure, and an airplane horizontal tail wing. The aircraft elevator and horizontal tail wing comprises a control surface and the T-shaped microstructure connected to the rear edge of the control surface and used for generating local vortexes on the rear edge of the control surface. The T-shaped microstructure comprises an upper vertical plate, a lower vertical plate, a connecting plate, an upper reinforcing chamfer and a lower reinforcing chamfer and is made of aviation aluminum. The lower end of the upper vertical plate andthe upper end of the lower vertical plate are respectively connected with one end of the connecting plate; the connecting plate is connected with the upper sheath and the lower sheath of the control surface through adhesive; the upper vertical plate and the lower vertical plate protrude out of the upper side and the lower side of the rear edge of the control surface respectively. The T-shaped microstructure with the scale being 1% of the total length of the empennage section is installed on the rear edge of the control surface, local airflow separation vortexes are generated, the equivalent length of the wing surface streaming characteristic is increased, wing surface pressure distribution is changed, and the control surface control efficiency is obviously improved.

    本发明公开了一种具有T形微结构的飞机升降舵和水平尾翼,包括舵面和连接在舵面后缘用于在舵面后缘产生局部涡流的T形微结构;所述T形微结构包括上垂板、下垂板、连接板、上加强倒角、下加强倒角,材料为航空铝材;所述上垂板下端、下垂板上端分别与连接板一端连接,连接板与舵面上下蒙皮采用胶粘连接;所述上垂板和下垂板分别凸出舵面后缘上、下侧;本发明通过在舵面后缘安装一个尺度在尾翼剖面总长的1%量级的T形微结构,产生局部气流分离涡,使得翼面绕流特性的等效长度增加,改变了翼面压力分布,明显提升舵面操纵效率。
