The invention provides an aircraft air brake based on an airfoil profile. The aircraft air brake comprises a fuselage, an air brake body, a first actuating cylinder and a second actuating cylinder, a containing groove is formed in one side of the machine body, and the speed brake body is movably connected with the containing groove. One end of the first actuating cylinder is connected with the containing groove, the other end of the first actuating cylinder is connected with the bottom of the speed brake body, one end of the second actuating cylinder is connected with the containing groove, and the other end of the second actuating cylinder is connected with the middle or the top of the speed brake body. The longitudinal section of the speed brake body is in an inverted wing shape. During working, the first actuator cylinder is started, the front edge of the brake body is raised, and it is guaranteed that the front edge of the brake body protrudes out of a fuselage by a certain height; the second actuating cylinder is started, so that the air brake body rotates to an opening and closing angle around the fulcrum of the first actuating cylinder on the air brake body; and carrying out wind tunnel force measurement tests with different opening and closing angles relative to the flat brake. The resistance increasing effect is obvious, and high practicability is achieved.

    本发明提供了一种基于翼型剖面的飞行器减速板,包括:机身,减速板本体,第一作动筒和第二作动筒;所述机身一侧设置有容置槽,所述减速板本体与所述容置槽活动连接;所述第一作动筒的一端与所述容置槽连接,另一端与所述减速板本体的底部连接,所述第二作动筒的一端与所述容置槽连接,另一端与所述减速板本体的中部或顶部连接;所述减速板本体的纵向剖面为倒置的翼型。工作时,启动第一作动筒,抬高减速板本体前缘,保证减速板本体前缘突出机身到一定高度;启动第二作动筒,使减速板本体绕第一作动筒在减速板本体上的支点旋转到开合角度;开展不同开合角度相对于平板减速板的风洞测力试验。本发明增阻效果明显,具有很强的实用性。
