According to the high lift device with the flow deflector type double-slit flap, a flow deflector is connected with a main flap through a connecting supporting arm, a containing cavity used for containing the flow deflector is formed in the rear edge of a flap cabin, a first-stage slit channel is formed between the front edge of the flow deflector and the rear edge of the flap cabin, and a second-stage slit channel is formed between the rear edge of the flow deflector and the front edge of the main flap; the flap actuator is installed on the flap cabin, and the flap supporting arm is fixed to the lower portion of the flap cabin. The flap actuator is connected with the flap supporting arm through a first connecting rod, and the flap supporting arm is connected with the main flap through a second connecting rod and a third connecting rod so that the first connecting rod, the flap supporting arm, the third connecting rod, the main flap and the flap cabin can be combined to form a four-connecting-rod mechanism in a motion plane. The four-connecting-rod mechanism is more directly and rapidly achieved, the position control precision of the rear part is higher, reliability is high, and the service life of the aircraft body can be the same.
一种带导流片式双缝襟翼的增升装置,其中,所述导流片与主襟翼通过连接支臂连接,所述襟翼舱的后缘内设置有用于包容导流片的容腔,且导流片前缘与襟翼舱后缘之间形成一级缝道,导流片后缘与主襟翼前缘之间形成二级缝道;所述襟翼作动器安装在襟翼舱上,所述襟翼支臂固定在襟翼舱下方,所述襟翼作动器通过一号连杆与襟翼支臂连接、所述襟翼支臂通过二号连杆、三号连杆与主襟翼连接以促使一号连杆、襟翼支臂、三号连杆与主襟翼和襟翼舱的组合在运动平面内形成四连杆机构,相对滑轮滑轨形式的后缘襟翼,四连杆机构实现更加直接快速,且控制后襟位置精度更高,可靠性高,能够实现与飞机本体同寿。
