The invention discloses a dual-redundancy flap retracting and releasing device for aviation, and belongs to the field of flaps of fixed-wing aircrafts. The device comprises a first electric actuatingmechanism, a second electric actuating mechanism, a gear and a connecting rod. The first electric actuating mechanism and the second electric actuating mechanism are arranged in parallel and oppositely, output shafts of the first electric actuating mechanism and the second electric actuating mechanism are two racks which are arranged in parallel and oppositely, and the two racks can do reciprocating linear motion in the output axial direction of the electric actuating mechanisms; one end of the connecting rod is hinged to the gear through a shaft, and the other end is hinged to the flap through a shaft. According to the dual-redundancy flap retracting and releasing device, the aircraft flap is controlled to be retracted and released in the transmission mode that the two electric actuatingmechanisms with the racks serving as the output shafts are meshed with the gears at the same time, dual-redundancy flap retracting and releasing with the two electric actuating mechanisms serving as mutual backups is achieved, the structure is simple, and the reliability and safety of flap retracting and releasing are improved.

    本发明一种航空用双余度的襟翼收放装置,属于固定翼飞机的襟翼领域;包括第一电动执行机构、第二电动执行机构、齿轮和连杆,所述第一电动执行机构和第二电动执行机构平行且相对设置,其输出轴为平行相对设置的两个齿条,两个所述齿条能够沿电动执行机构的输出轴向做往复直线运动;所述连杆一端通过轴与所述齿轮铰接,另一端通过轴与襟翼铰接。本发明采用两个输出轴为齿条的电动执行机构同时与齿轮啮合的传动形式来操纵飞机襟翼的收起和放出,实现了两个电动执行机构互为备份的双余度襟翼收放,结构简单,提高了襟翼收放的可靠性和安全性。
