Non-similar dual-redundancy servo device for aircraft air door

The invention belongs to the technical field of aviation accessories, and particularly relates to a dissimilar dual-redundancy servo device for an aircraft air door, which comprises a motor, a control mechanism, a pneumatic mechanism and a control assembly, the control mechanism compatible with electric control and pneumatic control is arranged in the device, so that redundancy control of the air door of the aircraft under different control modes is realized. Electric control and pneumatic control can be switched in a compatible mode, the control failure problem caused by similar faults is reduced, and therefore the reliability of a control system is improved, and the flight safety is greatly improved. 本发明属于航空附件技术领域，具体涉及一种用于飞机风门的非相似双余度伺服装置，包括电动机、操纵机构、气动机构以及控制组件；本发明通过在装置中设置具有电动操纵与气动操纵相兼容的操纵机构，实现飞机风门在不同操纵方式下的多余度控制。电动操纵与气动操纵之间可兼容切换，降低因相似故障引发的操纵失效问题，从而提高控制系统的可靠性，大大提高了飞行安全性。
