Aircraft control system

The invention discloses an aircraft control system and relates to the technical field of aircraft control system design. The aircraft control system comprises a first tail vane, a second tail vane, a first coupling rocker, a second coupling rocker, a driving connection rod, a decoupling rocker, a first decoupling connection rod, a second decoupling connection rod, a course control device and a longitudinal control device. The course control device is used for driving the first coupling rocker. The longitudinal control device is used for driving the second coupling rocker. The first coupling rocker is coupled to the second coupling rocker coaxially. The first coupling rocker is hinged to one end of the driving connection rod. The second coupling rocker is connected with a rotary shaft of the decoupling rocker. The decoupling rocker comprises an input end and two output ends. The input end of the decoupling rocker is hinged to the other end of the driving connection rod. The first decoupling connection rod is used for being connected with one output end of the decoupling rocker and the first tail vane. The second decoupling connection rod is used for being connected with the other output end of the decoupling rocker and the second tail vane. The aircraft control system has the beneficial effects that course control and longitudinal control can be achieved simultaneously, and structure is simple.
