The invention relates to the field of aerospace, in particular to an aircraft air inlet transmission mechanism capable of adjusting throat flow in a servo mode, which comprises a gear transmission mechanism, a four-bar mechanism, a lightweight plate, a motor and a supporting column. The gear transmission mechanism comprises a small driving gear and four large driven gears meshed with the small driving gear. The four-rod mechanism comprises four lead screws, a sliding table and a sliding block connected with the sliding table. The sliding block is fixedly connected with a connecting rod; the lead screws penetrate through the light weight plate and are connected with the driven large gears in a one-to-one correspondence mode through driven shaft systems. The lead screw is fixedly arranged at the end part of the connecting rod; the motor penetrates through the lightweight plate to drive the driving pinion to rotate; the supporting columns are fixedly arranged below the light weight plate. The flow of the airplane air inlet channel can be changed in a servo mode, the structure is stable, operation is easy, and the air inlet flow control precision is high.
