The invention relates to the technical field of space flight and aviation, in particular to an aircraft air inlet channel without interference on air flow, which comprises an air inlet channel body and a control unit fixedly arranged below the air inlet channel body, the control unit comprises a first air inlet valve, a second air inlet valve, a fixing frame, a motor and a transmission mechanism. The fixed frame is fixedly connected with the air inlet channel body; the first air inlet valve and the second air inlet valve are rotatably connected with the fixed frame through door shafts; the adjacent first air inlet valve and second air inlet valve are connected through a connecting rod which can be embedded in the first air inlet valve and the second air inlet valve; the connecting rod comprises an upper connecting rod and a lower connecting rod which are sequentially arranged at intervals; the motor is fixedly arranged on the fixed frame and drives the door shaft on the outermost side to rotate through the transmission mechanism. On the basis of not additionally arranging a mechanism, the flow of the air inlet channel can be changed by controlling opening and closing of the air inlet valve, so that the air inlet efficiency is improved.
