The invention discloses an air inlet channel molded surface adjusting device and a variable air inlet channel, relates to the field of air channel testing devices, and can overcome the defect that the installation and maintenance difficulty is high in the mode that a motor system or a hydraulic system is used for adjusting the molded surface of the air inlet channel to a certain extent. The air inlet duct molded surface adjusting device comprises a first deformation mechanism, the first deformation mechanism is used for changing the shape of the wall face of an air inlet duct throat, and the first deformation mechanism comprises a compression plate used for being hinged to the rear end of an air inlet duct front body, a throat straight plate hinged to the rear end of the compression plate and an expansion plate hinged to the rear end of the throat straight plate. The throat straight plate is hinged with a connecting rod, the other end of the connecting rod is hinged with a sliding block, the sliding block is hinged with the rear end of the expansion plate, one side of the sliding block is connected with a first driving piece, and the other side of the sliding block is connected with a first resetting piece; the first driving piece can drive the sliding block to move so as to adjust the angle of the connecting rod relative to the throat and other straight plates. The first driving piece comprises a first driving strip made of SMA wires.
