The invention provides a variable air inlet duct for collaborative jet flow of an unmanned aerial vehicle, a propeller and the unmanned aerial vehicle. The variable air inlet duct comprises a duct inner side wall and a duct outer side wall, the duct inner side wall is sleeved with the duct outer side wall, the duct outer side wall is provided with a mounting cavity, a plurality of split lips are annularly distributed at the front end of the duct outer side wall, a duct tail edge is arranged at the rear end of the duct outer side wall, the duct outer side wall, the duct inner side wall and the duct tail edge jointly define an annular channel, and the front end of the duct inner side wall and the front end of the duct outer side wall form an air blowing opening. The duct inner side wall and the duct tail edge form an air inlet; the collaborative jet device comprises a plurality of partition plates which are arranged in the axial direction of the annular channel and form a plurality of air channels communicating with the air blowing opening and the air inlet. The compression pump is arranged in the air duct; and the variable air inlet device comprises a driving assembly which is arranged in the mounting cavity, and the driving assembly is in transmission connection with the split lip and used for driving the split lip to deform forwards and downwards along the contours of the duct inner side wall and the duct outer side wall so as to change the lip airfoil.
