The invention discloses an aerial externally hung target drone nacelle, and relates to the technical field of target drone hanging. The aerial externally hung target drone nacelle is used for reducing the break rate of a target cable. The aerial externally hung target drone nacelle comprises a target cabin, wherein a turbine, an air door mechanism, an air door motor, a reduction gearbox and a winding drum are successively arranged in the target cabin; the air door motor is connected with the air door mechanism; a first rotating shaft is arranged between the turbine and the reduction gearbox; the turbine sleeves one end of the first rotating shaft; the other end of the first rotating shaft is connected with a high-speed shaft of the reduction gearbox; a second rotating shaft is arranged between the winding drum and the air door motor; the winding drum sleeves the second rotating shaft; one end of the second rotating shaft is connected with a low-speed shaft of the reduction gearbox; a self-locking mechanism which is used for locking a target drone is arranged at the bottom of the target cabin; a target cable is further arranged in the target cabin; one end of the target cable is wound on the winding drum while the other end of the target cable extends out of the target cabin and is connected with the target drone; and a target cable retracting and releasing speed sensor is further mounted on the target cable in the target cabin. The aerial externally hung target drone nacelle is used for hanging and dragging the target drone.
