As shown in fig. 4d, after the thruster device is completely submerged, only the paddles rotate to generate thrust, and the air paddles do not rotate.
According to the example of the water inlet process of the amphibious aircraft, in the water inlet process of the amphibious aircraft, the rotation of the airscrew can be gradually stopped, and the airscrew is started, so that the thrust generated by the rotation of the airscrew can be used for pushing the amphibious aircraft to sail underwater.
