The invention provides a voyage resistance reducing and cavitation eliminating type propeller which comprises a blade spindle 2 fixed to the rear portion of an aircraft body 1 and blades 3 fixed to the blade spindle 2, each blade 3 is of a double-layer structure and is hollow, blade water through holes 4 are evenly formed in the negative pressure face of each blade 3, the blade spindle 2 is hollow, and the blade water through holes 4 are communicated with the blade spindle 2. The propeller blade main shaft 2 is provided with a propeller blade water through hole 4, the propeller blade water through hole 4 is communicated with a cavity of the propeller blade main shaft 2, a water through main pipe 5 is further arranged in the aircraft body 1, the rear end of the water through main pipe 5 is connected and communicated with the propeller blade main shaft 2, and body water through holes 6 are further evenly formed in the front end of the aircraft body 1 and underwater parts on the two sides of the front end of the aircraft body 1. The front end of the water passing main pipe 5 extends out of the body water passing holes 6 in the front end of the aircraft body 1, and the body water passing holes 6 in the two sides of the front end of the aircraft body 1 are connected and communicated with the water passing main pipe 5 through water passing branch pipes 7. According to the invention, the sailing resistance of the aircraft can be reduced, and cavitation bubbles are eliminated.
