A propeller assembly includes a first and a second propellers. The first propeller includes a first propeller blade including a first propeller root, a first propeller tip opposite to the first propeller root, a first propeller pressure surface, and a first propeller suction surface opposite to the first propeller pressure surface. The second propeller includes a second propeller blade including a second propeller root, a second propeller tip opposite to the second propeller root, a second propeller pressure surface, and a second propeller suction surface opposite to the second propeller pressure surface. The first propeller tip is configured to extend obliquely along a span direction of the first propeller blade toward a side where the first propeller suction surface is located. The second propeller tip is configured to extend obliquely along a span direction of the second propeller blade toward a side where the second propeller pressure surface is located.
