Title: Method for mutually reversely rotating plurality of propellers arranged in parallel and tandem
Inventor: NAGATA TAKAHISA
IPC: B63H5/10
Filed: 2001-09-05
Abstract: PROBLEM TO BE SOLVED: To prevent racing of a propeller, increase propulsion efficiency and miniaturize the propeller by reducing propelled bodies such as air and water generated in a periphery of the rotating propeller and rotating along with the propeller. SOLUTION: An unladen freely rotating propeller is installed in front or rear of a propeller connected to power.
