Development of Variable Vector Propeller : 1st Report

Abstract

Submersibles such as Remotely Operated Vehicles (ROV), manned submersible, which have been proven effectively in the fields of offshore oil environment, deep ocean research, etc., are necessary for high maneuverability at low speed. And all submersibles today are propelled and controlled by single dimension devices such as screws, planes. As for Variable Vector Propeller of three dimentional device based on varying propeller pitches both collectively and cyclically, we carried out the model tests on its performance and confirmed its characteristics, which are fairly suitable to the theoretical estimation. By using this type of propeller, it certainly seems to be able to reduce propellers and consquently to contribute to the compactness and the light we light of ROV, etc.. We have been confirming and examining the mecanical characteristics of collective and cyclic pitch changes, controls, etc., and at high pressure, using the experimental model specially manifactured for this purpose. We will report these results in the 2nd report.
