Abstract

The paper presents results of the numerical analysis of propulsive characteristics of full-submerged Archimedes screws of rotary-screw propulsion units of snow and swamp-going amphibious vehicles with the most typical geometric characteristics for this class of vehicles. The received performance curves and the pictures of visualization of interaction between water environment and Archimedes screws with different helix angles are given. The maximum available values of efficiency determinants of Archimedes screws for cruising and mooring modes are determined. The results of comparative analysis of efficiency of Archimedes screws and propellers with the same operation conditions are considered. The ways to increase the efficiency of rotary-screw propulsion units of snow and swamp-going amphibious vehicles according to the results received are designated. The results and the conclusions obtained as part of the study could be used by developers of amphibian with rotary-screw propulsion units to estimate and provide the overwater characteristics.
